Re: Where have the ------ gone? (Pika, Lakes, Eagles...)

Hi Mark,
Yep, I agree with you that the abundant water this year may have been good for a lot of critters, as I do recall seeing more ground squirrels than over the preceding couple years. And, this may also account for the apparent profusion of Piute pass pika. But, I'm still a bit sanguine about the crow/raven issue. I'm not doubting the observations of the Yosemite ranger, but what I've found to be remarkable is that I've run into crows/ravens in places I consider to be pretty remote wilderness. This includes Kaweah Basin (in June, 2009!!!), the upper reaches of the Kern (where, about a decade ago I'd seen the largest golden eagle I'd ever encountered anywhere) and upper Second Recess (August, this year). Anyway, I've seen no eagles in places where the corvids have been and this implies either that the eagles have been laying low, or they headed elsewhere. I did hear an independent theory that the golden eagle population tracks the bunny population (which, apparently, has been in a downward trend), so maybe when bunnies come back, so will eagles. I hope so!
