Lake Hamilton in tlie Yellow Creek Valley was filled in 

 1905 with an area of about 100 acres. This larger reservoir 

 greatly increased the numbers of water birds that stopped 

 over in this locality, and some years there have been thou- 

 sands of ducks on this body of water for one or two days at 

 a time. My first and only record for the Black-crowned 

 Night Heron was along the shore of this lake April 21st, 1911. 



In 1910, Pine Lake, with an area of 400 acres, near the 

 head waters of Yellow Creek and about 12 miles south of 

 Youngstown, began to fill with water, and during the spring 

 migration of 1911 great numbers of water birds stopped over 

 for days and weeks at a time. This was probably on account 

 of the decaying vegetation in the water, which furnished 

 unusual feeding conditions. Since this larger reservoir was 

 filled the water birds have not been as abundant at the other 

 reservoirs or visited them as frequently. I am satisfied that 

 during the year 1913 I observed more water birds and shore 

 birds about Pine Lake as to numbers than during all other 

 years of observation in the Youngstown district put together. 

 My first record for the Canvas-back, April 9th, 1913, and a 

 few later dates, was on this lake. On April 15th, 1913, more 

 than 100 Horned Grebes were on the lake at one time. Octo- 

 ber 3]st, 1913, while standing on the east shore of Pine Lake 

 with i\Ir. John P. Young, about 200 Canada Geese and a 

 flock of 13 Blue Geese circled over the lake for a time, and 

 then continued their southward journey. This is my first 

 and only record for the Blue Goose. Previous to 1913 I had 

 not recorded the Wood Duck, except April 2ud, 1911, when 

 a male visited IMill Creek Park. However, during the fall 

 of 1913 I listed three Wood Ducks — September 12th, and 

 about 30 September 14th at Pine Lake. Some of these, or 

 others, remained at this lake until September 28th. During 

 the season of 1913 I added to my list quite a number of species 

 of shore birds for this locality around the shores of Pine 

 Lake: Golden Plover, October 23rd; Semi-palmated Plover, 

 May 9th ; Baird Sandpiper, May 10th ; Red-backed Sandpiper, 

 October 23rd ; Semi-palmated Sandpiper, May 10th ; Sander- 

 ling, September 14th. While these were my first records for
