The Schmalschnabeltodi ( Todus angustirostris ) is a whisker in the Todis family (Todidae). Its distribution area includes the countries Haiti and Dominican Republic . The IUCN classifies the population as Least Concern .
features
The Schmalschnabeltodi reaches a body length of about 11 centimeters with a weight of about 6.7 grams. It looks tiny and bulky. The top is bright green. The red throat turns into a white with a yellow tint on the underside. The flanks are pale pink. The lower bill is reddish with a black tip.
Young birds lack the red on the throat and the breast is striped pale green.
The Schmalschnabeltodi is similar to the Breitschnabeltodi ( Todus subulatus ). Both have overlapping distribution areas, making them difficult to distinguish.
behavior
When the bird is sitting, the tail points straight down and the beak points up at about a 45-degree angle. He keeps turning his head in search of insects. It hunts its prey in short soaring flights . The beak audibly snaps shut. For the search for prey he usually prefers the denser lower strata . It incubates from April to June and lays 3–4 shiny white, unspotted eggs. He builds his nest in a chamber or at the end of a tunnel up to 30 centimeters deep in earth embankments. In the Sierra de Bahoruco , nests have also been discovered in tree hollows up to 9 meters above the ground.
distribution and habitat
The bird is endemic to Hispaniola and occurs there in the higher altitudes between 900 and 2400 meters, rarely up to 3000 meters. You can find it in dense, moist forests with moss-covered pines, liverworts , orchids , Spanish moss , ferns or climbing bamboo (Dinochloa). Occasionally he also visits coffee plantations. Occasionally you can see it in a slightly lower position. It prefers to live in ravines and on clay embankments.
Subspecies
A 2004 DNA study by Lowell Chester Overton and Douglas D. Rhoads found genetic differences between the populations of the Sierra de Neiba and the Cul-de-Sac plains and the occurrences in the Sierra de Bahoruco and on the southern peninsula of Haitis . The IOC World Bird List does not yet take these new findings into account.
Etymology and history of research
Frédéric de Lafresnaye described the species in 1851 in Revue et Magasin de Zoologie Pure et Appliquée under the current name Todus angustirostris . The bird received Auguste Sallé (1820-1896) in America, the type specimen was collected in the Saint-Domingue . Lafresnaye based the first description on the descriptions of the discoverer. "Todus" was the name for an unspecified bird in Cistellaria by Titus Maccius Plautus . This name was also used Sextus Pompeius Festus . Later authors use the name for the genera of the robin ( Erithacus ) and the redstart ( Phoenicurus ). The Jamaikatodi ( Todus todus ) was probably so named because of its small size and red throat and thus its resemblance to the robin. The name "angustirostris" is made up of the Latin words "angustus" for "narrow" and "-rostris" for "-beaked".
