Observations

  1. Number observed: 30

    Details: flyby out over lake toward Somers Point

  2. Number observed: 6
  3. Number observed: 5

    Details: mixed flock of large pale grey grebes, but today closer to our vantage and with better light and calm lake surface. the Clark's grebes showed narrower dark line on dorsal surface of neck than for the western grebes. also the general dorsal surface paler grey for Clark's than for western. the flanks of the Clark's were routinely paler than the flanks of western grebes, and certainly flashed white more brilliantly as the birds moved on the water, emerged to the surface following dives, and preened. the dark cap margin at or above the eye was more difficult to determine, but appeared above the eye for all the grebes otherwise noted as Clark's and to include the eye on those birds otherwise categorized as western grebes. bill color was not distinctive at this distance and all birds appeared to have similar bills. we have been watching this dynamic flock of large pale grebes for several days and believe this is our best set of distinctions between the two species.

    later in the season we saw grebes closer to shore, but that entry awaits.
