Discover the avian wonders that southern Idaho has to offer and seek out the special endemic Cassia Crossbill in its tiny world range!

With its 58th Supplement, the American Ornithological Society split off the Cassia Crossbill from the Red Crossbill complex, giving it full species status. This created not only the newest United States endemic, but also one of the most endangered species in our country. Basically limited to Idaho’s South Hills and Albion Mountains, a tiny range comprising only 70 square kilometers, the Cassia Crossbill is surely one of the hardest species to add to one’s life list. This tour will be devoted to finding this special new species, but also to introducing birders to the fabulous birding in the state of Idaho.

We will concentrate on the south-central portion of the state where a good variety of habitats occur. Open grasslands and marshlands could yield such species as Trumpeter Swan, Western and Clark’s grebes, Ferruginous Hawk, Prairie Falcon, Gray Partridge, Long-billed Curlew, and Brewer’s Sparrow. Foothill areas with junipers and oaks could produce such gems as Golden Eagle, the highly sought Pinyon Jay, Woodhouse’s Scrub-Jay, Juniper Titmouse, Canyon Wren, Mountain Bluebird, Townsend’s Solitaire, Sage Thrasher, Virginia’s Warbler, and Green-tailed Towhee, while riparian tracts are home to Lazuli Bunting, MacGillivray’s Warbler, and Bullock’s Oriole. Finally, in the higher elevation pine forests, we will seek out such species as Calliope Hummingbird, Lewis’s Woodpecker, Red-naped Sapsucker, Hammond’s and Dusky flycatchers, Western Tanager, Red Crossbill and, of course, our newest species, the Cassia Crossbill.

Good accommodations; easy to moderate walking; much roadside birding; some longer drives; moderate temperatures.
