Observation details

Apparent Hatch Year Brown-capped Rosy-Finch. Photos sent to Rosy-Finch Banders in New Mexico and confirmed as a Brown-capped. Record submitted to UBRC, however there was a split vote with some saying HY GCRF can look like this. To be fair, juvenile plumage GCRF can have a head pattern like this with no gray, but are overall darker with extensive buffy feather edging in the wings and tertials, however after completing their 1st post-juvenile molt into basic 1 plumage, they have a typical 1st winter GCRF head pattern with bright silver on at least the supercilium and in 10 years maintaining these feeders I have not seen another 1st winter Rosy-Finch with this dull of a head pattern at Alta, and according to BOW molt graph, juvenile GCRF should complete molt to Basic 1 no later than the 1st week of November and typically before migrating from nesting area. So, I stand by this observation as a BCRF 1st cycle Basic 1, probable female
