The large Whistling Plover, or Bull and Beetle-head Plover as it is called in its autumnal 

 dress, appears with us from the south in May, ranging from 26° to 70° north. It breeds 

 from Pennsylvania northwardly. It lays four cream-colored eggs, spotted and blotched with 

 light brown. Feeds on insects and berries. It passes through Long island in September, on 

 its way southwardly. It is common to Europe and America. Is closely allied to the Lap- 

 wing of Europe.
