The mexico-anonymph ( Thalurania ridgwayi ) is a species of bird from the hummingbird family (Trochilidae). The species is endemic to Mexico . The stock is on the IUCN as endangered ( Vulnerable estimated).
features
The Mexikonymph reaches a body length of approx. 9 to 10 cm with a weight of approx. 3.5 to 4.2 g. The males have a straight black beak. The front skull shimmers violet blue, the back skull bluish green. The rest of the top is green. The throat glitters emerald green, the belly and the under tail-coverts are dark green. The tail is slightly forked and bluish black. The top of the female is similar in color to that of the male, but they have a small white point behind the eyes. The underside is grayish, the sides of the chest have green spots. The slightly forked tail is also bluish black, but the central control feathers have a greenish tinge. The outer control springs are spotted white.
Behavior and nutrition
The nectar involves the Mexico nymph probably similar to other species of the genus Thalurania of flowering Rötegewächsen , ginger plants and epiphytes such as bromeliads , heather plants and mistletoe . Arthropods are both collected from foliage and hunted and caught in the air.
Vocalizations
The singing consists of irregularly repeated liquid tsip sounds. Often these are uttered in quick series of 2 to 4 sounds that sound like a liquid shaking. Most of the time, they utter these tones in a hovering flight.
Reproduction
The only thing that is known about reproduction is that they were observed in a breeding mood while collecting in February and March.
distribution and habitat
The Mexikonymphe prefers moist forests, gorges and mountain foothills at altitudes between 250 and 1200 meters. A precise delimitation of their habitat has not yet been scientifically researched. You can probably also find them in coffee plantations. They are native to the mountain slopes facing the Pacific in the south of Nayarit , in Jalisco and in Colima .
migration
The mexico-anonymph is a resident bird .
Subspecies
The species is considered to be monotypical .
Etymology and history of research
Edward William Nelson described the Mexicanonymph under the current name Thalurania ridgwayi . As the location of the type specimen that he had collected together with Edward Alphonso Goldman , he named San Sebastián del Oeste . John Gould introduced Thalurania in 1848 for a subspecies of the swallow nymph ( Thalurania furcata viridipectus ). »Thalurania« is derived from the Greek words »thalos, τηαλοσ « for »child, descendant« and »ouranos, οὐρανός « for »heaven«. The specific epithet »ridgwayi« is dedicated to Robert Ridgway (1850–1929).
