Every summer growing up I remember hearing a strange "mew" as part of the regular neighborhood ambient noise. Though I never saw what it was, I figured it was either a squirrel or even a cat. It wasn't until just a few years ago I realized the sound I had been hearing all that time was actually, haha, a catbird!
They can mimic sounds to make their very own song and just today I saw one in the tree sounding like a robin who had not practiced his call enough times. Such a copycat (har, har)!
I've been trying to get a picture of a catbird for several years and finally got it!
