Given the way that they flock at this time of the year, I've always associated the month of September with American Goldfinches. And it's gotten to the point where I sometimes refer to it as "Goldfinch Month." By approximately mid-September, flocks of 40-50 "AMGOs" at my nyjer and sunflower feeders are commonplace. Towards the end of the month, their numbers reach or exceed the century mark (I counted 91 in the backyard five minutes ago). While I appreciate having goldfinches at my feeders (especially the males in their bright yellow breeding plumage), they begin to wear on me at this time of the year. Not only does it cost me about $25 a week to keep my feeders filled at this time of the year, but much of the spilled seed begins to grow mold and I'm actually forced to excavate and dispose of infected soil and seed under my feeders to keep the area from becoming an avian bioharzard. (Always a fun time on a Saturday afternoon.) Thankfully, in a few weeks, the large flocks will thin out significantly and I can return to appreciating the smaller portions of goldfinches.
In the midst of this goldfinch blitzkreig, there have also been a few exciting recent sightings. A couple of them have literally emerged from the flocks themselves. On two separate occasions over the past week, I've spotted lone Pine Siskins foraging with them. Siskins often join flocks of other finches to forage for seed in late summer and fall. Interestingly, another individual that I stumbled upon while photographing one of these goldfinch flocks was a female Black-throated Gray Warbler. This was pure coincidence, as warblers do not forage with finches. Black-throated Gray warblers trickle out slowly in August and September during their fall migration. I imagine that this individual was the last that I'll see in the yard until May.

In terms of local year-round species, Red-breasted Nuthatches and Black-capped Chickadees have been representing in relatively high numbers over the past month. Chestnut-backed Chickadee numbers, on the other hand, have fallen. Their movements tend to be unpredictable, so I'm not terribly surprised. A hatch-year male Anna's Hummingbird has become a permanent fixture at the nectar feeder, and hopefully he'll hang around for the winter as well.
