The most notable changes over the past 75 years have been an increase in temperature and a loss of roughly 90% of lowland meadow and pasture, mainly converted to arable farmland and improved grassl
Flight heights obtained from GPS versus altimeters influence estimates of collision risk with offshore wind turbines in Lesser Black-backed Gulls Larus fuscus
As previous BTO research has shown, bird-borne tracking devices are essential for shedding light on seabird flight behaviour.
How do offshore wind farms affect seabird behaviour?
Research reveals a crucial link between wind farm design and Sandwich Tern behaviour in the North Sea.
Combining remote sensing and tracking data to quantify species’ cumulative exposure to anthropogenic change
The results showed that although the actual amount of change had been greatest on the breeding grounds, cumulative exposure to changes in direct mortality risk and climate were highest during the C
The current state of nature
The UK, like most other countries worldwide, has experienced a significant loss of biodiversity.
This issue contains articles on Redshank and Dunnock nest finding as well as a feature with advice and guidance on accessing funding to help fund fieldwork.
A demonstration of the value of recapture data for informing moult phenology models for species with imperfect moult data.
Developing statistical approaches to better understand feather moult
Researchers seeking to understand moult in the context of these other events need robust measures of moult duration and timing.
The UK Turtle Dove population is thought to have peaked around 1970, when there were an estimated 125,000 pairs.
To implement effective conservation actions, locally and globally, we need to quantify the importance of the multiple, often interacting, threats to seabird population growth rates.
Analysis of wintering waterbird population trends for the Lough Neagh and Lough Beg Special Protection Area (SPA)
Waterbird trends for the Lough Neagh and Lough Beg Special Protection Area
This analysis of Wetland Bird Survey (WeBS) data for the Lough Neagh and Lough Beg SPA provides details of wintering waterfowl population changes around the loughs and assists in identifying potential
Lasso Penalisation identifies consistent trends over time in landscape and climate factors influencing the wintering distribution of the Eurasian Curlew (Numenius arquata)
Detecting Brown Rats on seabird islands
Introduced Brown Rats can devastate seabird colonies, predating both eggs and chicks. Can we use bioacoustic technology to detect and monitor this threat?
Local colonisations and extinctions of European birds are poorly explained by changes in climate suitability
Assessing movements of Lesser Black-backed Gulls using GPS tracking devices in relation to the Galloper Wind Farm<br />
Disproportionately high risk for threatened seabirds from marine plastic.
Seeing the wood for the trees, irregular silviculture supports bat populations in conifer plantations
How do bats respond to different approaches to the management of conifer plantations
Conifer woodland covers 1.6 million hectares of the UK and is an important source of economic revenue.
Spring arrival of the Common Cuckoo at breeding grounds is strongly determined by environmental conditions in tropical Africa
West African stopover determines timing of Cuckoo arrival
The authors use 11 years of satellite tracking data from 87 male Cuckoos, tagged at 11 sites across the UK, to examine variation in migratory timing throughout the annual cycle and its potential co
Does the timing of Blue Tit breeding vary with woodland composition?
Changes in breeding wader populations of the Uist machair and adjacent habitats between 1983 and 2022
Study shows 25% decline in breeding waders between 1983 and 2022
Raptor ID training (2 sessions, Wednesdays 7pm)
The training will consist of two weekly online modules of 90–100 minutes each, complemented by supported self-study exercises which will be provided after each session. The training will be run by BTO staff members Nick...
