Spring and autumn are exciting times for anyone who watches birds. Here on this blog we will make predictions about when to expect migrant arrivals and departures, so that you know when and where to see these well-travelled birds.

Fair Isle mini blog: Resplendent Great Northern Diver

This, our fifth day on the island has had the feel of the quietest day so far. The thrushes that arrived on Friday have largely moved off, continuing their migration further south. Brambling numbers have also fallen and there seemed to be little evidence of migration. However, between us we have pretty much covered the whole of the island, and even though it is approximately three miles long by one-and-a-half miles wide it is no mean feat.

Despite there being no real indication of migration, the Hen Harrier have doubled from two to four, along with the Short-eared Owls, rising from four to eight. A small flock of Barnacle Geese headed south and four Whooper Swans visited the island briefly.

The surprise of the day was a full summer plumaged Great Northern Diver giving close views in the harbour by the observatory.

So what of the mystery warbler from yesterday? Despite extensive searching, it has not been seen again. Unless it pops up again over the next day or so it will be the one that got away.

The forecast for tomorrow is for gale force north-westerly winds with some snow and hail. We will have to don several more layers and go in search of any arctic waifs that might get blown this way.

Fair Isle mini blog: rain, rare ducks and a mystery warbler


Early this morning we received news that the east coast was experiencing a huge finch movement, with Goldfinch being the most numerous, flocks of 2-300 birds were being recorded, with smaller numbers of Siskin, redpoll and Brambling, also on the move.

The news came just after breakfast and before we had ventured out into the field; would there be an arrival of finches here too. It seemed unlikely, the small trees in the observatory garden were almost horizontal and the rain was definitely horizontal. Whilst most us headed out into what felt like an epic storm, two of the group had risen before dawn and headed out to the south light for a seawatch (John Marchant and Nick Moran). They must have been feeling pretty miserable by the time we had seen our first bird, a male Gadwall (a very rare bird on Fair Isle), actually they had been invited into the lighthouse for tea and cake whilst the rest of us had the biggest soaking of our lives.

The rare duck theme continued throughout the morning with the arrival of a Pintail, a female Scaup and two Velvet Scoter, joining the Shoveler from yesterday on this auspicious list.

Rare birds are what most birders come to Fair Isle hoping to find, but for most of us today didn't quite feel like a day when one might be found (Andy Clements excepted, he predicted the finding of a good bird just after lunch). Just after lunch Andy's prediction was realised when an Olive-backed Pipit was found in the garden of a croft in the middle of the island. This beautiful pipit breeds no closer to Britain that central Siberia, spending the winter in India; a very special bird indeed.

The excitement didn't stop there. Mid-afternoon saw Paul Stancliffe on the trail of a very skulking warbler that had been seen briefly amongst some cabbages. It was seen twice in flight and once running on the ground beneath the cabbages, and even though it was seen by the five observers present, it defied identification. Something to look forward to tomorrow.

Fair Isle mini-blog: Migration waxes and wanes


Even though it is mid-October and migration is at its peak, there are still days when nothing much seems to be moving at all. That was definitely the case on Fair Isle today, with generally fewer birds around, or so it seemed. The Redwings and Fieldfare were confined to the south-west of the island and had dropped in number. Despite the lack of anything moving overhead, there were lots of Blackcaps on the island and a few more Chiffchaffs. Brambling numbers have definitely increased, with Andy Clements and Rick Goater finding a flock of twenty-six birds in a oat crop in the south of the island.

New birds found today, included a tailless Barred Warbler (perhaps the result of a close escape with a local cat), a Shoveler (a rare bird here) and two Iceland Gulls. Nick Moran also added a Sooty Shearwater during a dawn seawatch.

Searching the dykes was very much the order of the day, with all of us getting very wet feet. We have been told to be careful not to get trench foot. Perhaps dyke foot might be more appropriate.

The forecast for tomorrow is for strong south-westerly winds and heavy showers, maybe the change in the weather will mean a change in the birds.

Fair Isle mini blog: an unexpected rarity


We awoke this morning full of anticipation, there had definitely been an arrival of birds yesterday and there must be more to find. On getting out in the field though it immediately became clear that a lot of yesterdays birds had left overnnight, or at least the Fieldfare had, numbers were down by half. However, as we moved further away from the observatory it also became clear that Snipe were everywhere where you might expect Snipe to be, a big increase on yesterday, there also seemed to be more Skylark and, for the first time Brambling were feeding in double figures and Snow Bunting trebled. 

Whilst this is a sure indication that winter is just around the corner, there are still summer visitors to be seen. At least two Whinchat, a Whitethroat, three or four Chiffchaff, including a fantastic grey and white Siberian Chiffchaff, and a small number of Blackcaps and Wheatears still give a taste of summer.

New birds in have included a Grey Phalarope, a Yellowhammer, apparently rarer than Lanceolated Warbler here, half a dozen Crossbills, a couple of Common Rosefinches and three or four Short-eared Owls.

The wind this morning was blowing very strong from a southerly direction and by mid-afternoon it began to rain, quite heavily by late afternoon, curtailing any further determined searching.

The rarity value today came in the shape of yesterday's Bluethroat, which only showed to a third of the group (PAS and Andy Mason), if you don't count the Yellowhammer, which only showed to the same third of the group.

The forecast for tomorrow is mostly bright with a few showers, and the wind a brisk south-westerly. It feels like there are still birds to be found.

Fair Isle mini blog: an awesome reputation

We all arrived on Fair Isle this morning after a 6.30am start and a fruitless search for the Buff-bellied Pipit. On stepping from the plane we were immediately greeted by a ringtail Hen Harrier and a large number of Redwings and Fieldfares, apparently fresh in today. There had only been a small number of these winter thrushes here during the previous week, which shows that things are now happening.

For  most of the day today it has been difficult to contain our excitement; it is Fair Isle in mid-October after all! We are here to experience migration and we have not been disappointed. Both summer and winter migrants are present. A Whinchat shared a fence with three Brambling at the island shop and just up the road from here was our first Yellow-browed Warbler of the day. The nearest this sprite breeds to the UK is eastern Russia. Although it is mid-October there are still a few warblers about and we caught up with several Blackcaps, two Chiffchaffs and a Reed Warbler, but none of these could beat the Blyth's Reed Warbler that was trapped and ringed early afternoon.

While there is still a taste of summer, the winter visitors outnumber the summer migrants and we found a flock of fifty Snow Buntings, several small groups of Bramblings, one Short-eared Owl and experienced a small arrival of Woodcock.

So even though we are here to enjoy autumn migration, Fair Isle has an awesome reputation for rare birds and it upheld this today. Alongside the Blyth's Reed Warbler, Common Rosefinch, Bluethroat, Little Bunting and Olive-backed Pipit were all found, unsurprisingly given the wind has quite a bit of east in it, all these birds have an origin from that direction.

As darkness falls the wind is still in the east - what will tomorrow bring - no doubt even more excitement.
