Gillian rides in the backpack (good workout for Mom!) and Sine is on a leash till we get through the gate into the park. Lately, it's been quite cool, so Gillian's bundled up a bit. I get warm very quickly, hiking up and down
In recent weeks, we've been feasting our senses on Nature's annual display of color. In our part of the world, autumn is primarily a golden event. Having grown up in the
Midwest, I used to miss the oranges and reds of oak and maple trees, but I've become quite fond of the golden flowers, shrubs, and trees, particularly with Colorado's brilliant blue sky as a backdrop. The vibrant pinkish purple trumpets of the four o'clocks and the star-like purple and white asters provide small dots of additional color to the otherwise green and gold landscape. We also enjoy watching the birds--mostly house finches and pine siskins--prying seeds from the native sunflowers and mullein, the last hummingbirds zooming in and out of the Russian olives before heading south for the
winter, and the grasshoppers and small butterflies that spring and flutter from the grasses and bushes along the paths. I've seen deer tracks in
several places, but no deer. From occasional scat, I know that foxes are about.
The other morning we saw a small group of 5 or 6 turkey vultures sunning themselves on the limbs of a dead tree and on the tops of nearby boulders. They, too, are heading south for the winter.

On the concrete path, we came across the remains of another autumn migrant: a Desert Tarantula (Aphonopelma chalcodes). This particular one was rather squished and had been torn apart. Every fall, the males of this species head out to find and mate with females, who are waiting in burrows in the ground. The males typically live only about 3 years and are sometimes eaten by the females. The females have a lifespan of up to 20 years! Check out these links to see what they look like:

The tarantulas, about 10 cm in diameter, are known to be aggressive only when severely provoked (I know of guys who have teased a spider with a stick or pin flag only to have it jump onto their pants leg!), but typically are so single-minded in their quest that they are practically oblivious to obstacles. They walk in nearly a straight line, climbing up and over anything in their path. They are very common in rocky wooded areas in the Southwest during the months of September and October. Several years ago, while working on an archaeological survey for a gas pipeline, a co-worker and I had a running competition to spot the most tarantulas. At the end of the week, we each had scored 30-plus! I've gotten quite good over the years at spotting them, even from a moving vehicle, but I have yet to see a live one in this park.
Here's a little movie of a tarantula that I made a couple years back....
