I became fascinated with frogs soon after I moved to Highland Holler. It was hard not to – I’m surrounded by them here. There are green frogs, leopard frogs, pickerel frogs, wood frogs, toads, spring peepers – making a racket, hopping around, laying eggs, hatching into tadpoles, morphing into froglets and other such froggy business. But in this, my first frog-blog, I’m focusing on those heralds of spring: wood frogs and peepers.
I’m fond of all frogs but my favourites are wood frogs, first out of the gate in the great mating frenzy of spring. Wood frogs are amazing amphibians who can actually freeze solid during the winter – how cool is that? (Below zero cool!) They accomplish this astonishing act by flooding their cells with cryoprotectants, like glucose. When these frogsicles thaw out they initiate the spring singsong.
Wood frogs crack me up. These little fellas quack and cackle rather than croak, sounding like a coven of demented ducks. They can be quite vocal during the day. One sunny afternoon, soon after I moved into the yurt, I had the great good luck of watching wood frogs from my deck above the pond. The scene looked so idyllic, so serene, so blissful. Frogs were floating in their funny froggy way, heads above water, forelegs floating just below the surface, hind legs dangling. Basking in the sun … and then – bam! One frog scooted across the water and rammed into another from behind. The rammed frog dove to safety, replaced by his rival. Then they just all floated for a while. Until another frog abruptly turned torpedo and slammed into a floater. From my deckside view I could see a frog initiate his stealth attack and the ensuing amphibian collision.
Watching frogs play bump-em cars made for a very amusing afternoon, but I’m sure it’s serious business for the frogs. I presume (but don’t know) that this behaviour is the wood-frog equivalent of rams butting heads or moose wrangling antlers, i.e. males vying for females. The fellows woo the gals with their sexy quacks and then dominate their rivals by head-butting them out of the way. As with many animal species, it is the male frogs who sing (or peep, croak, quack, twang, snore, trill, and so on) to woo the females.
Spring peepers usually start in earnest a few days after the wood frogs. Spring and peepers are synonymous here in Cape Breton – there is even a ‘peeper report’ on our local CBC morning show where people call in when they hear the first peepers. (Gotta love living in a place with a peeper report!) As I related last month in the second verse of my Spring Ditty:
Well the other night I heard a little frog peep. No one replied so he went back to sleep. But the ice is melting and it won't be long 'til that froggy pond is filled with song!
And that is how it happens. Early in the spring there is the odd tentative peep followed by silence. I can’t help but think of these ‘early-bird’ peepers calling ‘Hey, anyone else awake yet?’ or maybe ‘Anyone else thaw out yet?’ – because these wee frogs can also freeze solid. But as the ditty relates, it isn’t long ’til that froggy pond is filled with song’ – and then what a cacophony! For a short interval there are wood frogs, spring peepers, and, in some years, a few American toads – each toad trilling his own unique prolonged note.
The wood frogs are the ‘first-to-arrive, first-to-leave’ types. They are pretty much finished just as the peeper party is really getting raucous. The peeper chorus gets louder and louder as more frogs join in until it’s deafening. Peepers are everywhere: by the pond, in the woods, in the grass and shrubs. They are tiny – not much bigger than a toonie. But their explosive peep is so loud that my field guide says it’s the equivalent of a human talking as loudly as a jet aircraft. I believe it. At times it literally hurts my ears to stand outside, especially at the pond’s edge. While I lived in the yurt, it was almost deafening inside, given the minimal sound insulation and the water so nearby.
While these wee frogs make one helluva racket, they are actually quite hard to find. They tend to clam up if you get too close. One night in the yurt I heard one just outside and stepped out with my headlamp on. There was Mr. Peeper in a plant-pot saucer. He froze mid-peep. His vocal sac was fully inflated, his eyes bulging (as frog eyes do) and he looked quite comical (as frogs do). I turned off my headlamp before he exploded. I’ve seen a few others – clinging to the vinyl yurt window, hiding in a garbage can, squatting between the slats of an old lobster trap – but for the most part, these tiny guys are heard, not seen.
At first peepers call mainly in the evenings, but soon the peeper party goes on all night long – rowdy neighbours! The annual chorus reaches its crescendo sometime in June and then gradually diminishes – I presume as the females choose their mates and they hop down to the pond to do it froggy style. (Want details? Search ‘amplexus’.). The party ends a bit earlier each night until one night there is just one last lonely peeper left. If there is something hopeful about that first tentative peep, there is something sad about the last peeper calling ‘pick me! pick me! pick me!’ long after everyone else has gone home. I know, I know – I’m anthropomorphizing. My imaginings probably have nothing whatsoever to do with frog reality. But I can’t help it. I always feel badly for this last little guy, peeping away all on his lonesome.
Now, at the end of May, the wood frogs are quiet but the peeper party is still going strong. A few nights ago, on the full ‘flower’ moon, I stepped outside into the unseasonably warm night. The moon, huge and low in the south, was a rippling silver reflection in the pond. The sound of peepers filled the air, accompanied by a trilling toad – the first I’ve heard in years. A barred owl hooted in the distance. It was a magical moment. At least for now, at least here in the Holler, the frogs are all right.
