Snow and Corncrakes
Wild and windy last weekend which at last produced some skua passage – Arctic, Great, Long-tailed and Pomarine were seen from Ardvule.
A very busy week with a pretty diverse range of activities – chick chasing and nest recording, breeding bird survey, birding and late in the week joining in with a seaweed hunt.
I woke early on the 16th to turn off the moth trap – it was 4.30am and just starting to get light, the Blackbird was already on the lawn looking for worms. It felt very chill outside (especially as I was in me pyjamas!) and there was a dusting of snow on Ben Mhor, the overnight temperature had dropped to just 2.7’C and there were only two moths in the trap. So, a mixture of winter and summer as I could also hear a Corncrake crexing away not far in the distance. A single Hebrew Character (Orthosia gothica) in the trap
In just two days “chick chasing” produced 25 birds – all Lapwings.
The Oystercatchers are still sitting tight this week – surely they will hatch soon?
Friday 18th seemed like a good day to go and do the first visit on my Breeding Bird Survey (BBS) square – I can’t keep putting it off, the weather isn’t going to warm up! The 1km square is NF7841 and is fairly near to Loch Bee. A long fence line seemed like a good marker to follow over the boggy terrain – it was very soggy in places and I was really glad I had worn me wellies. Managed to see 25 species which quite surprised me.
At one point I was just about to climb a barbed wire fence when I spotted this spider on the wire. Now, I’m not much of a spider fan but our next door neighbour is, and even to my arachnophobe mind it did look quite interesting so I stopped and took a few photos. I believe it to be a Furrow Spider (Larinioides cornutus) which is an orb-weaver spider and looking at the NBN Gateway map has been recorded here in South Uist previously. They usually live near water and spend the day time in the “nest” that it makes.
I think I overdressed for doing the survey – I had a long-sleeved t-shirt, two fleeces and a waterproof coat on, trousers, waterproof leggings, thick socks and wellies – oh and my daft hat. I arrived back at the van absolutely sweltering! Maybe I’m just unfit?!
After the survey we headed off up to Berneray. We trawled across the machair to see if there were any chicks to ring, we only found 3 Lapwing chicks. There were quite a lot of waders on the machair – Sanderling (seemed weird to see Sanderling on a ploughed area!), a handful of Black-tailed Godwits, Then we headed up to one of our favourite spots right up in the north of Berneray where you can sit on the top of the dunes and look out across the Sound of Harris – on a nice day we sit out on the picnic chairs – today wasn’t one of those days! Great view though and there was still snow on the Harris hills
The first juvenile House sparrows were seen in the garden on the 19th May
We always like to learn about something new so when Curracag (the local Natural History Society) advertised an event to be run during Scottish Biodiversity Week we thought we would go along. It was called The Big Seaweed Hunt and took place at Carinish, North Uist.
Even for someone who is supposed to be grown up there’s nothing quite like splashing around in the rock pools in your wellies is there!? The event was well attended and there were a good range of ages – right from toddlers to oldies – well Ian does have his bus pass now
All this fun had a serious side to it – we learned that seaweeds are “simple plant-like organisms called algae” and that many animals rely on them for food and shelter. We also learned that, rather worryingly, and in common with many other plants and animals, seaweeds are responding to climate change and rising sea levels. There is an invasive species called Wireweed – it was first recorded in 1973 in the Isle of wight and has been gradually spreading north.
Before going along to this event I knew absolutely nothing about seaweed and didn’t realise the diversity that you could find in just one very small inlet. We found at least 6 different species plus a few more unidentified species which Tracey (who led the meeting) took home to identify. The 3 most common seaweeds there were Egg Wrack, Bladder Wrack and Channelled Wrack.
We left the meeting fairly well enabled to be able to survey our own chosen patch of beach so that we can now take part in our own Big Seaweed Search – the results of which we will be able to enter on their website at: www.nhm.ac.uk/seaweeds Take a look at the web site it has loads of information both about the survey and seaweeds in general. I also found quite a handy (if a little technical) key in the Field Guide to British Seaweeds found on The National Marine Biological Analytical Quality Control Scheme website.
Moth trapping has still been very dire – the cold northerly wind continues and the only night it turned south-easterly we caught just 2 moths – a single Red Chestnut and a lovely Pebble Prominent (almost four weeks earlier than our first one last year).
On the 20th we caught and ringed our first Oystercatcher chicks of the year – I tell you what, for something so small they can’t half run fast!
And we have now ringed 100 Lapwing chicks this year – this morning (20th May) we found two broods of four, including these that were still in the nest, they looked like they had not long hatched (you can just about make out the egg tooth on one of the chicks bills)
