The following changes have been made to the British List. 'Taiga' Merlin Falco columbarius columbarius Linnaeus Add subspecies F. c. columbarius † Linnaeus to the British List One, second-calendar-year or older, Burnside, Scrabster, Caithness, 3-18 February 2018 (photographed). Published material indicates that the tail-banding of this individual is diagnostic for various Nearctic subspecies of Merlin, including nominate F. c. columbarius. Another Nearctic subspecies F. c. richardsonii was excluded because of the dark colour of the upperparts of the Caithness bird. F. c. columbarius is also the more likely trans-Atlantic vagrant, based on its eastern North American distribution and migration patterns. The probability of this individual being an escape from captivity was judged to be very low, and the subspecies has been recorded previously elsewhere in the Western Palearctic as a trans-Atlantic vagrant. Polytypic, breeding across the Palearctic and Nearctic regions, with northern populations moving south during winter. 'North American' Horned Lark Eremophila alpestris (alpestris/praticola/hoyti) (Linnaeus/Henshaw/ Bishop) Add subspecies E. a. (alpestris/praticola/hoyti) † (Linnaeus
