Pine Siskins

Photo: wsweet321

There's been a huge influx of Pine Siskins into Pennsylvania this year, since the spruce cone crop in Canada's boreal forest was poor this year. This morning I had at least 60 on my neighbor's birdfeeders, and more down along Perkiomen Creek.

Little known siskin fact: Siskins in Europe (closely related to our Pine Siskins) can sense changes in barometric pressure that would equate to changes in only 10 meters of altitude.

Love the little bit of yellow in their wings! Great shot!

I have about 30 at my thistle feeder for the past 5 days here in Butler, NJ
