Grasshopper Sparrow (Ammodramus savannarum ammolegus) egg dimensions in Arizona 2013

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 2013, the dimensions (length and width) of 1–2 eggs were measured in a randomly selected subset of nests as soon after the nest was found as possible.
