Black head/hood. Prominent eye-arcs oriented to the rear-side of eye. Reddish or at least partly red (and blackish) bill, slightly drooped. Dark mantle. White below. I did not detect any faint rosy wash below, but didn t get a good frontal view. |

Similar
species and
how were they eliminated: |
Franklin's Gull has LARGE, conspicuous white spots spaced along dark
flight feathers. Otherwise very similar. Bonaparte's Gull is way smaller/daintier and lacks eye arcs and wing spots. Little Gull: ditto Sabine's Gull: ditto, and has medium-large wing spots Black-headed Gull has paler mantle, browner head and less conspicuous eye arcs |
Previous
experience with this & similar species: |
I found an immature Laughing Gull almost exactly a year ago at Sand
Hollow SP. My tour group found an adult vagrant at Tokeland (SE WA) August 2023. I have seen many on the East
Coast, most recently in April on the beaches near Cape Canaveral. I have observed and distinguished many Franklin's and Bonaparte's Gulls at Sand Hollow over the last two years. Years ago I observed many European black-headed type gulls. |

Additional comments: | I was hopeful for some good birds the morning following a major wind and lightening event. At the conclusion of my routine (and very successful) "rounds" at SHSP I made one last check of the boat launch overlook, expecting to see the grebe flock closer than they were 5 hours earlier, as is their pattern. I was scoping the flock and stumbled upon this gull which I would have otherwise overlooked as just another gray-and-white grebe-blob in the group. I paid it particular attention in order to determine whether it was a Bonaparte s or Franklin s, both of which would be flagged by eBird. The more I looked the more I wondered about the ID, with Laughing Gull somewhere in the list of options. I focused particularly on the small/narrow white spots (more like vertical lines) spaced along the dark flight feathers. (I was able to zoom in to practically fill the entire field of view.) Decided I better check in with Sibley. That s when I determined this was a Laughing Gull. I grabbed my camera-phone but by this time the bird had disappeared. Over the next 20 minutes it did not return. I did not attempt to relocate it along the shorelines (solely to attempt a photo) because they were all overrun with recreationists. I immediately notified the local rare bird text group with brief description. |
