Star species: common cranes, kingfishers, avocets, oystercatchers
Sand martins and swallows arrive in early spring. Mediterranean gulls have become regular spring migrants and common cranes will display and begin nesting.
The last of the white-fronted geese will leave the reserve around April and cuckoos will begin to arrive - listen out for their distinctive call.
Towards the end of May kingfishers may hatch, depending on their incubating time - look out for them from the Kingfisher Hide. Warblers including blackcap, sedge warbler and reed warbler will begin to breed.
Spring is a great time to spend time down at our Kingfisher Hide to see if you can spot any kingfisher activity.Watch online
Out of hours and when you can't get to the reserve, you can still get a daily dose of Slimbridge with our webcam.
