It's the fall here in Seattle. Many big spiders are building webs close to warm buildings, trying to eat as much as they can before they lay there eggs and die.

In the back yard two squirrels are building a nest together. I didn't realize that squirrels could be social; in the summer they only fight. But there they were, both pulling leaves and twigs off an alder, and carrying it back to the nest.

One squirrel was very efficient, making a large leap from the nest to the alder, ripping off a large twig of leaves, and then leaping back to the nest. The other squirrel took a longer, more circuitous route to the alder, and brought back fewer leaves.
