In 2011 through 2013, when nests were found, notes were kept on whether it held eggs or hatchlings at the time of discovery, and how it was found. 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.

These data provide information about all vegetation structure measurements (except shrub point-centered quarter measures) taken on Arizona Grasshopper Sparrow nest plots in 2011 to 2013 on two study sites - Audubon Appleton-Whittell Research Ranch, and BLM Las Cienegas NCA - Davis Pasture - in southeastern Arizona.

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...

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.

In 2010-2013 a variety of measurements were taken from grasshopper sparrows captured as part of the study described below and referenced in the larger work citation of this metadata record. Measurements include age, sex, wing length, weight, and exposed culmen length. 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 is the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies.
