Croaking Boreal Chorus Frog

Posted just for the record - and because it makes me smile, remembering how much noise these very tiny Boreal Chorus Frogs make. They sound very much like someone running their fingers along a comb, over and over again. There is a temporary patch of water near the pathway in South Glenmore Park and we stopped to see if we could see even just one tiny frog. This one was eventually cleverly spotted (photo is 48x zoom plus cropped) and I caught it in full croak : )

"Alberta’s smallest frog measures a mere 2 – 4 cm. It varies in colour from dark brown to green with three dark stripes or lines of broken spots on its back and a white upper lip. It is more often heard than seen and the males mating calls in spring are quite loud. Their trill is similar to the sound made by dragging a thumbnail over
the teeth of a stiff plastic comb. Breeding occurs between April and June, with males calling as soon as ponds are
ice-free."
