Northern Parula
Northern Parula: Small, compact warbler with blue-gray upperparts and bronze-green back patch. Throat and breast are yellow, breast band is chestnut-brown and black, belly and undertail coverts are white. White eye-ring is broken. Wings are blue-gray with two white bars. Tail is noticeably short.
● Song:
Insectlike buzzy trill of zeeeee-yip, which rises and trips over the top.
● Foraging & Feeding:
Northern Parula: Feeds on spiders, caterpillars, beetles, moths, ants, wasps, bees, flies, locusts, scale insects, plant lice, lacewings, and mayflies. Commonly gleans tips of foliage, small twigs, and branches high in the canopy; occasionally hovers or hangs upside-down on foliage, and sallies for aerial insects.
● Breeding & nesting:
Northern Parula: Three to seven white eggs with brown flecks and splotches are laid in a basket-shaped nest woven from grass, bark, and vegetable fibers, and neatly hidden in Spanish moss in the south or in beard moss or Usnea lichens in the north. Incubation ranges from 12 to 14 days and is carried out by the female.
