The other day I saw two gulls chasing each other as they flew, and one suddenly "attached" itself to the other, as though to mate. They continued flying in this way for several seconds. It is March and still cold and snowy here in Quebec. What behaviour was I witnessing? Do birds mate in flight?

Many bird species do mate in flight. Some hawks, swifts and others do. I'm not certain of gulls, but i believe they may.
