British wildlife in February | BBC Wildlife Magazine
Info seputar Togel Singapore 2020 – 2021.
There’s a frost on the ground and the trees are still bare, but nature’s hinting that spring isn’t too far away.
If you are planning to see wildlife, please follow the latest government advice regarding coronavirus, and bear in mind that there are different restrictions in place between England, Wales, Scotland and Northern Ireland, and in more localised areas as well.
Rook (Corvus frugilegus)
Long before winter is out, new life stirs in still-bare treetops. Come February, mistle thrushes are whistling their mournful, far-carrying song over and over from the loftiest twigs, great spotted woodpeckers are drumming on resonant dead wood to announce their territory and, safe in their dreys, female grey squirrels are nursing their first young of the year.
Rooks, too, begin breeding remarkably early. Their rookeries in the crowns of tall oak and ash (once, elm was the tree of choice) are already a hive of activity in February, as established pairs bring sticks to patch up their tatty nests or try to pinch them from neighbours. Rooks mate for life – rare among British birds, but the norm among our corvids – and devoted partners will sit beside their nest to groom one another affectionately. Known for their social intelligence, they are able to recognise individual birds in their colony.
We can’t manage that, but it is possible to tell rooks from carrion crows, even at long range, by the former’s freer wing beats and longer ‘fingers’ at the wingtips. On the ground, identification becomes much easier – a rook looks rather tousled, with a rakish forehead and feathering on the legs that gives the impression of baggy shorts. The bare grey skin around the pointed bill is also unmistakable.

Alexanders (Smyrnium olusatrum)
The exuberance of spring may be weeks away, but road verges and path sides are starting to green up. Look for jagged nettle shoots, spears of emerging bluebells and heart-shaped leaves of lesser celandine. Another well-advanced plant this month is Alexanders, a relative of cow parsley brought here by the Romans, which flourishes by the coast in Ireland and southern Britain.
Its glossy leaves are grouped in threes and, like the juicy stems, sought after by foragers. Yellow-green flowers (pictured) appear from April, though you might notice some in bud already.
Roe deer (Capreolus capreolus)
Unlike their red and fallow cousins, roe deer do not gather in large herds. They are usually seen alone or, particularly at this time year, in small groups of up to half a dozen or so. You’ll often see them feeding in the open at the edges of fields and woods in the low light of early morning and evening.
With Britain’s roe population at a record high – probably more than 250,000 strong and still increasing – the odds are that any train or motorway journey should reveal a few. In February and March, they are still in grey winter coats and bucks are busy regrowing antlers.
The roe deer’s scientific name, Capreolus capreolus, is an example of a tautonym, where the genus and specific name are the same.
Barns owls appear to float through the air as they quarter rough grassland in search of voles. They fly in a sweet spot, roughly 2–3m above the ground, folding their long wings to drop like a stone the instant they hear the rustle of prey.
Barn owl survival is closely tied to vole numbers and the weather – freezing conditions and flooding make hunting difficult. February 2020 was Britain’s rainiest on record, and there is growing concern that any shift towards wetter winters, coming on top of other pressures, could have a severe impact on these quicksilver birds.
Nuthatch (Sitta europaea)
This boisterous bird is a delight at garden birdfeeders, and comes second only to the house sparrow and greenfinch in the pecking order. While sunflower hearts can be swallowed in one, the nuthatch’s signature winter feeding technique is to wedge acorns and hazelnuts into cracks in tree bark before hammering them to pieces, hence the species’ old names of ‘nut hack’ and ‘nut jobber’. With such heavy use, its bill becomes shorter as the season progresses. Formerly absent from Scotland, the nuthatch has recently colonised the southern half of the country.

Elder (Sambucus nigra)
All winter deciduous trees are covered in buds, just biding their time, and (with practice) you can use them to tell species apart. One of the first to burst into leaf is the elder, a common shrub-like tree of hedgerows and scrubby woodland. Its reddish-purple buds, which sit in pairs on opposite sides of the twig, split to reveal ferny leaves with saw-toothed edges. Elder bud burst is one of many seasonal events recorded every year by participants in the Woodland Trust’s long-running Nature’s Calendar project.

Amphibians such as the common frog rely on temperature as the cue to wake up from hibernation and start breeding. Warm spells can thus result in frogspawn as early as Christmas, and this has always been the case – though, with milder winters, such instances are on the rise.
Early frogspawn is most likely in south-west England, from where sightings rapidly spread east and north throughout February and March. A 2009 study found that for every 1°C rise in temperature, the average spawning date moves forwards by 5.1 days. Spot spawn in the sunniest part of the pond.

Stock dove (Columba oenas)
When was the last occasion you spent any time watching pigeons? The stock dove is one of those species that hides in plain sight, largely because we so often mistake it for its larger and more familiar relative, the woodpigeon. However, if you pause awhile to scan pigeon flocks in winter fields, you should discover that it is rather more common than you thought. The stock dove is a prettier, neater-looking bird, with two black wing bars and button-like black eyes that give it an ‘innocent’ appearance.
Small tortoiseshell butterfly (Aglais urticae)
Small tortoiseshells have evolved to hibernate in cool, dry places with a stable climate, so unheated rooms and shed are perfect. Like overwintering red admiral and peacock butterflies, they’re liable to be disturbed by any of us moving aorund, radiators coming on, or midwinter sunshine through a window. It can be upsetting to see them flutter helplessly, but gently catch and re-locate them and they will cool down again. Every small tortoiseshell is precious, since the species’ population declined by 78% between 1976 and 2018, though last summer was their best since 2014.

Wood mouse (Apodemus sylvaticus)
Wood mice remain active all winter, relying in part on caches of food laid down in autumn. Don’t be fooled by the name. Apart from on a few Scottish islands and mountains, you can encounter these endearing nocturnal rodents, also known as field mice, just about anywhere. They’re more than happy to share our homes, so just because the mouse is indoors, that does not make it a house mouse. The best way to tell the species apart is by the ears, which are much larger than wood mice.

Hazel catkins (Corylus avellana)
Hazel catkins were once known as lamb’s tails. partly for the obvious resemblance but also perhaps because both are welcome signs of the coming spring. Dangling from bare twigs, these pendulous flowers spikes-botanists would call them inflorescences-are covered in hard, golden scales and are entirely male. They are among the first flowers of the year to appear on any native British tree. Hazel also produces female flowers, but you need to hunt for them as they’re minuscule by comparison-tiny red tufts strangely reminiscent of sea anemones.

Little auk (Alle alle)
When people meet their first puffin, they often comment how much smaller it is than expected. The little auk is a third smaller still. This plankton eating seabird does not normally visit British or Irish waters, as it’s a creature fo the High Arctic, breeding on vast cliffs in places such as Svalbard, sometimes in colonies a millions strong. During winter gales, exhausted birds end up ‘wrecked’ far to the south. After the worst storms, hundreds of these very tame, starling-sized auks may be seen close inshore, mainly in Scotland and along England’s east coast.
The little auk’s scientific name, Alle alle, is an example of a tautonym, where the genus and specific name are the same.
Mallard (Anas platyrhynchos)
This month, park-lanes ad other wetlands can feel like cheesy discos, full of head-flicking, rump-waggling, whistling, cooing and bling. Male ducks are in prime condition and busy courting. Drake mallards display in groups, frequently pumping their heads up and down, or rising up out of the water. There’s a lot of splashing and energetic chases, as rival jostle to be the one swimming beside a female. Mallards are thriving in the UK: a major new report on our bird populations shows that breeding numbers have almost trebled since 1970.
