Northern Parula

How to find it

Start by listening for the buzzy trill, since parulas sing a lot on migration. Then check mixed flocks of warblers, where this tiny bird can hide among others. During migration it feeds lower in the forest than on its breeding grounds, so scan at eye level as well as overhead. Whenever you find a parula, check the eye and the chest first, because the resident Tropical Parula is far more likely.

How to recognise it

Look for these marks:

Upperparts mostly blue-gray, with a greenish patch on the back.

Two white wing bars.

A yellowish breast fading into a white belly.

Breeding males add bluish and rusty bands across the breast and bold white crescents around the eyes. Females are duller and usually lack the breast bands.

This is one of the smallest migratory warblers, about 11 to 12 cm long and weighing 5 to 11 g. It is often among the tiniest birds in a mixed flock, so look for the smallest shape moving through the leaves. These details describe the species in general.

Behaviour and diet

It hops quickly along branches and picks spiders and insects from leaves and twig tips. On migration and in winter it joins mixed-species flocks with other warblers, so a flock of small birds is the place to look. On its breeding grounds it stays mostly in the canopy, but during migration it also feeds lower in the forest, which is easier on the neck.

Where it lives

Outside the breeding season it uses many habitats, including shrubby pastures, moist or dry forest, and farmland or plantations. The species breeds in eastern North America and winters mainly in Mexico, northern Central America and the Caribbean. Costa Rica lies at or beyond the southern edge of that usual winter range, which is why records here are unusual.

Similar birds

The Tropical Parula, a Costa Rican resident, is the bird most often mixed up with this one. The Northern has white arcs around the eye, a dark chestnut band across the chest and less yellow below. Tropical Parula males have a black face mask and an orange wash on the throat and upper breast. A birder in Costa Rica notes that local Tropical Parulas show only one short wing bar, while the Northern shows two clear ones. Dull young Tropical Parulas and rare hybrids can look very much like a Northern.

Names and lore in Costa Rica

The name used in Costa Rica is Parula Norteña. Other Spanish names used elsewhere include Reinita Norteña, Cigüita Parula, Chipe Pecho Manchado, Parula de Pecho Dorado and Reinita Pechidorada.

Status and conservation

Listed as M (migrant) on the AOCR list, though in Costa Rica it is recorded as a vagrant during the northern winter rather than a regular wintering bird.

Photography tips

On migration this parula often feeds lower in the forest than on its breeding grounds, which makes it easier to see and photograph without craning your neck.
