hawk finds a finch bird feeder the perfect perch

Lately he’s been perching on the finch bird feeder, a good central spot offering spanning views of the yard and unassuming victims. Last week when I looked out, there were actually two hawks, (a double omg!) so one must be a juvenile. They’re so darn big it’s hard to tell!
The last few days I haven’t seen them, but have witnessed strange behavior from the Blue Jays. They’re screaming wildly and loud, almost as if to mimic the hawks. Someone once mentioned Jays will do this to keep hawks away. Well, if that’s the case, then bravo to these smart birds who some find to be a nuisance.
By the way, this feeder is fitted with a 30″ Seed Hoop which catches waste and attracts some other birds who never use the feeder itself.
