    • Grasshopper Sparrow (Ammodramus savannarum ammolegus) clutch size measurements Arizona2011- 2013

    Metadata Updated: January 20, 2026

    Ammodramus savannarum ammolegus (commonly referred to as the Arizona Grasshopper Sparrow) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico. Although a subspecies of conservation concern, this data was produced as part of the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies. This study is described in the publication listed in the larger work citation of this metadata record. In 2011 through 2013, I recorded the number of eggs in each nest, once laying had ceased
