RSPCA blokey turned up (very handsome aussie surfer type!) and it's wing was indeed broken. He advised that he'd take it to the vet, but it would be put down, because it's just too expensive to keep all the gull chicks they get in. He did say if it had been older and just sprained it's wing they would have kept it until it healed, but broken wings are just too complicated. It was very cute and fluffy up close!
We get hummingbirds in our garden. We have a feeder hanging off the deck, and these bizarre little birdies buzz up to it, flapping their wings like crazy, and suck all the lovely sugar water up. They just don't look real - they're the closest thing to a CGI bird that I can imagine, because they move so suddenly that they seem to travel from place to place by teleportation. And they make this ultrasonic chirping noise.
Weird things.
Apart from that, the only wildlife I usually see close up is dead squirrels on the road. Very colourful, especially if freshly flattened, but hardly pleasant to run past.
