For yet another spring, a red-winged blackbird has been divebombing people as they walk by its nest on Parliament Hill.

Male red-winged blackbirds screech at other males to protect their territory, and sometimes they'll attack people who come close to their nests. (AP Photo) The fun speculations abound.

Maybe it's mad it wasn't chosen as the unofficial bird of Ottawa, or perhaps this is the bird's way of pushing for Senate reform?

Maybe the Parliament Hill bird is hoping for this kind of CBC TV coverage.

More likely, it's simply protecting its family.

But it didn't take long for a Twitter account to materialize, of course.

.<a href="https://twitter.com/ThomasMulcair">@ThomasMulcair</a> I am completely in favour of Senate abolition. That is 105 less people threatening my nest by the Senate entrance. <a href="https://twitter.com/hashtag/cdnpoli?src=hash">#cdnpoli</a> —@ParlBird Its yoga on the Hill today. Excellent. —@ParlBird I was just attacked by a bird in front of an elementary school class and a group of Parliament staff, how's your morning going? —@daniellediscala She's baa-aack. <a href="https://twitter.com/cmaconthehill">@cmaconthehill</a>: I just got attacked by the infamous Parliament Hill bird. I didn't know the attack season had begun. —@kady After that bloody bird in front of Parliament nailed me three times in a row on the head, I'm a little paranoid. —@KimberleeTaylor
