Chick-watching at Bøtø
The ringing
Today it was mostly recaptures in the ringing and not many birds, just nine in total. The weather forecast looked a bit unstable but the rain of the night had stopped just before net opening time and during the five standard hours, there was just a very short shower that hid the ringing garden so I just walked the round while it rained and it stopped very soon, as I had already seen on the radar. I was not bored this morning though, as I had a very interested visitor who joined me on the rounds today. One the two friends of my mother, who are spending some holiday days at Denmark with her and visiting me, Christian from Munich, wanted to see the ringing. Luckily, there were some birds I could show to him and the rest of the time, I explained about the migration behaviour of long-distance and short distance migrants as well as of birds was the Blackbird “Solsort”, that we can actually see all year round, but they also do migrate shorter distances. The Blackbird, “Solsort”, that you fed in your garden in winter might be a bit further noth now in spring, Maybe just in northern Denmark or also in Sweden or Norway, while some Blackbirds “Solsort” that were wintering in Germany are here. There were also some moths in the traps that kept me busy.

The moths
There were 17 different moth species in the two light traps I am catching with now. Some of them I recognized but there were also some new. My favourite species of today was Noctua pronuba “Stor Smutugle”. The English name is Large Yellow Underwing. This is a quite good name as what I think is especially pretty on them is their orange (not yellow though, but there might be variation) underwing, that you see when releasing the moth by the time it flies away. It should be a very common species though, so there will probably be more the next days. Another new moth was Phragmataecia castaneae ”Rørborer”, which is called Reed Leopard in English, a quiet funny name. I think for a rainy night as toady this is an okay amount of moth species caught, and at Bøtø, I saw many moths flying and could identify two more species.

Birds in the area
After all the morning work was done, Gert and I showed Bøtø to my mother and her friends. The topic of the trip was mainly chicks, we saw Crane “Trane” with their chicks, Avocets “Klyde” and their chicks and there are also young Oystercatchers “Strandskade” and White-tailed Eagles “Havørn” to admire.

News of the station
Jens arrived this evening, he will be here for ringing for a bit more than a week. There is the Overshooter event this weekend, so we host a few birders over the weekend, who are hoping to see some good birds the nest days. Jasper also got family visit and they will explore Denmark a bit the next days, but he will be back on Monday.

Grønirisk couples
The ringing:
Today there were quite a lot of recaps in the nets, but it was also some from last year or the year before. It is always nice to realize when entering data, that these birds returned to here for breeding. If it is breeding birds, we realize that on their brood patches, we often see on birds we catch at this time of year. Today we had both of the common Acrocephalus Warblers, Marsh Warbler "Kærsanger" and Reed Warbler "Rørsanger", but I think the highlights of today were two couples of Greenfinches "Grønirisk", both Robert and I found one couple of male and female together in the net.
Marsh Warbler "Kærsanger"
The moth:
Last night and early morning were good for catching moths. In total 22 species and 6 new ones. That is what looking for moths makes it interesting, every day something new. I have chosen to show you the two following moths: the Straw Dot (Lille Å-Ugle) and the Common Yellow Conch (Tidselgulvikler).
This was my last day in Gedser for the spring, but will be back in September. Hanelie will probably go further with the moths, I have been able to get her interested in this intriging group of animals.

Again very few birds
About the birds is not much to mention today. Only 8 birds were flying in the nets (see table). At the point Hanelie saw a Corn bunting and a Bee-eater was flying over the garden.
The moths were slightly less abundant, but still we had 17 species and 3 of them were new for the season at this location (bold in the table). Of two of the new ones a picture is presented below: it is the Båndet Tyv (Middle-Barred Minor) and the Benvedmåler (Scorched Carpet).

Is this the weather change we were hoping for?
- Ringmækening:
After checking the radar we found out that it was possible to open the nets before the rain came. First and second round were zero rounds though and the closing round brought one Icterine Warbler “Gulbug”. Later in the morning when the rain stopped, it was possible to open again, but it was not worth it, we did not get a second bird. Even though rainy days are not the most interesting, we are welcoming this weather change, it might bring some birds, when the bad weather front is over.
Todays one and only bird: A Icterine Warbler "Gulbug"
Catching moths was not influenced by the rain. We caught 21 species and again 5 new species for the season at this location. To catch every day new species is not so strange. In my garden I have caught more than 500 species in 3 years time. It is amazing how many species are flying around in the night. Because of the single bird we had today I will show a few more moths than usually. I have selected the following species: Elephant Hawkmoth (Dueurtsværmer), Maidens Blush (Ege-Bæltemåler), Green Oak Tortrix (Egevikler) and the Black-veined Moth (Hvidvingemåler).

The overcasted sky brings some little surprises in the nets
Ringmærkening:
The weather forecast for this morning was a little unstable but and although we heard it thundering and saw amazing lightening scars on the sky, the rain just hit us very shortly so we could keep the nets open for the whole standard time. The sky was overcasted the during the whole morning and we opened the nets at the pond. They did not catch anything so far, but for today, it was a good decision. Two Skylarks “Sanglærke” went into one of the nets. We are hearing them every day all around, but they usually do not go into our nets. So they were a little highlight of the morning.
Skylark "Sanglærke"
Also the Sparrowhawk-nets were productive today. No, we did not catch Sparrowhawks but a Barn Swallow “Landsvale” and a Hawfinch “Kernebider” went in these nets today.

Hawfinch "Kernebider"
Else, we caught the 8th Common Rosefinch “Karmindompap” for the season today. In total, we had 17 new birds of 11 species, but some little surprises in the nets so it was a quite nice morning.
The moth: Also the moths were doing well this night, there were quite some in the traps and on the walls. 25 Species and 5 new for the season (bold in the table). In contrast to the more brown or darker moths till now we had a few very colourful ones. One was light green, the Perlemåler, and one was yellow with a few darker patches, the Citronmåler.

Nyt fra stationen: Ole left us this mornig but he will be back again for a short stay in two weeks.
In the afternoon, I got visitors from home, my mother arrived with two friends from Munich. She will stay here with us until the 1st of June.

The ringing:
It was rather quiet in the garden when we went to open the nets. This is not the best sign and indeed, there were not many birds in the nets to ring. Nice was the 7th Common Rosefinch "Karmindompap" in one of our nets. The Common Rosefinch "Karmindompap" is a rare breeding bird in Denmark. It is usually observed in the last week of May to early June, so there is still the possibility for more to come. While the population was stable in the 1980s and 1990s, it declined drastically in the last decades. The good number of Rosefinches "Karmindompap" in our nets might indicate, that the population is recovering. Of course, this could also just be a phenonemon of this spring, but it gives reason for hope.
Nevertheless, today not a picture of a Rosefinch "Karmindompap" but of a Garden Warbler "Havesanger". The Latin name of the species is Sylvia borin, but it is everything other than boring. This little bird of about 13-14 cm and about 18 gramms came all the way from its wintering grounds in tropical Africa here to Denmark to its breeding grounds as more food ressources are available here to hatch its young. After they are grown and both adults and juveniles moulted some of their feathers, they will fly the long way back to Africa!

Moths: We found 22 species in the traps or on the walls behind the traps. Three new species for the season (bold ones in the table). I have chosen to show two of the so called micro moths, they have no Danish name but are common moths: Aethes smeathmanniana and Aspilapterix tringipennella. Aspilapterix has very long front legs and Aethes has a complete diferent appearence. They are chosen to show the large variability in the world of the moths.

Trækket ved Odden: En smuk søndag på Odden med smukt vejr, fint selskab af fuglefolk og lidt uventet træk ude over havet. Der var flokke af terner, blandt andet en Rovterne (Hydroprogne caspia) samt en Alk (Alca torda) og en Almindelig Kjove (Stercorarius parasiticus) med de karakteristiske forlængede midterste halefjer for lidt ældre fugle af arten. Desuden var der lidt træk af svømmeænder i vestlige og sydvestlige retninger.
Trækket blev på den måde ganske varieret med flere arter end i de seneste forudgående dage, men tallene var små og udtryk for, at det store forårstræk formentlig sluttede med det store ryk af Mørkbugede Knortegås (Branta bernicla bernicla) torsdag eftermiddag og aften 23. maj.
I den forløbne uge kom tusindvis af Mørkbugede Knortegæs (Branta bernicla bernicla) ind over det sydlige Danmark i eftermiddags- og aftentimerne efter formiddagens store regnvejr, men det havde ikke nødvendigvis noget med regnfronten at gøre. Tre Mørkbugede Knortegæs med GPS-sendere tyder snarere på, at tiden blot var inde for knortegæssene til at indlede trækket mod ynglepladserne, og det foregik meget intenst.
En Mørkbuget Knortegås med GPS-sender, som havde overvintret ved den hollandske ø Texel var stadig på øen, da der kom et signal fra senderen torsdag 23. maj klokken 5:25, men klokken 6:39 viste et signal fra den hollandske del af Vadehavet, at den havde indledt sit træk, som fortsatte ind over Tyskland. Den passerede sydspidsen af Langeland klokken 18.09 og fortsatte nord om Lolland ind over Sydsjælland, hvor der kom et signal fra senderen ved Feddet klokken 20.09.
En anden Mørkbuget Knortegås med GPS-sender trak også fra en overvintringsplads i Holland kom først 24. maj, dagen efter den rengfyldte torsdag, men fulgte næsten samme rute over Danmark med signaler ud for Sydlangeland klokken 3:45 om morgenen. Den fløj op langs Langeland og var ved nordspidsen klokken 5.45, hvorfra den fortsatte mod Sjælland og trak ud over Feddet klokken 7:01.
En tredje Mørkbuget Knortegås med GPS-sender var stadig i vinterkvarteret nord for Brest i det nordvestligste Frankrig 21. maj klokken 17.16. To timer senere kom der signal fra gåsens sender klokken 19.17 et stykke ude over havet mod nordøst. Den fortsatte gennem den Engelske Kanal og Vadehavet og blev registreret lige nord for Kiel i Tyskland 23. maj klokken 9:36 på vej mod torsdagens regnvejr. Der kom to signaler fra den klokken 14:36 i Femer Bælt syd for Nakskov på Vestlolland, og klokken 18:36 fløj den ganske tæt på kysten lige ud for det sted ved Saksfjed-Hyllekrog, hvor der blev talt et stort træk på det tidspunkt. Den fortsatte tværs over Falster og blev registreret et stykke syd for Møn klokken 19:36.
Alle tre gæs er nu langt inde i Rusland på vej mod Sibirien efter nogle få hektiske døgn, hvor de højst har rastet et par gange i nogle få timer.
Fælles for dem har været, at de Mørkbugede Knortegæs tilsyneladende har lidt forskellige ruter ind over det sydlige Danmark og Sverige, men alle derefter har fulgt samme rute op gennem farvandet mellem det svenske fastland og Öland, videre mod nordspidsen af Gotland, hvorfra de har fulgt sydkysten af Finland mod Rusland – altså en fast rute med de to store svenske øer som faste orienteringspunkter.
På land var morgenens store overraskelse en Skovmår (Martes martes), som vi opdagede helt ude på kanten af kystskrænten, da krager i området pludselig var unormalt ophidsede. Måren kom pilende hen mod os på flugt fra kragerne, men vendte om, da den fik øje på os, og forsvandt tilbage, hvor den kom fra. Skovmåren findes i hele Danmark, men er et sjældent syn.
Fugle behøver ikke at være sjældne for at være fantastiske oplevelser. Tornirisken (Linaria cannabina) på Gedser Odde er en flot lille finke, som man kan glæde sig over mange steder i Danmark. Foto: Ole Friis Larsen/GFU

Biæder i luften
The ringing:
This morning, we caught 13 birds, 9 of them were new, in total we had 9 species. The highlight was a new Rosefinch “Karmindompap”! Already the 6th for the season, that’s three times as much as the Bird observatory caught last year.
Common Rosefinch "Karmindompap"
But all in all, a slow morning.
Is this spring just exceptionally bad? Also the other Danish bird observatories notice low numbers of birds in the nets. Every day, we are printing out the daily report of birds we ringed that day, but it also shows the number of each species in the season and the total number of birds ringed in the season. That made me curious and I started to compare this spring season to 2023´s spring season. I was surprised finding out, that actually, this season, we ringed 322 more birds than last year. The reason for that was an exceptionally good March. While on the 31 of March 2023, 737 birds were ringed at Gedser Fuglestation, it was 1423 this year! In fact, the abundance of especially Goldcrests “Fuglekonge” as well as Great Tits “Musvit” and Blue Tits “Blåmejse”, but also Firecrest “Rødtoppet Fuglekonge” and Blackbird “Solsort” was very good this March. 213 Goldcrests “Fuglekonge” in 2024 compared to 66 in 2023. 342 Great Tits “Musvit” this March compared to 65 in 2023. 183 Blue Tits “Blåmejse” in March 2024, it was 26 in 2023.
Great Tit "Musvit"
Just one species seemed to be a bit behind in March 2024, which is the Wren “Gærdesmutte”, 133 Wrens were winged in March 2023 while it was just 75 this year.
But April and May 2024 indeed had less birds than in 2023: 872 birds were ringed in April 2023 while it was just 591 this year, 524 birds were ringed on the 25th of May 2023, this May, it is just 451 birds.
So I was expecting it to be the long-distance migrants, that are missing in abundances. But I was wrong with that. Comparing the data of April 2023 to April 2024, I noticed, that many birds had arrived quite early this year. Especially Willow Warbler “Løvsanger” and Lesser Whitethroat “Gærdesanger”, to Africa-migrants, arrived quite early this year. While in 2023, just 6 Willow Warblers were caught in the nets by the end of April, it was double the number in 2024: Twelve individuals already caught in the nets. 2023, the station just caught just 11 Lesser Whitethroats “Gærdesanger” by the end of April, this year it was 41. Also birds, that are migrating shorter distances, as Chiffchaff “Gransanger” and Blackcap “Munk” were not doing bad this spring, compared to last years` spring. So which birds were missing this April? It was the Dunnock “Jernspurv” that I noticed was caught in bigger abundances last year: 222 birds in 2023 while it was just 89 in 2024. And again, the Wren “Gærdesmutte” was low in April, just 42 birds this April while it was 93 Wrens in April 2023.
Looking at May, it was also not really the long-distance migrants that are missing. The only species that looks quite low this May is the Common Whitethroat “Tornsanger”, we nearly had double the amount by that time last year: 63 Common Whitethroats “Tornsanger” in May 2023 and just 33 this year. But the abundance of Dunnocks “Jernspurv” is very low this May (And this whole spring). Just 20 Dunnocks “Jernspurv” were ringed this year while it was 141 in May 2023.
So it seems that it is actually these little brown and inconspicuous birds as Wren “Gærdesmutte” and Dunnock “Jernspurv” that we are missing and it is not our long-distance migrants, that are stuck somewhere in more southern parts of Europe or did not even return from their wintering grounds.
It might just be the cold spring weather and the constant winds from easterly direction, without big weather changes, that make this spring appear so slow, as the missing weather changes do not bring waves with new birds. They just all drip in slowly… And maybe Wren “Gærdesmutte” and Dunnock “Jernspurv” have had bad breeding success last year?
Lets see how it develops. There are still some weeks to go until the end of the spring season. Still birds on the way. And all in all, we are not low in numbers of birds in the nets. A slow April after a exceptional good March and not the best May. And some species are doing quite well, look at the Rosefinch “Karmindompap”!
Moths: Today 19 moth species of which 6 were new for the season (bold in the table below). The Ege-månemåler was the absolute highlight. In Naturbase there are only three entries of before 2014. The species is rarely seen and is sometimes attracted to light late in the night (site of the Vlinderstichting). It is according to the books mostly found in Lolland, Falster and Møn, but only single observations. It was also for me a new species.

Trækket på Odden: Lidt mere vind fra nordøst og skyer gav en koldere morgen end forventet, og tallene var så små, at det var svært at afgøre med sikkerhed, hvilke bevægelser der var reelt træk eller bare lokale flytninger, selv om der var en del åbenlyse trækfugle i området. I krattet på Odden sang en Kærsanger (Acrocephalus palustris) en Havesanger (Sylvia borin) og en Karmindompap (Carpodacus erythrinus), som egentlig ikke hører til på lige netop den biotop. Det var ganske givet trækfugle, som bare holdt pause der.
En Bjergvipstjert (Motacilla cinerea) og en Grå Fluesnapper (Muscicapa striata) hørte naturligt til på Odden, men brugte den blot som rasteplads.
Der er stadig fugle på reelt træk mod ynglepladser, men en del af de fugle, vi ser nu, er unge fugle fra sidste år, som ikke er ynglemodne endnu, som denne Røde Glente (Milvus milvus) ved Gedser Odde lørdag morgen - bemærk ungfuglens røde kropsfjer med lyse spidser, som de voksne/adulte ikke har. Den slags fugle strejfer nu omkring. Glenten fandt i øvrigt noget at æde på marken til stor fortrydelse for en lokal Gråkrage (Corvus cornix), som gerne ville have haft den luns for sig selv. Foto: Ole Friis Larsen/GFU
På vandet svømmede en Havlit (Clangula hyemalis) alene langs stranden. Den burde være væk nu på vej mod nord, men var måske ikke helbredsmæssigt på toppen til den anstrengende tur. Den lange hale burde stritte opad, men hang bogstaveligt talt i vandskorpen.
Havlitten ved stranden var formentlig ikke klar til trækket og kom ikke med, da alle de andre tog af sted. Foto: Ole Friis Larsen/GFU
Da vi lukkede for tælleriet og gik hver til sit, hørte og så Louis A. Hansen på vej ind mod Gedser en Biæder (Merops apiaster) i et træ ved vejen. Flere andre nåede at opleve fuglen, før den sidst blev hørt kalde på vej ud mod Odden. Da vi spiste ude fredag aften i fuglestationens have mente nogle af os også, at vi hørte en Biæder, men vi slog det hen som formentlig en efterligning i sangen hos en Guldbug (Hippolais icterina) i haven – måske var det alligevel en Biæder allerede da, og med lidt held får vi den måske at se på Odden søndag morgen.
Mens vi ledte efter Biæderen, så vi to fine hanner af sommerfuglearten Aurora (Anthocharis cardamines). Der er altid noget at opleve i naturen. Foto: Ole Friis Larsen/GFU

Tigerspinder og Silkevinge
The ringing:
This morning brought a little improvement compared to the last days, we had 18 new birds of 9 species. Two of dem were Rosefinches “Karmindompap”! In total, we had 5 this season now, this is more than double than last year, in which just two were caught. The Rosefinches are apparently doing well here! After ringing the juvenile/ ad. female that I had, I took a picture, but was a bit afraid, that you would be bored of seeing the same species in three following blogposts. But Robert alleyed my worries, as he got a male with quite some red the next round!
Rosefinch "Karmindompap"
We also caught some Marsh Warblers “Rørsanger” and Redstarts “Rødstjert”.
Redstart "Rødstjert"
While it was a bit foggy with a lot of moisture in the air in the first rounds, the sun come out in the last rounds and it slowed completely down.
Sun on the spider nets
Tomorrow is another day with low winds from north-east.
Let´s see, what it will bring!
Today again some moths. 17 species and 4 new ones for the season (bold in table). Two were particular nice (the Tigerspinder and the Silkevinge) and the last one has even a very particular shape (see pictures).
Almindelig Tigerspinder (in English the White Ermine)
Silkevinge (in English the Chinese Character)
Trækket på Odden: Fredagens vigtigste observation på Odden var uden tvivl en hunfarvet Blåhals (Luscinia svecica), som Benjamin Bechgaard Lisse så i krattet langs pynten. Den var ikke ringmærket, så det var ikke den samme fugl, som forleden blev fanget inde i fuglestationens have, og derfor tyder de to fund tilsammen på, at arten måske for alvor er ved at finde vej til Lolland og Falster. Fuglen i krattet var med sikkerhed en hun, fordi selv unge hanner fra sidste år nu har noget blåt på brystet. Vi kunne derfor roligt kalde den en hun 2k+ - altså en hun i sit andet kalenderår eller ældre.
Blåhalsen uden blåt på brystet er på dette tidspunkt med sikkerhed en hun, fordi også unge hanner i løbet af vinteren får en del blåt på brystet. Nogle voksne/adulte hunner får lidt blåt på brystet, andre ikke, så vi kan ikke sætte en alder på fuglen. Foto: Ole Friis Larsen/GFU
Torsdag eftermiddag og aften trak adskillige tusinde Mørkbugede Knortegæs (Branta bernicla bernicla) ved Hyllekrog på Lolland og Feddet på Sjælland. Også andre observationer tyder på, at det store træk er foregået op over Østlolland og Sydsjælland, snarere end ad havruten omkring Gedser Odde. Vi så dog nogle flokke fra fuglestationen først på aftenen. Trækket fortsatte fredag morgen, men i langt mere beskedent omfang. Vi fik dog en flig af trækket og talte 168 i de fem standardtimer, samtidig med at der blev talt 1.350 ved Feddet, hvilket stadig tydede på et hovedtræk nord om Falster. Knortegæssene hører til de sidste der trækker nordover; de yngler allernordligst i Sibirien, hvor foråret også kommer sidst.

En af deltagerne i torsdagens store træk var en Mørkbuget Knortegås med GPS-sender. Den har tilbragt en stor del af vinteren på den nordlige del af øen Föhr og havet i den tyske del af Vadehavet. Det sidste signal derfra kom fra GPS-senderen lige før midnat onsdag 22. maj. Torsdag 23. maj kom der et signal fra gåsen klokken 11.38 lidt nordvest for Flensburg. Derefter fulgte et signal klokken 17.37 over havet 10 kilometer syd for Rødvig på Stevns, og så fredag morgen klokken 5.37 ved Fotevik lidt nordøst for Falsterbo. Der har den formentlig tilbragt natten sammen med den flok, som den tilsyneladende er passeret hen over Langeland, måske Lolland og Sydsjælland med. Det seneste signal viste, at gåsen fredag ved middagstid var nået til Karlskrona efter en afstikker mod nord til et område med søer nord for Ängelholm.
Vejret var smukt med næsten ingen vind, men en del dis over havet. Der var godt selskab af folk, som ville se træk og havde forventninger om lidt mere rovfugletræk, end vi faktisk så. Smukt var det med to Røde Glenter (Milvus milvus), der passerede tæt over os. Også en adult/voksen Havørn (Haliaeetus albicilla) fløj lavt over os og direkte ud over havet mod syd. Havørne trækker ikke rigtig i vores del af verden, men strejfer en del omkring. Det gælder også adulte singler, som denne ørn formodentlig var.
Voksen/adult Havørn over Gedser Odde fredag formiddag havde meget lyst hoved og hals. Det er ikke ualmindeligt, at Havørne ligner deres amerikanske slægtning Hvidhovedet Havørn (Haliaeetus leucocephalos) - især i stærkt solskin. Foto: Ole Friis Larsen/GFU

Rain, but before rain some nice birds
The ringing:
Today there was definitely an improvement in the morning, it was loud with singing birds in the garden when we went on the first round. And we got some nice species: A new Rosefinch “Karmindompap”, the first Spottet Flycatcher “Grå Fluesnapper” for this season in Gedser and a Reed Warbler “Rørsanger”, we also got one in the second round and in total, we just got four of this species by now in the spring season.
Common Rosefinch "Karmindompap"
Spottet Flycatcher "Grå Fluesnapper"
Robert also took two birds out of the net, which we had seen every day, but never had in the nets so far. First I had to think a bit, but then I got what it was before the birds were out of the bags: It was two Starlings "Stær"!
Starling "Stær"
Unfortunately, there was a lot of rain on the radar and when we felt the first drops when we came out of the lab after the second round, we decided to close the nets. First the rain was just very light, but then it became heavy so many moths, data entry and data checking kept us busy for the rest of the morning and afternoon. Still we got 12 new birds in the nets in just three rounds, which is better than the numbers we had in 5 hours in the last couple of mornings.
After we had this weather change now, with quite a lot of rain and also the wind turning, our expectations are a bit higher for tomorrow. Maybe as many birds as we have had moth today? That would be great! And there are still birds on their way as we see with the Spottet Flycatcher “Grå Fluesnapper”!
Moths: The night was evidently good for moths to fly around. We caught in total 21 species of which 11 were new for the season at this location (bold in the table below). Some of the species were very small (3 to 5 mm) like the Hundegræsmøl and Mompha subbistrigella. It is difficult to make nice pictures of these small ones, because they are not sitting still as most of the bigger ones. That is the reason that I have chosen not to present these pictures, but have taken the Halmugle and the Udelt mesingugle as the species of the day.
Halmugle (Mithimna pallens)
Udelt messingugle (Diachrysia stenechrysis)
Trækket på Odden: En af de få fordele ved at stå på Nordens sydligste punkt i fem standardtimer med silende regn er, at der ikke skal bruges meget arbejdstid på at indtaste dagens resultater i DOFbasen og at skrive dagbogen/bloggen. Nå ja, men på en eller anden måde er det også godt for ens egen og for vores fælles viden at opleve, hvordan trækket tager til og af hen over året og fra dag til dag.
Regnen tog meget af udsynet torsdag morgen; sigtbarheden faldt med den tiltagende regn helt ned til nogle få hundrede meter, og det var nødvendigt at stå i tørvejr stort set hele perioden under taget på den gamle marinestation, som heldigvis er der endnu.
Alligevel var der en overraskelse, som der af og til netop er i vådt vejr. Lige før tællingen sluttede dukkede en stor flok fugle frem af regndisen som grålige silhuetter, der med rolige vingeslag hurtigt forsvandt igen i disen mod nordvest – en usædvanlig trækretning. De lignede umiddelbart en flok Hjejler, som vi er vant til at have her om efteråret og vinteren, men de havde lange tynde næb, som buede opad, og derfor kan det kun have været en stor flok Små Kobbersnepper.
Nogle få kald fra den mindst 350 fugle store flok lignede heller ikke Hjejlers kald, men passede i hvert fald bedre med kaldet af Lille Kobbersneppe på mobiltelefonens Fugle i Felten-app. Der foregår ofte store træk så højt oppe, at vi ikke kan se fuglene. Det gælder også vadefugle, og flokken af Små Kobbersnepper har måske søgt nedad i regnskyerne; det kan også forklare den lidt mystiske trækretning - måske mod Rødsand.

Rose finch day
Ringmærkningen
Two birds in the first round – that is unfortunately not so uncommon this spring. And so our hopes were not too high for this morning, also because the wind was blowing quite a bit. As there are so few birds, we are swapping rounds. Robert had the luck on his side on his rounds today. In the third round, he took out a single bird, which was a Common Rosefinch “Karmindompap”.

And in the round before the closing round, he took out the second! This one I got to ring so we both had one and also Ole came to see the second. I was actually some nice species in the nets, also a Red-backed Shrike “Rødrygget Tornskade” and a Goldfinch “Stillits”, but again a bit too few…

For tomorrow, there is rain on the weather forecast, so we are not sure if we can actually ring and for how long, but if it will be possible, Hans said, it might be good, so let´s see, what tomorrow brings…
Moths
There was more wind in the night, which is normally not resulting in many moths in the trap, but we still had 8 species (16 moths). One was new: in Danish it is called the Tidselfladmøl and in English the Brindeld Flat-body (see picture), one of the smaller moths. It can be found in most parts of Denmark.

Trækket på Odden: Østenvinden fortsatte onsdag, lidt hårdere; der var skum på bølgerne og efterhånden en del havgus, som gav stadig kortere udsyn. Trækket af hanner fortsatte blandt Ederfuglene (Somateria mollissima) med et tiltagende, men stadig lavt antal. Blandt dagens 91 udelukkende adulte/voksne hanner var to hunner.
Et andet træk så også ud til at være i vækst med 78 Knopsvaner (Cygnus olor) mod vest. Det lignede et fældningstræk mod områder med rigelig mad til en periode, hvor de ikke kan flyve, og selv om de var hvide, var det nok mest yngre svaner, som ikke er ynglefugle endnu.
Desuden var der lidt Sortstrubede og Rødstrubede Lommer (Gavia arctica, Gavia immer) både mod sydvest og mod nordøst.
Fra havet kom en Hvepsevåge (Pernis apivorus) ind over land. Det var lidt overraskende i den hårde vind, men den kom også østfra og har måske i virkeligheden været på vej mod Sverige.

Nyt fra stationen: Onsdag fik vi også klippet græsplænen og stierne over engen, da John dukkede op for at se, om græsset trængte til at blive gjort lidt kortere. Pasningen af haven og engen er en vigtig forudsætning for, at vi kan ringmærke, tælle træk og i det hele taget bruge fuglestationen. Det er dejligt, at vi også har frivillige, som vil påtage sig den slags arbejde.
