The bill of the Clark’s Grebe is bright yellow compared to the yellowish-green bill of the Western.<\/div>\n<\/li>\n
- The black crown of the Western Grebe extends below the eye while it does not in the Clark’s.<\/li>\n
- The Western Grebe\u00a0tends to have less white on the flanks and wings than the Clark’s.<\/li>\n<\/ul>\n
<\/p>\n
The ranges of these two grebe species overlap considerably so they’re often seen together.\u00a0 I thought it might be useful to point out their differences\u00a0since we’re seeing many of them now in much of western North America.<\/p>\n

In fact they’re similar enough that many observers never even recognize Clark’s Grebes when they see them and assume that they’re the more common Western Grebe.<\/p>\n
