Clark's Grebe

Discussion thread for Clark's Grebe. If you would like to add a comment, click the Post Reply button.

------------

BNA Online lists subspecies "transitionalis" as the "Northern race", but Clements indicates that nominate "clarkii" is the northern species: "W North America (se Alaska to n Mexico)" vs. "transitionalis": Coastal w Mexico (Nayarit) and Mexican plateau

Anyone have any other sources? The species wasn't split when Howell & Webb was published, even though they indicated a split was imminent and have a separate account for it.

We still have two contradicting sources and one confused editor here.
