Hi Stewart. Several years ago, the Solitary Vireo was split into three
species.

The Eastern North American form became the Blue-Headed Vireo.
The Rocky Mountain form became the Plumbeous Vireo.
The West Coast Form became the Cassin's Vireo.

Subject: What is a Cassin's Vireo?


What species was the Cassin's Vireo split from or what is it a subspecies
of? None of my books mentions it. What distinguishes it from the species
it presumably had been lumped under.

In my travels I'm still seeing Marsh Hawks, Sparrow Hawks, Green Herons and
Whistling Swans among other extinct birds and my Robins are incontinent, so
no one can tell if I'm referring to the American ones or the European ones.

If anyone thinks I should get some of the newer books they can buy me one
and I'll happilly accept it, but I'll still call them Marsh Hawks.
