|Red-faced Warbler (Cardellina rubifrons)|
|Clade:||Blackbird and warbler group|
Cardellina is a genus of birds of the New World warbler family Parulidae. Most classification systems list at least five species., however the South American Classification Committee of the AOU continue to list Wilson's warbler and Canada warbler in the genus Wilsonia.
Recent genetic research has however suggested that the type species of Wilsonia (Hooded Warbler W. citrina) and of Setophaga (American Redstart S. ruticilla) are closely related and should be merged into the same genus. As the name Setophaga (published in 1827) takes priority over Wilsonia (published in 1838), Hooded Warbler would then be transferred as Setophaga citrina. Where this is accepted, the other two Wilsonia species are then transferred to their next-most closely related genus, Cardellina. This change has been accepted by the AOU, but has not yet been taken up by the IOC.
List of species
- Red-faced Warbler – Cardellina rubrifrons
- Red Warbler – Cardellina rubra
- Pink-headed Warbler – Cardellina versicolor
- Wilson's Warbler – Cardellina pusilla
- Canada Warbler – Cardellina canadensis
The former Wilsonia breed in North America. They are migratory, wintering south of their breeding ranges in Central America, the West Indies or South America. Wilsonia warblers are 12–13 centimetres (4.7–5.1 in) long. They have yellow underparts and black head markings in at least the adult male plumage. Two species have plain olive green-brown back, but the Canada Warbler has grey upperparts and is also migrates much further than the other species in the genus.
The breeding habitat is broadleaved woodlands with dense undergrowth. These birds nest low in a bush or on the ground, laying 3–6 eggs in a cup nest.
Wilsonia warblers feed on insects, often caught by flycatching, and they have distinctive songs and loud chip calls.
