The wild rock dove is the ancestor to what is probably our most familiar bird - the feral pigeon, which is often found in large numbers in our towns and cities.

Often confused with the larger but similarly shaped lion’s mane jellyfish, the blue jellyfish can be colourless when young and develop a striking blue-purple bell as it matures.

In summer, the sedge warbler can be spotted singing from a reed or willow perch in wetlands across the UK. Males never sing the same song twice, adding new phrases to impress the females.

The rose-red breast, large black cap and thick bill make the bullfinch easy to identify. A plump-looking bird of woodlands, hedgerows and orchards, it also frequents gardens.

Related to the massive albatross, the fulmar is a gull-like bird that nests on rocky cliff edges. Don't get too close, though - it spits a foul-smelling oil at intruders.

The pied flycatcher is a summer visitor, migrating here from West Africa to breed. Look for this small, black-and-white bird in woodland, parks and gardens, mostly in the west of the UK.
