The Cuckoos are coming

The first of our tagged Cuckoos is well on his way and has crossed the Sahara, the Mediterranean and Spain. Selborne is on the southern edge of the Pyrenees but will he be the first back to the UK? Follow them as their journeys unfold.

Find the Gap

BTO has just launched a new web-based tool for filling the gaps on the map for the new European Breeding Bird Atlas (EBBA2), the most ambitious continental scale atlas of breeding birds ever produced. Learn how to help Find the Gap.

Help with bird ID

This is one of the best times of the year to develop your bird identification skills. Only the earliest summer migrants are here so you have the opportunity to perfect your skills in identifying these before the other species arrive to confuse things. Get to grips with Chiffchafff quickly before the Willow Warblers arrive and perfect your Sand Martin ID before the House Martins and Swallows pour in. Check out our full range of free bird identification videos designed to help you develop your birdwatching skills this year. 
Walk for wildlife

Get walking for wildlife

This year we are part of Walk 4 Wildlife, a series of events to enable people to help protect our planet's amazing wildlife. On 19 May, thousands of primary school children will be taking part in an attempt to break a Guinness™ World Record which currently stands at 231,635 people all walking at the same time! Why not get your school to organise their own sponsored walk for BTO's work looking out for birds? In addition, there are five very different sponsored walks across the country throughout the summer.
