at last

The moment I’ve been waiting for. Observing ravens from 3rd floor of new campus library (Del Reyvens presumably). They soarcled up on therms from Playa Vista and then glided down towards Lincoln Ave and the west end of campus.

Clever tracking trick

Wright and

co-workers studied cooperative foraging strategies using sheep

carcasses placed at varying distances from the roost that were

baited with color-coded plastic beads. These beads were ingested

at the carcass and regurgitated in aggregations of pellets back in

the roost, the spatial distribution of which consistently reflected the

geographical location of bait sites.

…and way easier than strapping radios to ravens. This could be an effective method in LA. We obviously have mobile juvenile gangs here, but their easy access to landfills makes any questions about their foraging less interesting. The interesting questions come up in the area of pairs and their territories. Most of the ravens I observe in Hollywood are pairs, whether or not they own their own territories. In the Santa Monicas – Griffith Park, Elysian Park, and Verdugo – is where the juvenile gangs roost and rendezvous. ┬áBy contrast, the population in the San Gabriel and San Bernardino mountains is very sparse.

Shark shmark

Shark Week on Discover channel. Let’s see… giant fish pigging out on tuna. Giant fish pigging out on easy to catch seals. Giant fish pigging out on floating carcasses. Giant fish mistaking zodiacs for floating carcasses. Giant fish being tricked into attacking seal-shaped pieces of carpet…

Wake us when it’s over. Oh, and can giant fish stop eating long enough to make tools and solve problems?
