#5 Red-faced Warbler vs #12 Hooded Warbler

Red-faced Warbler

  • Both sexes are known to attempt to attract a mate during the breeding season.

  • In one study, over 45% of the nests contained young that had no genetic link to the apparent breeding male. This means that the female had copulated with more than one male.

  • Red-faced Warblers are highly sensitive to environmental changes especially logging. Logging tends to cause huge decreases in the number of individuals present or cause their complete disappearance from and area.

  • They are known to flick their tails from side to side while feeding.

  • The Red-faced Warbler is the only North American warbler with both a bright red face and upper breast.

Hooded Warbler

  • Unlike many other warbler species, Hooded Warblers are highly territorial on their wintering grounds.

  • Males and females frequent different habitats while on their wintering grounds. Males prefer mature forests while females are attracted to scrubbier forests and seasonally flooded areas.

  • The last part of the Hooded Warbler's scientific name, citrina, refers to its bright yellow color.

  • Hooded Warblers can be difficult to find during the breeding season because they prefer the dense understory of shrubs and heavy vegetation.

  • Other than their hood, another field mark to look for is their white outer tail feathers. These are highly noticeable when the Hooded Warbler is is flicking or fanning their tail.
