The July 2013 issue of British Birds contains the first part of the Report on Scarce Migrant Birds in Britain in 2004–2007.
This report presents data on scarce migrant birds in Britain between 2004 and 2007. Sixteen of the 17 species removed from the BBRC list at the end of 2005 are included here for the first time (Ferruginous Duck was treated in this report from 1995 to 1998), while ‘Black Brant’ also makes its first appearance here. Some species appeared in record numbers during this four-year period, while others fared poorly. The long-term trends for several species, in particular waders and several passerines that breed in Europe, show a gradual decline, whereas Nearctic waterfowl and waders, together with passerines from Siberia, are generally increasing. Species doing well included Green-winged Teal, Great White Egret, Black Kite, American Golden Plover and White-rumped Sandpiper. In contrast, Tawny Pipit fared especially poorly while numbers of Ferruginous Ducks, Red-footed Falcons, Red-throated Pipits and Rustic Buntings also fell. Many species in this report have now been monitored for 40 or 50 years, making this a robust and valuable dataset for investigating long-term changes in populations, distribution and movements.
