29th-30th May

Fog descended on the island, making visibility very poor at times. The 29th was fairly quiet although 79 Barnacle Geese were notable. Other migrants included 72 Knot, 2 House Martins, 1 Sand Martin, 1 Lesser Whitethroat, 2 Blackcap and 2 Chiffchaff. Things picked up on the 30th, with a Stone Curlew found in the fields behind Sangar early afternoon. A very rare bird in Scotland and the 2nd record for the island, it showed well and was still present in the evening. A few other good birds were about, with a female Red-backed Shrike at Ancum Willows, a Black-throated Diver on the sea by Bewan, and a Wood Sandpiper at Brides. Also seen were 23 Barnacle Geese, 8 House Martin, and singles of Tree Pipit, Garden Warbler, Willow Warbler and Chiffchaff. A Sparrowhawk and Kestrel were seen on both days as was the Corncrake at Holland.

26th-28th May

The weather has been mostly calm with some light south easterly-winds. Wader numbers for most species seemed to drop significantly, although 134 Knot on the 26th was the highest count of the year so far. Also seen that day were 2 Greenshank, a Peregrine, 8 Tree Sparrow and a Pied Flycatcher trapped and ringed at the Obs. 2 Black-throated Divers were in Nouster Bay, and were present there the following morning too. 2 Little Terns were on the Links on the 27th, and another Pied Flycatcher, a Siskin and 2 Lesser Redpoll were other birds of note. The highlight however was the first Orca sighting of the year, with at least two seen from Stromness Point. Another first for the year was a female Red-backed Shrike found at Trebb on the 28th. A few minutes later a summer plumage White-billed Diver floated past the seawatch hide. With a Black-throated Diver sighted at the Links later in the afternoon, along with 5 Great Northern and 1 Red-throated, it was the most diver species seen in one day on the island! Also recorded on the 28th was a nice male Ruff at Gretchen, 4 Sandwich Terns, 3 House Martin, 5 Chiffchaff, and singles of Willow Warbler, Blackcap, Spotted Flycatcher, Dunnock and Robin. A Sparrowhawk was sighted on all days as was a single Barnacle Goose on Garso, with another 4 at Nether Linnay on the 28th.  The Corncrake was still present at Holland, showing quite well at times.

24th-25th May

The winds didn’t look promising for migration, but there was a nice surprise on the afternoon of the 24th with a Red-breasted Flycatcher trapped and ringed at the Obs,  Apart from that though there was hardly anything else about, with 3 Collared Doves, a Chiffchaff and a late Fieldfare the only migrants of note. There was more to see on the 25th, with a Cuckoo found calling at Barrenha in the morning, and at Holland later in the day. A Grey Wagtail was seen on the beach at Nouster whilst a Black-throated Diver was in the bay. There were plenty of waders and seabirds about, with counts of 228 Sanderling, 69 Dunlin, 28 Knot, 350 Turnstone, 112 Gannet, 155 Great Black-backed Gull, 75 Kittiwake, and 400 Arctic Tern. A Barnacle Goose was at Garso, a Common Tern was seen from Laird's park, and 7 Tree Sparrows were in the fields by Holland. 3 Willow Warblers and 3 Chiffchaff were also present. The Corncrake was still at Holland on both dates.

22nd-23rd May

The weather went calm and sunny and it felt far more like summer was approaching than it did last week. On the morning of the 22nd an Osprey, presumably the one from the day before, flew past the Obs and headed out to sea, not to be seen again. The first 2 Tree Sparrows of the year were trapped and ringed at Holland, and later in the evening a flock of 14 were found amongst House Sparrows. 3 Garganey flying overhead were also seen from Holland. Other birds sighted included a Ruff at Cauldhame flash, 2 Kestrel, 5 Woodpigeon, 3 Collared Doves, 1 Dunnock, 1 Robin, 9 Sedge Warblers, 1 Blackcap, 1 Lesser Whitethroat, 2 Chiffchaff, 1 Spotted Flycatcher and a Lesser Redpoll. The 23rd was a much quieter day with the only birds of note 11 Sedge Warbler, 1 Lesser Whitethroat, 1 Garden Warbler and 4 Chiffchaff. The Corncrake was present at Holland again on both days, calling with increasing frequency and volume.

17th-19th May

Freezing winds and wintery showers made census unpleasant, but thankfully there was some good birds about. There were a couple of firsts for the year on the 17th, with a nice adult Little Gull on Gretchen and 5 Manx Shearwaters seen during a seawatch on the north coast. Another seawatch at the same place the following day was very successful, with a White-billed Diver showing briefly on choppy seas.  Also found on the 18th was an Iceland Gull at Nether Linnay, along with 14 Lesser Black-backed Gulls. A Wood Warbler was at Bewan, and 3 Chiffchaff, 2 Tree Pipits and a Spotted Flycatcher were sighted too. Wader numbers continue to rise, with 474 Turnstone, 141 Purple Sandpipers and 140 Dunlin counted on the 19th. Seawatching that day also provided high counts, with 254 Guillemot and 184 Puffins, along with 2 Common Scoters and 5 Manx Shearwaters. Migrants included 3 Chiffchaffs and singles of Collared Dove, Common Whitethroat, Blackcap, Spotted Flycatcher, Common Redstart and Lesser Redpoll.

Other migrants included 5 Common Whitethroat, 3 Lesser Whitethroat, and singles of Blackcap, Garden Warbler, Chiffchaff, Willow Warbler, Spotted Flycatcher and Common Redpoll.

 A juvenile Swallow born this year was amongst 8 caught at Holland in the evening. As no Swallows will have fledged yet in the UK this bird was likely born in the Mediterranean (where Swallows can start to nest in February) and has migrated north with breeding adults.

6th-8th May

Poor winds for migration resulted in a quiet couple of days with few birds about. 8 Whimbrel, 3 Chiffchaff and a Willow Warbler were the only birds of note on the 6th. On the 7th a flavissima Yellow Wagtail was seen at Brides, a subspecies rare here with flava and thunbergi much more regular. The winds turned south-easterly on the 8th and brought in more birds including some firsts for the year, Garden Warbler, Lesser Whitethroat, Common Whitethroat and Jackdaw. Also seen were 6 Chiffchaff, 1 Willow Warbler, 2 Blackcaps, 2 House Martins, 2 Siskin and a Sparrowhawk and Short-eared Owl.

4th-5th May

The southerly winds continued, which brought in some good numbers of birds. The 4th was relatively quiet, Arctic Terns rose to 202, and migrants included 5 Chiffchaff, 2 Robin and 1 Willow Warbler.  The 5th was a better day, with the first 2 Lesser Redpolls and the first Swift of the year recorded.

28th April - 3rd May

The last few days of April passed by with nothing of note at all, the persistent northerlies halting any migration. However, the winds turned southerly on the first day of May which brought in the first Arctic Tern of the year, along with 7 Whimbrel and a Short-eared Owl. The 2nd saw one of the highlights of the spring so far, a Rough-legged Buzzard that briefly showed well above Senness in the afternoon. A Long-eared Owl was at Ancum Willows and 13 Knot were at Westness. Whimbrel numbers rose to 20 and Arctic Terns to 55. On the 3rd the Buzzard made another quick appearance over Garso before disappearing south not to be seen again since. 2 Blue-headed Wagtails were found, one on the Links and the other at Hooking. A Short-eared Owl, 9 Swallows, 6 Woodpigeon, 2 Chiffchaff and singles of Blackcap, Brambling and Siskin were also sighted.
