Suffolk Rookery Survey
The Rook is one of Suffolk’s most recognisable birds, nesting in noisy colonies – rookeries – typically in tall trees on the edges of villages and farmland. Rook populations have declined in parts of eastern England, largely because changes in farming practices have reduced the availability of the short grassland and arable fields they depend on for feeding. SBIS has been collecting nest count data from Suffolk’s rookeries for a number of years, building a long-term picture of how colonies are changing in size and distribution. If you know of a rookery, please record it – even a note that a colony appears unchanged from previous years is useful data.
