Hi Homo sapien! Welcome to Animal Database! Anyway, did you know that you're 60% genetically similar to banana trees?

Family Momotidae

Momotidae or motmot, a family of birds in the near passerine order Coraciiformes, which also includes the kingfishers, bee-eaters and rollers. All extant motmots are restricted to woodland or forest in the Neotropics, and the largest diversity is in Middle America. They have a colourful plumage and a relatively heavy bill. All except the tody motmot have relatively long tails that in some species have a distinctive racket-like tip.


Motmots eat small prey such as insects and lizards, and will also take fruit. In Costa Rica, motmots have been observed feeding on poison dart frogs.

Like most of the Coraciiformes, motmots nest in tunnels in banks, laying about four white eggs. Some species form large colonies of up to 40 paired individuals. The eggs hatch after about 20 days, and the young leave the nest after another 30 days. Both parents care for the young.

Motmots often move their tail back and forth in a wag-display that commonly draws attention to an otherwise hidden bird. Research indicates that motmots perform the wag-display when they detect predators (based on studies on turquoise-browed motmot) and that the display is likely to communicate that the motmot is aware of the predator and is prepared to escape. This form of interspecific pursuit-deterrent signal provides a benefit to both the motmot and the predator: the display prevents the motmot from wasting time and energy fleeing, and the predator avoids a costly pursuit that is unlikely to result in capture.

There is also evidence that the male tail, which is slightly larger than the female tail, functions as a sexual signal in the turquoise-browed motmot.

In several species of motmots, the barbs near the ends of the two longest (central) tail feathers are weak and fall off due to abrasion with substrates, or fall off during preening, leaving a length of bare shaft, thus creating the racket shape of the tail. It was however wrongly believed in the past that the motmot shaped its tail by plucking part of the feather web to leave the racket. This was based on inaccurate reports made by Charles William Beebe. It has since been shown that these barbs are weakly attached and fall off due to abrasion with substrates and during routine preening. There are however also several species where the tail is "normal", these being the tody motmot, blue-throated motmot, rufous-capped motmot, and the Amazonian populations of the rufous and broad-billed motmots.


While the species-level taxonomy of most motmots has been relatively straightforward, it has been argued that the blue-crowned motmot should be split into multiple species, among these the highland motmot (Momotus aequatorialis).
