A dark day in the sun
The heron ate my frogs.
Not “a heron”, but “the heron”. In Ireland, serious threats are accorded the definite article: the fox, the blight, the whooping cough, and — on that fine day last spring — the heron.
Or rather, it was a fine day for the heron, but not so for the frogs. They had already had a stressful year. Spring had come early, and gone away again. January was so mild that the frogs had spawned on the 7th (the earliest date yet in my twenty-one-year stint in this garden). They spawned again at the end of the month, and then, spring retreated and winter blew back in with flurries of sleet and snow.
When spring finally reappeared in March, they were in the pond again — glorious, tumbling bundles of fornicating frogs. I left them to their work, undisturbed by my camera. After the difficult start to the year, they deserved some privacy and peace.
The heron thought otherwise.
My phone rang. It was a neighbour: “Are you looking out the window?”
No, I wasn’t (for once).
“There is a huge bird eating the frogs — like a crane or something. It’s amazing!”
I was torn: should I reach for my camera, or should I shout at the dogs to scare off the intruder? A quick look out the window revealed that it wasn’t a crane (a very rare visitor to Ireland), but — as I suspected — a grey heron (Ardea cinerea), the largest heron in Europe, which is native to Ireland, Britain and much of Europe and to parts of Asia and Africa. My glance revealed also that it was too late for the frog, dangling darkly from the bird’s brutal bill, so I grabbed the camera.
I felt like a traitor towards the amphibians with whom I had shared many summer afternoons by the tiny pond, but I wanted the picture. I am, after all, keen on wildlife, and here was wildlife — and wild death — happening right in front of my lens. Still, I felt affronted and angry. I had nurtured the frogs, thinking of them as “my” frogs, although they were nobody’s frogs but their own. But now, it was apparent, they were the heron’s.
The frog that was in the heron’s bill, and that would soon be in its stomach, was old enough to breed, so it was three or four years old. What a way to go. One minute in the throes of reproduction, and the next in the jaws of death.
I moved closer and closer to the heron. Was there a touch of annoyance in its golden, predator’s eye? Eventually, it unfolded its massive wings and flapped off to perch on a tree in a neighbouring garden, the frog still hanging from its bill.
It swallowed it whole (and still alive?), and moved to the top of a swing set, perhaps contemplating its next move. Would it be able to cram in another frog? It was the heron’s own breeding season, so perhaps it was stocking up on food to regurgitate later for its chicks. A magpie arrived, sat next to it on the wooden bar, and then dive-bombed it several times. Maybe the magpie, a ruthless predator itself, was worried what might happen to its future offspring if the heron got too comfortable in this place.
The big bird came back to rest on the wall of my garden, but I saw it off too. I felt mean scaring it away, but it had already helped itself to several frogs. I thought it would probably be back before I managed to get some netting for the pond.
And indeed it was: a while later it was swishing its yellow bill around in the weedy water, as if stirring a pot of porridge. After I had rigged up an unlovely wire grid over the pond — with room for songbirds and frogs to scoot under — the heron returned several times, puzzled at this barrier to its food source. It sat on the greenhouse roof (where it made a striking finial ornament), waiting to see if the wire mesh might somehow disappear. It didn’t. In making the pond inviting for the frogs, I felt I had a duty of care for them. The heron, I decided, could go somewhere else.

I’ve been in full voyeuristic mode recently: peeping out of an upstairs window with binoculars, and then, when the moment is right, rushing out the door. My camera is raised in the shooting position as I barrel down the steps and I’m firing it off rapidly, papparazzi-style. But, mostly I’m drawing a blank. Or, if I’m lucky, getting something like this:
Which is nice, because it’s always cheering to see photos of frogs lolling around, nonchalantly taking the air. Or, I might get something like this, which is also nice, because it’s arty and amusing, and it gives you a warm feeling about this particular character:
What I’m really after, though, is a good, juicy photo of frogs mating. But that’s not easy. Although there are at least two dozen amphibians making whoopee in our tiny garden pond, they are desperately shy. Oh, I can see them bashing away and the pond rippling like a bubbling cauldron when I’m at a safe distance. But as soon as I get within a few paces, there is a split second of furious detangling and rapidly churning water. And then, they’re all gone. Except for a few innocent heads poking out of the water.
Frogs are impossible to sneak up on. Their bulging eyes give them near all-round vision. And our pond is not the most secure place. While crouching behind the Bergenia ‘Wintermärchen’ and hoping to get a better photo, I am assailed by an eye-stinging pong of fox urine. Our neighbourhood foxes, I imagine, are partial to the occasional frog dinner, and have been patrolling the garden more than usual.
So, I decide to leave them in peace and to sit a while where they can’t see me, and I can’t see them, but I can listen to their fluty croaking. Actually, the sound they make is far more melodic than a croak. It’s more a soothing, sonorous purr.
For me, watching the frogs may be entertaining and thrilling, but every year, after trying yet again to get photos of them in flagrante, I have to remind myself that this annual mating spree is a crucial part of their lives. Each female Rana temporaria produces around two thousand eggs, and she may mate with many males (often several at a time) in a process called amplexus. But only a few of her blobby eggs will reach adult froghood, three years down the line. Along the way, most of the tadpoles will be eaten by other water dwellers, or even each other (a gruesome sight to behold when you’re idly gazing into the depths of the pond). And baby froglets — no bigger than a pea with legs — perish if they can’t quickly reach a nearby cool and leafy sanctuary when they first venture out of the water.
So, I’m hanging up my frog-shooting camera until next year, when I’ll probably try again. My best bit of spawnography yet was taken two springs ago. Here it is, an uncommonly busy bundle of common frogs.
