The universe has conspired to keep me out of the field for far too long. My one link to sanity, if you can actually call birding sanity, is the activity at the bird feeders.
The Portland area has seen a massive invasion of Pine Siskins in recent weeks. Numbers at my feeders have tapered off in the past week, but the nyjer feeder is still popular. This photo shows six Pine Siskins, a colorful male Lesser Goldfinch, and an American Goldfinch peeking around from the back.
This little guy has been the avian star of our property for the past month. There seems to be an irruption of Mountain Chickadees in western Oregon this year, with many reports from the Portland area, and some from as far as the coast. Even when he is turned away, he stands out from the common Black-capped Chickadees by his gray back and the narrower band of black on the nape.
The white stripe above the eye is the characteristic field mark for this species. Most reports of Mountain Chickadees in the area have been of birds with thick white eyebrows and white lores, which suggests birds from the eastern half of Oregon and into the Rockies. This bird has a narrow white brow and black lores, suggesting a bird from the nearby Cascades. While it is tempting to assign birds to subspecies (especially since Mountain Chickadee might be split into two species in the future), David Sibley warns against trying to make such distinctions, as there is a lot of overlap of characteristics between subspecies. His essay on this topic can be seen here.
