The black birds were very disturbed the evening that we went to Lurie gardens ...
Here they are mobbing a pair of crows ...
watching and calling on a light post ...
Two crows calling on the building across the street ...
A Robin on alert ...
and a Grackle's intense stare ...
But they were not at all concerned with this Big Bad Bird (Great Horned Owl)
The blackbirds were dive bombing the Kestrel so we had to move him into the tent. He was the culprit ... I learned something that had never occurred to me before. This American Kestrel is a diurnal hunter ... a threat that all of the dirural birds recognized ... but the Owl, a nocturnal hunter, posed no threat to them because they never see them hunt. I thought that was pretty amazing :)
