These birds are found around open shorelines, especially in the east and the southeast. Although not known for hanging around Walmart or Target parking lots, they do like other sorts of parking lots and municipal parks. We found them on our way from Brownsville over to South Padre Island.
These two guys who I travel with can identify almost any bird at a glance. They had the laughing Gull pegged right away.
As the photo shows, he was standing right there laughing at how slow I was in establishing his identity.
