Tony Leukering Posted August 31, 2020 Share Posted August 31, 2020 13 hours ago, HamRHead said: Agreed. Adult and juvenile or non-breeding adult. Adults nearly always have at least some spotting below. Adult in Dec First-year in Dec Note that the adult's plumage is nearly pristine, with all feathers replaced in the fall. Note that the youngster's is not, with a blob of very worn wing coverts. Finally, note that in AUGUST, the plumage states are reversed, with juvs wearing fresh, pristine juv plumage (as in the pic above) and the adults are wearing relatively worn plumage (as in the pic above). Note also the fine pale fringe to each crown feather and the relatively dull leg color on the juv. https://cobirds.org/Publications/ColoradoBirds/InTheScope/93.pdf 2 Quote Link to comment Share on other sites More sharing options...
