Plain Antvireo

How to find it

Look in thick vegetation low in the forest and listen for the mournful, trailing song first. Scan close to the ground and up to about 4 to 5 meters, since it forages there. Check mixed-species flocks and pairs working through the understory. The female's tawny crown is the best mark to watch for in dense leaves. In the Turrialba area, forest near Guayabo National Monument and the Aquiares coffee fields offers the right habitat. At Carara National Park a guide reported it inside the forest, alongside Russet Antshrike.

How to recognise it

This is a small, chunky antbird, about 10 to 13 cm long, with a big head and a short tail.

The male:

- slate-gray above, with a dark gray crown

- two narrow white wing bars

- white throat and upper breast with light gray spots

- yellow center to the belly, pale yellow in Costa Rican birds

The female is the easier one to pick out:

- cinnamon-tawny crown, also described as rufous-tawny

- thin white eye-ring

- olive-brown upperparts, more olive than the male

- more yellow underneath

Behaviour and diet

In Costa Rica it hunts actively, with quick hops and short flights, pausing now and then to scan the surrounding vegetation. It takes beetles, moths, ants, spiders and katydids from leaves and twigs.

Across its range it forages in pairs or with mixed-species flocks, close to the ground, about 4 to 5 meters up.

Both parents incubate the two eggs by day, and in Costa Rica the nesting season runs from February to July. The nest is a thin-walled, deep cup hung from a horizontal fork and decorated with moss, set low in the forest at 0.6 to 2 m.

Where it lives

It lives in the understory of mature forest and the nearby second growth. Across its range it is often common in humid foothill and lower montane forest, mostly below 1,800 m.

In Costa Rica it occurs on both slopes of the northern cordilleras and Talamanca, and on the Caribbean side of the Central Volcanic range, mostly at 700 to 1500 m. It reaches 2,500 m, but only rarely. It is considered uncommon in the Costa Rican lowlands.

Similar birds

Costa Rica has two other antvireos, the Streak-crowned and the Spot-crowned, so check which one you are looking at. The Streak-crowned male has a dark gray crown streaked with grayish-white and a white throat and breast with dark streaks. The Spot-crowned has a spotted crown. The female's tawny crown also looks like that of the Tawny-crowned Greenlet, a small vireo-type bird that also lives in the Turrialba area, so note the crown color.

Names and lore in Costa Rica

In Costa Rica and Nicaragua it is called batarito cabecigrís. In Mexico and Colombia it is hormiguero sencillo, and in Honduras hormiguero cabecigrís.

Status and conservation

The official Costa Rican list marks it R, a year-round resident, and the IUCN lists it as Least Concern.

Photography tips

Mature forest understory and nearby second growth are the places to try, and at Wilson Botanical Garden a tour saw it foraging at eye level. A pair once visited a moth cloth early in the morning at a lodge in the Turrialba region, so a lit sheet can bring this shy bird into view.
