Most lizard family (esp. earless types) females in these parts get orangey when preggers. Not too many other types display that marking. I think newly hatched babies look similar to gravid females.

The other likely prospects for lizards in this part of the woods -- geckos (too banded, reticulated or blah to be confused here), the absence of other spines or horns and not "snakey" or long stripes along the back (skinks, racerunners etc) fairly narrows the list.
