How I chuckled when I read your post! Here in Bermuda we have tree frogs galore! They sing us to sleep every night, especially when it rains! Tourists ask us what kind of bird sings at night here? Our little itty bitty frogs would fit on the top of your pinky finger nail, but their song will blast you out of your chair! Oh how I wish I could send an audio of our choir of tree frogs!
