Although breeding is influenced by changes in the weather from year to year, most birds breed between the beginning of March and the middle of July. Any disturbance which forces the bird to leave its nest, even for a short period, may lead to loss of the brood as the eggs or young chill and die very quickly or may be taken by predators. YOU can help by:- Keeping to paths and tracks during the breeding season. Keeping your dog on a lead (lambing takes place at about the same time). Avoiding young birds, aprticularly on the ground, or distresses parent birds; walk around the area and move away quickly to allow the parents to return. Avoiding activities in large groups during the breeding season. Spreading the message to others so that they can help as well.
