What have we learned, so far?Lucifer Hummingbirds are more common than anticipatedRecaptures are numerous indicating a strong site fidelity; however, some individuals are noticeably trap shy affecting recapture ratesLUHU abundance peaks in August which coincides with the peak of migration for most other western US speciesSome individuals move between banding sitesBased on the recapture of two banded female birds from August 17, 2008, their ages are now 4+ years oldTypical of other small NA hummingbirds, LUHU females on the average have larger measurements than most malesID of HY M individuals can be determined by presence of gorget feathers, the wing cord length and/or the length or R1Despite 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 resourcesMale displays are spectacularNests are difficult to access and findThe Project is going well!
