The plumbeous forest-falcon (Micrastur plumbeus) is a bird of prey in the family Falconidae only found in the Chocó region in Colombia and Ecuador.

[5] The plumbeous forest-falcon differentiated about 3 million years ago after the split between trans- and cis-Andean South American populations.

[7] The closure of the Panama seaway, due to a drier and cooler climate linked to the formation of ice sheets at higher latitudes, may have highly contributed to the isolation of the plumbeous forest-falcon.

[2] One research project studying a few pairs of this species found that their territory extended over 35-40 ha.

[2] Deforestation is touching more territories and the plumbeous forest-falcon's habitat is being destructed.

The plumbeous forest-falcon repeat series of five notes to claim his territory.

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.

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.

[5] The plumbeous forest-falcon's reproduction is not really known but it probably sets up its nests in tree cavities.
