This line caught my eye in a story about the singing Pacific tree frog in yesterday’s Seattle Times: “If only everyone could hold a singing frog — it’s like holding the voice of spring in your hand.” Well, you can hold the voice of spring in your hand, when you’re holding your cell phone, because the Pacific tree frog is one of the fundraising ringtones you can download for $2.99 from the Amphibian Ark Web site.
