What visitors say
In other parts of the park, we heard northern cardinals, pyrrhuloxia, and cactus wrens calling endlessly.
The next morning while we sat outside our cabin, enjoying the cooler morning temperatures and drinking coffee, we observed a Lark Bunting foraging nearby.
While on our way to the park, we saw a gray fox run across the road.
In Big Bend National Park, we camped at Rio Grande Village Campground, where burros and horses from the Mexican side of the river graze freely throughout the campground on grass so short it is hard to believe this activity is worth the energy required.
