The 1984-88 survey found Mistle Thrushes to be more numerous in the south and north east of the county than elsewhere. The 2003-07 survey shows a much more even distribution across the whole area, other than remaining thinly spread in the far west, over all amounting to a 29% increase. The BBS calculated a 6% increase in Wales between 1994 and 2007. Applying this to the 2003-07 records for Pembrokeshire suggests a breeding population of about 1,900 pairs compared to the estimate of 1,400 pairs during the previous survey.
