What is "wilsonia"

Wilsonia is a small genus of New World warblers which breed in North America. They are migratory, wintering south of their breeding ranges in Central America, the West Indies or South America.

The three species are:

• Hooded warbler, Wilsonia citrina
• Wilson's warbler, Wilsonia pusilla
• Canada warbler, Wilsonia canadensis

The hooded warbler is now included in Setophaga, while Wilson's and Canada are included in Cardellina.

Wilsonia warblers are 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.

Wilsonia is a genus of perennial subshrubs in the family Convolvulaceae. The genus is endemic to Australia, occurring in coastal saltmarshes and also occasionally in inland saline areas.

The genus was first formally described in 1810 by Robert Brown in Prodromus Florae Novae Hollandiae. The name honours John Wilson, author of A Synopsis of British Plants.

• Wilsonia backhousei Hook.f. - Narrow-leaf Wilsonia
• Wilsonia humilis R.Br. - Silky Wilsonia
• Wilsonia ovalifolia Hook.
• Wilsonia rotundifolia (Benth.) Summerh. - Round-leaf Wilsonia
