Notes:

Viewing and download access to this dataset is restricted for the following reason. The information held within this dataset relates to a threatened bird in the UK that may be vulnerable to human disturbance, habitat loss or other factors. At this time, we believe that full disclosure to the public may lead to environmental harm. This sensitive information may be made available under licence to specific organisations and individuals that need to use them for conservation work or to avoid harm to the environment.

Description
This dataset was compiled to monitor the population and productivity of red-necked phalaropes in the UK. more

Red-necked Phalaropes are diminutive waders with a small and fluctuating UK population. Monitoring has taken place on an ad-hoc basis since 1972 with an increase in coverage of the western isles in recent years. This dataset contains all records from this monitoring along with productivity data.

Breeding data were collected in most years through the RBBP and local staff of both SNH (formerly NCC) and the RSPB. From 1992 onwards visits to find nest sites on Shetland were more frequent and included colour-ringing of young.

The likelihood that phalaropes were breeding is grouped into three categories:

  • Confirmed - by presence of a nest, sighting of pre-fledged chicks or males displaying/acting as if with young
  • Probable - if males present on a known/likely breeding site for 7 or more days and were associated with a female for all or part of that time
  • Possible - if a pair or male were reported at a known/likely breeding site for 7 days or less

Records are given here at 100m resolution, which represents the centroid of the site. Where the exact site is unknown, 1km or 10km resolution grid references are used.

These data have been gathered by trained field-workers and the data are of a high quality. These data have been mapped and checked for sensitivities and typographical/geographical errors.
