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.

Spring migration underway

Huge numbers of Redwings have been heard moving over eastern counties during the hours of darkness over the last week, and summer migrants like Chiffchaffs and Sand Martins are increasing by the day. Check what is happening and what to expect over the coming weeks by following the BTO migration blog.

Who will be first?

With four out of the six satellite tagged Cuckoos we are currently following now in West Africa, it is only a matter of time before one of them heads north on the final leg of the journey back to the UK. At this stage any one of them could move first, follow them as they do.
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.
