Streak-crowned Antvireo

How to find it

Look for mixed flocks of insect-eaters in the forest understory and scan them slowly, since this bird is quiet and easy to overlook. Concentrate on low to mid levels, because it usually feeds about 5 to 25 feet above the ground. Learning the song and the soft whistles will help you pick it out. Tirimbina is a place where birders check these understory flocks for it. It can come in close yet be hard to spot in poor light, and it may not stay long.

How to recognise it

The male is the easier one to name. He has a dark gray crown streaked grayish-white, a white throat and breast with dark streaks, and yellowish underparts.

The female looks quite different. She has a rufous crown with dark spots, and an ocher breast and flanks. A warm, rufous-capped antvireo in a flock is her pattern.

Because the two sexes differ so much, it helps to fix both in mind before you step into the forest: the streaked gray cap and streaked white breast of the male, and the spotted rufous cap of the female. The bold streaks on the male's crown and breast are also what separate him from the similar Plain Antvireo.

Behaviour and diet

This is a slow, deliberate forager. It hops through foliage, stopping to scan, and sometimes makes a short sally to the underside of a leaf to grab prey. It also hover-gleans, picking prey from leaves while hovering.

It eats mostly insects, and also other arthropods such as spiders. It feeds alone or in pairs, and it is most often seen as part of mixed-species flocks that can include woodcreepers, antwrens and greenlets.

Where it lives

It lives in the understory and mid-story of lowland and foothill evergreen forest. In Costa Rica and Nicaragua it ranges from sea level up to about 800 m (2,600 ft).

In Costa Rica it lives on the Caribbean slope through most of the country, and it also occurs across northern Costa Rica into Guanacaste Province. Records come from the Arenal volcano area in Alajuela, Braulio Carrillo National Park and Tirimbina Rainforest Center in Heredia.

When to see it

In Costa Rica it breeds between March and June.

Similar birds

Plain Antvireo is the Costa Rican lookalike, but the Streak-crowned male has bold streaks on the crown and breast that Plain lacks. Spot-crowned Antvireo is slightly larger and overlaps little with this species. Tell them apart by voice, by the stronger dusky streaks on this bird's breast, and by crown pattern. The Spot-crowned song is higher and faster.

Names and lore in Costa Rica

In Costa Rica and Nicaragua the common Spanish name is batarito pechirrayado. In Honduras and Nicaragua it is also called choquita de corona rayada or hormiguerito pechirrayado.

Status and conservation

The AOCR list marks it as a resident species endemic to the region (R-END), and the IUCN rates it Least Concern.

Photography tips

Aim for the understory flocks and keep your camera ready at low to mid levels. Light under the canopy can be poor, and one tour found the male hard to spot for that reason, so a patient approach helps.
