Brant (Branta bernicla) ebird/Clements (2022)
	2364 (11 photos) Brant (Branta bernicla bernicla) Knortegås ~ Ganso de Collar ~ Prutgås 2016-11-13 Dragør Kommune, Denmark Family flock - 2 adults and 4 young birds. The age field marks are very clear here: Adults with the heavy neck patch, whitish vertical lines toward the flank and uniformly colored gray wing coverts. The only birds I saw this year. Apparently a late family stopping over for a while to forage before heading further on toward the Channel region. Dark-bellied because of the dark belly and flank, and dark between the legs. The only type of Brant regularly seen in the eastern part of Denmark.

Dark-bellied bernicla is the common subspecies in this part of Denmark. Light-bellied hrota normally only seen in Jutland, and even though the distance is as little as a few hundred kilometers, this separation is a very consistent habit. A few hundred birds were roosting this day.
	3213 (3 photos) Brant (Branta bernicla bernicla) Knortegås ~ Ganso de Collar ~ Prutgås 2019-11-01 Amager Strandpark, Denmark Young bird with white tips to wing coverts and back feathers plus no white neck patch. Also the uniformly dark belly and flanks without indication of vertical streaking is an age mark. 4 or 5 were lying on the water and this one joined them when yet another notoriously ignorant dog owner chased off the bird.

	3638 (2 photos) Brant (Branta bernicla bernicla) Knortegås ~ Ganso de Collar ~ Prutgås 2021-10-31 Kalvebod Fælled, Denmark Adult. Aged by lack of whitish edges to the coverts. I'm not sure if the different nuances of the coverts is a simple reflection of worn vs. new adult feathers or if it indicates that it is young adult, 2cy bird. The weak necklace could indicate the latter. A privilege, every year, to have few of these birds visiting and allowing one to come this close.
