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



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



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



])robably remains there through the winter. In Arizona, it apj)ears to be 



resident.
