Along with recording mammal activity. British Trust for Ornithology had requested that data on birds nests also be recorded. All nest box recording activity was undertaken with respect to suitable licences, and supervised by a licence holder for each cohort of surveyors.
Mammal species found by this survey cohort were hazel dormice and wood mouse (Apodemus sylvaticus) - different nest structures were found including woven unstructured, woven structured, brown leaf nest.
Bird's nests were identified as blue tit (Cyanistes caeruleus), great tit (Parus major) - not shown - and wren's (Troglodytes troglodytes). Seperating the first two types of nest was not as easy as the descriptors indicated, as crossover of features was noted when birds were present - as such where birds were not present ID may have been more subjective.
Bee's nests were also found in the nest boxes, the only bees found by this survey cohort was later identifed as belonging to the tree bumblebee (Bombus hypnorum) a recent colonist to the UK - first found in Wiltshire in 2001.
