We don’t usually have to wonder too much about the wind direction – the Dark Island turbine and the fishing boats, when in the bay, give us all that without us even having to step outside. Consequently it’s a rare day when the wind is so still that the boats point in different directions (even if the above photo, taken yesterday afternoon, was taken just about an hour after low tide with the boats being still somewhat stuck in the sand). Today, again, there’s barely a breath of wind.
To tell the truth, the weather has been extremely poor in June, with cold grey skies, plenty of rain and strong winds for much of the month until its last few days: a clutch of tourists arrived at our door on Wednesday last week, in search of a neighbour’s B&B, clad in shorts and light summer jackets; a few hours later they were spotted on the way back from the beach in heavier coats, long trousers and holding to each other for warmth. Our fisher folk have indeed rarely ventured out – not so much the weather in June itself as the lingering effects of our long, cold winter on the size of the shellfish, typically lobsters, that they usually catch: shellfish are simply too small to warrant the effort, and the dangers, of going out and bringing them ashore.
I alluded to this below in the late return of the corncrakes, given the lack of cover provided by the nettles and yellow flag iris – one male was still calling yesterday afternoon, somewhat forlornly, although most females will be on a second brood by now so there’s little for the males to make much of a song about. There is now, at least, plenty of cover for them on the land: June’s rains have seen the nettles and the iris spring to life and it’s likely that their nests – the second ones – will have remained well hidden. Worse effects seem to be on the birds which can be predated upon and whose nests are more in the open: there is so little seafood to go around that the gulls – not so much the ravens this year, which are remarkable absent from our headland – have turned to the bird populations instead, and with catastrophic effects: a pair of shelduck popped up one day last week with a brood of 8-10 ducklings but I caught sight of a pair, probably the parents, on Saturday evening, just drifting on the tide, distanced but sorrowfully together, and entirely duckling-less, before taking off together toward the setting sun. There is no eider nursery that I’ve seen: parent birds, now moulting and looking in pretty poor condition, but entirely duckling-free. And a lapwing nest on a neighbouring croft was taken by gulls over two days last week: on the first day the parents were mostly successful in driving the gulls off but a determined one returned to polish off what was likely to be a solitary remaining chick the following day. Again, the parents – after making a quick, but vain, attempt at defence, swooping fast from the air at the gull(s) on the ground – flew high up, parted and then away separately into the skies.
The fishing season will pick up, even if the autumn gales ensure that it finishes more or less at the same time as usual, leaving (probably) a much truncated season behind; but it is too late for those breeding birds whose clutches are solitary and whose breeding window, in many cases, is brief enough. Despite the effects of our own activity, nature is largely balanced and self-regulating: a poor season one year is still likely to be followed by a good one the next. In the long-term, however, a repetition of long cold winters as a result of climate change will spell trouble: as resistant to long-term change as we humans can be, we tend nevertheless to greater adaptability in the short-term in the face of the havoc we are causing. There will be other jobs on the crofts, with crofters tending each to have three or four jobs anyway. But, while the survival urge will prompt its own changes in response among wildlife populations, unless they are also able to do so in the same short time frame, devastation will be the result. This tension between long-term and short-term adaptability, between humans and wildlife, lies at the crux of the problems being wrought by climate change.
