As I mentioned in the OP, they’d congregate in the palm trees and power lines right outside my home and squawk up a storm at sunrise and sunset. Much like the roar of jet planes flying right overhead at low altitude on their way to/from Lindbergh Field, it’s just part of the background noise of life in OB. You don’t really think about it, but when you end up living somewhere else, its absence is noticeable.
The last ones likely succumbed to disease, and also they may have been one of those species that simply will not breed unless there are thousands around. The Passenger Pigeon was one of them.
I KNOW they conspire to land in my yard at the ass crack of dawn when I am most hung over. There is no way they aren’t doing it on purpose each and every time. Fuckers.! My wife is a hardcore 4th generation birder and even SHE hates the fuckers. So damn loud, so damn early.
Well I work 2nd shift (2pm-10pm), so I can’t start drinkin until 9ish pm. And I’m always up until like 4am anyway. On my day’s off, I’ll sometimes be going to bed just as they start their hideous squawking. Hideous hideous squawking. It’s not like its just a loud sing songy bird by any means. Tho that is also annoying, it isn’t as deathwishy.
No, my only choice is to take over the Evil Geniuses For A Better Tomorrow and use their Orbital Mind Control Lasers to fry their little birdy brainies.
It seems odd to me that so many species of parrots can live and breed in California, yet there there no native species of parrot, despite populations just a little bit south in Mexico.
I’m wondering if the parrots are relying on water from humans, or some other human change to the environment, and back 200 years ago they wouldn’t have been able to survive.
Or maybe it’s one of those things where rare 50 or 100 year weather events will wipe out the species. Lots of non-native trees thrive in Florida, then along comes a big hurricane and the trees get flattened.
All parrots with the exception of Monk Parakeets nest in cavities, either tree holes or sometimes ones in rock or soil. I would expect that a stronger limiting factor in southern California may have been the lack of enough large trees with holes big enough for nesting. Humans probably provided many more potential nesting sites by planting trees, and in crevices in buildings and other structures.
Part of the Monk Parakeet’s success is due to the fact that it builds its nest out of sticks, and isn’t reliant on cavities.
