Unbanded Female Observes Impressive Courtship Display On Lance-tailed Manakin Cam – Mar 8, 2018
An alpha-beta male pair of Lance-tailed Manakins spend their morning courting an unbanded female at the display perch. Dr. Emily DuVal and her Lance-tailed Manakin research team track the behavior and breeding success of the birds at this research site by assigning each individual with leg bands that have a unique color combination. When watching the cam, you might notice that there are more male birds banded than females. Male manakins tend to stick around the area of their breeding site, so they are easily banded as chicks. On the other hand, female birds disperse farther than males, so the study site receives an influx of immigrant females every year after they fledge from nests elsewhere.

This cam shows one display perch in a population of Lance-tailed Manakins on Isla Boca Brava, Chiriquí, Panamá, that has been monitored intensively since 1999. Lance-tailed Manakins are small passerine birds in the family Pipridae that live in secondary growth forests of Western Panama, Columbia, and Venezuela.
