Larus delawarensis. Lake Umbagog. 1883, October 26. After breakfast I discovered a flock of strange Gulls on the river beyond the first pond. I took them to be Ring-bills. They alighted in a thick cluster, sometimes on a mudbank, some- times on the dead stubs. One was dark, the rest snow white. We afterwards tried to shoot one but found them just a little too shy. I got within good range of one behind the river bank, but hearing a Duck quack, did not fire and finally the Gull saw me and flew. 71
