Hedgerows form an important semi-natural habitat for birds and other wildlife in English farmland landscapes, in addition to providing other benefits to farming. Hedgerows are currently maintained through annual or multi-annual cutting cycles, the timing of which could have consequences for hedgerow-breeding birds. The aim of this report is to assess the impacts on nesting birds should the duration of the management period be changed, by quantifying the length of the current breeding season for 15 species of songbird likely to nest in farmland hedges. These species are Blackbird, Blackcap, Bullfinch, Chaffinch, Dunnock, Garden Warbler, Goldfinch, Greenfinch, Linnet, Long-tailed Tit, Robin, Song Thrush, Whitethroat, Wren and Yellowhammer.

This report presents the main findings from survey work delivered using passive acoustic monitoring devices deployed across the Bailiwick of Guernsey.

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 research questions to be pursued.

Static acoustic bat detectors were deployed over a six-month winter survey season, to explore the possibility for using acoustics to detect and monitor the presence of Brown Rats on Rathlin Island in Northern Ireland. This report provides an overview of the survey coverage and main results from 2022/23. This research used the BTO Acoustic Pipeline to process and analyse sound recordings.

A programme of Lesser Black-backed Gull Larus fuscus tagging and tracking work was initiated within the Alde-Ore Estuary Special Protection Area during the 2019 breeding season, and continued throughout the 2020 breeding season, in order to fulfil requirements of the Galloper Wind Farm Ornithological Monitoring Programme and test key predictions of the Environmental Statement. The results from both the 2019 and 2020 breeding seasons of tracking are summarised within this report.
