and a broocl of seven at Snake Point (Fig. 13). No nests were found by 
the writer, but a great number of suitable cavities were seen in the old 
oak trees. Mr. Singleton has found nests of this species on the ground 
among the rocks on North and Stony Islands. 
4. Anas rubripes. Black Duck. — The black duck was not seen in 1911, 
but a flock of nine was seen several times about Gull Rock in 1910. These 
were probably bred on one of the islands, as they were too young to fly 
when first seen. 
5. Dafila acuta. Pintail.— This species was reported by the keepers 
as not uncommon about Charity Island in spring and fall, and during the 
spring of 1911 one was thought to have nested on Snake Point. Mr. 
Singleton looked in vain for the nest, but later some young ducks appeared 
about the island and were seen by the writer, on July 6, in the pond. This 
brood was seen about the beaches and when approached always swam off 
into the Bay. On July 29 two of these young birds (a male and female) 
were seen, and they could barely fly. The writer has been unable to find 
any breeding record for the state, but the A. O. U. Check-List records it 
as breeding as far south and east as northern Illinois. 
6. Oidemia deglandi. White-winged Scoter. — On July 7, the writer 
found the dried remains of four scoters on the beaches (Fig. 6-7) of 
Charity Island. Captain McDonald stated that they are rather common 
on Saginaw Bay in the late fall, and on Nov. 11 an adult male collected 
by Mr. Singleton on Charity Island was received at the Museum. The 
fishermen call this the “big black duck” to distinguish it from the common 
black duck. 
7. Olor columbianus. Whistling Swan.- — On April 15 the keepers saw 
nine swans near East Point, where they fed and rested on the water all that 
day. They were the first ones ever noticed near the islands by the keepers. 
8. Botaurus lentiginosus. Bittern. — Only one bittern was seen, a bird 
that flew over the Charity Island clearing on the morning of July 27. 
Later in the day it came again to the clearing and flew about overhead. 
The species probably did not breed on the islands either in 1910 or 1911. 
9. Ardea herodias herodias. Great Blue Heron. — A large nest of this 
heron was found in an old Norway pine near the eastern border of the 
pond (Fig. 10), Charity Island, on July 7. An adult heron was 
flying about overhead, and while no young could be seen in the nest, the 
writer was inclined to believe that there were some in the vicinity. On 
July 20 four young birds were seen and afterward nearly every day during 
our stay were observed along the beaches. (Figs. 6 and 12). The adult 
birds made daily excursions to the lines of fish nets until the latter were 
taken out, about July 15. One was seen on Little Charity Island on July 
28. 
10. Butorides virescens virescens. Green Heron.— This species was not 
seen in 1910 and only once in 1911. A specimen was found at the edge of 
the pond on Charity Island on July 8. It probably did not breed as none 
were observed after that date. 
11. Philohela minor. Woodcock. — The woodcock was not a common 
breeder on Charity Island, but at least one pair was observed in May by 
the assistant keeper, Mr. Singleton. This was near an old garden which 
is now grown up to willow and alder bushes. In the same place, on July 
8, we found the borings, and on June 17 flushed a large adult and an imma- 
ture bird about half-grown. An adult was also flushed by the writer on 
July 12.
