SOME NOTES ON CONNECTICUT BIRDS. 
BY IRA N. GABRIELSON. 
Durine 1916, while in Connecticut engaged in work for the 
Biological Survey, the writer made a number of notes on the birds 
of the State. These notes have been compared with the data found 
in the state list! and such as seem to be of interest are presented 
here. 
The notes presented are either records of species which are 
uncommon in the state or unusual dates for common birds. All 
specimens mentioned are now in the collection of the Biological 
Survey, unless otherwise specified. 
I am indebted to many friends for courtesies received during 
the season and particularly to those mentioned in the following 
notes as companions in the field. I wish especially to express my 
appreciation of the kindness shown to me by Dr. Louis B. Bishop. 
1. Colymbus holbelli. Hois@ii’s Grese.— Wilbur F. Smith and 
I saw Holbeell’s Grebe on April 15 at Norwalk. This bird was feeding a 
short distance off shore and the markings were plainly visible through the 
glasses. Mr. Smith informed me that a live bird of this species was cap- 
tured and brought to him on April 20 just after I had left Norwalk. 
2. Gavia immer. Loon.— One observed at Norwalk on October 27 
by A. A. Saunders and myself. This seems to be an early date. 
3. Larus argentatus. Herring Guitu.— No summer records are 
given in the ‘ Birds of Connecticut.’ Several ornithologists informed me 
that Herring Gulls were becoming more common and occasionally remained 
during the summer. I have the following dates for the summer months: 
Norwalk, May 31, a number over the harbor; Old Lyme, June 12, a flock 
of considerable size about the mouth of the Connecticut River; Norwalk, 
July 10, a single bird over the harbor. I left the shore on July 14 and did 
not return again until after the Gulls became common in fall and conse- 
quently cannot say whether any were about during late July or early August. 
4. Larus delawarensis. Rinc-BILLED GuLtL—On April 11 at 
Greenwich, Wilbur F. Smith and I saw a number of Gulls in immature 
plumage which I am positive were Ring-billed Gulls. We watched them 
at close range for a long time. They were distinctly smaller than the 
Herring Gulls associated with them and the subterminal black band on
