The rose warbler ( Cardellina versicolor , Syn . : Ergaticus versicolor ) is a small songbird from the forest warbler family (Parulidae). The species occurs in Mexico and Guatemala . It has been listed as "Vulnerable" by the IUCN since 2000.
features
Rose warblers reach a body length of 13 centimeters. The wing length is 5.6 to 6.6 centimeters in the male and 5.7 to 6.2 centimeters in the female. Adult rose warblers have a pinkish-silver head plumage and a dark pink forehead, between the beak and the eye it is a little darker. The rest of the head plumage as well as the neck area, throat and belly area are pale silver-pink. The top is red with maroon shoulders and cloak. The wings are dark brown and the underside is purple in color. The beak is dark brown; the legs flesh-colored.
Occurrence, nutrition and reproduction
The occurrence is limited to southeast Mexico ( Chiapas ) and the highlands in Guatemala from the east to Sierra de las Minas . The animals inhabit cypress forests , pine forests , mixed pine and oak forests and forest edges with dense undergrowth at heights of 2000 to 3800 meters, but are mainly found above 2800 meters. Their diet consists mainly of insects and other invertebrates , which they mainly look for in the thick bushes.
The nest is made on the ground. It is shaped like a dome with a side entrance. Rose warblers use pine needles as nesting material and moss for the interior. A clutch consists of two to four eggs. The breeding season is eleven days. The young birds fledge after ten to eleven days.
Endangerment and existence
The IUCN lists the species as "endangered" (Vulnerable), the main threat is the strong fragmentation and persistent destruction of the forests used as habitat. The rose warbler was rare in Chiapas in the mid-1980s, possibly due to the eruption of the El Chichón volcano in 1982, which covered large parts of the area with ash. In the late 1980s, stocks increased slightly. The bird protection organization BirdLife International estimates the population at 20,000 to 50,000 individuals.
