ing the July and early August studies, with scattering young 

 plumaged birds, the most of which were still being fed. As the 

 weeks passed the mottled birds increased in numbers until there 

 were almost none in the full summer dress. It was clear that 

 there was no breeding colony on Pelee Island during the summer 

 of 1910, whatever may have been true at any other time.. Com- 

 pared with the preceding species, the numbers were small at the 

 time of the beginning of the 1910 studies, July 16, but by the first 

 of September the two species were about equal in numbers. The 

 birds of this species were somewhat less wary than of the Com- 

 mon, so that the succession of perching birds on the sand spit was 

 Herring Gulls on the extreme point of the spit, then the hosts of 

 Common Terns, and finally, ranging well toward the first vege- 

 tation on the broader base of the spit, the particolored Black Terns. 

 Photographs of the birds as they were leaving the spit, taken 

 from the spit itself, show practically no birds but the Black Terns, 

 because they were always in the foreground. 

 Anas jHatyrhynchos. — Mallard. 



Three were found in the small swamp at the base of Fishing 

 Point on August 6, 1910. Of course there must be great numbers 

 during the migrations. 

 Anas ruhripes. — Black Duck. 



Seen only during the 1910 studies. There were four in the 

 Fishing Point swamp on August 5, and two on each of the three 

 succeeding days. The other records are August 17, one ; 24 and 

 25. two ; 28, four ; September 3, one ; and 6. four. As noted else- 

 where, a few individuals of this species were usually found in the 

 vicinity of the Chicken islands. These individuals may have wan- 

 dered over to Pelee. When they were startled they invariably 

 flew toward the Chicken islands. 

 Mareca americana. — Baldpate. 



A small flock was noted flying westward across the point on 

 August 5, 1910, none others noted at any time. 

 Querquedula discors. — Blue-winged Teal. 



A pair with young was noted in the swamp of Fishing Point 

 for a few days early in August, 1910. The nesting must have 

 been at this swamp. 

 Aix sponsa. — Wood Duck. 



There were three individuals in the swamp during the first week 

 in August, 1910. Whether they had nested there could not be de- 

 termined. 

 Botaiirus lentif/inosus. — Bittern. 



Beginning on August 5. 1910. when a tliorough study of the 

 Fishing Point >wanip was made, one or two of these birds were
