Yellow-bellied Sapsucker

How to find it

Expect only one or two birds, since few make the trip south. Patience and knowing its calls usually pay off, and drumming is often the easiest clue to follow. Look on tree trunks for neat horizontal rows of small round holes, which are sap wells and show that a sapsucker has been there. Because the bird often returns to the same sap-feeding spots, watch a promising tree for a while. Try highland forests and coffee areas first, and keep the light in mind if you want to see the faint yellow belly.

How to recognise it

Despite the name, the yellow belly is faint and easy to miss, and it is best seen in good light. Two marks stand out far more:

- a long white stripe along the folded wing

- a black-and-white face

The white wing stripe is the key mark in every plumage, at rest and in flight.

Males have a red forehead and a red throat. Females have a red forehead but a white throat. Immature birds are dull brown, and the wing stripe still gives them away.

The long, solid white wing patch also helps separate it from Downy and Hairy Woodpeckers.

Behaviour and diet

Sap is only about 20 percent of its diet. It also eats inner bark, insects (especially ants), fruit and seeds. It is generally solitary when feeding, but may join small groups in winter.

In Costa Rica it often returns to the same sap-feeding spots, so it gets easier to watch once you learn its routine. On Turrialba Volcano one bird flew in the bounding style typical of woodpeckers, then spent a long time drilling sap holes in a guarumo tree.

Where it lives

In Costa Rica it tends to be found in the highlands. A park guide says it is most likely at middle and high elevations, especially in forests and coffee-growing areas.

It is also reported from most forested sites in the Caribbean lowlands and foothills, and sapsucker feeding holes were found on a Cecropia trunk in the tropical dry forest of Santa Rosa National Park, Guanacaste. Range-wide, in the nonbreeding season it uses many forest types and semi-open habitats, including pine-oak woodland and orchards.

When to see it

It visits Costa Rica only part of the year, usually from late fall to early spring, with a mountain hotel's page putting its presence at around November to April.

Similar birds

Red-naped Sapsucker has a red nape patch in both sexes, which this species lacks. Its back spots form two rows, while this species has scattered spots. The long, solid white wing patch also separates it from Downy and Hairy Woodpeckers.

Names and lore in Costa Rica

The official Costa Rican Spanish name is Carpintero Bebedor. Other Spanish names listed for the species elsewhere include Carpintero Migratorio and Carpintero de Paso, and Chupasavia Común is the Mexican name.

Status and conservation

The AOCR list marks it as M, a migrant, and the IUCN lists it as Least Concern, with a large range and population.

Photography tips

In the Turrialba record the bird sat high in the tree and was seen only from below, which made the red on the crown hard to judge. Look for a lower perch or a good angle, and remember the yellow belly is best seen in good light. Returning to a known sap tree gives the best chance of a second look.
