In my Topeka, Kansas yard on January 31, 2019 I was trying to get some video of house sparrows feeding on this sparrow trap. Find out why I trap house sparrows by following the link at the top of the video. No house sparrows showed up. Instead I got a recording of a bird call that I do not recognize. Some notes do sound like a northern cardinal, but other notes do not. In the background you can hear American tree sparrows.
This is what the area around the trap looks like. Many birds spend time in the shrub and below the shrub feeding on the ground. As an added benefit, I was counting birds for Project Feeder Watch the day before and the day of the video. You can find a link in the video description to all the birds I recorded in my yard those days. That should be enough background information. I’ll shut up so you can listen to the mystery bird.
That’s the end of the recording. If you have a guess to the identity of the calling bird, leave a comment.
