It’s been one of those weeks when spring can’t decide if it’s coming or going. One minute, you’re too hot with your jacket on. The next, you’re rummaging for hats and gloves and cursing the weather gods. And it’s not just the reserve staff who don’t know what to do with themselves in this weather – some of the plants don’t, either. Celandines are the ultimate sun worshippers in early spring: on a fine day, the grass is studded with cheery yellow flowers, all turning slowly to follow the sun across the sky.

But they were in for a shock on Thursday. A hard overnight frost took us all by surprise and, first thing, they were firmly closed to protect their precious petals from the biting cold.

For early-emerging insects, a hard frost can be fatal. We’ve only just started to see butterflies and bumblebees in the past fortnight, and this small tortoiseshell butterfly was the first we’d seen actually on the reserve. It looks surprisingly fresh, given it will have overwintered in a shed or pile of vegetation. Let’s hope it found somewhere sheltered to spend the cold and frosty night.

The cold, north-westerly wind has also put a bit of a halt on migration. While animals are on a clock to get north and breed, a head wind is extremely unhelpful. Many birds will pause in their migration so they don’t burn up too much energy battling into the wind, waiting instead for a break in the weather before making the perilous North Sea crossing. This chiffchaff was probably doing this, pausing to feed until the wind dropped, then moving on under a still, starry sky.

Even the tufted ducks and wigeon on the Sand Loch, all of whom were displaying furiously on Tuesday, had given up on the idea by Thursday. When it’s still (which it hasn’t been very often of late), you can sometimes hear the tufties ‘bibbling’ enthusiastically at one another, trying to impress the females. Whom, I must say, tend to look overwhelmingly unimpressed by the whole performance.

The wigeon, meanwhile, had given up on the whole idea and were keeping their heads down in the sheltered drain at the north end of the loch. It was clearly too cold for them to get amorous, so they were concentrating on eating as much in the way of pond plants as they could.

All in all, the weather hasn’t been doing any of us many favours this week. On Monday morning, we were greeted by the after-effects of the weekend’s gales at the ternery. Our carefully-erected predator-proof fence has sadly not proved weather-proof and quite a number of repairs were needed. It’s definitely a good job you can’t hear what we were muttering in this picture!

The fence will be needed very soon. By Thursday, 34 Sandwich terns had arrived back and we’ve seen the first pair displaying over the colony, dangling a fish and soaring high to prove their fitness. They’re basically saying to one another, “Look at me, I’ve got a fish – aren’t I clever – I’d be a great parent for your babies!”.

The black-headed gulls are also going to need the fence, and a lot sooner that the ‘sarnies’. There must have been over 1,000 birds in the colony this week, and we’re expecting (or maybe ‘egg-specting’?) the first eggs any day now.

Gulls in general get a bad press, but they are actually very handsome birds. We’re very fond of our ‘headers’ here and they are looking at their best now, at the start of the breeding season. With their smart chocolate-brown hoods and cute white ‘eyeliner’, they are attractive and engaging birds. Given that we can have up to 20% of the whole Scottish population nesting within the protection of our electric fence, we need to make sure we keep it in good working order.

While the fence is generally pretty good at keeping out foxes and badgers, we were surprised and concerned to find the prints of American mink near the ternery last week. Thanks to the great work done by lots of fishery boards and our friends at Scottish Invasive Species Initiative, mink are very rarely seen on the Ythan these days. However, upon spotting these prints, we hastily got in touch with SISI officer (and former Forvie seasonal warden) Robert, who supplied us with a mink trap. He told us two mink have been caught locally in the past fortnight, so it may be that ‘our’ mink is no more, but with an internationally-important colony of breeding birds to protect, we can’t take any chances.

With the advent of the 1st of April this week, we have also put up our ‘barrier fence’, and the south of the reserve is now closed until the terns and gulls have finished breeding. As always, we greatly appreciate everyone who respects this. We also greatly appreciated the help of our crack volunteer team in getting the fence up. Our ‘usual’ beach vehicle access from Rockend has been cut off by sand movement, so this meant we had to carry all the poles and equipment from the estuary side to the beach. This is extremely hard work as you’re carrying a heavy load over more than half a mile of soft sand. It was a tough day to start back for seasonal Joe, whom we’re delighted to say is rejoining us for his third season. Welcome back!

But, after a hard morning of calf-and-thigh-aching trudging through the sand, we had the fence up. As always, we owe a huge debt of thanks to the team for helping us out – we genuinely couldn’t do it without you.

So, that just about wraps up another week on the reserve. I’m off to vainly attempt to empty that sand out of my boots. See you next week!
