its habitat varies from the sea level to approximately 1500m of altitude. One research project studying a few pairs of this species found that their territory extended over 35-40 ha. Conservation status This species has been classified as vulnerable by the IUCN because of habitat loss. Deforestation is touching more territories and the plumbeous forest-falcon's habitat is being destructed. It is an unprotected species that needs to be studied more extensively to help its conservation. Efforts should be focused on the Chocó area where this organism is solely contained. Behavior Vocalizations Two main types of vocalizations are known for this bird. They produce some yapping kew notes every 1.5 - 2.5s, as well as series of cah cah cah-cah-cah that may be sung by pairs. Three types of calls and songs are known for the forest falcons. The most common one is the "territorial advising song". The plumbeous forest-falcon repeat series of five notes to claim his territory. Furthermore, the "excited cackling call" and the "quacking song" are also heard from Micrastur species, even though less often then the first call. Two members of the same species sometimes sing in a pair. Diet Due to the lack of study, the diet of this forest-falcon is not perfectly known. However, it is most probable that it is an opportunistic predator feeding on small vertebrates and large invertebrates. Land crabs, birds and lizards were found in the digestive system of a few individuals. Its main source of food is thought to be lizards. Moreover, this family of birds prey on forest-dwelling birds and rodents. They have two principal ways to forage. With the first one, they remain on the ground while running after the prey that they eventually catch with their feet. They keep their tail high when they chase the prey. The second technique consists of being perched about 2m above the ground, looking for sounds and movements in the leaf litter and then jumping on the detected prey. Reproduction The plumbeous forest-falcon's reproduction is not really known but it probably sets up its nests in tree cavities. As a matter of fact, other members of the Micrastur family that have been more studied, such as the collared forest-falcon and the barred forest-falcon, nest in trees.
