First gannet chicks spotted on Bass Rock
The first gannet chicks of the breeding season have been spotted on Bass Rock off the east coast of Scotland.
Birdwatchers have been keeping a keen eye on the rock, which lies in the Firth of Forth, and is the largest single island gannet colony in the world.
The outcrop has entered a key period in the breeding season and will be home to about 150,000 gannets by July.
The area is of international importance and in total serves as habitat for in the region of 500,000 seabirds.
These include puffins, kittiwakes, guillemots, razorbills, fulmars, shags and terns.
Gannets are Britain's largest seabird, with a wing span of more than 6ft, and can live for more than 30 years.
They have such good eyesight that they can spot schools of fish below the surface of the water and dive at speeds of up to 62mph.
Bass Rock was formed 320 million years ago and is the remains of one of many active volcanoes in the area.
It has been uninhabited since 1988 when the last lighthouse keeper departed, leaving it to the birds.
