Yesterday (2nd May) we did a fruitless yellowhammer survey of SS09P tetrad near Jameston. Variety and numbers of most birds seen were quite small but included lesser whitethroats in a couple of places. Various insectivorous species, such as whitethroats, pied wagtails and others were feeding on numerous St Marks flies and other insects attracted to a rich nectar source in bright yellow fields of oilseed rape. However, the flowers they were visiting were being sprayed with chemicals at the time; probably not so good for pollinator insects or for feeding birds!
