Field Marks and Identifying Characteristics: |
I'll break this down into the morning and afternoon sightings Morning: I had arrived at Alta to lead a bird survey, but knowing morning is the best time to see Rosy-Finches at the feeders, I made a quick check to see if anything was there. At this time it was lightly snowing. I got to the feeder at the Police offices, and there were many Rosy-Finches there. After taking some photos and looking for Blacks(which I found),one Rosy-Finch caught my eye,perched in an aspen right above the feeder. First thing I noticed was it appeared lighter brown,not as deep of a chestnutty color to it as the Gray-crowned, it also just had a frosted look to it. It also had very a bright pink belly,wing coverts and rump of an adult. So I started taking photos as well as looking in the binos at it, it had a very dull sooty blackish cap,lacking the bright silvery gray that Gray-crowned usually have. It was very tame, and perched fairly low in the tree, so I got great looks at it for several minutes, but was late for my survey so couldn't linger. Afternoon: After the survey I promptly returned to the office feeders to look for more Rosy-Finches. The storm had intensified to near white-out conditions, which is actually the best time to see large numbers of Finches at the feeders, and I wasn't disappointed. A large flock of 100+ Rosy-Finches and a few Pine Grosbeaks were actively feeding. Because of the heavy snow, I went inside the office and observed and photographed them through the window. I scattered some seed right out side the door on the path way, and within minutes, finches were feeding en masse just feet outside the window. I watched and photographed them for over an hour. Briefly I caught a glimpse of a Rosy-Finch with no gray in the crown, but was never able to get a second confirming look, but upon review of the photos after I got home I had one photo with an apparent adult, and a possible immature Brown-capped Rosy-Finch (see photos) |
Song or call & method of delivery: |
Typical Rosy-Finch calls heard, none for certain came from the
birds in question |
Behavior: | 8:30am adult was perched in an aspen right above the feeder just loafing, the 12:30pm sighting the bird(s) were feeding at the feeders in a mixed species Rosy-Finch flock |
Habitat: | Mixed upper montane forest of Aspen-Spruce/Fir, on the edge of town, feeding at bird feeders I put up especially to attract Rosy-Finches. Alta is famous for its Rosy-finch flocks in winter |
Similar
species and
how were they eliminated: |
Black Rosy-Finch have a blackish rather than brownish body. Some immatures can appear rather dull, but in my experience are
more mousey gray, rather than the brown of a Black-capped. Also all Black
Rosy-Finches have a bright silvery gray,high contrast cap. Gray-crowned Rosy-Finch are more difficult to distinguish. The coastal 'Hepburn's' race is distinctive with its all gray head,including cheeks, but the 'Interior' pose a real identification challenge. However, in my experience from watching these finches at close range this winter, all 'Interior' Gray-crowned,even immatures, have a bright silvery gray crown and nape, with black limited to a small area on the forehead. In immatures the gray is duller, and the may have some blackish in the crown, but the nape is still very grayish. In addition to the cap pattern, Gray-crowned adults are also have a richer chestnutty rufous brown tone,especially to the breast and back, whereas Brown-capped are a dull lighter brown,appearing frosted because of pale feather edging. Also adult Brown-capped have brighter pink markings,going farther up onto the belly than a Gray-crowned |
