Close your Mouth and Open your Eyes

torsdag 31. oktober 2024
af Lara Winsloe & Susanne Primdahl

Ringmærkningen: Det har været en vild dag – ikke så meget på grund af fuglene, men vinden var ret vild, så vi måtte lade en hel del af nettene være lukkede.
Vi måtte stille os til takke med 4 ringmærkede fugle. Dertil en enkelt aflæsning af en gammel kending i haven. Den aflæste Fuglekonge blev nemlig ringmærket den 25. oktober og er siden blevet aflæst 4 gange.

Migration at Gedser Odde

by Lara W

3,193 individuals of 38 species were counted on migration today. A steady flow of Common Eider/Ederfugl (Somateria mollissima) passed throughout standard time this morning, with 1,393 counted. 580 of these were identified as Female/Juvenile/Hun-farvet, compared to 285 Males, a much better ratio considering the male-dominated migration up until recently. Red-breasted Merganser/ Toppet Skallesluger (Mergus serrator) came by in much higher numbers than previously, totalling 344 migrating south, mostly in groups of 3-4 but occasionally in larger flocks of up to 16. Their flight pattern is patently recognisable – the long neck and rapidly-fluttering wings with their obvious white wing bar making identification easy. I was happy to spot a single Goosander/Stor Skallesluger (Mergus merganser), a cousin to the Red-breasted Merganser, later on in the morning, with its pale creamy-yellow neck and strongly demarcated dark head. A very smart bird!

Goldeneye/Hvinand and Long-tailed Duck/Havlit are gradually becoming more numerous, with 63 and 11 counted respectively. 37 Red-throated Diver/Rødstrubet Lom were spotted too, often flying past in twos and threes. Observing this genus fly always affords me an internal chuckle (alright, a slightly mean-spirited snigger, I will admit): on the water, divers are stunningly elegant, their sinuous and slender necks poised in an attitude of permanent grace, their plumage perfectly coiffed. In the air, however, they morph into hump-backed, awkward-looking, ill-proportioned, and simply weird-in-general creatures. There is a balance in most things is the moral here, it seems.

Many birds came close to shore as they passed south today, in numbers that enabled me to view them properly, allowing appreciation for the many forms, and colours, and movement, that the long process of evolution has created. Number- and rarity-chasing are hobbies for some, but sometimes it is just as special to sit and watch nature as it is: fluid, vivid, transient, built to stand the test of time and the pressures of the world through the constant and consistent transmogrification from one form to another. Our presence, as a species, on this planet, is a miracle in itself, despite the negative effects we have on the environment, but one thing is for sure: nothing we do will stop nature. It will continue on without us when we are long gone, all we can do now is appreciate it in all its splendour, and try to protect it.

Take a breath, pause, and look out the window. What can you see that does not demand admiration? We are surrounded by beauty, you really don’t have to look far to see it.

Fugle og en Svamp

onsdag 30. oktober 2024
af Larissa Britton

Ringmærkningen: A total of 34 new birds today, with a couple of Redwing/Vindrossel (pictured below) and a cute female Bullfinch/Dompap comprising my personal highlights. On the closing round, I noticed some Candlesnuff Fungus/Slank Stødsvamp (Xylaria hypoxylon) peeking through the bed of moss below one of the nets. A spooky looking fungi with a well-suited name, I feel.
Tomorrow, it is Halloween, and we hope that there are some more treats in store for us. Traditionally, the 31st of October marks the beginning of Samhain celebrations. Samhain, meaning "November" in the Irish language, is a Gaelic festival on the 1st of November that notes the beginning of Winter.

Dråbefangerne på arbejde

tirsdag 29. oktober 2024
af Lara Winsloe & Susanne Primdahl

Ringmærkningen: Med en let regn i morges var det simpelthen for vådt til, at vi kunne tillade os at fange de små Fuglekonger, så vi åbnede nettene 45 minutter senere end planlagt. Det var stadig så vådt i starten, at vi kunne ryste en hel del vand af nettene, selvom vi kun havde et kvarter mellem hver runde.

Efter hvert kvarter var nettene fyldt med vanddråber, så med det meget lille antal fugle følte vi os mere som dråbefangere end fuglefangere. Lidt blev der dog for Jakob og Birgit at øve sig på.

IMG 7961 red
Dagens talrigeste fugl var endnu en gang Fuglekongen. Her er det en ung han fra i år, selvom man ikke kan se noget orange i striben på hovedet. Det ses først, når han rejser issefjerene lidt, så for at kønsbestemme Fuglekongerne i forbindelse med ringmærkning purrer vi lidt op i issefjerene for at se, om der kun er gule fjer, eller om der gemmer sig nogle orange fjer i skjul af de gule.   Foto: Susanne Primdahl

Træktællingen:

by Lara W

Despite hopes for another strong thrush migration, heavy fog obscured much of the land and sea around the point this morning. Total birds counted migrating was 1,176 of 23 species, not a huge number, but enough to keep us just about occupied throughout standard time. The fog drove a good amount of birds much closer to the coast though, so we were granted good views of Goldeneye/Hvinand (Bucephala clangula), Long-tailed Duck/Havlit (Clangula hyemalis) and two small flocks of Dunlin/Almindelig Ryle (Calidris alpina) as they flew past. A couple of Black-throated Diver/Sortstrubet Lom (Gavia arctica) were spotted foraging near some resting Common Eider/Ederfugl (Somateria mollissima), and I watched with some amusement as a female Eider chomped down on (what I presume to be) a mussel/musling that seemed far too big for her for several minutes.

Our Kestrel/Tårnfalk (Falco tinnunculus) friend kept us company for most of the morning, perching under the rafters of the old building out on the point to hide from the drizzle, and occasionally fluttering down to snatch up an earthworm – often within about 2m of where I was standing. Ole managed to capture a few photos of her, in an attempt to read the metal ring she had on her right leg. A couple of digits were legible, and we realised the ring was from Stockholm! A message has been sent to the ringing group there, in the hopes that we can obtain some information on the bird, watch this space for updates!

The Thrushes are Here

mandag 28. oktober 2024
af Larissa Britton & Lara Winsloe

Ringmærkningen: Today, a grand total of... 10 birds! Plus 5 recaptures. Vindrossel/Redwing (Turdus iliacus) teased us today, with a flock flitting through the garden's berry-laden bushes, but just missing our mist nets. We did have two gorgeous male Bogfinke/Chaffinch (Fringilla coelebs) today - one 1K bird and one 2K+ bird. This lead to an educational comparison, with the moult contrast distinctly present in the wing of the 1K bird, and the adult not showing this contrast but instead possessing uniform plumage. It was nice to visualise the differences when ageing this species. I really enjoy handling Chaffinches, as they have a special place in my heart.

Trækket på Odden: 

by Lara W

A total of 7,109 birds of 52 species were counted on migration this morning. The morning started with reports from Gedser of large flocks of thrushes passing over the town, so we were hopeful of spotting at least several hundred of these birds migrating past the point. We were not disappointed! Mistle Thrush/Misteldrossel, Redwing/Vindrossel, Fieldfare/Sjagger, and Song Thrush/Sangdrossel were all seen on migration, with a total of 1,337 individuals counted, in both single and mixed-species flocks. Passerine and near-passerine migration in general was good for at least a couple hours of standard time, with 20 species seen, the most abundant of which were Chaffinch/Bogfinke and Brambling/Kvækefinke at 1,235 birds. Several medium-sized flocks of Twite/Bjergirisk were spotted much to our delight, with 63 individuals counted, up by several orders of magnitude from previous days. In addition, 825 Siskin/Grønsisken, 281 Linnet/Tornirisk, and a single late Barn Swallow/Landsvale were counted, among others. Thanks to Benjamin Lisse for keeping his eyes and ears peeled for all the small peep-peeps, as well as doing his level-best to teach me how to identify birds by their flight patterns, grouping, and general movement. I would like to take this opportunity to thank Ben for being a fantastic teacher, birder, and good companion throughout the long hours on the point. If you are reading this Ben, thank you, and good luck with your upcoming university exams!

Raptor migration was much slower than earlier on in the week, with just 19 Sparrowhawk/Spurvehøg and a single Rough-Legged Buzzard/Fjeldvåge making the crossing, although a couple of buzzards were seen hunting around the Fuglestation throughout the course of the morning. The Kestrel/Tårnfalk which has been hunting in the area around the point over much of the last week continued to keep us company, often coming down to earth within 15m of our position. The delicate features and colouring of this bird have always given me pause, the tear-shaped markings, reminiscent of a Cheetah/Gepard, running down from the inner eye corner on either side of the bill; the bill itself – sharply curved, and much more petite than the similar-sized Sparrowhawk’s; the warm reds and browns of the upperparts, paler belly and pantaloons (yes, they are pantaloons, do not try to convince me otherwise!) with their delicate barring, and deep browns and blacks of the primaries all combine to make a truly beautiful looking bird.

The large flocks of Barnacle Goose/Bramgås which are currently taking up residence in the area periodically swept above our heads, venturing a little out to sea before returning inland. We counted 50 of these embarking on migration, although several other geese were also noted flying south: 35 White-fronted Goose/Blisgås, 4 Tundra Bean Goose/Sædgås ssp.rossicus, and 6 Dark-bellied Brent Goose/Knortegås ssp.bernicla. Action on the sea was mainly confined to a couple of hours around the midway point of standard, with 2,318 Common Eider/Ederfugl, 176 Common Scoter/Sortand, and 86 Red-breasted Merganser/Toppet Skallesluger making up the majority. The last few Sandwich Tern/Splitterne appear to be passing, with 4 recorded, although gull migration appears to be picking up in volume, with 29 Common Gull/Stormmåge, 8 Herring Gull/Sølvmåge, 6 Black-headed Gull/Hættemåge, and 7 Little Gull/Dværgmåge recorded. 24 Red-throated Diver/Rødstrubet Lom, 5 Red-necked Grebe/Gråstrubbet Lappedykker, 10 Long-tailed Duck/Havlit and a surprising 13 Razorbill/Alk were also counted, although the appearance on the scene of two adult Gannet/Sule provoked particular interest. One individual remained within sight foraging, for a good half hour, gliding around 25m above the waves before abruptly folding in his wings to plunge downwards like a stone – crashing almost vertically through the waves to emerge, occasionally up to 30 seconds later, with a dramatic breaking of the dark waters around his shockingly white body. Being such a large bird, he was easily visible with the naked eye even several hundred metres out – a real pleasure to witness in his natural environment simply behaving like the wild creature he is.

Få fugle og mange ringmærkere

søndag 27. oktober 2024
af Susanne Primdahl

Fuglemæssigt var det en stille dag med blot 16 ringmærkninger, men til gengæld var vi flere ringmærkere end sædvanligt. Der var nemlig hele 3 ret nye X-mærkere med på holdet i dag. En X-licens er den første licens, man får tildelt, når man starter som ringmærker.

Hvis vi tæller Hans med, som lige hjalp med et par fugle ved den ene X-mærker, var der hele 6 ringmærkere i gang i dag, så der var rigtig god tid til at snakke om håndtering og bestemmelse af fuglene.

Og så håber vi, at Anne fanger en ugle eller to i aften til at pynte på dagens ringmærkningsresultat.

Sparrowhawk in the garden

Ringing:

by Lara W

65 birds of 12 species were ringed today, with Goldcrest/Fuglekonge making up the majority at 40 individuals. Several thrushes came through too: 1 Blackbird/Solsort, 2 Song Thrush/Sangdrossel, and 3 Redwing/Vindrossel. 

Udklip_2024.10.26.JPG

I had a lovely second calendar year (2K) male Sparrowhawk/Spurvehøg around midmorning, who as you can see from the photograph below, was almost completely slate-grey on the upperparts aside from a touch of rufous fringing to the lesser coverts along the scapulars, and a couple of brownish feathers over the rump. We also had a recaptured Sparrowhawk, the same male we ringed a couple of days ago, who is clearly still hunting around the station area before embarking on migration.

Dagens billedbog

fredag 25. oktober 2024
af Susanne Primdahl

Ovenpå gårsdagens altomsluttende tåge var det skønt med en flot solskinsdag, og lunt var det også på grund af den svage vind. Der var ikke det store rykind af fugle, men helt tomt var det heldigvis ikke.

Vi ringmærkede 45 fugle, og det var de mindste ringe, der var brug for. Det var nemlig Gransangerne og Fuglekongerne, som tilsammen udgjorde over halvdelen af dagens ringmærkninger. Især Gransangerne var godt rustet til det fortsatte træk med fedtscorer over middel.

Der blev fanget yderligere 7 arter, hvoraf nogle fremgår af de følgende billeder.

The Fog

torsdag 24. oktober 2024
af Larissa Britton & Lara Winsloe
Ringmærkningen: 
 
by Lara W

Our morning started out with a fair few Wren/Gærdesmutte (Troglodytes troglodytes) and Goldcrest/Fuglekonge (Regulus regulus), both new birds and recaptures, showing that the station garden, with all its fruit trees, to be of significance to birds stocking up for the oncoming winter and as a migratory pit-stop. Fat scores are taken for all the birds caught, providing insight into how useful the site is for foraging. Much to my delight, a single Blue tit/Blåmejse (Cyanistes caeruleus) was caught, his rather chunky blue feet latching on to my fingers as I extracted him from the net, the better to gain the required leverage for a furious onslaught of pecking. Such a gorgeous little monster!

20241024_100826.jpg

Catches slowed towards midmorning, as fog crept in from the sea (see Larissa’s beautifully evocative photos below), settling over the garden, muffling the peeps and trills of the birdlife, until all was peacefully still. The resident Kestrel/Tårnfalk (Falco tinnunculus) who often hunts in the meadow beyond the garden, returned several times to perch high up on the metal antenna throughout the morning, backlit by the pinkish dawn sky and, later, her silhouette an ideographic smudge of dark just visible through the fog.

Several Great tit/Musvit (Parus major) flew into the nets too, all male, with their striking mantles of forest green contrasted sharply against deep lemon-yellow underparts and inky blue-black head feathers. Birds at this time of year always appear so much more vibrant in their post-breeding plumage, the crisp autumnal air and diluted tones of the sun perhaps adding a certain edge to their ornamentation.

On the closing round, I was greeted by a juvenile male Sparrowhawk/Spurvehøg (Accipter nisus), glaring upside-down at me with a bewildered yet fierce expression in his pale yellow eyes (the iris of older birds becomes more and more orange). A young bird, from his overall chestnut colouring and heart-shaped markings on the breast feathers, and clearly a male from his small and dainty stature. I have been reading Ian Newton’s The Sparrowhawk (London, 1986), an interest sparked by the many titular birds migrating across Gedser Odde of late, and it seemed especially poignant to be granted the opportunity to study an individual up close. Delicately formed, his long legs ended in sharp, strongly curved talons, designed for puncturing - as my finger gratefully experienced- the pupil constantly dilating and constricting as he took in myself and his surrounds, a reflex denoting this species position as a visual predator. Sparrowhawks predominantly eat birds, with the much smaller males taking prey items of around 5-80g, which goes quite a way to explain the extremely disturbed Goldcrest I found in the net not a metre from the small raptor. Females on the other hand, being of a larger size, prey upon birds of around 20-120g, and are known to also take Woodpigeon/Ringdue (Columba palumbus, a fascinating name to speak aloud!). It is due to this diet that Sparrowhawks migrate south in autumn, as they follow their smaller passerine prey south for the winter. Most of the Sparrowhawks passing us here in Gedser will end up around Spain or thereabouts.

Calm conditions today, with low cloud and slight haze at dawn serving as a taster of the fog that would reduce our visibility throughout the count. 915 birds were counted today despite the (sometimes) very poor visibility, representing 29 species.

Early in the count, we saw three Long-tailed duck/Havlit (Clangula hyemalis) - it is really exciting to see these arriving. Later in the morning, the fog closed in. After patiently waiting for the fog to lift, emerging from the mist, two Guillemots appeared - one Black/Tejst (Cepphus grylle) and one Common/Lomvie (Uria aalge). Soon after this, a group of three Red-necked Grebe/Gråstrubet Lappedykker (Podiceps grisegena) followed. 12 Red-throated Diver/Rødstrubet Lom (Gavia stellata) and two Black-Throated Diver/Sortstrubet Lom (Gavia arctica) were also counted in the intervals of good visibility. The fog closed in on us once more and, this time, would stay for the remaining duration of the count. Today's foggy interludes were spent chatting, keeping an ear out for any birds flying overhead concealed in the fog, and munching on 'local' (a.k.a, from Denmark) pears - tak, Louis!

Beautiful challenges

onsdag 23. oktober 2024
af Roger Dickey & Ole Friis Larsen

Ringmærkningen: As a guest ringer, only spending six days here, I was not expecting to describe our ringing exploits here as it will take me at least that time to work out protocols and ring sizes, and without understanding a word of Danish. So it was a bit of a surprise to be asked to write a blog on the wettest day of the visit – the offer declined until today when the sun emerged at dawn and the wind dropped to allow us to continue our capture of Goldcrests (Fuglekonger) and Wrens (Gærdesmutte) in good numbers. These were interspersed with Firecrests (Rødtoppet Fuglekonge), a bird rarely seen in the UK but seemingly not uncommon here. But back to the Wrens which are moving in family groups of one or two adults with up to four youngsters. It’s a novelty to see what is usually a sedentary bird moving in migration. This is unlike the extraordinary number of Goldcrest which we know move across seas in the spring and autumn but demand respect that such a small bird of only a few grams can fly such long distances.

So far, the scene is set for a routine morning’s ringing but just to keep us on our toes, a Short-toed Treecreeper (Korttået Træløber) was caught. Not that difficult to tell from my usual Common Treecreeper (Træløber), as the long, curved bill, seen in the photo, is the most obvious and striking feature. There are several other distinguishing features between the species but most are small in detail and best left to the black-art practised by ringers.

When ringing in a different country or environment, it is rather nice to come across old friends, in this case, Chiffchaffs (Gransanger), a solitary House Sparrow (Gråspurv), and a young female Bullfinch (Dompap). Soon after having her ring checked, the sparrow retired to a nearby tree and expressed her lack of amusement with a long tirade of alarm calls.

And with all these small birds about and with so many Eurasian Sparrowhawk (Spurvehøg) flying overhead, it was almost inevitable that one would chance its luck but become caught in one of our nets. A cold glare from this yellow-eyed raptor makes one almost sorry for any unfortunate potential prey. Ours today was a young female, looking so much larger than the males, and probably an inexperienced hunter, hence becoming trapped in our net.

Trækket på Odden: Dagens største udfordring på landets sydligste punkt kom aldrig tæt nok på til at blive set ordentligt, men den trak heller ikke ud, så måske er vi heldige at se rovfuglen igen. Det var en Rørhøg (Circus aeroginosus), som så ud til at have nogle interessante lyse tegninger på undersiden af vingerne, en såkaldt hun-farvet brun fugl. Fugle, som ser anderledes ud, end vi forventer er altid spændende; det kan være usædvanlige mønstre eller tegninger inden for rammerne af den normale variation hos mange arter, men det kan også være sjældne repræsentanter for andre bestande, hybrider af to arter, underarter eller ligefrem arter end dem, vi er vant til at se i den daglige trafik af fugle.

Standardtiden bød ellers på et varieret udvalg af 47 arter uden nogen imponerende antal, med et samlet resultat på 6.000 fugle, hvoraf halvdelen var Ringduer (Columba palumbus) – svenske, finske og russiske fugle på vej til overvintring i Vesteuropa.

Skaermbillede 2024 10 23 174507Onsdag bød på to udtrækkende Musvåger (Buteo buteo). Statistikken viser med røde søjler, at trækket af Musvåger er kommet godt i gang i anden halvdel af oktober efter længe at have været svagere end normalt (kurven). Trækket tegner lige nu også til at blive større end sidste år, da det også foregik i sidste halvdel af oktober. Grafikken viser intensiteten i trækket som fugle per time i vores standardtid. Kilde: Trektellen.

GFU okt onsd 2194En af Musvågerne i efterårstrækket ved Gedser Odde sidste år var denne meget lyse variant - bemærk de mørke øjne, som er karakteristiske for adulte/voksne Musvåger og her er særlig tydelige. En af gevinsterne ved at arbejde meget med trækket er oplevelsen af de store variationer, der forekommer hos mange arter. Arkivfoto: Ole Friis Larsen/GFU

Det meste havtræk så ud til at foregå langt ude over havet, hvor vi akkurat kunne ane uskarpe mørke prikker af andefugle flimre i disen og modlyset. Sådan et træk kan vi ikke forholde os til med usikre antal, der for de flestes vedkommende er umulige at bestemme. Standarden ved Gedser Odde siger – som mange andre steder – at vi skal tælle de fugle, vi kan se i håndkikkert og kun bruge teleskopet til hjælp til at bestemme de fugle. Det kan ingen helt overholde, men det er en tommelfingerregel om ikke at bruge tid på de allerfjerneste fugle.

Fra land kom der lidt mere gang i trækket af Spurvehøge (Accipiter nisus). To adulte/voksne hanner af Blå Kærhøg (Circus cyaneus) vakte også opsigt, og flere fik tid til at øve sig på at bestemme småfugle. Ofte er det ikke muligt at bruge detaljer i fjerdragten til identifikation, men så kan vi arbejde med flokkenes størrelse, bevægelsesmønstre og tæthed i kombination med fuglenes silhuet – og når der er folk med særlig god hørelse: fuglenes kald.

Skønne skandinaviske konger

Ringmærkningen: Allerede i går lignede vejrudsigten noget, der ikke ville give mulighed for en standardmærkning i dag. Der var udsigt til regn hele formiddagen, men man skal aldrig opgive håbet.
Vi fik lavet datatjek helt frem til dags dato, og derefter fik vi lige nøjagtigt åbnet nettene 5 minutter før deadline. Når det er for dårligt vejr fra morgenstunden, må vi nemlig højst forsinke åbningen med to timer.

Det støvregnede stadig, så vi åbnede kun 6 net og gik de første runder hvert kvarter for ikke at få våde fugle. Efterhånden kom solen frem og gav os det skønneste vejr, mens nettene leverede lidt fugle på næsten hver eneste runde. Og det var heldigt, at vi fik åbnet i rette tid til at tage imod to udenlandske gæster.

Først kunne Roger pille en svensk Fuglekonge ud af nettet, og allerede på næste runde fik jeg en finsk Fuglekonge, så der var glæde på ringmærkerfronten. Det er altid noget særligt, når der dukker fugle op, som er ringmærket i udlandet.

Fuglekongerne dominerede endnu en gang billedet, som det har været tilfældet i flere dage, mens Gærdesmutterne ikke gjorde så meget væsen af sig i dag. Det kan meget vel være den sene netåbning, der er årsagen til det, for Gærdesmutterne kommer næsten altid i størst antal tidligt på morgenen.

Trækket på Odden: Når vi går ud for at tælle trækfugle og indsamle data, er det altid bedst at tage ud på Odden uden forventninger om noget som helst – så bliver man ikke skuffet. Denne tirsdag startede vådt, og regnen fortsatte to en halv time ind i standardtiden. Det gav kun ganske få fugle i havtrafikken og ingen fra land. Dagens mest bemærkelsesværdige oplevelse var imidlertid, at der næsten heller ingen fugle kom, da regnen sluttede, og det oven i købet klarede op til noget solskin.

Efter en halv times sol kunne vi se en flok på 27 Musvåger (Buteo buteo) kredse over området. 14 af dem trak kort efter ud mod syd, mens resten forsvandt tilbage mod nord, men det var så nok dem, der lidt efter lidt kom sivende og bragte det samlede træk af Musvåger op på lige netop 27. Efter mandagens store træk af Spurvehøge (Accipiter nisus) troede vi, at opklaringen ville sætte gang i nogle Spurvehøge, men der kom kun tre i løbet af de to en halv time med tørvejr. Den slags oplevelser er med til at gøre det interessant at registrere fugletræk, som vi helt oplagt stadig mangler masser af viden om.

Vores beslutning om systematisk at køns- og aldersbestemme Fjeldvåger (Buteo lagopus) på træk var en særdeles overkommelig udfordring tirsdag, da der kun kom en enkelt i standardtiden, og den kom så fint tæt forbi, at den uden videre kunne bestemmes til en 1k ung Fjeldvåge fra i år.

Trækket af småfugle forblev småt, og opklaringen satte ikke skub i fugle ude over havet, snarere tvært imod. Til gengæld betød opklaringen, at vi kunne se de få, der trods alt var.
