Greenfinches by Edmund Fellowes

The latest Breeding Bird Survey (BBS) report, covering population trends for the UK’s bird species, is released today. This report is a celebration of the dedication of the volunteers who give up their time and take part in bird surveying; collectively they walked 14,996km whilst actively surveying in 2019.

BTO: National Garden Bird Survey Reaches 25 Years

Song Thrush by Edmund Fellowes

In 1995 the British Trust for Ornithology (BTO) launched a weekly garden bird survey: Garden BirdWatch (GBW). Today the project is still going strong, having received over eight million lists of birds and other wildlife from a total of more than 50,000 British gardens, and giving us a unique insight into the changes at our bird feeders over that time.

Information collected by British Trust for Ornithology volunteer bird ringers and nest recorders provides an insight into how some of our resident and migratory birds fared during the 2019 breeding season.

“Our volunteer ringers and nest recorders contribute thousands of hours each year to collecting these invaluable data.

In the latest report looking at the size of our bird populations the Wren tops the list with 11 million pairs across the UK. 

Knowing how many of which species we have is important for many reasons, not least of which is the ability to make better informed decisions when it comes to conservation policy and site management. - Ian Woodward.

Fifty years of citizen science shows a positive response to climate change by a third of English breeding birds.

New research, just published in the journal Bird Study, has shown that one third of 68 breeding species in England have been affected by climate change, leading to notable increases in some and declines in a few.

As part of a project to discover what might be driving the decline in UK Cuckoo numbers, the British Trust for Ornithology (BTO) has fitted four of these iconic birds with satellite tags. These tags will enable BTO researchers to follow the Cuckoos as they make their way to the Congo rainforest, where they winter, and back again next spring.

BTO: Brand new data on gardens keeps growing

Gardenwatch, one of the most ambitious citizen science projects to take place in the UK, was launched during BBC's Springwatch 2019. This collaboration between the British Trust for Ornithology (BTO), BBC, and the Open University leaves no stone unturned to help find out just how important gardens are for wildlife. This is the first time that such information has been collected on this scale.

BTO: Britain's owls need twenty minutes

Tawny Owl (Howard Stockdale)

Evidence suggests that our Tawny Owl population is falling and it might be that we are losing them from our towns and cities. Taking part in the BTO’s Tawny Owl Calling Survey will help make this clearer.

Tawny Owls are very difficult to monitor, as they live their lives during the hours of darkness, so we often hear them rather than see them. We want people to listen for the distinctive ‘hoot’ calls of the males and sharp ‘kee-wick’ of the females. Anyone can take part and the BTO website has a series of Tawny Owl recordings for people to familiarize themselves with the various calls.
