Warbling vireo

Rondeau Provincial Park, Ontario, Canada, May 18, 2021.


A yard visitor, stayed above the water and came for a drink but didn't bathe.
Vireo gilvus
Brown-headed Cowbirds frequently deposit their own eggs in the nests of Warbling Vireos. In some instances, the vireo pair incubates the alien egg and raises the young cowbird until it fledges. Female vireos in some eastern populations, however, tend to puncture and eject interlopers’ eggs.
