ANNOTATED LIST OF THE BIRDS 153 



sembles other species of the genus, and is doubtless over- 

 looked, as it is exceedingly difficult to distinguish in life, and 

 this can only be done by those who are thoroughly familiar 

 with the exact pattern of coloration of the Pectoral and 

 White-rumped Sandpipers, and who could describe all three 

 from memory in detail. Above Baird's and the White- 

 rumped are practically identical, but Baird's has fuscous 

 instead of white upper tail coverts. The Pectoral is browner 

 than either with blackish tail coverts. Below all three species 

 have an immaculate white chin. The throat and breast of the 

 Pectoral have a brownish cast, with distinct fine blackish 

 streaking. In the White-rumped these parts are white with 

 less distinct and less extensive gray streaking. In Baird's 

 these parts are buffy with or without indistinct darker 

 streaking. 



Long Island. Rare fall transient, August 14 to October 31; 

 one spring record, May 2, 1878.

 bold T. Lawrence); one seen August 25, 1921 (Bicknell). 



LEAST SANDPIPER (Pisobia minutilla)

 few which occurs occasionally inland. This species and the 

 Tree Swallow are our earliest fall migrants.

 12); (June 22) July 1 to October 18. 



ORIENT. Common transient, occasionally remaining 

 through the summer. April 27, 1912 to June 12, 1908, average 

 May 5 to June 5; June 27, 1910 to September 25, 1913, aver- 

 age July 6 to September 16. 



MASTIC. Common transient, arriving from the north as 

 early as June 22, 1921. 



LONG BEACH. Common transient, April 21, 1921 (Bick- 

 nell) to June 10, 1920 (Bicknell); June 22, 1922, June 27, 1919, 

 and July 1, 1920 (all Bicknell) to September 23, 1917 (Janvrin),
