Fred,

While the Eared Grebe is known for its congregations of thousands of =
birds (sometimes hundreds of thousands during migration and in winter) =
the Horned Grebe is not. The Horned usually is seen in pairs or small =
locks at most.

If it is between these two species (having ruled out Western and =
Red-necked, I would put my money on Eared.

Tweets,

For the past two days, I have observed a dense flock of grebes
south of Shine near the west end of the Hood Canal bridge.=20
They are just out of scope range=20
to clinch the ID between horned and eared grebe.
It is possible to differentiate these two species on behavioral cues?
The grebes remain in a dense knot of approx. 200 synchronously diving,
hyper-active birds.=20
There is also the typical smattering of horned grebes about the bay
Any thoughts?
