RING-BILLED GULLS ( Larus delawarensis ) ON LAKE ONTARIO.— 
For some years past I have been interested in the gulls of 
Ontario, and, while I have found the Herring Gull breeding in 
several of the little lakes north of Kingston, there has always 
remained unsolved the problem of the gulls to be found on lake 
Ontario during the breeding season. I always supposed that 
these were Herring Gulls, probably immature or barren birds, and 
possibly a few birds which flew here from the inland lakes to feed. 
This was because in the early morning many gulls could be seen 
going north, and there was reason to believe that some birds 
returned in the evening. This year I have been watching the 
gulls on Snake and Salmon Islands very closely, and have ascer- 
tained positively that the flock, numbering between three and four 
hundred, is made up almost entirely of Ring-billed Gulls, There 
may be half a dozen Herring Gulls among the number, but cer- 
tainly not more. Nearly all are in immature plumage and are, in 
probability, merely here during a developmental period. It wily 
be interesting to note whether the gulls we see on these islands 
piss: SEs 53. 
every summer, are of the Ring-billed variety, and more interesting . 
still to learn if any the Ring-billed Gulls, breed in the lakes of 
Frontenac and Addington. Of course, as is well known, it is 
many years since gulls bred on any of the islands in Lake Ontario, 
even the Common Terns are disappearing.
