British Birds’ Eggs

British birds’ eggs are found in a variety of shapes, sizes and colours. Although the default colour of a bird’s egg is white due to the calcium carbonate from which the shell is made, other pigments can cause eggs to take on different colours and patterns.

Passerines tend to lay coloured eggs: birds that build their nests in trees are more likely to have blue or green eggs while those who build their nests near the ground usually produce brown or speckled eggs to help with camouflage.

Remember in the UK wild birds are protected by law under the Wildlife and Countryside Act 1981 and it is  illegal to intentionally take or destroy the eggs of any wild bird or have in one’s possession an egg that has been taken in contravention of the Act. It is also illegal to intentionally or recklessly disturb any nesting bird listed on Schedule 1.

If you have knowledge of the whereabouts of any birds’ nests, particularly rarer breeds, then please be careful with that information. Do not openly discuss or post any information online that could be used by egg thieves even when the breeding season is over.

  1. Have located in rural Cheshire some 3 egg shells presumably predated from a nest brown grey pullet egg size but more grey than chicken eggs. Any idea what they might be? We also have a mistle thrush nest on 3rd clutch. The 1st set of juveniles seemed to join in with air support against jackdaws when 2nd set left nest. Is this normal?

  2. Found a nest on the ground in my garden with 5 eggs in it. They are about the size of pegeon eggs but brown speckled. Can’t identify them. Any ideas? Eggs measure 37 x29 mm.
