CONSERVATION:

Winters from n Mexico s to Oaxaca. Frequent Bronzed Cowbird host. Range expanding northward in CA, likely due to extensive plantings of palms and flower-bearing ornamentals.

Uncommon and local migrant and summer resident, nesting almost exclusively in fan palms. Often observed near such palms inside the Main Quad and in the faculty housing area (e.g., Frenchman's Road).
