Two Gulls at Fort Erie

I grew up with the Herring Gull in Lake Erie and the Niagara River. It is the common “Sea gull” inland and along the Atlantic coast. Look below. Some time I am not sure when the smaller Ring-billed gull took over. In 2008 in the Fort Erie area the Ring-bills reign. Its voice is a loud, raucous mewing cry like that of its larger brother the Herring. Experts tell us that Ring-bill has a higher pitched call. I associate the Herring with our garbage dumps. Am I right? Near the OLD Fort Erie you see large colonies of Ring-bills literally hundreds. I don‘t remember large colonies of Herring gulls. Both are marvellous fliers, eh..
