Apparent flush-foraging in a crested guan (Penelope purpurascens) family party
摘要
Crested guan (Penelope purpurascens) is a large, primarily arboreal Cracid with an incompletely understood breeding ecology. Here we present novel camera trap observations of a family party (two adults and three chicks) engaging in what is likely flush-foraging behaviour in Cusuco National Park, Honduras. The footage shows a parent (likely a female) assisting juveniles apparently foraging for invertebrates and/or fallen fruits in the leaf litter, repeatedly fanning its tail and bobbing the torso, wings and tail up and down systematically, while the three juvenile birds followed directly beneath and behind, mimicking the movements of the parent. Additionally, the juveniles appear protected underneath the wings of their parent, which may allow them to spend more time foraging and less time being alert to predators. This behaviour has been previously observed in other Cracids, but not for this species. Our observations also provide evidence of brood size and likely bi-parental care behaviour, adding to the understanding of crested guan breeding biology.
