How will border fence affect Texas birding?

Last year, Congress approved a 700-mile fence along the border between the United States and Mexico. Folks in Texas are concerned about its implementation.

Birders and naturalists are concerned about the effects on birds and other wildlife, and I share that concern -- not just for the animals but for the economies of the south Texas towns and cities that benefit from ecotourism.

I don't know, though, how to balance the need to protect wildlife habitat with the need to enforce the border/stop illegal activity along it. How do we reconcile very different yet equally valid priorities? Share your ideas with your representatives in the House and the Senate.
