I lucked out the other day and spied an entire kestrel family on the Lower East Side. They nest in a tiny hole in the cornice of a building on Stanton and Clinton Streets.
Here are the two babies:
While I watched, there was some commotion across the street. I looked up to see the two kestrel parents chasing a pigeon over the buildings. The pigeon dove into a hole about two feet over from the babies. Mama kestrel followed the pigeon and gave it a loud scolding.
Threat averted, the two parents perched on a nearby cell tower to keep an eye on the nest.
Mom appears to have lost a tail feather.
Eventually, the drama died down and Pigeon was allowed back on the premises...
