For the last few weeks, finch numbers have really increased in my backyard, thanks in large part to a cool double sock nyger seed feeder that really seems to draw in both American Goldfinches and Pine Siskins. My high counts have been 32 goldfinches and 5 siskins at one time.
The double sock stuffed with njyer seed really seems to maximize the amount of space for finches to feed on because they can perch anywhere they want, in whatever orientation they want to.
I particularly enjoyed watching the Pine Siskins because they are not as common, especially in this part of Pennsylvania. Finches are definitely moving south further this year than is typical according to reports. In the photo above you can see the distinctive pointy bill that the siskins sport. The golden edging on the flight feathers and wingbar can be seen as well as the streaky undertail feathers.
