Visual Identification
Pied-billed Grebe
Appearance
The Pied-billed Grebe is a small, chunky waterbird with a distinctive thick, compressed bill. Its plumage is primarily brown and grey, with white underneath and on the undertail. During the breeding season, the bill develops a black ring, and the throat becomes black, giving the bird its name.
In winter, the plumage becomes duller brown, and the black ring on the bill typically fades. Juveniles resemble non-breeding adults but often have striped faces and necks, with an orange-reddish bill instead of the adult's bluish-white.

Distribution
Pied-billed Grebes inhabit a wide range of freshwater habitats, including ponds, lakes, marshes, and slow-moving rivers. They prefer areas with dense aquatic vegetation for cover and nesting. These birds are found across much of North and South America.
In the United States, they are year-round residents in many southern states and along the coasts. Northern populations migrate south for winter, while some birds in temperate regions may stay if water remains open.

Diet
Pied-billed Grebes are opportunistic feeders, primarily consuming small fish, aquatic insects, and crustaceans. They use their strong bill to crush hard-shelled prey like crayfish.
These birds often dive to catch food, sometimes staying submerged for up to 30 seconds.
Behaviour
Pied-billed Grebes are excellent swimmers and divers, often submerging quietly rather than flying when disturbed. They have the unique ability to control their buoyancy, sometimes floating with only their head above water.
These birds are generally solitary or found in pairs, rarely forming large flocks.
Vocalisation
The Pied-billed Grebe has a distinctive vocalization, often described as a series of cow-like notes: 'cow-cow-cow-cow-cow-cow-cow'.
During the breeding season, they also produce a loud, descending 'whoop, whoop, whoop' call. In alarm, they emit a sharp 'kek-kek-kek' sound.
Nesting & Breeding
Breeding season for Pied-billed Grebes typically occurs from spring to early summer. Pairs form monogamous bonds and engage in courtship displays, including synchronized diving and platform-building.
Nests are floating platforms of aquatic vegetation anchored to standing plants. Females lay 2-10 pale blue eggs, which become stained brown over time. Both parents take turns incubating the eggs.
Incubation lasts about 23 days. Chicks are precocial, able to swim shortly after hatching, but often ride on their parents' backs for protection. They fledge at 3-4 weeks but may be fed by parents for up to 10 weeks.
Lifespan
The Pied-billed Grebe typically lives for 3 to 5 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Conservation and Status
Global Conservation Status
While the Pied-billed Grebe is currently listed as Least Concern, it faces threats from habitat loss due to wetland drainage and pollution. Climate change may also impact its breeding habitats.
Conservation efforts focus on protecting and restoring wetland ecosystems.
Birdwatching Tips
- Look for them in freshwater ponds, lakes, and slow-moving rivers
- Listen for their distinctive 'cow-cow-cow-cow-cow-cow-cow' call
- Observe early morning or late evening when they're most active
- Watch for their sudden disappearances as they dive underwater
- In the US, they're year-round residents in many southern states

Did You Know?
- Pied-billed Grebes can trap water in their feathers to control buoyancy, sinking lower in the water when threatened.
- They often eat their own feathers and feed them to their young, possibly to protect their digestive tracts from sharp fish bones.
- Despite being excellent swimmers, their feet are placed far back on their bodies, making them awkward on land.
