The following list of birds I observed on Cedar Point within two miles of its extremity, from July 30th to August 20th, 1901, while a student at the O. S. U. Lake Laboratory. The list is not so complete as it might be. I found the birds I did for the most part in short daily visits of about an hour each, generally in the afternoon. One whole day I spent on the Point and two half days. With one exception, that of the American Herring Gull, I think all the species named nest in the neighborhood of Cedar Point. The list ought to be much extended by going over the part nearer the mainland. I think at least fifteen or twenty more species ought to be found there as summer residents. I rode from Oberlin to Sandusky several times and the additional species I saw in Erie county I shall add in a list by themselves. The most noticeable of these were the Bank Swallows. They were in immense flocks along the road from Sandusky to Huron. Sometimes as many as five hundred would alight on two lengths of telephone wire.
