Good god they are everywhere! Here we visit a seagull festival in Japan. Watch the mating carnage - including one bloke that was rudely interrupted. Who does that man? Come on...
Wow...make sure you watch the video toward the end. Some dude gull and chick gull are going at it, with other gulls like 2 or 3 ft away the whole time. Like, it's not awkward at all. Anyway, this couple finally gets over the clumsiness factor. You know, the part where when birds do it, the male basically steps on the back of the female, and then proceeds to stand on her back the whole time. It's all very classy and elegant. Anyway, they finally get their rhythm going, and this voyeur gull dude next to them finally flips his lid, and then proceeds to bite down on the wing of the dude as he's getting close to finishing up. Wow, that dude is not only NOT a wingman (oh, man, "wingman." I wasn't even going for the avian-style joke there), but just about the biggest cockblocker on that island of about a kajillion gulls.
I think he did it because gulls section off tiny bits of "property" (notice how they don't walk around) and the aggressor gull felt that the male who was mating was spreading his wings into its own property. Generally trespassing is met with retaliation
Alaska Department of Fish and Game . As many as 20,000 seabirds build nests in the craggy rock faces and cliffs of Gull Island, on the south side of Kachemak Bay-Its impossible to map actual number of mating each year, because of travel and migratin numbers depending also on Yamalo Nenets peninsula.
