The Rio Grande Valley in Texas really is a birding paradise. Think of this: an area around 140 x 40 miles that has recorded over 500 species of bird. It is singularly one of the best areas to go birding in the whole of US - which is a mighty big place as you all well know!
Add to that over 300 butterfly species and we're talking proper bonanza!
