What Kind Of Bird Eggs Are These

Before we go any further, I need to let you know that disturbing these nests and or eggs is considered a violation and against the law. Taking eggs (except for some ‘pest’ species) is illegal under the Wildlife and Countryside Act 1981 – and rightly so.

However, you don’t need to break the law to be an egg-detective at this time of year – the signs are all around us. What are those fragments of speckled eggs on the garden path? Who laid that bright blue egg dumped on the lawn? Remember, eggshells don’t just fall out of a nest. Predators such as foxes or magpies may carry them away, as do parent birds, often to help conceal the location of vulnerable babies.

Now that is out of the way, let the egg-detecting commence. The following references 12 nests and the eggs contained inside to use for identifying what kind of bird has decided to make their home in the garden or on the porch of your home.
