Windy sea cliffs

A small section of a colony of Kittiwakes Rissa tridactyla 


A few days ago the weather was forecast to turn windy and wet, so I took a day out to visit the seabird colonies on the north-east Scottish coast, where the rain would reach last. I timed it right and I had a great time watching the birds flying in the wind, the clifftop giving me an eye-to-eye view of them in flight. So different from standing low on land or a boat looking up and only seeing their bellies.

Windy days are also best for watching and photographing them as they often stall and hold themselves stationery in the wind, without any need to flap their wings. From my high perch, I could see how the wind ruffled and tugged at their feathers, flight is obviously not always smooth.

Most of the birds were holding their feet down, using them as extra aids to flight in strong wind.

A Fulmar similarly flying with its feet down


The truly specialist fliers on these cliffs are the Fulmars Fulmarus glacialis. One minute, they would cut through the wind at high speed, the next they would float up on an updraft, holding themselves in one spot by the slightest of flicks of wing, tail or feet. They seemed to be inquisitive and deliberately approached me as I sat on the cliff top, watching me eye to eye before slipping off on the breeze.

The dull grey skies gave low light for photography, limiting the speed I could shoot at, but the positive aspect of the low light was the colour saturation I could capture. Photographing seabirds on sunny days can be very tricky as most of them are black and white. Under bright light it difficult to capture the details of their plumage due to the sharp contrast. The light was growing darker as the clouds thickened, but I managed to grab some shots that showed the feather details; how they lie when in flight, the different shades and colours of the fresh and old feathers, the smudges of dirt and guano on their breasts, and the fine lines on their faces, bills and feet.

Every cloud has a silver lining.

It's not easy for seabirds to keep clean when they are nesting on dirty ledges

Scottish summer summary

Walking over the tops - ptarmigan and dotterel habitat

It's now late July and I am back at the desk after my annual working tour of Scotland. Time to catch up with write ups and organise photographs. This was a quiet season for me as I had pinched a nerve in my spine in January and the sciatica is still hurting, curtailing any climbing, running and jumping. Fortunately a friend, Simon Cherriman, from Western Australia was also over in Scotland while I was there so we teamed up and I showed him around a few places and some of the special wildlife that abounds in such a small country.

While up on the high ground looking for ptarmigan we came across this Mountain Leveret

First of all we went and surveyed my long-term study site up in the hills for Ptarmigan. Their numbers vary between years following a cyclic pattern, and this year their numbers were low with only three pairs in the core area. But there were numerous Mountain Hares which was a welcome surprise. For these animals are being relentlessly killed on some estates managed for red grouse shooting in the belief that they carry parasite and act as a vector for disease in grouse, leading to fewer grouse to shoot. Such a selfish attitude at the cost of these animals which the majority of people visiting the Highlands in search of wildlife would so much like to see.

These three leverets were hiding in one form,
unusual behaviour as the mother usually leaves them in separate forms for safety 

A visit to the bird cliffs is always a tremendous experience
 - Simon rather enjoyed himself

Our next day passed quickly when we went to the sea-cliffs. The smell of guano mixed with the scent of Thrift had to be smelt to be appreciated, so so, different from anything else. 2014 was a splendid year for blossom of all sorts, but for now I'll concentrate on the animals. That day was definitely for the birds, thousands all around us and we must have fired off thousands of shots between us trying to capture the perfect shot of the birds in flight.

A Fulmar cruising past, most shots were out of focus, out of frame or wrongly exposed - hundreds of them


Simon adds colour-rings to a Redshank chick with Raymond Duncan

We spent most of our time based in the north-east and much of the field time ringing wader chicks with members of the Grampian Ringing Group, mainly with my brother Skitts, Ewan Weston and Raymond Duncan. Simon is a trainee ringer/bander in Australia, but has no experience of ringing wader chicks, or any other chicks for that matter. So he gained full-on intensive training from some of the most experienced bird ringers, not only in Scotland but the world.

One of the jobs I had to do was find and fit Greenshank with geolocators as part of a study of their migration being organised by the Highland Ringing group. So we spent a couple of weeks in the far north doing that with Nick Christian and Brian Etheridge. That wasn't all we did there though, as there were so many other birds around us in that stunning landscape, but that has been covered in previous posts. And it would take too long to tell here.

The same Greenshank chicks

We ringed various birds during our travels, and as it was springtime most were chicks. They ranged from tiny Willow Warbler nestlings, Redstarts, Skylarks, Meadow Pipits, Pied wagtails, Common and Black-headed Gulls, Kestrels and Common Buzzards, etc. One rather different brood we ringed were Barn Owls which were in a nest in the roof space of an old ruined cottage.

There were five owlets squeezed between the ceiling and the roof

But it was when we had trees to climb that Simon earned his living. As I had hurt my back I was reluctant to climb some of the trees to reach various nests, but Simon is a superb tree-climber, probably the best I have seen. He had timed his trip to Scotland perfectly. I helped him and he helped me - all happy.

 - a similarity noted by Mick Marquiss as Simon skipped up a tree
 so like the film character with his dreadlocks and camouflaged gear

Simon, like all of us who climb these trees, really enjoyed the thrill
 and atmosphere of climbing ancient Scots Pines

We helped Skitts and Ewan ring Golden Eagle chicks at various nest sites which they monitor annually. Ewan and Simon would climb the trees, lower the chicks in a bag down to the ground, where they were ringed and measured safely, then they we would pass them back up. Some of these nests are over a hundred years old, in trees that are several hundred if not thousands of years old. And some of these eyries are big, really big. Who wouldn't be impressed by such an experience.

- even he, at two metres tall was dwarfed by the eyrie

Simon studies Wedge-tailed Eagles in Western Australia, so he was perfectly at home and adept at handling the Golden Eaglets. Although they can be big strong birds and they can be in a potentially precarious setting, mixing tender careful handling with confidence ensured slick procedure.


Talking to eaglets always helps - it might not calm the the birds,
but it does calm the handler and helps the work go efficiently 

And that was what I did in Scotland 2014, well a little bit of it, there were also Arctic Terns, Golden Plover, Dunlin, Woodcock, Sparrowhawks and....  Thanks for all the help Simon.

Seabird flight

Two Kittiwakes soaring over the sea
While visiting some seabird colonies on the Scottish coast recently I took a few images of the birds in flight to capture their comparative morphology and technique. For each has its own, which fits the species' life.

Herring Gulls have a heavy appearance 
Herring Gulls, like most gulls are more land birds than seabirds, for they forage onshore, often well inland, as much as at sea. Even when at sea they mostly inhabit coastal waters. So these birds have a generalist type of flight; they can soar and they can flap with deep strokes. They are recognisable by their strong, bulky body and thick set appearance.

Kittiwakes have a straight edged tail and bent wings even when gliding
Kittiwakes are true oceanic gulls. They are light buoyant fliers, only coming ashore to rest or nest. Most of their lives are spent foraging out at sea, where they glide, flutter and dip into the surface waters for food. These are delicate gulls, recognisable by their slender build. It is not so much their colouring or markings that identify them, but their agility and knack of switching from a long oceanic gliding flight to a tern-like fluttering dance, with their legs hanging down as they dip for food.

Fulmars have rounded tails and their wings are held rigid most of the time when flying
Fulmars are true seabirds. They spend most of their life on the wing, gliding on stiffly-held wings as they flip low over the waves. And they seem to fly more easily the stronger the wind. They might be clumsy on land when they come ashore to nest, waddling on their short weak legs as they scrabble onto their nest ledges. But those short legs are suffice for their purpose, when out at sea, they are an advantage, as they are tucked into the body feathers and never hinder the birds' aerodynamics. The whole bird is a slick flying form, using the wind for lift and thrust, and they are a delight to watch as they wheel around and around the airspace off the nesting cliffs.

Fulmars, like all petrels and albatrosses are true masters of oceanic flight
I have not mentioned the auks or shags which also breed on the Scottish coast, for they are more swimmers that fly, than flier that swim like the birds listed above. The auks' and shags' forte is their diving ability - they swim underwater.
