Gavia immer. Loon.— Observed as late in the spring as June 1 (1907, 
Mt. Sinai) and we presume in fall migration July 9 (1911, Mastic). Mr. 
W. T. Helmuth reports this species from Easthampton July 6 to 7 (1915). 
Perhaps these early July birds should be considered as summering or even 
as stragglers from the spring migration. One, in immature plumage, was 
seen off the Mastic beach on June 24, 1916. Migrating Loons fly with the 
bill open. Doubtless so heavy and short-winged a bird requires a great 
deal of oxygen for protracted flight. The migration of the Loon is a very 
interesting and irregular one. The species arrives from the north early 
in August, so far as we know young birds as well as adults, and is frequently 
met with through the month. A lull then ensues, and during September 
and October the Loon is usually decidedly uncommon. There is frequently 
a flight early in November. After another lull the main flight of the fall 
takes place the latter part of December, and usually by the first of January 
the wintering individuals are left behind. Their numbers vary greatly in 
different parts of the island from year to year. The spring migration starts 
with the first mild weather in March, increasing steadily until the last 
week of the month and the first week in April, when the species is abundant, 
traces of the summer plumage being evident. From this time till the 20th 
of May, very few Loons are seen, at least at the western end of Long Island. 
Those seen are usually still in the winter plumage even in the middle of May. 
From May 20 to June 1, there is another big migration of Loons mostly 
in fullsummer plumage. They are most abundant from May 24 to May 
28, and a few days later only stragglers remain. 
Gavia stellata. Rep-rHroaTeD Loon.— Six white-throated birds 
observed off Herod’s Point, on the Sound, on August 24, 1905. They were 
observed from a blind on the beach, and came within thirty feet of the 
observer. (R. C. M.) 
Alle alle. Dovexre.— Specimens have recently been sent from Mon- 
tauk Point to the Brooklyn Museum, as follows: 1 on February 25, 1916; 
1, a female, on April 3, 1916; 1, a female, on May 29, 1916. The last bird 
was perfectly fresh when picked up dead on the beach. Mr. A. H. Helme 
tells us of Dovekies shot off the south shore of Long Island in June. Mr. 
W. 8. Dana, of Mastic, has a mounted specimen which he collected in 
Forge River, Moriches Bay, in August, 1918. December 11, 1909 (10 
miles off Shinnecock) two hundred seen, apparently the largest number 
seen in Long Island waters. 
Rissa tridactyla tridactyla. Kirriwakn.— October 13 and 27, 1912 
(Long Beach) are the earliest fall dates. The fall of 1912 was characterized 
by the early arrival of an unusual number of northern species. 
Larus hyperboreus. GLaucous Guiu.— Recent records for western 
Long Island are as follows: January 8, 1912 (Manhattan Beach) W. H. 
Wiegmann; February 12, 1912, March 3, 1912, (Long Beach). 
Larus marinus. Great BLACK-BACKED GuULL.— May 13, 1910 (Long 
Beach) and April 8, 1912 (Gardiner’s Island) latest spring dates. 
Larus philadelphia. Bonapartn’s Guiu.— May 19, 1912 (Long 
Beach) latest spring record.
