Cuckoo events are a type of event that occurs when a cuckoo bird lays its eggs in the nest of another bird, typically a reed warbler or a dunnock. This type of event is also known as brood parasitism.
The cuckoo bird will often remove the eggs or young of the host bird from the nest, and then lay its own eggs in their place. This allows the cuckoo bird to raise its young without having to build its own nest or provide food for its young.
Cuckoo events are an example of a type of evolutionary strategy known as "brood parasitism," where one species takes advantage of another species' parental care to raise its own young.
