Chrysophlegm is a genus of birds in the family of woodpeckers (Picidae). The genus includes only three small to medium-sized species that inhabit parts of South and / or Southeast Asia. All three species are closely related to forests, two of the three species mainly inhabit the evergreen tropical rainforest, the third species, the yellow-necked woodpecker ( Chrysophlegma flavinucha ), inhabits a broader range of forest types. All species look for food almost exclusively on trees, which primarily consists of ants and termites . The IUCN classifies the three speciesas “least concern”.
description
They are small to medium-sized woodpeckers with a long tail, a pronounced feather bonnet and, depending on the species, a very short or long, slightly or clearly chisel-shaped, pointed beak and broad at the base. The beak is bent down at the ridge. Two types are predominantly green on the upper side with a gloomy and unmarked underside of the trunk, the third type, the red lead woodpecker ( Chrysophlegma miniaceum ), is predominantly rust-red on the upper side and unobtrusively light and dark banded on the underside. The species show a not very conspicuous sexual dimorphism in terms of coloration .
Systematics
The genus includes three types:
- Yellow-naped woodpecker ( Chrysophlegma flavinucha ) ( Gould , 1834)
- Drip-throated woodpecker ( Chrysophlegma mental ) ( Temminck , 1826)
- Red red woodpecker ( Chrysophlegma miniaceum ) ( Pennant , 1769)
The three species have so far been placed in the genus Picus . After a molecular genetic investigation of several sections of the DNA , these three species form a monophyletic group, whether this group is the sister taxon of all other species of the genus Picus or is further away from them could not be determined with certainty. The genetic distance between these two groups is just as great as between other woodpecker taxa treated as different genera, so the authors of the study suggest separating these three species as a separate genus Chrysophlegm . The International Ornithologist's Union (IOC) has already followed this suggestion.
