BLUE-HEADED VIREO – (Vireo solitarius)
The Blue-headed vireo is an insect eating bird of the forest. The name ‘vireo’ refers to the green color, and ‘solitarius’ means ‘solitary’. The head of this vireo is blue-ish grey, the back is olive green and the under parts yellowish except for a white belly. It has two whitish wing bands, and white ‘spectacles’. Some of their vocalizations resemble that of the American robin.
The bue-headed vireo breeds in PEI and is common. The majority of the population breeds in Canada. It is widely distributed through the eastern half of North America. However there is a high rate of hatchling mortality due to many predators raiding the nest, and because the nest can be parasitized by the brown-headed cowbird. The blue-headed vireo is known to build its nest near raptors that don’t prey on them, possibly as a type of protection.
The blue-headed vireo migrates to the south-eastern USA and Mexico, and Central America.
