Re: Unusual kestral nesting site?

I first noticed kestrels nesting in these marker balls about 8 years ago, but this nesting behavior is noted in the Bird Atlas so it had been going on for quite some time previous to that. 

I’m very curious to know about the success rate of breeding attempts in these marker balls. They must get really hot, they swing around in the wind, and they are usually 200’ or so in the air so that first flight better go well! At least snakes aren’t
going to be a concern.
