How can I find out what is making the all-day-all-night noises in the water trenches near my garden? We have a creek on the property and a boggy area, and as soon as the snow melted, the creatures returned with their loud singing. I'd love to research to find out if it's a type of frog, what kind, how can I catch them to see them, etc., but I don't know where to begin. When I walk down to the garden, I can stare at the standing water and hear their loud noise, but I see no movement at all. And sometimes, when I approach the water, the noise stops and resumes as soon as I move away. Ideas?
