The Laugliing Gulls select islands in the salt meadows or grassy 

 patches where the water is never very deep, and here, just above high- 

 water mark, their bulky nests of grass, sea weed, etc., are placed. As 

 we approach a colony, the few birds that are always flying about are 

 joined by others that have been sitting on the nests, until, as we land, 

 the whole air is full of flapping wings and the harsh, unearthly laugli-

 the danger of their eggs or young. 



We have no handsomer bird on our coasts than this beautiful gray 

 and white Gull, with its slaty hood and faint flush of pink on its 

 breast, which seems to leave the feathers soon after the bird has been 

 killed. 



Formerly an abundant summer resident on the salt meadows along 

 the coast; it is now restricted to two colonies, one at Brigantine and 

 the other on Gull Island, Hereford Inlet, both under the protection of 

 the National Association of Audubon Societies. The birds arrive 

 April 4th to 20th, and have mostly departed by October 1st. The first 

 sets of eggs are laid in May. 



In late summer they are often found in immense flocks on lower 

 Delaware Bay, and in spring and fall occasional individuals come up 

 to Philadelphia or further. Two were taken opposite Bristol October 

 23d, 1895; one at Fish House, autumn, 1901, and another on Timber 

 Creek, November 7th, 1896. 



In the colony at Brigantine, Mr. I. N. DeHaven and I found a few 

 birds (apparently barren) in immature plumage with the breeding
