Thanks to Deniz for posting and to Geoff for sending his photos of the immature Ferruginous .... watching this bird approach the trapping station and slowly walk/hop (not fly) its way into the trap was pretty cool! I just wanted to add one more picture (also by Geoff) - this one of Kyle (a hawkwatcher) holding its wings open:
In other news, songbird #s have been moderate but diverse and today (9/5) was our best day of the month so far (64 new, 8 recaptures). We're getting more adults of the Neotropical migrants and are also starting to catch increasing #s of WC Sparrows and RC Kinglets. The vast majority (> 99%) of the White-crowned Sparrows that we capture at Lucky Peak are of the Gambel's subspecies ('West Taiga' in Sibley) but today we banded an adult of the Mountain subspecies ('Interior West' in Sibley) - differentiated by the darker, pinker bill and the dark feathers on the lores (just behind the bill). Here are 2 shots:
Another capture worth highlighting today was an adult Cassin's Vireo looking very bright & fresh. As this is the time of year when vagrant Blue-headed Vireos are most likely, I thought I'd post a couple shots of this sharp Cassin's as a basis for comparison with any potential Blue-headeds. Notice that although this bird is quite bright, especially on the flanks, there is not a sharp contrast between the head and back and that there is a green infusion in the otherwise grayish head feathers seen from all angles.
Raptor #s are starting to pick up and the next month promises to be awesome (unless its raining). I saw an immature N Goshawk on Monday and Merlins are due any day now ....
OK, all for now - happy birding,
Jay
