A note on Blue-headed Vireos

Peak Blue-headed Vireo migration is just around the corner here in eastern Ontario. Typically this species pulses through in large numbers from mid September through to early October, with birds known to linger in favored migrant haunts well into October. Last fall, there was a large movement in Ottawa which occurred on, I believe, September 15th (can’t find these particular notes at the moment) where 5-6 Blue-headed Vireos were reported by multiple observers from numerous birding hotspots throughout the city. Blue-headed’s have a tremendous amount of character and they are typically quite vocal during migration. In my experience, I have found first year birds to be especially chatty, tending to merge their song bouts with squeaks and chatters. If you have yet to pause under a tree where a young Blue-headed is chatting away, I insist you do — it’s very special! In my opinion, the best of all the vocalizations this species is known for is the adorable tew-weh call: http://www.xeno-canto.org/87745

Happy Fall Birding.
