Movements and distribution of inland breeding cormorants in England (ENRR360)

Numbers of cormorants Phalacrocorax carbo breeding inland in England have increased markedly over the past 18 years. Since first breeding inland at Abberton Reservoir, Essex, in 1981, numbers have increased at a mean of 35% per year to reach 1,437 pairs at 23 sites in 1998. The availability of suitable breeding sites suggests that numbers of cormorants breeding inland in England will continue to increase for the foreseeable future.
