And aslo see website: The Gulls Of Appledore. Green J01 banded in 2014 in this colony. below: American Herring Gull (smithsonianus) J01 1st cycle (1CY), August 14 2014, Appledore Island, NH. Picture: Lauren Kras.Completely juvenile plumage. Very pale bird overall. Still in fresh plumage indicated by the beige tones on the feathers. These parts will soon bleach to white leaving a contrasting patterned bird, unlike classic 1st cycle smith's. below: American Herring Gull (smithsonianus) J01 1st cycle (2CY), May 22 2015, DuPont Nature Center, Delaware Bay. Picture: Emily Weiser.Emily, who is studying waders, found this banded bird in May along the shores of Delaware Bay. The complete moult may commence any moment now, and the juvenile wing-coverts are very abraded, completely worn and bleached white. It is easy to tell which feather tracts were included in the post-juvenile moult (first pre-basic moult): there is a greyish scapular saddle and grey feathers on the flanks and belly. |
