Species to be removed from the BBRC list

Despite the removal of a number of species in 2006 (Brit. Birds 99: 52 & 100: 18-19), the number of records received continues to grow and we assessed the frequency of several of the more common rarities at the AGM. White-billed Diver Gavia adamsii met the statistical criteria for removal from the list (more than 150 records in the last ten years, with 10 or more in at least eight of those years) for the period to the end of 2008 and will therefore be dropped from the list of species considered from 1st January 2009. Cattle Egret Bubulcusibis met the more than 150 criteria, but fell short of the 10 or more per annum threshold. Nonetheless, given that the influx which began in autumn 2007 appears to be being sustained, and that the species is relatively easy to identify, it was determined that it would also be dropped from the list of species considered from 1st January 2009. Parrot Crossbill Loxia pytyopsittacus was also considered. Although reports of this species to the Committee have been nowhere near the frequency to be considered for review, the widely publicised Scottish breeding population (see Brit. Birds 95: 4-11; Ibis 144: 393-410) appears well established. Ron Summers has provided the Committee with summary data for Parrot Crossbills trapped during his study and we are grateful for this information, which allowed us to confirm the identification of these individuals. We will therefore not be seeking records of this species from 1st January 2009 onwards, but will also not assess retrospective records as a consequence of the established breeding population. We would like to take this opportunity to remind local committees that BBRC is willing to assist with the assessment of any previous BBRC species, if necessary. Any requests should be directed towards the Secretary.
