So apparently hummingbirds are very territorial. Our balcony is now the scene of a thumb-size territorial dispute, complete with miniature mid-air dog fights. It's like Snoopy and the Red Barron out there.
It's really interesting to watch them, and work out their techniques and strategies. Mainly it involves flying very fast at the other bird, with maybe some high-pitched squeaking, but they don't appear to physically fight one another, thank goodness. If that happened we would take down the feeder immediately.
Of course now we're starting to recognise some of the different birds, so I'm sure we'll start to take sides soon. And actually wouldn't the Fighting Hummingbirds make a great team name? For a netball team maybe? Very girly, but it has a ring to it I think.
