"Ergaticus" is a genus of New World warblers endemic to Mexico and Guatemala.

The species are:
* Red Warbler, "E. ruber"
* Pink-headed Warbler, "E. versicolor"

They live in forests at altitudes of 1800 to 3500 m, the Red Warbler to the west of the Isthmus of Tehuantepec and the Pink-headed Warbler to the east (Howell and Webb 1995).

Both are average-sized for warblers (12.7 to 13.5 cm or 5 to 5.3 in long). Adult plumage is largely red and pink; juvenile plumage is largely "pinkish cinnamon-brown" (Howell and Webb 1995). The bill is small and narrow at the base even for a New World warbler. The tail is rounded and relatively long (Ridgway 1902). The songs consist of high-pitched chips and short trills (Howell and Webb 1995).

They occur singly or in pairs and may join mixed-species feeding flocks (Howell and Webb 1995).

The nest is shaped like an old-fashioned oven with an opening to the top or side, made of pine needles, grass, or similar materials. It is placed on the ground or on a bank. Both can lay 3 or 4 eggs; the Pink-headed Warbler sometimes lays only 2. The eggs are off-white with reddish-brown and gray speckles (Howell and Webb 1995).

The name is from Ancient Greek "ergatikos", "willing or able to work" (Jaeger 1978).
