Over the past few nights, I've heard a male mockingbird calling for a mate, and let me just say that it's incredibly surreal to hear a bird calling at 2 AM. I heard him start calling at 9 PM or so on Saturday night and took my phone out to record the calls.
This is what I got after removing background traffic noise and wind with Audacity:
I'm impressed with the variety of calls, and it was easy to isolate his call at night because all the other local birds were quiet. He's so lonely!!!!!
Last year I spotted a Mockingbird fledgling clambering around the arbor:
It's a bad photo, but I'm lucky to have gotten any at all since he was NOT impressed with my snooping. The parents were also keeping an eye on me.
