Habitat forms a natural way of classifying wildlife populations, such as woodland birds, but determining how many of which species might be found in a habitat patch and how numbers change over time is complex. Field surveys, analyses of scheme data and targeted experiments by BTO have investigated habitat composition effects, such as of woodland structure, farmland heterogeneity, connectivity among freshwaters and heathland vegetation, on bird abundance, movements, breeding success and survival.
Urban and coastal breeding lesser black-backed gulls (Larus fuscus) segregate by foraging habitat
A tale of two warblers
Breeding Bird Survey (BBS) results show very different population trends for Willow Warbler and Chiffchaff - but what is driving this difference? BTO research reveals climate is key.

GPS tracking reveals landfill closures induce higher foraging effort and habitat switching in gulls
During the 20th century, gull populations across the globe increased rapidly in response to human activities, with the availability of waste food in landfill sites a key driver of their success....
Herring Gulls aren't after your chips
New BTO research using GPS tracking reveals that declining Herring Gulls are more likely to be foraging on Mussels than pilfering chips.
Sensitivities to land use change by breeding Short-eared Owl (Asio flammeus) in Britain
Populations of Short-eared Owls are declining across many parts of their range, including here in Britain, where their breeding range contracted between 1990 and 2010. The relationships between a...
