John O. and I birded Hahamongna, which was SO depressing! They've DESTROYED it! Then we tried (futilly) for the Zone-tail. They were HUNDREDS of Painted Ladies at both places.

1. I have seen Black Phoebes catching and eating them.
2. KPCC had a short report (I can't remember if it was only a local report or on the national NPR broadcast, but they said that the Painted Ladies are flying up from Mexico because there are too many of them for the local plant life to support (I was driving and only half paying attention). Regardless, this large movement/migration appears to be cyclical, but not annual. Maybe based on prime numbers, like cicada populations (because they only become visible--therefore edible every few years, no predators can base their diet or life cycle on cicadas)...
