Narrow-billed tody

The narrow-billed tody (Todus angustirostris) is a species of bird in the Todidae family, and one of two Todus species found on Hispaniola, along with the broad-billed tody (Todus subulatus). It is found on Hispaniola (Haiti and Dominican Republic). Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.

Taxonomy and systematics

The broad-billed tody belongs to the genus Todus, of the family Todidae, the suborder Alcedines, order Coraciiformes and class Aves.[2] Originally, it was thought that broad- and narrow-billed todies shared a common ancestor and then split into two species, as they are the only tody species that share an island. However, mitochondrial DNA analysis has shown that the broad-billed tody descended from the Puerto Rican tody, while the narrow-billed tody descended from the Cuban tody, which was native to the island first.[3] The ancestors of the broad-billed tody migrated to the island two to three million years ago, meaning they have always been distinct species.[3] There has also been a question about where to place the family Todidae among other taxonomic groups, due to their similarities with other birds, such as the nightjars (Caprimulgidae), the trogons (Trogonidae), the puffbirds (Bucconidae), among others. In 1790, the genus Todus was established, to separate the todies from the kingfishers of genus Alcedo,[2] with the order "Todiformes" being proposed in 1882 but rejected. Currently, in combination with DNA, geographical and evolutionary analysis, it is firmly believed that todies belong to the order Coraciiformes.

gollark: In terms of hardware/expenditure per watt it may actually be worse for ages.
gollark: Cooler, but more expensive.
gollark: But apparently not all the random chemical waste?
gollark: It is probably not stable and people are obsessed with the very long term future of nuclear waste.
gollark: And it's highly true.
