27th April – Guillemots

There are many evocative sounds in the Highlands such as the roaring of red deer stags in the Autumn. Seabird colonies of auks such as guillemots in the middle of the breeding season may be raucous as their calls echo round the sea cliffs but it is still very impressive. In the last two weeks greylag and pink footed geese have been heading north to their wintering grounds in Iceland and beyond. Their calls seem to epitomise the colder wildness where they will breed but despite the loud calls in flight they can sometimes be difficult to actually see. Of all the evocative sounds perhaps none is more so than the bird displaying in the glens, straths and moorland of the Highlands at present, namely the curlew.
The call notes have been described as “an eerie lamenting cry” and have given rise to a great deal of superstition. The mournful notes led many to say it signified death but others were far more stimulated in a much more positive way. Norman MacCaig who stayed in Lochinver wrote a poem in March 1987 entitled “Curlew” that contains the lines “trailing bubbles of music/over the squelchy hillside/Music as desolate, as beautiful/as your loved places./ Mountain marshes and glistening mud-flats/by the stealthy sea”. The very wide range of local, Scots and Gaelic names is typical of many others birds that were shot for the pot. The plumage of the adult curlew is darker in summer than in winter hence the Scottish proverb ” Be she white or be she black/The curlew has ten pence on her back”. Curlews were much prized in the old court banquets and it was not many years ago that they could still be shot. It seems to have been an acquired taste especially after it had been feeding in the winter in the mud of the firths and the foreshore.
Curlews have an unusual breeding cycle and as they nest on the ground they suffer from predation by a wide range of predators such as fox, mink and crows. The male makes several scrapes and it is the female who decides which one will be actually used and then she alone lines it. The nest is mainly in the open on a mound or tussock but sometimes protected by vegetation. Both parents will incubate the eggs but this falls mainly to the female. Once the chicks have hatched and are active the female leaves with only the males tending them before they fly to the coast.
The curlews calling in the Highlands are birds that will have come back from their wintering grounds in southern Britain or Ireland. The males move into the territories first and wait for the females to arrive. Curlews have had to adapt to changing land use and it is now difficult to imagine it was not too long ago that they were confined to upland areas whereas now they breed down to sea level. Overgrazing and over burning may have forced it to breed at lower altitudes but in recent years such areas have not been ideal. Changes in the times that grasslands are cut has adversely affected curlews that are now classed as on the “amber” list. This means it is of “medium conservation concern” as opposed to the “red” list which means of “High conservation concern”.

20th April – Rosemarkie on the Black Isle

The stretch of coastline east of Rosemarkie on the southern edge of the Black Isle has a wildlife quality of its own and scenically is one of the most attractive areas around Inverness. Car parking is near the outlet of the burn falling from the Fairy Glen and there is a path leading east to the famous Scart Crag locally known as Scart Craig. The cliff is about one and a half miles from the parking and the white washed cliff is the result of generation of cormorants droppings. “Scart” is one of the many Scots names for a cormorant. The path runs through woodland, scrub and dunes that have been stabilised with marram grass, and all the way the cliffs on the landward side vary in steepness and size. Buzzard nest in the woodland and the birds can often be seen hunting along the coastline for rabbits for their chicks. At one point there is the finest array of rock pools in the eastern parts of the Highlands and they support a wide variety of wildlife from crabs to anemones and sticklebacks to shell-fish.

The dominant seabirds are the fulmars that are present almost all the year round and nests in a small colony on the edge of Rosemarkie. How strange to think that before the end of the 19th century the only British colony was on St. Kilda. Now fulmars glide along the cliffs by the firth or low over the sea seemingly effortlessly with only an occasional wing beat. Scart Crag and the surrounding cliffs once supported herring gulls whose eggs were much favoured for eating by local people. They were not the only predators as sometimes, even during the day, foxes and otters could be seen raiding their nests. The gulls no longer nest there but other birds have taken their place and in the last couple of years a pair of ravens have nested there, the first time for very many years on the Black Isle. A much smaller bird and in a way much more surprising is a colony of house martins first located in 2004.

This is one of the best places around Inverness to see butterflies and the speciality and a great rarity in the Highlands and beyond is the northern brown argus. Its caterpillars feed on one of the most attractive of wild flowers, the common rock rose. It is one of the smallest of the butterflies being dark brown with a tiny white spot on the fore wings and the adults are still on the wing at this time of the year. Other butterflies include the small copper, grayling, common blue, pearl bordered fritillary, dingy skipper and speckled wood. The reason for the abundance of butterflies is the wide range of wild flowers that give the butterflies a nectar source. These include bloody cranesbill, wood vetch, stonecrop, hemp agrimony and dyer’s rocket.

If the tide is out then waders such as oystercatcher, curlew and redshank will be feeding in the mud and sand whilst the beds of mussels and winkles may well have a few of the very well camouflaged turnstones with the occasional purple sandpiper freshly arrived from their breeding grounds in Norway or Iceland. On the sea at this time of the year are red throated divers that have bred on hill lochs, red breasted mergansers and goldeneye. What often steals the show, however, is not the birds but the sea mammals and there is always a good chance of seeing grey and common seals especially when the fish are moving with the tide and the seals are feeding. To many, even more exciting, are the resident numbers of bottle-nosed dolphins that are now famous and much admired from boat trips organised especially to see them.

Ray Collier Country Diary- Coal tits

13th April – Coal tits

The coal tit is one of the smallest birds to be seen in the Highlands and it has a short tail and a rather large head. The head is black with white cheeks like a great tit but the diagnostic feature is the large rectangular white patch on the back of its neck. The back, wings and tail are a dull blue grey and the underparts are plain and buff. At close quarters the two wings bars on each wing are conspicuous. A young bird has yellow cheeks, nape patch and underparts and they moult before the winter. However the yellow wing bars of the young birds do not moult until the spring so they can be identified throughout the winter months. They are the smallest of the British tits and they weigh between eight and ten gms so most of the birds weigh less than a one pound coin.
Until recently coal tits were considered to be mainly woodland birds, both conifers and broadleaves. They seem to adapt to conifers more than other tits as they have the ability to hang upside down and feed which means they can take food from under twigs covered with a layer of snow. They also have very thin beaks which means they can get into crevices for food that other birds have to ignore. These days they are a common garden bird as they readily adapted to food being put out all the year round. In some gardens in and around Inverness they are now commoner at feeders than blue tits. Studies have shown that despite their tiny size they do not suffer as much as some other birds in short spells of bad weather as they store food when the weather is good. Coal tits are one of the birds that have flourished in the huge areas of conifer plantations in the Highlands and they are now widespread.
In gardens these tiny birds are more often than not at the bottom of the pecking order but they cope with their speed and agility. Peanut holders such as the one in the photograph are favoured but the feeders taken to more than any others are those with sunflower seeds. The seeds are small enough for the birds to fly in and quickly take one and fly off to store it and then back at the feeder in a very short time. In the winter they are gregarious with other small woodland birds and will join in bands of other birds such as other tits, tree creepers and goldcrests. These flocks will move through woodland calling all the time but they are equally at home along tall hedges. In the spring coal tits pair off and they will nest in a hole in a tree or a wall so it would seem that they would readily take to nest boxes. The problem is competition from other small, hole nesting birds and the answer is to put the nest box low down on a conifer which most other birds will leave alone. Unusually they have been found to nest in holes in the ground which must make them very vulnerable to animals such as weasels and stoats. With more and more woodland being planted and with a run of mild winters the coal tit is flourishing. The only possible problem on the horizon is poor weather in the summer with few insects for chicks. An example of this was the summer of 2002 when many insect loving birds had problems coping although there was compensation last year when food was abundant.
