Northern mouse-colored tyrannulet explained

The northern mouse-colored tyrannulet (Nesotriccus incomtus) is a species of bird in the tyrant flycatcher family Tyrannidae. It occurs in a wide range of scrubby and wooded habitats in tropical and subtropical northern South America, being absent from the high Andes and dense rainforest. It also occurs in Panama and Costa Rica. It is generally common, but its small size and dull plumage results in it often being overlooked – or at least not identified, as it resembles several other tyrant flycatchers.

Two subspecies are recognised:^{[1] [2]}

• Nesotriccus incomtus eremonomus Wetmore, 1953 – Costa Rica and Panama
• Nesotriccus incomtus incomtus (Cabanis & Heine, 1860) – Colombia (northern and Andes) and northeastern Ecuador, east to Venezuela (except southern Amazonas), Trinidad, and the Guianas
