Latest bird photos
	5094 (3 photos) Red Kite (Milvus milvus ) Rød Glente ~ Röd Glada 2023-03-22 Vinkelhuse (Tårnby), Denmark Adult. You go by the lanky silhouette and learn that when the tail is spread like this and the cleft is gone, it is still a Red Kite.
	5093 (1 photos) Mandarin Duck (Aix galericulata ) Same bird: 2 Mandarinand ~ Pato Mandarín ~ Mandarinand 2023-03-21 Tømmerupvej (Tårnby), Denmark Female. Ullerup branddam.
	5092 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Same bird: 6 Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-21 Dragør Havn, Denmark Adult. Banded with black text on white on right leg: 1RW. Metal band on left leg. Banded Black-headed Gull
	5091 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Same bird: 8 Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-21 Dragør Havn, Denmark Adult. Banded with black text on white on right leg: 1SB. Metal band on left leg. Banded Black-headed Gull
	5090 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Same bird: 32 Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-21 Dragør Havn, Denmark Adult. Banded with black text on white on right leg: 3LZ. Metal band on left leg. Banded Black-headed Gull
	5089 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Same bird: 57 Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-21 Dragør Havn, Denmark Adult. Banded with black text on white on right leg: 8RV. Metal band on left leg. Banded Black-headed Gull
	5088 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Same bird: 43 Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-21 Dragør Havn, Denmark Adult. Banded with black text on white on right leg: OSU. Metal band on left leg. Banded Black-headed Gull
	5087 (2 photos) Tundra Swan (Cygnus columbianus ) Pibesvane ~ Cisne de Tundra ~ Mindre Sångsvan 2023-03-20 Kalvebod Fælled, Denmark Villahøj. 20 ad and 4 young. Bad weather made the extensive wet flats attractive for a quick roost before continuing north.
	5086 (1 photos) Tawny Owl (Strix aluco ) Same bird: 28 Natugle ~ Cárabo Común ~ Kattuggla 2022-03-12 Kongelundsområdet, Denmark Male and female.
	5085 (6 photos) European Stonechat (Saxicola rubicola ) Sortstrubet Bynkefugl ~ Tarabillo Europeo ~ Svarthakad Buskskvätta 2023-03-19 Kongelundsområdet, Denmark Second calendar year. Female. Kongelundsengen. Two fresh tertials and greater arm coverts suggest that this is a young bird. This bird looks rather pale for the species, or perhaps it is because I normally don't see females this early in the year and the pale feather fringes only have been worn off to a minor degree. At first I thought it might be a Siberian, but the upper tail is conclusive, and over all a Siberian would probably be even paler at this date.
	5084 (1 photos) Mandarin Duck (Aix galericulata ) Same bird: 2 Mandarinand ~ Pato Mandarín ~ Mandarinand 2022-11-08 Tømmerupvej (Tårnby), Denmark Female. Ullerup branddam. Last year it left around the 16th of March. Maybe the cold weather makes it hesitate..?
	5082 (1 photos) Gray Heron (Ardea cinerea ) Fiskehejre ~ Garza Real ~ Gråhäger 2023-03-17 Frederiksberg Have, Denmark Adult. Nest supplies.
	5081 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-17 Frederiksberg Have, Denmark Adult. Banded with black text on white on right leg: 5UV. Metal band on left leg. Banded Black-headed Gull
	5080 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-17 Frederiksberg Have, Denmark Adult. Banded with black text on white on right leg: OVH. Metal band on left leg. Banded Black-headed Gull
	5079 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-17 Frederiksberg Have, Denmark Adult. Banded with black text on white on right leg: OVJ. Metal band on left leg. Banded Black-headed Gull
	5078 (1 photos) Black-headed Gull (Chroicocephalus ridibundus ) Hættemåge ~ Gaviota Encapuchada ~ Skrattmås 2023-03-17 Frederiksberg Have, Denmark Adult. Banded with black text on white on right leg: S40. Metal band on left leg. Banded Black-headed Gull
	5077 (3 photos) (1 sounds) Canada Goose (Branta canadensis ) Canadagås ~ Ganso Canadiense Mayor ~ Kanadagås 2023-03-17 Frederiksberg Have, Denmark Adult. Male. Assuming the noisy bird is a male dominating the smaller female Graylag Goose. At least they moved about together why I assume it's a pair. And probably the parents to the 3 hybrids here, 5076. Sound file, also: Hooded Crow, Eurasian Blue Tit, Mallard.
	5076 (9 photos) (1 sounds) Graylag x Canada Goose (hybrid) (Anser anser x Branta canadensis ) Grågås x Canadagås (hybrid) ~ Ganso Común x Canadiense Mayor (híbrido) ~ Grågås x Kanadagås (hybrid) 2023-03-17 Frederiksberg Have, Denmark 3 different birds. Likely offspring of the same pair, that was also present in the park. See 5077. If they are siblings, its surprising to see how different they look. The call is from Bird 3 (also: jogger, Eurasian Blue Tit, Hooded Crow). Compared to 5077 it has a more Graylag shrilling quality to it. Bird 1: photo 1-3 Bird 2: photo 4-7 Bird 3: photo 8-9
	5075 (4 photos) (1 videos) Pink-footed Goose (Anser brachyrhynchus ) Kortnæbbet Gås ~ Ganso Piquicorto ~ Spetsbergsgås 2023-03-17 Frederiksberg Have, Denmark Adult. A single bird has been present for some time. Being a city park, a suspicious origin is the most likely. However, it is a fact that the species has started to migrate through the eastern part of Denmark to a larger extend during recent years. The probable logic behind this is, that the species has started to breed on the arctic Russian island Noveja Zemlja, a thousand kilometers east of the Svalbard population. The bird looks healthy and apparently has been seen elsewhere in Copenhagen, why its ability to fly and move is good, and in all respects the bird looks like a classic representative of the species.
	5074 (1 photos) Common Kingfisher (Alcedo atthis ) Isfugl ~ Martín Pescador Común ~ Kungsfiskare 2023-03-15 Kalvebod Fælled, Denmark Adult. Female. The channel just north of Finderuplågen. It's been here for a while during winter, but the first time I see it.
	5073 (1 photos) Mandarin Duck (Aix galericulata ) Same bird: 2 Mandarinand ~ Pato Mandarín ~ Mandarinand 2023-03-15 Tømmerupvej (Tårnby), Denmark Female. Ullerup branddam. Still present. Last year I saw it the last time for the season on March 16. But it is probably colder this year, which might cause a delayed desire to move on.
	5072 (4 photos) Black Guillemot (Cepphus grylle ) Tejst ~ Arao Aliblanco ~ Tobisgrissla 2023-03-12 Prøvestenen (syd), Denmark Second calendar year. Assuming it's the same one bird that has decided to spend the winter here.

Metal band on left leg. The tail coverts herring like, but the tail pattern with narrow black and white bars next to the broad dark tail band is good for Caspian. Banded, Uncertain
	5044 (2 photos) Great Cormorant (Phalacrocorax carbo ) Skarv ~ Cormorán Grande ~ Storskarv 2023-03-10 Christianshavns vold og voldgrav, Denmark Third calendar year. A young adult with few white neck plumes. The darkish bill must be an indication of a bird growing older, though it is not mentioned as an aging criteria, where I've looked. I think the sport in Denmark regarding this species is to separate the two subspecies carbo and sinensis. It has been my perception, unqualified?, that most birds were continental sinensis but it appears that the larger part of photos on netfugl.dk have ids to subspecies level and the majority are N Atlantic coastal carbo. How is that possible when the most reliable field mark is the angle of the gular pouch below the eye, and there is an overlap zone where subspecies cannot be determined by this criteria alone. According to studies, birds with an angle of 65 degrees or less are surely carbo and birds showing 73 degrees or more are confirmed sinensis. This gives you an 8 degrees span to base your field-photo decision on. Absolutely unreliable if you ask me. Assuming that many, perhaps depending on which birding generation you belong to, are defaulting their observations to subspecies level without solid support. Using an online measure device I get the angle on this bird fall in overlap or sinensis zone, depending on how I make the measuring. And a correct measurement of course should be made on a bird that has the head completely in the neutral planes perpendicular to the observer.
