[UNCLASSIFIED] Black-shouldered Kites

When I drove to Boorowa last weekend I saw over 30 black shouldered kites. The most I have ever noticed. There seems to have been an influx recently. Not sure when it started, perhaps the GBS data will say. Esteban Fuentes talked at the Field Nats last year and his feeding study on Birds of Prey showed that nankeen kestrels and black shouldered kites had a different diet, nankeen eating mainly insects and BSK eating mice, small reptiles. I have had a mouse plague in my yard recently and perhaps this is linked to BSK immigration (well not just my yard- heh heh). Nankeen kestrels nest in hollows and BSK in stick nests.

These factors suggest they don't compete, yet I have not seen a nankeen kestrel for a while now. I suspect the two species do still compete, and perhaps when one is common the other leaves.


I thought John Ls comments on the BSK mating were interesting and am not sure why there were no replies. With only a few professional birders on the list I suspect it wasn't related to having a University degree or not.   Lots of emails arnt replied to.
