NOTES: ROBINS EXTENDING BREEDING RANGE INTO TUCSON

Abstract

American Robins (Turdus migratorius) have not been reported nesting in the hot desert areas of the southwest. On 18 June 1965 I found a pair nesting in a White Mulberry (Morus alba) near the University of Arizona in central Tucson, Pima County, Arizona (Snider 1965). The resident of the property told me a pair had successively bred there for 2 or 3 years. In 1966 a pair nested in the same tree and in the late spring of 1967 I saw a pair in the vicinity but a nest was not located.
