Manx shearwater tracking data from Bardsey and Copeland in 2022 and 2023
Abstract
Manx shearwaters' foraging movements were tracked during the breeding seasons of 2022 and 2023 from two colonies: Bardsey (North Wales) and Copeland (Northern Ireland). 247 tracking sessions were recorded in total, with 57 and 40 shearwaters tracked from Bardsey and Copeland respectively in 2022, and 63 and 62 shearwaters tracked from Bardsey and Copeland respectively in 2023. Tracks were recorded using AxyTrek tags produced by TechnoSmart. Tags recorded location (latitude/longitude), tri-axial acceleration, and pressure, which has been converted to depth (in metres). Data were generated by converting files downloaded from the loggers using the tag manufacturer's software. Data were collected between May and August each year (during the breeding season for Manx shearwaters). Breeding Manx shearwaters were captured at their nests and equipped with Axy-Trek loggers, attached to birds' back feathers using TESA tape.

| Data lineage: |
Breeding Manx shearwaters were captured at their nests and equipped with Axy-Trek loggers (TechnoSmart Ltd, Rome), attached to birds' back feathers using TESA tape. Birds were released and then recaptured after several foraging trips (usually between 2-14 days after deployment) to retrieve the tag and download the data. Tags collected GPS fixes, tri-axial acceleration, and pressure. Data files downloaded from tags were converted using X Manager, custom-built software for using Axy-Trek devices provided by the manufacturer. X Manager was used simply to convert compressed files into csv files, allowing access to locations, acceleration and pressure data. Pressure data were converted to depth (in metres) during processing. |
