Habitat requirements for successful nesting of hummingbird species in the Madrean Pine-Oak woodlands of southeastern Arizona
Project Description Two recent studies have shown that sites in southeastern Arizona support large numbers of hummingbirds, particularly during southbound migration. Results from HMN’s monitoring work in southeastern Arizona suggest that the Madrean pine-oak woodlands support the largest number of hummingbird species in the Sonoran Joint Venture region. However, little is known about habitat requirements

Use of restored riparian habitat in the Colorado River delta in the overwintering period
Project Description This project will (1) describe the wintering ecology of Neotropical migrants in riparian habitat in the Colorado River delta, Baja California and Sonora; and (2) evaluate the value of riparian restoration efforts for migrants during the nonbreeding period. PRBO is relating bird use, overwinter site persistence, and survivorship to silvicultural practices, water flow
