Over 200 species of birds inhabit the riparian (areas located near water) and upland habitats at Montezuma Castle National Monument. Although the number of species observed each month is highest during the breeding season, partly due to a large number of migrating birds, species richness is high during non-breeding seasons as well.
During the breeding season, Black-throated Sparrows, Bewick's Wrens and Brown-headed Cowbirds are among the most common species. Because a variety of habitats are present, even the most predominant species in a given year accounted for no more than 12% of the species observed. The number of breeding species within the monument (49) is high, given the small area, and reflects the topographic and habitat variability that occur here and the presence of substantial amounts of good quality riparian habitats.
Approximately 75% of the breeding species are neotropical migrants and, therefore, leave the monument and Verde Valley during the fall or winter following the breeding season. As a result, there is a major change in the ecology of the monument between breeding and non-breeding seasons. Similar patterns have been shown along the Colorado River in the Grand Canyon. In fact, most of the riparian breeding species in the Southwest are neeotropical migrants that winter elsewhere, such as Central and South America.
The Sonoran Desert Network has put together a Top Ten list for the birds of Montezuma Castle and Montezuma Well. The numbers are based on visits during the months of May and June. Read below, and see how many you can see the next time you're at one of the sites!

Spring is a beautiful time at Montezuma Castle National Monument. Beware this flower, though: this Sacred Datura, or Jimson Weed, is toxic if eaten.
