American Dipper

How to find it

Scan boulders and fallen logs along whitewater streams, and watch for birds flying low over the water. In San Gerardo de Dota, the La Catarata trail follows the Savegre River and is a good spot for both Torrent Tyrannulet and American Dipper. One group went down to the river in late afternoon, from about 4pm, made the dipper its target and saw two. One tour spends an extra morning walking the waterfalls road, with some luck needed. Because pairs keep to one stretch of river, a bird seen once is worth looking for again in the same place.

How to recognise it

Look for a slate-gray songbird with white eyelids and a stubby tail. It is medium-sized, about 18 cm long, and chunky rather than slim.

The giveaway is the constant bobbing motion. It flits among midstream rocks and logs, then vanishes underwater to feed.

It perches on exposed rocks, bobbing up and down and wagging its tail, which makes it easier to pick out. White-splashed midstream rocks and mossy nests under bridges show that dippers are around.

Behaviour and diet

The dipper dives and swims in fast streams, using its wings underwater to hunt aquatic insects and small fish. A Costa Rican birder watched one stay under for several seconds at a time.

Between dives it flies low over the water and rarely goes far from the stream. Pairs defend a long, narrow territory along a stream for most of the year, which explains why the same stretch of river often holds the same birds.

Where it lives

The dipper lives along fast, clear, cold mountain streams and favors steep streams with boulders and waterfalls. It nests on cliffs or behind waterfalls beside streams. It needs clean, well-oxygenated water.

In Costa Rica it occurs on the Caribbean slope and on both slopes of the Talamanca range, from roughly 800 to 2500 m. After breeding, some birds drop as low as about 600 m. On the Pacific side of the Central Volcanic Range it occurs only above about 1700 m.

When to see it

Costa Rican natural history notes say the dipper breeds from February to May, which is the nesting season.

Similar birds

Torrent Tyrannulet shares the same Savegre streams and a tail-bobbing habit. It is a small flycatcher whose call is a sharp chip or seek. The dipper is a chunky, short-tailed songbird with a burbling song, so size, shape and voice separate the two.

Names and lore in Costa Rica

The Costa Rican Spanish name is Mirlo Acuático Plomizo. An English alternative name is water ouzel.

Status and conservation

The AOCR list marks it as a resident (R), and it is rated Least Concern globally by the IUCN.

Photography tips

Look for it on exposed rocks, where it bobs and wags its tail. At Tapantí one bird foraged only a few meters from the observers, which allowed close views and photos, and one shot caught it about to dive again.
