On a recent trip with my girlfriend, I visited Crater Lake in Oregon. What a cool place! Crater Lake was formed by a massive eruption about 7000 years ago, and it’s the deepest lake in North America at about 1900 feet. It took us all morning to drive around the rim.
Aside from the fascinating history and geology, there were lots of great birds, including Clark’s Nutcracker, Prairie Falcon, tons of Juncos, Western Tanagers, and so on. One little feeding flock we came across had kinglets, chickadees and warblers, and I got a shot of this bird:
Pretty cool! This is definitely a west coast warbler…if I look at the West Coast Finder in the Warbler Guide (p. 113), I see that the plain, all yellow face with a dark cap and nape and white throat and body is a unique combination – Hermit Warbler.
Just to take it a step further, I went to the Aging and Sexing section for Hermit Warbler – looks like this bird is a not an adult male (no black throat), and probably not a first-year female (pronounced streaking in the back), but I think that’s as far as I want to take it – adult females and first year males are similar, and this photo makes it hard to see any more useful details like the centers of the median coverts. So it looks like an AdF/1yM Hermit – that was fun!
