The LAPWING (269. Vanellus vanellus) is an Old- World species of acci- 

 dental occurrence in America. The only record for eastern North America 

 south of Greenland is based on a specimen shot at Merrick, L. I., in Decem- 

 ber, 1883 (Dutcher, Auk, iii, 1886, p. 438).

The following notes are abridged from Mr. Mackay's extended ac- 

 count of the habits of this species (Auk, ix, 1892, pp. 143-152). They 

 are in a great degree tide birds, and seek a large part of their food on 

 sand-flats left by the receding water. As the tide rises they resort to 

 adjoining marshes or uplands, beaches, or the exposed crests of sand- 

 bars. In migrating they fly in lines and also in ranks, like Ducks and 

 Geese. When on the ground they usually run very fast for four or five 

 yards, then stop, elevate the head, and look around. They strike at 

 the object they are going to pick up and eat with a very quick motion. 

 They have two calls : one of several notes, with the accent on the sec- 

 ond one, is mellow, clear, and far reaching ; the other is low, and is 

 uttered when they are at ease and contented.
