Blue-crowned Motmot

The Blue-crowned Motmot, Momotus momota, is a colourful near-passerine bird found in forests and woodlands of eastern Mexico, Central America, northern and central South America, and Trinidad and Tobago. As presently defined, it includes several taxa that possibly should be recognized as valid species, including the Highland Motmot, Momotus aequatorialis.

Description and behavior

Like most of the Coraciiformes, motmots nest in tunnels in banks, laying about three or four white eggs.

The Blue-crowned Motmot is 3848 cm long, depending on race. Nominate M. m. momota weighs about 145 g. The tail is very long with a bare-shafted racket tip. The upperparts are green, shading to blue on the lower tail, and the underparts are green or rufous depending on subspecies.

In all except the entirely blue-crowned subspecies coeruliceps, the central crown is black and surrounded by a blue band. There is a black eyemask, and the nape of momota is chestnut. The call is a low owl-like ooo-doot, although there are variations depending on the subspecies involved.

These birds often sit still, and in their dense forest habitat can be difficult to see, despite their size. They eat small prey such as insects and lizards, and will also regularly take fruit.


As presently defined, it is likely that the Blue-crowned Motmot includes several species level taxa. Especially the Andean Highland Motmot, Momotus aequatorialis , is frequently considered a separate species, but this treatment is no longer adopted here, following SACC (2005), which noted that the published evidence for treating it as a separate species is weak, but also hoped their decision would stimulate further research on the taxonomy of the M. momota complex. In addition to the Highland Motmot, several major groups have been identified: Amazonian Motmot , Whooping or Tawny-bellied Motmot , Blue-diademed or Lesson's Motmot and the 'true' Blue-crowned Motmot . Additionally, the taxon from Trinidad and Tobago, misleadingly named bahamensis (there are no motmots in the Bahamas), is distinctive, and possibly worthy of species recognition. Based on measurements, plumage and voice most of these group were considered to be species by Stiles (2009). The only exception was coeruliceps, which was beyond the scope of that study.
