31. What have we learned, so far? • Lucifer Hummingbirds are more common than anticipated • Recaptures are numerous indicating a strong site fidelity; however, some individuals are noticeably trap shy affecting recapture rates • LUHU abundance peaks in August which coincides with the peak of migration for most other western US species • Some individuals move between banding sites • Based on the recapture of two banded female birds from August 17, 2008, their ages are now 4+ years old • Typical of other small NA hummingbirds, LUHU females on the average have larger measurements than most males • ID of HY M individuals can be determined by presence of gorget feathers, the wing cord length and/or the length or R1 • Despite being a desert adapted species, LUHUs concentrate at feeder station during times of extreme drought and/or invade higher elevation habitats searching for new food resources • Male displays are spectacular • Nests are difficult to access and find • The Project is going well!
