The cora hummingbird ( Thaumastura cora ) is a sailing bird in the hummingbird family (Trochilidae). It occurs in the South American countries Chile and Peru and possibly in Ecuador . The IUCN classifies the population as Least Concern .
features
The male cora hummingbird reaches a body length of about 13 to 15 cm. The female is significantly smaller and grows to between 7 and 7.5 cm. The short straight beak is about 12 mm. The upper side of the male shimmers in light green. The glittering magenta color of the throat fades into the side a little. The underside is grayish white with green spots on the side. The tail is about 10 cm long, with the predominantly white central control feathers being the longest. All other tail feathers are brown in color. The top of the female is also adorned with a light, shimmering shade of green. The underside is yellowish white. The significantly shorter 2 cm long tail is predominantly black with white spots. The central control springs are green.
Young males are very similar to adults, but have a speckled throat color and a white line on the chest.
distribution and habitat
They live oases in the thicket near river banks and foggy vegetation of the dry coastal landscape of Peru and the extreme north of Chile. In the Ancash and especially in the southern areas of the distribution area, they are found up to 3000 meters above sea level. You can often see them in cultural landscapes and gardens. In 1991 a female was spotted in the extreme south of Ecuador in the Loja province . Probably this is a random walk during their seasonal migration. Since the distribution area in Peru extends into the Piura region , a single occurrence in Ecuador cannot be completely ruled out.
behavior
Not much is known about their behavior. They fly to the undergrowth in the mountains to eat. It has been observed that they fly to the same plants as the turquoise-throated elf ( Myrtis fanny ). In certain areas and seasonally they can be found in greater numbers.
Vocalizations
The sounds that they utter while sitting on exposed branches consist of a quick, disorderly series of strong chip calls, electric humming sounds and beeping hums. The chip calls are sometimes made in quick series.
Etymology and history of research
René Primevère Lesson and Prosper Garnot first described the hummingbird under the name Orthorynchus Cora . The type specimen was captured by the officer of the frigate La Coquille, Mr de Blois de la Calande. It was only later that Charles Lucien Jules Laurent Bonaparte added it to the genus Thaumastura in his book Conspectus generum avium .
The word "Thaumastura" of the genus is derived from the Greek words "thaumas" for "wonderful" and "oura" for "tail".
The name "Cora" was given in honor of a sun priestess of the Incas in Jean-François Marmontel's 1777 novella Les Incas ou la destruction de l'empire du Pérou . So wrote Lesson:
