We have two tube shaped thistle seed feeders in our backyard and this week we have noticed flocks of Pine Siskins at the feeders. These sparrow-sized birds with a swath of bright yellow on their wings breed in Canada but spend their winters in our area. They do like to eat seeds from pine cones but will readily eat thistle seed from feeders.
We observed the siskins battling with House Finches and Goldfinches for the thistle seed we offered. At first glance you may think you are observing House Sparrows but looks closer for that swath of yellow on the males. Both male and female Pine Siskin have lots of stripes all over. The females don't have the yellow on their wings.
So hang up your thistle seed feeder and attract our wintering birds!
