Turkey vultures have returned to Front Range

Some people watch for the first robin of spring. In Capistrano, they look for the return of the swallows. I know it’s spring when the turkey vultures return to the Front Range of Colorado. (https://amylaw.blog/2013/04/08/it-must-be-spring/)

Turkey vultures are big birds — the biggest you are likely to see, with the exception of an eagle or an American white pelican.

You’re not going to mistake a vulture for a pelican. The others are a little more problematic.

They are big, dark bird with translucent (almost see-through) trailing wing feathers, and a red head.

I have the most trouble telling a turkey vulture from bald or golden eagles. Although golden eagles may hold their wings in a slight “V”, most often they hold their wings flat.

A turkey vulture soars with it’s wings in a slight “V”, often called a “dihedral”.

Turkey vultures are also “tippy” when they fly — they are so light that air drafts bounce them around. Eagles are not “tippy”. It’s beneath their dignity.

And neither a bald or nor golden eagle have the translucent trailing wing feathers.

Swainson’s hawks, or a broad-winged hawks are both tippy and fly in a V. But both these hawks have shorter, broader wings, and are smaller. They also often brownish-red and have white markings on their wings or bodies.

You might confuse it with a black vulture, but black vultures just seem smaller overall — shorter wings, much shorter tail, with a dark grey head. Plus, black vultures are limited to the southern US down into South America. I have to travel south if I want to see a black vulture.

It’s been a long, hard winter. I hope you enjoy your first signs of spring, whatever they are!
