Hi all,
Doug is correct that the last confirmed sighting of a Red-necked Grebe
in deep-water-challenged Benton County was in 2003. Here is an excerpt
from my Audubon field notes for that period:
A Red-necked Grebe that showed up at the Knoll Terrace s.p. 14
Oct was a rare bird for Benton Co. (Randy Moore). It appeared to
be a juvenile in transition plumage, and stayed at least through
19 Oct (J Simmons; P Vanderheul). On 27 Oct one was at Big Lake
and two were at Foster Res. (R Campbell); the two at Foster Res.
were still there 28 Oct (J Fleischer & M Nikas).
As I recall, the observers were not able to conclusively rule out
Holböl's Grebe.
There was also a possible sighting at the same sewage ponds in late
August of 2006. Here is the description by Paula Vanderheul:
I viewed 2 grebes for a long time watching a dark one with
varied colored facial mask like. It was exercising its wings and
moving around most of the time. At first I thought it to be a
pied-billed grebe. The other was floating near it not moving
much. Its face was more grayish with a bit of white at throat
and longer dark neck. The bill was large, and the head was
large. They were out in the middle and I only had my 8 X 42
ranger eagle optics. I suspect they both were RED-NECKED GREBE.
Being an adult and juvenile.
There have been considerably more frequent sightings from Linn County,
in the August-November window and especially in late October.
Good birding,
Joel
