Tringoides macularius: Spotted Sandpiper 



Abingdon and Albemarle islands. 



A male (No. 1990 C. A. S.) shot at Villamil, Albemarle 

 island, on May 2, 1906, was in fairly high plumage. A sec- 

 ond individual was seen on the south shore of Abingdon Island 

 on September 22, 1906. 



In 1905, two females, Nos. 1991 and 1992, were taken on 

 Cocos Island, Costa Rica, on September 4 and 7 respectively. 

 Several examples were observed daily on September 4, 5, 6, 

 7, 8, and 11, at both Chatham and Wafer Bays. 



On September 13 a female Semipalmated Sandpiper 

 (Ereunetes pusillus), No. 1993 C. A. S., was taken on the 

 beach at Wafer Bay. 



Calidris arenaria: Sanderling 



Abingdon, Albemarle, Bindloe, Charles, Chatham, Hood, 

 James, Jervis, and Seymour islands. 



The Sanderling was seen only two or three times in the 

 saline coastal lagoons, but was fairly common on certain occa- 

 sions on the ocean beaches. It was observed in July, August, 

 October, November, February, and March. Like the Black- 

 bellied Plover, it was very shy and difficult of approach. 



Limonites minutilla : Least Sandpiper 



Abingdon, Albemarle, Barrington, Charles, Indefatigable, 

 and James islands. 



The Least Sandpiper was not infrequent, being noted on 

 all of the above-mentioned islands during the months of July, 

 August, September, October, November, and February. On 

 July 28 several were observed in a large lagoon on northeast- 

 ern James ; with them were a number of Hudsonian Curlews, 

 Black-bellied Plovers, and Semipalmated Plovers. They 

 haunted the ocean beaches as well as the lagoons. 



A few were seen at Wafer Bay, Cocos Island, Costa Rica, 

 on September 4 and 11, 1905, specimens being secured.
