1st Round Votes (4 III/3 IV-A)
- Al Guarente –ย Class III -Comments:ย ย Description was right on. I have to accept this sighting.
- Dave DeReamus –ย Class III –ย Comments:ย I believe the description is good enough to accept this identification.
- ย Tom Johnson – Classย III –ย Comments:ย This seems like a very good description of Western Grebe despite its rarity in Pennsylvania.ย This is an accept vote based on the documentation โ Iโm not familiar with the observer โ if anyone has reservations, Iโd be happy to discuss the record.
- Geoff Malosh –ย Classย III –ย Comments:ย I am willing to accept this as Aechmophorus sp., as the description touches on all of the key points for this group, including an indication of the birdโs size. However there is not enough detail/discussion to eliminate Clarkโs Grebe. The key point on the coloration around the eye is stated simply as โthe black on top of the head went down just past the eyeโ. For an Aechmophorus in non-breeding plumage I believe a more critical examination of the lores is key, and this is absent from the discussion.
- Ramsay Koury –ย Vote:ย Class IV-A –ย Discussion:ย ย This is an interesting sighting.ย I feel the observer likely had a Western Grebe, but I am not sure she completely ruled out a Clark’s Grebe.
- Ben Coulter –ย Classย IV-A –ย Comments:ย Based on the description, I cannot conclusively rule out Clarkโs Grebe.ย The description (which could have been lifted from a field guide) is suggestive of Aechmophorus sp.ย I am troubled by the observerโs admission that she was looking through the book instead of watching the bird.
- Drew Weber –ย Class IV-A –ย Comments: This may be a good record but I feel that there should be mention of Double-crested Cormorant, with a juvenile cormorant possibly being the bird most people would mistake for an Aechmophorus grebe.
