Remember those photos of the Red-throated Caracaras in Nicaragua from last week? Here is the video of one of the birds, making alarm calls and holding a piece of a Polybia brood comb. This video comes from Pablo Elizondo, director of the Costa Rica Bird Observatories, who was with Mandred Bienert when they encountered the birds. I strongly suspect this bird is engaged in brood care, as the tail feathers are extremely worn, as if it is spending considerable time in a nest.
