Grasshopper Sparrow (Ammodramus savannarum ammolegus) nest measurements Arizona 2011-2013
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 2011 through 2013, I took nest measurements within a week of nest failure or fledgling. However, in 2011, the first year of nest monitoring, I measured 17 nests more than 7 days after nest completion. Measurements included: nest opening, inside diameter, inside depth, nest height, orientation of nest opening, length of tunnel, and nest concealment.
