First off, congrats and thanks to Kyle Carlsen and Mollee Brown for a great find and getting the word out quickly this morning!. I think this has to be the first Laughing Gull in the state in at least a decade (or my memory could be pretty bad).
The chief news is the Laughing Gull is still around and was loafing on the water on Tygart Lake out from Doe Run, just a little while a go when I left. Here is what I have been able to piece together about the bird so far, so that it may benefit those who try to chase tomorrow.
The bird spent a large portion of the day hanging out and being fed by the boaters who were in the Cove Run area of Tygart today. Joe Hildreth may correct me if I am wrong, but I don't think this area is feasibly bird-able except by boat. The bird made at least two appearances off of the Doe Run area late this morning/early afternoon where Steve Wilson was kind enough to report it. The bird was seen briefly this evening at the marina (by me) before it took off and headed south back toward the Doe Run area. I caught up with the bird again by continuing south past the nature center to the cabins/cottages area where this is (kind of) a trail that heads down to the water and allows you to look across the lake toward Doe Run. The possible advantage of this spot is that if the bird is loafing close to shore near Doe Run but to the north you would be able to see it pretty easily. This would be difficult (impossible) to see from the Boat Launch area unless you crossed the Doe Run dam and even then, it could be tough to spot. The disadvantage would be you are further away. You of course would not be able to see the bird from that vantage point if it was actually in the Doe Run impoundment. It is also a much shorter drive from the marina area.
Anyway, I am surprised the bird is still hanging out based on previous gull experiences in the state. I hope others get to take advantage. Also, as a note of common sense, respect the other people who are using the boat launches, marinas, and cabins. Boat traffic should be decreased tomorrow by a good margin so maybe this will make the bird easier to spot. Not sure where the bird is roosting, but patterns and deduction would suggest either one of the coves near Pleasant Creek or the Marina area. Hope this all helps. Sorry for the length
