Birds of the Tetons NP

Tons of birding guides out there but the best I've found is the Audubon site!

Here is a list of the most common birds in the park:

Bald Eagle - often seen nesting near water.

Western Tanager: A colorful bird that can be found in the forests, with males displaying red, orange, yellow, and black color

Calliope Hummingbird: The smallest bird in North America, weighing less than a tenth of an ounce

Osprey: Often mistaken for bald eagles, ospreys carry fish in their talons in a streamlined position

Greater-Sage Grouse: The iconic bird of the western states, with a courtship display in the sagebrush community in the spring

Tyrant Flycatchers: A robust bird with a strong bill that is mostly insectivorous

Trumpeter Swan: The largest waterfowl in North America, often found in pairs at Oxbow Bend, Swan Lake, and Flat Creek
