Red-throated loon seems ruled out by shape of bill. 2. In fact all loons & W. Grebe seem ruled out by bicolored bill. 3. Posture & Build were slimmer than most loons I've seen. 4. Neck which definitely was grey (in past) all the way around in front also seems to rule out there. I am puzzled by 2 things & although I'm sure it is a RN Grebe I wonder if it is in some intermediate plummage [sic]. 1 White patch at waterline in front. I saw this distinctly & sketched it on 11/9 as well as on a brief look at the bird on 11/16. 2 Dark cap seems to extend farther down the head than any of the plates would lead me to expect. \| The original documentation form event lasted from 07:45:00/08:15:00.
