What are four migrant birds found in UK?

1. Cuckoo: The cuckoo is a well-known migrant bird found in the UK. It is a summer visitor, arriving in April and leaving in September. Cuckoos are brood parasites, meaning they lay their eggs in the nests of other birds, such as meadow pipits and reed warblers.

2. Swallow: Swallows are graceful birds that migrate to the UK in the spring and summer months. They are known for their long, forked tails and their acrobatic flying skills. Swallows build mud nests under eaves of buildings and lay several clutches of eggs during the breeding season.

3. House Martin: House martins are small, dark-coloured birds with white rumps and forked tails. They are closely related to swallows and share similar migratory patterns. House martins build mud nests under the eaves of buildings and lay several clutches of eggs during the breeding season.

4. Sand Martin: Sand martins are small, brown birds with white bellies and rumps. They are the smallest of the three common UK hirundines (swallows, house martins, and sand martins). Sand martins nest in colonies, digging burrows in sandy banks near water.
