Yesterday between 5:30 & 6:30 pm I saw the adult Black-headed Gull at South Amboy/Morgan mud flats. It was foraging with up to 80 Bonaparte's Gulls and a couple Laughing & Ring-billed Gulls not too far off shore. In good light, I could see the dark hood, black under the primaries, white upper wing wedge, and larger size than the Bonaparte's. I had good scope views for about an hour. They never came into the beach the whole time I was there. I started around 4 pm.
2 pairs of Oystercathers were there and 50+ Horned Grebes. A few Great Cormorants were on a rock pile/channel marker to the north of the park.
