Nature Notes

On the heath and bog, reptiles now retreat to their underground Winter homes called hibernacula. The occasional mild and sunny day may allow for some activity.

Also making use of any warmer days are some of the butterflies. Many species overwinter as eggs, laid on the caterpillar food plants. A few such as the Red Admiral and Tortoiseshell can overwinter as adults and will often shelter hidden in garden sheds or garages. Before hibernating, they build up their food reserves and can be seen feeding on late flowering plants such as Ivy. If you have Ivy on trees in your garden think twice before removing it. Contrary to popular belief it is not a parasite and does not "strangle" trees. For birds and insects it provides all year round shelter, a late nectar source and berries as food. Nesting birds and even bats have been known to use it as a home.

Out on the bog you may be lucky enough to glimpse a Snipe. This is a well camouflaged wading bird that spends most of its time feeding on wet ground. Usually only noticed when disturbed, look for the extra long bill as an identifying feature. Also look out for incoming migrants such as Fieldfare, Redwing, Brambling, Redpole and Siskin.

The occasional dragonfly may still be seen along the boardwalk, usually resting on the boards or rails, trying to absorb the little warmth they can from the weak sunshine. These insects rely for food on new larvae emerging from the bog pools each year. The few adults you now see will gradually die over the coming weeks.
