Frogs hop on disclosure list

Real estate agents in Hawaii are including the presence of certain frogs in their property disclosures, the way that they already disclose termites and other potential hazards.

The coqui frog, a native of Puerto Rico, has multiplied in such proportions throughout Hawaii that its distinctive, high-pitched chirp has turned into a nuisance. Agents report that buyers disturbed by the noise level are backing out of deals.

The amphibian has a call that sounds like the beep trucks make when backing up, though more intense -- and the sound continues throughout the night.
