This heron is found as a summer resident in all suitable localities through 

 the Middle Region, and in about equal numbers in Arizona and New Mexico. 

 We saw it on the borders of Utah Lake as late as December, and it 

 probably remains there through the winter. In Arizona, it appears to be 

 resident.
