Great Grebe vs Red-necked Grebe

Great Grebe

Podiceps major

Huge1.6 kgWetland

This is a very large grebe, with proportions more like a goose or a cormorant than a typical grebe. They range in length from 67 to 80 cm (26.5 to 31.5 in) and usually weigh about 1,600 grams (3.5 pounds), but can scale to at least 2 kg (4.4 lb). They are buffy-rufous on the neck and chest, blackish on the back and have a whitish belly. The head is sooty gray with a reddish-brown eye. Due to its size and unique coloration, the great grebe is unlikely to be confused with any other bird, including other grebes.

Red-necked Grebe

Podiceps grisegena

Large1.0 kgWetland

The red-necked grebe is a medium-large grebe, smaller than the great crested grebe of Eurasia, and the western and Clark's grebes of North America, but noticeably larger than other northern grebe species. In breeding plumage, it has a black cap that extends below the eye, very pale grey cheeks and throat, a rusty red neck, dark grey back and flanks, and white underparts. The eyes are dark brown and the long, pointed bill is black with a yellow base.
