PIED-BILLED GREBES: LESS COMMON THAN THE LEAST

PIED-BILLED GREBES: LESS COMMON THAN THE LEAST

There are two grebe species recorded for Abaco. The LEAST GREBE is the most common; the pied-billed grebe (Podilymbus podiceps) is rarer. These small birds, often called dabchicks, are marsh and pond dwellers. They are sometimes found in brackish or even salt water.

The pied-billed grebe is somewhat larger than the least grebe. In the breeding season, they have a distinctive black beak-ring. In the header image, the bird is just starting to acquire the ring. Their dark eyes also distinguish them from the golden-eyed least grebe; and their beaks are pale rather than dark.

These birds have lobes on each toe rather than webbed feet. This helps them to paddle and to dive – which is how they mainly forage. They can stay under water for up to half a minute, often surfacing some distance from the entry point. This is one method they use to avoid danger – especially as they don’t fly with much enthusiasm.

Grebes rather endearingly carry their young on their backs until the chicks are old enough to fend for themselves. The main threat to the species is habitat loss, especially of wetlands. The decline in local populations of this once-prolific bird is such that in some places they classified as threatened or endangered.

The pied-billed grebes’ call has been rendered thus: a “whooping kuk-kuk-cow-cow-cow-cowp-cowp.” If that helps you at all. If not, try this clip:

‘LEAST, BUT NOT LAST’: LEAST GREBES ON ABACO

The Least Grebe Tachybaptus dominicus is an adorable little dabchick that can be very entertaining to watch. These small birds are able to stay underwater for long enough to ensure they always bob up further away from you than you expect. They can easily stay below the surface for 20 seconds, and may dive again only a few seconds after surfacing (their taxonomic name comes from a Greek compound meaning  ‘fast diving’). While underwater, the grebe forages for tiny fish, crustaceans, frogs and aquatic insects. In the breeding season the striped chicks are sometimes carried on a parent’s back.

For the sake of completeness, there is one other dabchick species found on Abaco, the closely related Pied-billed Grebe. Here’s how to tell them apart:  the Least  has a bright golden eye, while the Pied-billed  is slightly the larger of the two species, and has a dark eye and a  black beak-ring in the breeding season.
