Angus Croudace

With a broad interest in the Scottish landscape, Angus studied earth sciences and concluded his degree with a peer reviewed publication researching plumage colouration in dinosaurs. After switching his focus to ecology in 2020 Angus joined Redwing in 2023 and has built a reputation as an accomplished fieldworker and project manager. Whilst experienced in butterfly, habitat and peatland surveys, Angus specialises in focused ornithological monitoring, particularly in the upland environment. Fortunate enough to have shadowed or been mentored by some of the Scotland's leading ornithologists, Angus has an extremely detailed understanding of hen harrier and wood sandpiper ecology. Outwith the core breeding season, he has spent a lot of time surveying for eagle, hen harrier and red kite roost sites. He contributes data from his own personal monitoring to the Highland Raptor Study Group and is involved in several ongoing Redwing research projects.

Angus' outdoors skillset has carried him to many of the remotest parts of Scotland, including camping out to monitor dotterel, divers or capercaillie. Previously employed as an RSPB Research Assistant, he has worked on national hen harrier, montane bird and merlin surveys. He has worked for the BTO on Winter Gull Surveys (WinGS) and Non-Estuarine Waterbird Surveys (NEWS), as well as for several other ecological consultancies and private clients.

In addition, Angus has detailed knowledge of the status and habitat requirements of Scotland's rarest breeding birds and potential colonists. Also fascinated by migration, for five autumn seasons 2022-2026 Angus has volunteered at either Lundy or Skokholm Bird Observatory to assist with monitoring, expanding his experience to include scarce and rare passage migrants of the Western Palearctic and beyond. Angus also sits on the Highland Birds Rarities Committee.
