u flock of yellowieys wlien found. Tliis is the writer's only 

 reconl for the county. 



■40. GaUiniKjt) delicata. AVilson's Snipe. The AVilson Snipe 

 or "Jack Snii)e" was tolerably common in spring from April 

 15 to May 4 and a much more common migrant in fall from 

 Septendjer 26 to November 18. A single bird remained about 

 the sewer outlet at .Marshalltown until November 18, 1913. One 

 taken November 7, 1913, is in the collection. 



41. Macrorhaynphus griseus griseus. Dowitcher. A rare 

 spring and fall migrant. One was secured from among a flock 

 of sandpipers on August 10, 1914, and two others were seen on 

 May 22, 1915. On both occasions the birds were found in a small 

 swampy spot near the Goose ponds. 



42. Pisohia macuhita. Pectoral Sandpiper. This was the 

 most common sandpiper of the region in both spring and f;dl 

 migrations though far more abundant during the latter seasoji. 

 The spring migration extended from April 4 to May 22, and the 

 fall from July 8 to November 18. The waters in the Goose ponds 

 became low during July and August and great flocks of sand- 

 pipers fed over the mud flats thus exposed during the latter 

 month. Though the fall migration was extended over a long- 

 period by straggling individuals or small flocks the sandpipers 

 were most abundant from about August 10 to September 7. 

 Some notes on this and succeeding species wQve published in 

 the "Wilson Bulletin, Vol. XXVI, p. 45. 



43. Pisohia juscivoUis. White-rumped Sandpiper. Only two 

 records are at hand for this species in spring; namely, ^lay 4 

 and 8, 1914. Two birds were seen on each occasion. In the fall 

 it was noted regularh' from August 19 to 27, biit between those 

 dates was ver\^ common. One taken on August 19, 1914, was 

 too badly shot to make a skin. A single straggler was collected 

 November 7, 1913, at the Goose ponds. It Avas so fat that the 

 skin broke open on the breast when it fell. This bird was re- 

 coT'dod in the "Wilson Bulletin, Vol. XXVI, p. 45. 



44. Pisohia hairdi. Baird's Sandpiper. Noted as a spring 

 migrant only in 1914 wlien a few were seen on several dates from 

 April 25 to May 11. In the fall tliey were a tolerably common 

 migrant from August 15 to September 7. They could readily be 

 picked out in the great mixed flocks of sandpipers that fre-
