Amy Hooper over at WildBird on the Fly recently blogged on what a border fence could mean for the birds and birders visiting south Texas. Read her entire post here.
I think the idea of a big fence stretching hundreds or thousands of miles is a silly proposal, more like what kids playing in a sandbox would suggest. The people crossing our border are already making it through many difficult obstacles and I find it hard to believe that one more obstacle is going to make a difference.
