26th April 2017 Yell & Unst W2 Overcast

An ordinary start to the day seeing my first Carrion Crow of the year as I drove south through Haroldswick where there were also the first pair of Gadwall for the year sat in the bay and a flock of 27 Pinkfeet in nearby fields. The ferry trip to Yell took a detour to take a closer look at a superb pod of 14 Killer Whales heading west past Gutcher that we then followed to Cullivoe where the drake Scaup was still present. With the mid-afternoon onset of persistent rain I called it a day at work and took the 3pm sailing to Fetlar that then crosses to Unst. A few Great Northern Divers were seen on the way to Fetlar but then between Sound Gruney and Heogland on Unst I picked out a transitional-plumaged White-billed Diver. A flock of 18 Pinkfeet were seen at Buness House. Commuting to/fro work doesn't get much better than that!

24th April 2017 Yell & Unst W4

A snowy start to the day that soon brightened into quite a sunny afternoon. Yell produced a drake Scaup at Cullivoe and I finally obtained closer views of the Iceland Gull at Mid Yell. Back on Unst a Dunlin at Uyeasound was only the second encounter with the species this year and there was a Pink-footed Goose present with a flock of 20 then seen at Buness House. On the approach to Millfield there were 20 Redwings in a roadside field.

Juvenile Iceland Gull at Mid Yell
A very bleached individual only seen at distance on previous encounters but with a dark iris and pure white unmarked primaries it appears to be a juvenile.

22nd April 2017 Unst NW4

The 3 Brambling in our garden remain and were joined by a Chiffchaff today probably feeling out of place in the cold wind and frequent snow showers. A female-type Merlin zipped across the road near Baltasound and whilst driving near Buness House we chanced upon the first small flock of Eider we've seen off Baltasound this year. Whilst I am aware that the subspecies formerly known as 'Northern' Eider is now considered invalid by the BOU I've been looking for any individuals showing formerly published characters since I moved up here a year ago and today's small flock included a fine drake.

Drake Common Eider at Baltasound

Drake 'Northern' Eider at Baltasound
Showing the combination of hooked white scapular sails and both orangey-coloured frontal lobes and bill-base has previously been considered typical of S.m. borealis (e.g. see BW23 No.2 and here) albeit the recent rearrangement of  recognised North Atlantic forms is detailed here. The 2014 Dutch Birding identification paper places much emphasis on differences of nostril position.

20th April 2017 Unst W4 Overcast

A really quiet day when 3 Brambling in our garden easily proved the highlight. Otherwise 14 Pinkfeet were at the Heritage Centre and just a few lingering Redwing seen.

19th April 2017 Unst W2

Skaw produced my first Whimbrel of the year, a pair of Pied Wagtails, a few lingering Redwings and a couple of Chiffchaffs in one of the geos. A look out to sea from Lamba Ness produced my first 3 Arctic Skuas of the year that eventually virtually overflew me calling. Norwick was quiet with just a Goldcrest and a Brambling. On hearing of the Hermit Thrush on Noss I headed out to check some trees. No Catharus but an intriguing Gull in a field next to the Setters Hill pines, that I assumed was a hybrid Herring x Lesser Black-backed Gull.

Presumed Herring x Lesser Black-backed Gull hybrid at Baltasound
Click on some of the above images to enlarge. For images of a similar presumed hybrid see here. Some of the darker-mantled hybrids are apparently indistinguishable from Heuglin's Gulls. It appears to be a 4CY individual and published characters for Heuglin's including often showing just a single white mirror to p10, the black on the outer three primaries reaching the primary coverts, black subterminal band to the bill, some blackish tail markings, some outer secondaries showing limited dark centres, some vermiculations to the lower tertials and insipid leg colour could all equally apply to today's individual. There are images of an April 4CY Heuglin's Gull here.
