is usually two or three eggs but up to five is not uncommon. The incubation period is 26 to 32 days and fledging occurs 32 to 41 days after hatch. Both sexes build the nest, incubate the clutch, and provision the young. Cognitive behavior The chimango caracara is an intelligent bird and has high problem solving abilities compared to other birds. "The explorative tendency, low neophobia and ability to innovate showed by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological success." Vocalization The chimango caracara is usually most vocal during the breeding season "particularly if human or other intruders [are] near nest", but also calls during disputes over food. Its most common call is a "loud petulant sqealing keeeeee-eh" that is usually made singly and often in flight. It also makes a "more chattering...keag-keah-keah..." or "ke-ew, ke-ew, ke-ew" and a "variety of squeals, growls, and hissing whistles." Status The IUCN has assessed the chimango caracara as being of Least Concern. It has a very large range, and though its population size is not known it is believed to be increasing. No immediate threats have been identified. "Currently thriving, perhaps benfitting in part from deforestation, and is commonest raptor through much of Chile and Argentina."
