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.

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