Foraging behavior and association with mixed flocks by the Critically Endangered Alagoas Tyrannulet Phylloscartes ceciliae (Aves: Passeriformes: Tyrannidae)
The Alagoas Tyrannulet Phylloscartes ceciliae is a Critically Endangered species with a restricted distribution to the Atlantic Forest of the Pernambuco Endemism Center. It seems to specialize in using the sally-strike maneuver (68.85%) to catch prey on green foliage (50.82%) and in the air (34.42%). We calculated a catch rate of 2.93 catches/minute, identified a new food item for this species (caterpillars), and included 12 species in the list of birds recorded in mixed flocks with the species. Our results show that majority of the prey capture events by Alagoas Tyrannulet occurred inside tree canopies, thus we can infer that this species needs a more advanced stage of forest sucession, with higher trees, emphasizing the urgency for restoration programs in the region.
