Stover lake frozen
Stover lake in winter

Stover’s autumnal gold’s and red’s, which have been spectacular this year, are finally fading and falling now that winter has descended. The woodland birds will now have fewer daylight hours in which to feed.

Normally many insects have gone into hibernation and are hidden away by the beginning of December. However, this year’s mainly mild autumn, has resulted in many insects still being active. Woods rustle as blackbirds and thrushes sift through the leaf-litter in search of food. Male robins are singing at the moment to mark out their territories and most will have paired up by Christmas. In early winter, both males and females are highly territorial. Song thrushes should start to sing in December, joining the wrens and the dunnocks. Keep an ear out for the mistle thrush’s song – normally they start singing after Christmas but have been heard singing most days since 14th November. Crossbills will now be nest building – the hatching of the chicks coincides with the opening of conifer and alder cones which peaks in February. These will attract other seed-eating birds such as siskin and redpoll. If the scales on the conifer cones have been split longitudinally, then crossbills have been feeding on them. They are easily approachable at this time of year when they are concentrating on feeding. There are plenty of other birds to see in the Park in the winter which include great spotted and green woodpecker, bullfinch, siskin and redpoll. Chaffinch, redwing and blackbird can be seen coming into Stover at dusk to roost in some of the rhododendron bushes. The best time to view these birds during December is from 3.30pm onwards; different birds arrive in groups of 30 to 50 and then assemble together. It’s often not until after Christmas that fieldfares are seen inland in significant numbers, however 8 were seen flying over the Park on 18th October. If you are really lucky you may spot a woodcock resting on the ground – however its camouflage makes it tricky to see. Tawny owls are at present pairing up and establishing territories so are at their most vocal. Wood pigeon flocks have been seen flying over the Stover area – some will consist of migrating European birds.

A tufted duckOn the lake pochard numbers peaked at 4 along with 8 tufted ducks during last month. A male and female Mandarin duck were present on the lake during the first half of last month. A very late brood of mallard ducklings hatched on 2nd November due to the mild weather. Unfortunately they didn’t survive due to the Herring Gulls. There are more gulls around at this time of year on the lake than in the Spring when they fly to the coast to breed. Two great crested grebes were present on the lake up until 13th November. A male and two female wigeon were seen on 9th November, with 4 teal the day before. Wigeon are unusual as they are grazing ducks, eating grass like geese, but will also ‘upend’ whilst feeding on the water. Male wigeon have a striking yellow forehead whereas female wigeon are more uniformly brown than other female

ducks, with a small bill. Teal are Britain’s smallest duck and their population is increased by a large migrant population from northern Europe in winter. Two goosander were recorded on 18th November.

Goosander are a type of sawbill duck having a serrated cutting edge to their beak that enable them to feed on fish, and are frequently seen on reservoirs and lakes during winter. Up to 4 cormorants were recorded during November. Their numbers are building at this time of year and can be seen perched in the trees on the island. The peak count for black-headed gulls during November was 100. Herring gulls were seen throughout last month. Water rail are present in the marsh along with over 100 snipe. The snipe are easiest to see when they are standing on the edge of the marsh. Many more rest up in the middle making them impossible to spot. At dusk they can be heard leaving the marsh for their feeding sites on nearby pasture. Kingfishers and herons have been recorded throughout November.

 

Mammals are easier to spot now that the ground cover has died back and they spend more time foraging. Foxes appear particularly striking as their breeding season gets under way, peaking early in January. Foxes become increasingly active at this time of year and can often be seen in daylight hours. Even if you don’t see them, you will most certainly hear their barks and screams at night. Their distinctive musky smell is obvious all over the Park.

Some insects can be seen over the winter months such as a small brown moth known as the winter moth. Oak and sitka spruce are favourite hosts, of which Stover has plenty ! Common darter dragonflies were seen on 11th and 15th November. Any warm sunny days during the winter months may rouse brimstone, red admiral and peacock butterflies from their hibernation so they may be seen briefly on the wing.

Next years buds are starting to appear on many of Stover’s trees. The scarlet elf-cup fungus is out at the moment and can be found on rotten wood in the damper areas of Stover’s woodlands.

There are a few tickets left for the Christmas Carols on the 13th – contact the rangers for more details.

Merry Christmas !
