The breeding season starts early for Scottish crossbills. As with many of the creatures that have a close link to Scotland’s native pinewoods, one of the best ways to help Scottish crossbills is to make sure that their favourite habitat is in good shape. 605079649. On winter and spring mornings you might see small flocks of crossbills clustering around ripening cones, or you could come across the discarded cones on the forest floor. More than 140 sites are so important for birds they hold international designations. First conceived for a visitor centre in Glenmore, the tartan was then used as a logo for the Forest of Spey and woven into scarves for the Cairngorms Partnership – the forerunner of the Cairngorms National Park Authority. The seeds of conifers, from both Scots pine and non-native trees, support Scottish crossbills all year round. Scotland's seas are among the most biologically productive in the world; it is estimated that the total number of Scottish marine species exceeds 40,000. In autumn, birds often come together in small flocks as they roam the forests in search of suitable cones. And like many other members of the finch family, Scottish crossbills – especially the males – are brightly coloured. Families may split up at this point, with the father feeding some of the young and the mother feeding others. Although it is considered threatened at present, the future looks brighter for the Scottish crossbill, as all the work currently underway to restore the native pinewoods of Scotland will provide the habitat for an expansion of its population in years to come. The Scottish crossbill is endemic to Scotland, and is the only bird which is restricted exclusively to the UK. The crossbill feeds on pine seeds either by pulling a cone off a branch and then holding it with its feet while it uses its bill to extract the seeds, or it acrobatically moves around the cone, extracting the seeds without removing the cone from the branch. Thin stripes of orange-red and yellow show male and female crossbills in the trees. Two other crossbill species occur in Scotland: the widely-distributed common crossbill, and the much rarer parrot crossbill, which is restricted to Strathspey and Deeside. There are a few records south of these areas, but, at the moment, they seem to be absent from the west Highlands. When crossbills are nesting, they will often favour particular pines near their nest which are heavily-laden with cones and will return to them repeatedly to feed. The Darwin Mounds are an important area of … Parasites of the crossbill include a louse (Philopterus curvirostrae), a tape worm (Anonchotaenia globata) and a fluke (Brachylaemus mesostoma). We look forward to welcoming you safely to our forests and land. Before the native pinewoods were reduced to their present figure of just 1% of their original extent, the Scottish crossbill must have been much more numerous and widespread, with a population between 10 and 100 times that of today. Nest predation is, however, quite common, with carrion crows (Corvus corone corone), hooded crows (Corvus cornix) and red squirrels all preying on both the eggs and young birds.

That makes identifying them all the more difficult, because these are also places that are popular with common crossbills. Osprey, snow bunting, dotterel, great skua, Scottish crossbill, crested tit and several others are just some of the species especially associated with Scotland. The next steps in the Scottish Crossbill study are to establish the bird's population size and habitat requirements. All crossbills are instantly recognisable by the curved mandibles which cross over when their bills are closed – they are the only type of bird which exhibits this characteristic. Courtship amongst crossbills begins in late winter or early spring when the males in a flock sing loudly and in chorus, with each individual seeking to broadcast his fitness for mating. You probably won't know if you've seen a Scottish crossbill unless you are very expert at identification or can record their calls – all three species look alike and a sonogram is the only reliable way to tell them apart.
