I heard the frogs before seeing them – a pulsating, rhythmic hum that ebbed and flowed across the afternoon air. This frog chorus was hypnotic and alluring, and accompanying their gentle croaks were the rougher ‘qwark-qwark’ calls of mating toads.
I was on the approach to a remote hill pond near my home, which I had only discovered a few months previously during deepest winter. At the time, I reckoned the pond looked the perfect place for spawning amphibians and now it transpired that my hunch had proved correct.
Not wanting to spook the frogs and toads, I crawled slowly towards the pond edge, a few short pulls of the arms and legs, then a short pause, followed by a few more. When close to the pond, some of the frogs and toads cavorting on the water surface spotted me and in a sudden swirl were gone. Non-plussed, I bided my time and soon their heads popped up and the air filled once more with their resonant calls.
This was heavenly paradise, nature in the act of procreation and the water continually rippled as the males vied for females, sometimes clambering on top of their backs and gripping tightly in the mating embrace known as amplexus.
Strangely, I had never previously seen frogs and toads together at the same time when mating. Normally, frogs spawn in early March with toads following a few weeks later. However, this was the earliest in the year I had ever seen toads active on a breeding pond, which in turn had resulted in the overlap with the frog spawning and was possibly a worrying sign of climate change.
In another bizarre twist, on some occasions male toads crawled onto the backs of female frogs as if to mate with them. A case of mistaken identity no doubt, but I did briefly ponder the seemingly implausible notion that frogs and toads might have the potential to interbreed and hybridise. It is an occurrence I have never heard of before and quickly dismissed it from my mind.
As I watched the amorous amphibians, a pair of grey wagtails alighted on the far side of the pond, and darted around snapping up tiny flies, before spiralling away again in an undulating flight.
After an hour or so, it was time to go, but on slowly turning my body, I came face to face with a writhing ball of toads on the grass behind. A poor female toad had attracted the attention of two males, both of whom gripped tightly onto her back. She slowly crawled along the ground with her unwelcome cargo – a ponderous and energy-sapping process. Would she be able to shed one of the males by the time she reached the pond, or would she have to endure both for several days to come?
With such pressures, it is hardly surprising that many toads succumb at this time of year – it may be the season of renewal, but the dark cloud of death is forever present.
