In the arid grasslands that constitute Petrified Forest National Park, temperatures range from below freezing to above 100°F, providing a unique habitat for southwestern birds including raptors, songbirds, and warblers. By 2050, 18 species of birds could be extirpated from the park in the summertime including the iconic Gray Flycatcher, Sage Thrasher, and Sagebrush Sparrow. The Horned Lark, the only true North American lark, is the park’s most abundant bird species. But that may change, as the park’s climate is projected to become less suitable for the bird over the coming decades. As park managers respond to these threats, it is recommended they protect grasslands, streamside trees, and shrubs.

Suitable climate for these species is currently available in the park. This list is derived from National Park Service Inventory & Monitoring data and eBird observations. Note, however, there are still imperfections in these datasets.

These are species that may find the new climate conditions of this park suitable by 2050. But projected changes in climate suitability are not definitive predictions of future species ranges or abundances. Numerous other factors affect where species occur, including habitat quality, food abundance, species adaptability, and the availability of microclimates.

Within this park, suitable climate for these birds ceases to occur by 2050. Species may either adapt to the park’s new climate or may follow suitable climate elsewhere.
