Common Yellowthroat

How to find it

Go in with modest expectations, since it is called uncommon in Costa Rica. A Costa Rica winter warbler article advises listening and looking for it in marshy habitats, so start at marsh edges. Stop often to listen for the low, rough call note, which can give the bird away when it stays hidden. Then watch the low tangles for a small, brown bird moving close to the ground. Weedy fields, hedgerows and thickets are worth a check too.

How to recognise it

The male is the easy one. Look for these marks:

A broad black mask, with a pale grey border above it.

A yellow throat.

A brown back.

A whitish belly.

The female has no mask and is much browner than the male. She usually shows a hint of warm yellow at the throat, and that touch of colour often lets you name her.

The whole bird is small, about 11 to 13 cm long and 9 to 10 g, so think of a tiny, compact warbler that vanishes easily into cover. These details describe the species in general, not only Costa Rican birds.

Behaviour and diet

Yellowthroats are furtive and skulk through tangled low vegetation. They glean insects, larvae and spiders from the ground or low growth. In winter they may also eat seeds and fruit.

On the wintering grounds this warbler may join mixed-species flocks but is usually alone, so a lone, secretive bird deep in a thicket is the typical picture.

Where it lives

On the wintering grounds, including Central America, it uses habitats like its breeding ones, with dense vegetation. These include marsh edges, thickets, hedgerows and weedy fields. In migration and winter it is still most common in marshes, though it can turn up in almost any brushy or wooded area.

Autumn migrants spread across Mexico and Central America, including Costa Rica, reaching as far as central Panama.

When to see it

A Costa Rica article lists this warbler among the wintering species to expect when birding in the country during the northern winter months.

Similar birds

Costa Rica also has resident yellowthroats, so check mask and crown pattern. The Olive-crowned Yellowthroat (resident, R) is common in wet pastures and marshy habitats. The Gray-crowned Yellowthroat is common in pastures and weedy fields. The Mourning Warbler, a migrant, is another Geothlypis species on the Costa Rican list.

Names and lore in Costa Rica

Costa Rica uses the name Antifacito Norteño. Other countries use different Spanish names: Caretica in Cuba, Cuelliamarillo común in Honduras, Enmascarado norteño in Nicaragua and Antifacito común in Panama. Elsewhere it is often Mascarita común or Mascarita norteña, so field guides from other countries may list it differently.

Status and conservation

The official Costa Rican list marks it as a migrant (M), and the IUCN rates the species Least Concern, with about 77 million mature birds estimated.

Photography tips

Yellowthroats forage low to the ground in dense undergrowth, so aim low. In garden settings, both sexes have been photographed in low shrubs, and females have also been photographed at feeders.
