Purpurastrilde ( Pyrenestes ) are a genus within the family of the finch finches . They occur in three types exclusively in Africa .
description
Purpurastrilde reach a body length between twelve and fourteen centimeters. The male of the crimson tiger with its scarlet head, neck, chest and upper tail covers is one of the most spectacularly colored species of finch. The purple tiger and the small purple tiger also have a bright red head, neck, chest and upper tail feathers. The rest of the plumage of the purple tiger is black with red under-tail-covers; the rest of the body plumage of the small purple tiger is earth-brown.
Both the small purple tiger and the purple tiger have large and small-beaked morphs , the range of which complements each other like a mosaic. Experimental crossbreeding attempts with the purple tiger have shown, however, that the polymorphism in the beak shape lies on a single gene locus and the allele for large-beakedness is inherited dominantly. Large-beaked and small-beaked morphs of the purple deer use seeds of different hardness as food resources.
Systematics
The taxonomic classification of the purple trilde is still changing. Lesser purple tiger and crimson tiger are occasionally treated as a subspecies of purple tiger.
attitude
Crimson trildes are often offered in stores because of their spectacular plumage. However, they are extremely difficult to keep without it being clear why crimson trildes only survive in the keeping for a short time. Breeding is a big exception, which was first achieved in 1976. Like the crimson tiger, the purple tiger needs an aviary with vertical structures made of bamboo, papyrus or reed, as they tend to overgrow the claws and climbing opportunities promote the natural wear and tear of the claws.
species
The following species are counted among the purpuras:
- Crimson reed ( P. sanguineus )
- Little purple reindeer ( P. minor )
- Purple reed ( P. ostrinus )
