MOSS BLUFF, La. (AP) — Fifth-grader A.J. Williams of Moss Bluff already has a scientific publication. The 126-word-long note in "Herpetology Review" reports that the Rio Grande chirping frog — native to Mexico and far south Texas — is living in Moss Bluff.

A.J. helped his father — LSU-Eunice biology professor Avery Williams — hunt through woods for the half-inch-long frog.

Moss Bluff is far from the tiny amphibian's usual territory. Williams says the first frogs probably hatched from eggs that arrived in potted plants.

Williams tells the American Press (http://bit.ly/QNDncK) he didn't believe it when a friend said he could hear the frog in woods behind his home. After a year, he agreed to check. It took him less than a minute to realize he had a find.
