86 Tar Witson BuULLETIN—No:. 75: 
Island. The species formerly nested in small numbers on Gull 
Island and no doubt on the Charity Islands, and some may be 
seen here at nearly all seasons of the year. 
5. (54) Larus delawarensis. RiNG-BIrLED GuLL—This_ species 
was not noticed about the island, but it no doubt visits them on the 
annual migrations up and down the lake, as numbers were seen 
by the writer at Sand Point in 1908. 
6G. (GO) Larus philadelphia. BoNaApartEe’s GuLut—On August 25, 
five birds of this species were seen fiying near the east beach, and 
on August 27 and 28 nine were seen on the same beach. On Oc 
tober 12, the writer made a trip to Oak Point, where he saw a 
flock of about two hundred feeding along the beach. The fisher- 
men e¢all this species the “little herring gull” and told me that 
they occur in flocks of thousands later in the fall, when the her- 
ring are being taken in the nets. 
7. (70) Sterna hirundo. ComMMon TERN.—This is another spe- 
cies that was seen every day. Two or three hundred made their 
headquarters on Gull Island, and most of these bred there. The 
fishermen said that the island was covered with the nests and eggs 
every spring. Some of the young were still being fed when I ar- 
rived on August 16. On Charity Island, I saw old birds feeding 
young that were able to fiy but not to catch fish for themselves. 
Individuals were often seen to drop into the water and catch and 
eat small fish. On several occasions birds with small fish eross- 
wise in their bills flew across Charity Island on their way to Gull 
Island. At other times dozens were seen dipping down to the 
water of the bay to pick up the flying ants that were strewn over 
the surface. 
Captain McDonald said that in June and July the ants fly all 
over the bay and are sometimes seen in “windrows” on the beach 
like the May flies. The assistant keeper, Mr. Joseph Singleton, 
said that during the summer these ants were found in large num- 
bers on the stakes and the parts of the nets that were out of the 
water, and were a nuisance to the fishermen who had to handle 
the nets. Tle said that these were large black ants, mostly with, 
but some without, wings. These no doubt form a large proportion 
of the tern’s food at this time of year, for as late as August I saw 
them continually dipping down to the surface, and the stomachs 
of several taken on September 15 were packed with ants. One 
Was opened and was found to contain 144 ants. This same spe- 
cies of ant was found under stones at the water’s edge on Charity 
Island. 
8. (120) Phalacrocorar auritus auritus. DousnLte CRESTED CoR- 
MORANT.—The only bird of this species seen was flying across
