Limpkin

How to find it

Look along oxbows, quiet river backwaters, marsh edges and lake shores where large snails live. Calls at dawn and dusk are often the first clue, so listen first, then scan the likely edges. Where apple snails are present, Limpkins tend to be found. Boat, canoe or kayak trips in the northern wetlands let you drift past sandy banks where other waders live alongside the Limpkin. Check old logs and banks for piles of empty snail shells, since Limpkins bring snails to favorite spots.

How to recognise it

Think of a heron, then adjust.

- Shape: heron-like, but the neck is shorter and thicker.

- Size: about 66 cm long.

- Bill: long, flattened from the sides and slightly curved. Range-wide it is described as yellowish and curving gently downward. The tip often bends slightly right, which helps with a snail's coiled shell.

- Plumage: brown with white spots and streaks, densest on the head and neck.

Costa Rican birds belong to the 'Speckled Limpkin' group, heavily streaked over the head and neck. The darker 'Brown-backed' form lives in South America and central and eastern Panama, and the two may meet in Panama.

Behaviour and diet

Limpkins are alert and solitary in Costa Rica, and they often call loudly once an observer comes into view. They are usually seen alone or in pairs. They walk slowly in search of snails, carry each one to a favorite spot and pick the shell open to eat the flesh. Piles of empty shells around an old log or on a bank show where one has been feeding. It can also feed at night, especially under a bright moon. In Costa Rica it makes clear local movements that follow changes in water levels.

Where it lives

The Limpkin lives in open freshwater marshes, ponds, river edges and sometimes swamps with trees. In Costa Rica it is most numerous, at least in some seasons, in the Tempisque River basin and the Río Frío region. It is local elsewhere in Guanacaste and on the north Caribbean slope, and rare and sporadic in the lowlands of other regions. It reaches 1500 m in the Central Valley. Its range has been growing south along the Pacific lowlands to southern Costa Rica and into Panama since the early 2000s.

When to see it

In Costa Rica it breeds from the middle of the rainy season into the early dry season.

Similar birds

People often take it for a brown heron, but it is not related to herons. It belongs to its own family, Aramidae, which is closest to cranes and rails. Compared with a heron, look for the shorter, thicker neck, the white streaking on the head and neck, and the long curved bill. At a glance it can also pass for an ibis.

Names and lore in Costa Rica

Costa Rican bird listings give three common names: correa, garza morena (brown heron) and carao. The AOCR list uses Carao (Correa). The names show how often people liken it to a heron.

Status and conservation

The AOCR list gives the Limpkin as a resident (R), and it is a resident species in Costa Rica with local movements that follow water levels.

Photography tips

Watch a bird that has caught a snail. It walks up onto dry ground, sets the snail down and shakes the flesh out in a few quick motions, a good moment for a photo or an observation. Calls at dawn and dusk help you find it first.
