TL;DR
This comparison of Sage Sparrows and Brewer's Sparrows using observations gathered over several years on two plots at a single location shows how they do or do not differ in their behavior and habitat use.

The relations between bird distribution and abundance and habitat characteristics at a regional scale of investigation, using surveys conducted over three consecutive years on 14 plots at nine locations in the shrubsteppe of the northwestern Great Basin of North America, suggest that bird populations in this system vary largely independently of one another.

Several factors that complicate bird-habitat analyses at different spatial scales are explored, and it is concluded that these problems of scale are most likely to be circumvented by conducting studies at several hierarchically nested scales arranged on clearly defined environmental gradients over a reasonably long period of time.

This experimental manipulation of habitat composition and structure within territories of birds breed- ing in the Artemisia-dominated shrubsteppe of central Oregon is complicated by influences of time lags on individual and pop- ulation responses that may stem from site tenacity by breeding adults, leading them to return to previous breeding locations in years following the manipulation despite the habitat changes.

It is suggested that Sage Sparrows may have a simple, single-song repertoire because the song serves simple functions, and selection favoring a more elaborate song may be absent.

Analysis of territory size and its variations in two common species of shrubsteppe birds and its relationship to population densities and features of breeding habitats casts doubt on the meaning or value of "average" territory-size measures for a species as a whole.
