540 AXNALS OF THE CaRNEGIE MuSEUM. 



65. Actodromas fuscicollis. White-rumped Sandpiper. 



One of the rarer transients among the shore-birds. The following 

 specimens are in Mr. Sennett's series: one, October 23, 1874, "head 

 of bay " ; two, June 4, 1875, "on the Peninsula " — the only spring 

 record, and a very late date — and one October 29, 1889. The spe- 

 cies was noted by the writer as quite common on the occasion of the 

 great storm of August 29, 1893, when it was found in small flocks at 

 the mouth of Mill Creek, feeding in the muddy slime, and very tame 

 and unsuspicious. Since then Mr. Bacon has met with it a few times 

 at the same place. October 11, 1894, he shot a single specimen, 

 also again on September 28, 1895. On October 9 and 10, 1895, he 

 secured two birds each. In the fall of 1900 a single specimen was 

 secured (on the outside beach) by Mr. Worthington on October 15. 



66. Actodromas bairdii. Baird's Sandpiper. 



Baird's Sandpiper, essentially a bird of the interior, and recorded 

 but once from Pennsylvania previously (Todd, Auk, VIII, 1891, 

 240), proves to be a species of moderately common and presumably 

 regular occurrence as a fall migrant at this locality. It is found singly 

 or in pairs, always on the outside beach, and occasionally in the com- 

 pany of other shore-birds. September seems to be the month when 

 its migration is mainly performed, the earliest birds having been noted 

 in 1900 on September 5, and the last September 29. In addition a 

 single specimen was secured as late as November 2, but its condition 

 indicated that it had been wounded and thus unduly delayed. Mr. 

 Bacon has observed the species on the following dates : August 24, 

 1892; September 16, 1893; September i and 7, October 5, 1894; 

 October 3, 1895; September 11, 1897; August 22 (the earliest 

 record), September i and 5, 1902. He does not recall having seen 

 more than a pair together. 



67. Actodromas minutilla. Least Sandpiper. 



This diminutive shore-bird has been observed as a transient visitant, 

 quite common in both spring and fall. It may be looked for almost 

 anywhere about the bay where there is a mud-flat, or where the 

 aquatic weeds cast up by the waves thickly strew the outside shore, and 

 it is occasionally found in flooded fields also. On its way northward 

 it passes through in May, the earliest arrivals in 1900 having been 

 observed May 8, while from Mr. Bacon's notes we learn that May 24 

 (1893) is the latest date at this season. It returns in August, the
