Musings on Site Fidelity

Buckle up, this post may be what my stats professor at Indiana would call “chewy.”

The wildlife surveys are still going strong—pronghorn fawns started showing up about a month ago, and I’ve collected quite a few data points on nesting and chick-rearing for some of the BLM and Wyoming Game and Fish’s birds of concern.

American avocet (Recurvirostra americana), trying to distract us from its chick farther down the road.

Although I haven’t actually run any numbers yet, the distribution patterns I’m noticing make me much more confident about the conservation prospects of some species than I am about others. Part of that seems to depend on basic habitat requirements—I am increasingly suspecting, for example, that the sage thrashers I mentioned a couple of months ago are more adaptable to habitat variations than has previously been recognized—but how different animal species respond to habitat changes in one location can also be very important.
