Rufescent Tiger-Heron

How to find it

Start in the Caribbean lowlands, where it is most often reported. Early morning boat trips along rivers or mangroves are suggested as the best way to find it. Scan the shaded edges from the boat, where vegetation hangs over the bank. Look for still birds at the water's edge in shade, on partly sunk logs and under overhanging plants. Slow forest streams and backwater swamps are classic habitat. Listen at dawn and dusk for the deep 'ooom' carrying through the forest.

How to recognise it

Adults have a head, neck and upper chest of chestnut barred with black. A brown stripe edged in white runs down the throat and the middle of the neck. The face skin is yellow.

It is a medium to large heron, about 66 to 76 cm long across its range. It has a bittern-like look, with a wide neck, heavy bill and short stubby tail.

Immatures look quite different. The head is reddish, and the neck and upperparts are warm buff to light rusty, broadly barred with black. A white stripe runs down the front of the throat and neck and the middle of the belly.

Young birds take at least two years to reach adult plumage. Subadults look like adults but have wider, heavier barring.

Behaviour and diet

It is usually solitary and often stands hunched at the water's edge for long periods, waiting for prey. It tends to follow small streams in deep forest and is often active at night.

In Costa Rica it feeds mainly on fish 5 to 20 cm long, such as cichlids, characins and catfish. Expect a bird that holds still and leaves the searching to you. One Costa Rican birder likens it to a grandaddy giant Green Heron.

Where it lives

In Costa Rica it lives from sea level up to about 1,200 m, but most records are below 500 m. The National Museum heron catalogue lists it as a resident at 0 to 500 m. It occurs on both the Caribbean and Pacific slopes.

One Costa Rican writer calls it a Caribbean lowland species that rarely occurs above 300 m and is usually not found on the far side of the mountains. A Spanish-language site calls it an uncommon to fairly rare resident on the Caribbean slope. It needs forested wetland and prefers vegetation that hangs over the bank of a lowland river, lagoon or marsh.

When to see it

Nesting is said to run from May to October in Costa Rica, with the most activity from June to August. The National Museum catalogue gives the rainy season as its breeding period.

Similar birds

The Bare-throated Tiger-Heron is the common lowland tiger-heron in Costa Rica and the one seen easily at many wetlands. Adult Rufescent has a rufous chestnut head and neck, not a black head and brown neck. The Fasciated Tiger-Heron is the one of rushing rivers. It is smaller than the Rufescent, has a grey neck as an adult and lacks the yellow throat. Immature tiger-herons are often best left unidentified, though a more rufous head and neck points to Rufescent.

Names and lore in Costa Rica

The Spanish name on the AOCR list is Garza-Tigre de Selva. Other Costa Rican common names are Martín Peña and Pájaro Vaco. In Tortuguero, a tour operator says locals simply call the tiger-herons Garza Tigre, a name that may cover more than one species.

Status and conservation

It is a resident (R) on the AOCR list and is listed as Least Concern, with Costa Rican populations appearing healthy where suitable habitat remains.
