Part fourteen mammals of the mountain sides.

Britain`s mountains are not very high-only one, Ben Nevis is, above 4,000 ft (1,200m)- but they are bleak places for warm blooded creatures to live, especially in winter. For roughly every 500ft (150m) of height above sea level, it gets almost two degrees colder. Rain and mist as well as stronger winds also add to the chill. Trees rarely grow on high, windswept uplands, so there is little shelter. Consequently, few mammals live on the exposed high ground. Although they forage on the heights in summer, red deer and, to a lesser degree, mountain hares move to lower ground for the winter. Small mammals, such as field voles that live amid the upland grass, do not make long migrations. Although they lose a lot of body heat because they have a large surface area of skin in relation to their bulk, they can find shelter in burrows or among thickets of heather or bilberry. Despite the cold, small spiders and insects are surprisingly numerous amid upland vegetation, and provide food for pygmy shrews. Stoats thrive on field voles but will also take meadow pipits and other upland birds. Crows and foxes search the mountain- sides for carrion such as dead hares and sheep. Small herds of feral goats may be seen in a few mountainous areas. They vary widely in colour, ranging from white to piebald, skewbald, dark brown or black. Young goats are not likely to be seen before April. In their winter pelage, mountain hares look like snow against the dark heather. They show up only when they move. On upland slopes they take the place of rabbits and brown hares. Many upland areas now have commercial plantations of dense conifers(some wildlife trusts are now taking some of these out). They rob mountain hares of their living space, but may provide homes for pine martins. Red deer move down the valley during winter, returning in spring. Stoats have great camouflage in winter because of their winter pelage. It also helps to preserve body heat, because white fur radiates less than dark fur. Where there are meadow pipits there may also be pygmy shrews. Both feed on tiny insects among the stones and heather. Pygmy shrews remain well hidden but nay be heard squeaking.

things to look out for in april.

Swallows nesting in spring.

The beautiful spring mornings are finally here for us all to see,Ive just got back from a weeks holiday in north wales and there was not a drop of rain in sight.Bluebells,ramsons and hawthorn blossom are sights that we should now be able to see during April as the climate starts to get warmer.Bluebells and ramsons will carpet the woodland floor,While the hawthorn blossom should lighten up many a hedgerow in Worcestershire.You should be able to see the first house martins and swallows as they return from their epic trip to south Africa.Badger cubs make their first appearance above ground during April,Dusk is a really good time to go and watch them.Its also a good time to look out for wood mice rustling in the leaf litter as you walk through the wood.The sound of the cuckoo is the day i say spring has arrived,The cuckoo is a migrant from Africa and will use meadow pipits,reed warblers and dunnocks nest for themselves to lay their eggs.When the cuckoo chick hatches it instinctively pushed the other chick or egg out of the nest,So the adoptive parents tend purely for the cuckoo chick.Blackbirds,starlings and song thrushes are also really busy this month.Also look out for the Ariel displays of skylarks and meadow pipits.Orange tip butterfly's start to emerge during April around plants from the crucifer family in particular the Lady's smock,Laying their eggs on the leaves of the plant,They then feed as caterpillars on the mustard oils of their food plants.Its a good time of year to see grass snakes,adders and slow warms basking in the spring sunshine. Newts start mating from now as well so look in the shallows of your pond or someone elses and you may see them.The male woos the female with his tail flicking performance,and his bold marking on his body. You probably wont see the female laying her eggs, She wraps a living leaf around each one of her eggs,The leaves will then be bent over with a single egg inside.Start to look out for vixens with her fox cubs as well
