Evolution of female song and duetting in the Chaffinch (Fringilla) species complex

Bailiwick Bat Survey 2022 Report

Acoustic monitoring reveals new records for key species

Inconsistent relationships between area, heterogeneity and plant species richness in temperate farmed landscapes

Declines in invertebrates and birds – could they be linked by climate change?

Are the declines of birds and invertebrates linked by climate change?

Many of the detected effects of climate change on biodiversity have occurred through impacts on food chains.

Reversing declines in farmland birds: how much agri-environment provision is needed at farm and landscapes scales?

How much agri-environment scheme is needed to help birds?

Nest survival of threatened Eurasian Curlew (Numenius arquata) breeding at low densities across a human-modified landscape

​Curlew collaboration to boost breeding success

Research from BTO and the University of East Anglia reveals how land management can support the breeding success of this declining species.

Using satellite data to assess spatial drivers of bird diversity

Development of a prototype early warning system for avian influenza in the EU based on risk-mapping

Proof of concept tool to predict avian influenza outbreaks

Data on the distribution, abundance and movements of wild birds are collected at a national scale within many European countries, thanks largely to the efforts of non-governmental organisations and

The Yellow-browed Warbler (Phylloscopus inornatus) as a model to understand the mechanisms of vagrancy and its potential significance for the evolution of new migratory routes

In addition to their regular movements, birds are also known for their propensity to move beyond their geographic range limits, a phenomenon known as vagrancy, and a behaviour that provides birdwat

Curves for Curlew: Identifying Curlew breeding status from GPS tracking data

Tracking data allows researchers to monitor Curlew without disturbance during the breeding season

The Curlew is of significant conservation concern in the UK, but many questions still remain about their breeding behaviour.

High pathogenicity avian influenza: Targeted active surveillance of wild birds to enable early detection of emerging disease threats

A different approach could provide warning of avian influenza outbreaks

Although we lack complete understanding of the disease links between wild and captive bird populations, the pattern of HPAI emergence in captive poultry reflects the movements of migratory waterfow

Ryevitalise – Bats and Ancient Trees: 2022 Report

Acoustic monitoring sheds new light on North York Moors wildlife

A review to inform the assessment of the risk of collision and displacement in petrels and shearwaters from offshore wind developments in Scotland

Scoping the feasibility of developments to the Terrestrial Bird Indicator for Scotland – urban, farmland and wetland indicators

Birds of Conservation Concern Wales 4: the population status of birds in Wales

What does the latest Birds of Conservation Concern review mean for Welsh birds?

Benefits of protected area networks for breeding bird populations and communities

The numbers of threatened birds are greater on UK sites with the highest levels of protection.

While there is plenty of evidence to demonstrate that protected areas are effective at protecting natural habitats, their benefits for birds and other species have been less well-studied.

Rare and declining bird species benefit most from designating protected areas for conservation in the UK

How protected areas benefit rare and declining birds

Research using data from core BTO surveys shows how protected areas are working for UK birds.

Acute impacts from Teflon harnesses used to fit bio-logging devices to Black-legged Kittiwake Rissa tridactyla

Thoracic harnesses are not suitable for Kittiwake tagging studies.

Biologging devices including GPS and satellite tags, which attach to individual animals and collect information on their movements, are increasingly deployed in ecology and conservation research.

A global biological conservation horizon scan of issues for 2023

Individual, sexual and temporal variation in the winter home range sizes of GPS-tagged Eurasian Curlew Numenius arquata

Curlew are highly faithful to a small winter range, a finding which will inform conservation management for this Red-listed species.

In a collaborative study led by the University of Hull, BTO scientists aimed to find out more by establishing the overwinter home range size (the size of the space used by the birds during winter)
