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 disturb any nesting bird. It is also 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.
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.
