I hadn't considered pigeons, however, the owner of a local Chinese restaurant in Buffalo was arrested for clubbing mallards along the bank of a stream that runs through a park.
Speaking of pigeons, there is a large population of them in and around the plant I work at in Niagara Falls. A few years ago, a Red-Tailed Hawk came swooping down out of nowhere and nailed a pigeon in the girders on the side of the building. After a few minutes it carried the pigeon to a pipe bridge, just below the roof of another building. A robin perched itself on the edge of the roof, just above the hawk. Then two swallows started circling above the hawk and dive bombing its head, while it was trying to eat. Whenever it got distracted enough by the swallows, the robin would jump down from the roof to the pipe bridge and steal a piece of the pigeon. This went on for about a half hour, until the hawk took it's prey and flew away. There was such a crowd gathered watching all this, that we almost had to shut the plant down.
