How birdwatchers can tell us about declining mammals

The UK’s mammals present particular challenges for monitoring; they live in a wide variety of habitats, vary enormously in size and can be very difficult to see, but as this paper shows, Britain’s army of volunteer bird surveyors could come to the rescue.

Can volunteers’ data be used to monitor land cover change?

A new study shows that Breeding Bird Survey data can help with habitat monitoring.

Cuckoos: England’s loss is Scotland’s gain

The Cuckoo is quickly declining from the English countryside, but this new study using BTO data shows that despite its decline in the south of the UK, it is increasing in the Scottish Highlands, the population is increasing.
Woodcock - Graham Giddens

Understanding the influence of habitat upon breeding Woodcock numbers in Britain

Woodcock are in long-term decline. Due to incomplete knowledge of their habitat requirements, there is uncertainty as to what causes these declines. A BTO/GWCT survey investigates Woodcock habitat associations. 
Nightingale - John Spaull

Counting songs: estimating the UK’s Nightingale population

A new study led by BTO estimates the UK Nightingale population at 5095 – 5983 territorial males. The study also highlights the importance of Lodge Hill SSSI as important sites and discusses the use of appropriate methodology when estimating populations for scarcer species.
