The tooth-billed hummingbird ( Androdon aequatorialis ) or hooks hummingbird is a bird species of the family of hummingbirds (Trochilidae). The distribution area of this species includes the countries Ecuador , Colombia and Panama . The IUCN assesses the population as Least Concern .
features
The tooth-billed hummingbird reaches a body length of about 14 cm, of which the relatively long straight beak is 41 mm. While the upper bill is black, the lower bill is yellow. The front upper head of the male has a copper-red color. The rest of the top, with the exception of the copper-red rump, is bronze-green. The upper tail covers are decorated with a striking white band. The rounded tail is gray green with a dark border at the end. The hem is streaked with broad white spots. The throat and belly are adorned with wide black stripes. The coloring of the females looks a bit duller, which is particularly noticeable on the top of the head. They also have fewer stripes on the bottom.
Fledglings are similar to females but have a bluish neck
behavior
They move very quickly in the forests in the area of the lower strata down to the lower part of the treetops. Occasionally, you can spot them at the edges of the forest. They collect their nectar by flying back and forth very quickly in front of the blossoms, for example the balsa trees or the ant trees . The beak points upwards and the tail snaps upwards. They also occasionally visit flowers to take in nectar. They probably use the conspicuous teeth to catch insects. Usually they are traveling alone and often also fly to epiphytes .
Vocalizations
Her call sounds like a sharp piercing cheet that now and then doubles as cheet-it . Occasionally one hears a series of bright- sounding tsit-tseé-tsu or tseé-tsu .
distribution and habitat
You see them only rarely and very sporadically in damp forests and at the edges of the forest in the lowlands and hilly landscapes. In Panama they occur only in the east at altitudes between 750 and 1550 meters. In Colombia their range extends to the humid lowlands of the central and western Andes. To the south this extends in the valley of the Río Magdalena to the municipality of Remedios in Antioquia . In Ecuador, they are mostly found in the mountain forests, lowlands and hills of the northwest. Here they are mainly present in the Esmeraldas province . Especially at Playa de Oro, they are relatively common at altitudes between 100 and 800 meters. Few reports describe occurrences in the west of the Pichincha province and on the coastal mountains of the Cordillera de Mache .
Etymology and history of research
John Gould originally described the hummingbird under its current name Androdon aequatorialis . Gould received the type specimen from Ecuador.
The term “Androdon” is derived from the Greek words “anēr ἀνήρ , andros ἀνδρός ” for “man” and “odous, odōn” for “tooth”. The Latin epithet »aequatorialis« stands for »equatorial, belonging to the equator «, but was often used for animals from Ecuador .
