Philadelphia Vireo

I'm glad so many readers enjoyed last months topic, birds and wildlife of the Caribbean. Before we move off to our next adventure I thought I'd cover some of the recent local birds we've observed.

The slight, almost dainty Philadelphia Vireo is fairly common in dense young woodlands of Canada’s boreal summertime. Smaller, shorter-billed, and less aggressive than a Red-eyed Vireo, this olive-brown bird moves methodically through upper reaches of young trees searching for caterpillars.

Although similar to the widespread Warbling Vireo, it’s usually yellower below with a bolder head pattern.

The song is a rising-and-falling series of short whistles, quite different from Warbling but very similar to Red-eyed, making this species both a challenge and a prize to find during migration. Cornell All About Birds
