With the shortest day thankfully behind us, spring isn’t far away. Spring is signalled in the form of birdsong. The usual communication calls of birds are joined by the songs of territorial birds claiming their space and advertising for mates. Apart from robins, bird song is usually delayed until late-December or even until the New Year. For months the sound of robins defending their territories has been the only true song we have heard. Great tits joined in during the last week of December, with the first mistle thrush on 17th. Listen out for blackbird and song thrush song over the next few weeks. The first song thrush was heard singing on 28th December. The starlings, chaffinches and greenfinches that will join the chorus later are still gathered in flocks – there is still the rest of the winter to get through before nesting! Listen out for great-spotted woodpeckers drumming on the trees – if the weather remains mild it’s possible to hear them in January. One was very advanced being heard on 13th December.
Keep an eye out for wrens, which will often crowd together to roost in favoured sites in large numbers to conserve heat. Nestboxes are often used – more than 50 birds have been found in a single box at night. Listen out for the hoots of tawny owls. Like robins they have already paired up and have set up their territories. The crossbill, a coniferous woodland finch, is now nesting making it the earliest nesting British bird. Nests are situated high up in pine trees and can be very difficult to spot. Eggs are laid at this time of year because the crossbills’ main food, pine cone seeds, become available for the first time in the depths of winter. If cone crops are good, crossbills can easily gather enough to feed themselves and their nestlings. Most of the early nestlings fledge this month. Another bird found in the conifer plantations and has been heard singing during December is the goldcrest – Europe’s smallest bird. Our resident population is boosted in winter by immigrants arriving from colder conditions in the north. A firecrest was spotted in amongst a flock of goldcrest on 28th December. Firecrests look very similar but are identifiable by their black and white eye stripe. They are chiefly a passage migrant seen in autumn and winter. Over 100 siskin were recorded over Christmas in the alders around the lake.
There are small finch and redwing roosts in the Park – the latter are the smaller of the two winter-visiting thrushes that stream in from Europe. They feed on invertebrates for as long as they can, but when the ground freezes they transfer to fruit. They flock to berries, hips, haws and windfalls. Because they are so conservative in their tastes redwings often starve to death while other thrushes are seen tucking into kitchen scraps, fat and seeds.
Keep an eye open for woodcock this month. They lie low in damp woods, not taking off until you almost walk on top of them. They are more evident at the moment, their numbers swelled by visiting birds from the frozen North and Scandinavia.
One great-crested grebe was recorded on the lake during the first half of last month. Up to 4 cormorants have been present during December. Highest counts of wildfowl were 6 pochard along with 4 tufted duck. A male scaup was spotted on 3rd December. Similar to the male tufted duck, it can be identified by its grey back and lack of crest. Up to two pairs of mandarin duck were spotted during the latter half of the month. Up to 27 goosander have been seen on the lake. Along with the red-breasted merganser it is a sawbill duck which feeds on fish (hence needs the serrated cutting edges to its bill ie. ‘sawbill’) and are frequently seen on reservoirs and lakes in the winter in large concentrations. Small numbers of herring and lesser black-backed gull were also present on the lake last month. Kingfishers are easier to see at this time of year. With no leaves on the trees, the contrast of their bright feathers against the muted colours of winter makes them stand out brilliantly. Herons breed earlier than most birds, and once it turns mild then look out for a lot of noisy activity at the heronries. Water rail have been heard calling from the marsh and 96 snipe were recorded on 8th December.
On the mammal front, now is a good time to see roe deer, foxes and stoats as they search for food. The foxes and squirrels breeding season is currently underway. Listen out for foxes mating calls during the night; the most eerie is the vixen’s scream announcing that she is ready to mate. During mild winters amphibians such as frogs and toads have started to spawn this month. Two brimstone butterflies were recorded on 22nd December, along with a red admiral on the 18th. Sightings are now less likely with the forecast of colder weather.
Snowdrops are due to emerge in January and the honeysuckle leaves have already started to grow. Keep an eye out for hazel catkins and primroses which will start to appear during January. There are a few ferns, such as the hard fern, which survive the winter, giving some greenery to Stover. Most of the fungi have now died down, but one of the stranger species, known as the earthstar fungus, appears at this time of year. It can be found in deep leaf litter and on old twigs under trees. At first, they are more or less buried, but eventually their globular fruiting bodies appear from the surface and split open into pointed segments. These curl back giving the fungus its name. Barometer earth star fungi were discovered in the Park six years ago and have appeared again last month. Only 14 records exist for Devon, the majority of which are from the 1800’s making this species very rare indeed.
The Carols with the Newton Abbot Salvation Army Band in December was very well attended again.
