Fears for wildlife as migratory birds fly in to UK snowstorm

Second unseasonal cold snap could also harm insect and amphibian populations

The arrival of bitterly cold weather - only a few days before the vernal equinox, the official start of spring in Britain - could have serious consequences for wildlife, experts have warned.

The snow and biting winds, which led to the cancellation of flights and disrupted road travel, will reduce the insect population, creating food shortages for birds and other creatures.
