semigeek:mattwnz: I have never seen a cat attack a big bird like a tui or wood pigeon, and they also tend to stay in the trees. It is mainly sparrows they they seem to get, which are essentially rats with wings.
Our cat over the course of a year has caught 3 seagulls, and they are pretty quick birds.
Although seagulls do spend a lot for their time on the ground as they are rats with wings, so doesn't surprise me. I don't live near seagulls myself. But I am sure that a seagull could give many cats a good peck to get them off.
