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!
