Arizona may seem an unlikely home for a family of sleek, aquatic diving birds, but its network of ponds, marshes and reservoirs supports five species of grebes—small- to medium-sized freshwater birds (family Podicipedidae) noted for their lobed toes, slender necks and the dramatic courtship displays of some. Although grebes spend most of their time submerged, Arizona birders encounter them both year-round and in high densities during migration and wintering periods.
Pied-billed Grebe (Podilymbus podiceps)
A true generalist, the Pied-billed Grebe is the most widespread grebe in Arizona. Found year-round on ponds, marshes and quiet backwaters from the low deserts into montane valleys, it frequents cattail-choked sloughs and farm ponds alike. Their distinctive, compact shape and chunky bill make them easier to spot than most grebes, and they nest in floating platforms of vegetation in sheltered bays.
Eared Grebe (Podiceps nigricollis)
Arizona’s signature grebe is the Eared Grebe, which stages by the tens of thousands at saline and alkaline lakes such as Montezuma Well, Saguaro Lake and the Hassayampa River Valley each autumn. After a spectacular molt into dramatic black-and-chestnut winter plumage, many remain through the winter on low-elevation reservoirs and even on large golf-course lakes. Their gregarious winter flocks and striking red eyes make them a favorite among winter birders.
Least grebe (Tachybaptus dominicus)
Arizona’s first confirmed records date back to 16–23 December 1976, when a lone individual was observed at Guevavi Ranch in Santa Cruz County. Since then, additional sightings have been documented at a handful of wetland sites—including the Avra Valley wastewater-treatment plant, Gilbert Water Ranch, Glendale Recharge Ponds, Willow Tank near Portal, and areas along the lower Colorado River—with at least four individuals reported between 2021 and 2023 alone.
Western and Clark’s Grebes (Aechmophorus occidentalis and A. clarkii)
Once lumped as the “Western Grebe,” these two tall, elegant species breed sparingly on high-elevation lakes in northern Arizona—places like Mormon Lake, Big Lake and the Mogollon Rim region. During migration and winter they disperse to larger reservoirs such as Roosevelt, Bartlett and Apache Lakes, where they can be seen in loose rafts. Their long, slender necks and distinctive “racing” courtship dances are best appreciated in spring and early summer at remote mountain waters.
Horned Grebe (Podiceps auritus)
A less common visitor, the Horned Grebe winters in Arizona’s wetlands and reservoirs, often mixed in with flocks of Eared Grebes. In its adult winter plumage it shows cream-colored cheeks and bold “horns” of black plumage. Sightings peak from November through February, primarily on larger, open-water sites.

Red-necked Grebe (Podiceps grisegena)
An accidental or very rare winter visitor, the Red-necked Grebe turns up only occasionally—typically on large reservoirs—often prompting excited reports when it appears. More slender and longer-necked than the Pied-billed, it displays fine white neck stripes and a subtle rosy wash in breeding plumage. (no photographs yet).
