I had some time to occupy in Bishopbriggs today so I squeezed in bird surveys of two ajoining 1km squares. This is a good time of year to count birds as many species are singing or carrying out other activities associated with the breeding cycle. Some interesting records included a single Oystercatcher flying low over houses near the sports centre, a Little Grebe "trilling" on the canal and at least four Rooks' nests in Bishopbriggs Park. A tatty Peacock butterfly was nearby and flowering plants included Slender Speedwell, Greater Stitchwort, Yellow Archangel and Garden Solomon's Seal.
