I was having breakfast on our roofdeck this morning with my husband and we were enjoying a gorgeous summer day. Directly across from us on the next building there was a lot of commotion. A mockingbird was doing aerobatics flying at another bird on the roof. We got our binoculars to see what it was and the bird being attacked definitely was a raptor – a juvenile American kestrel! The Mockingbird was extremely agitated at this intruder and spent well over 10 minutes dive bombing him until the Kestrel, feeling rather put upon, flew away.
