Emerald Demselfly The Wildlife Year in the Cam Valley

'The Wildlife Year' is a month by month guide to the things that may be happening in the Cam Valley Wildlife Group area.

This is only intended to be a guide and it is neither complete nor entirely accurate - timings can vary because of a number of factors, principally weather conditions.

If you think of anything to add or think something needs correcting please let us know.

January

A relatively quiet month but snowfalls can give clues to animal (particularly mammal) activity through tracks left.

Flora

  • Hazel catkins appear.
  • Snowdrops come into flower.
  • Various species may be found in flower (e.g. Groundsel and Speedwells).

Birds

  • Early singing birds can be heard including Blue Tit, Great Tit, Robin, Nuthatch and Starlings.
