Report on scarce migrant birds in Britain in 2022

Abstract

It was, for the second year in a row, a record year for numbers of Ring-necked Duck in Britain. It was also a record year for Surf Scoter, Lesser Yellowlegs, Glossy Ibis and Purple Heron.

As well as providing a summary of the basic data for each species in 2022, the report includes charts and maps for some species not covered in detail in recent reports, mainly showing geographical distribution and phenology of records between 2008 and 2022, and annual totals since 1990.The summary statistics in this report have all been updated, including for earlier years if additional information has come to light since the last report was published. Both annual variation and trends have been recalculated for the period 1990–2022. Variation is based on the calculation of coefficients of variation1 but is expressed in purely descriptive terms in four categories: low, moderate, high an
