A large and conspicuous waterbird, the Cormorant has an almost primitive appearance with its long neck making it appear almost reptilian. In contrast, our recently established inland breeding population which is largely (but not exclusively) associated with the continental sub-species P. c. sinensis, increased rapidly following colonisation, but is now showing signs of stabilisation. The large difference in timing of breeding within an inland colony, means that competition for food when chicks are large is reduced. After diving for food, the cormorant will find a perch close to their feeding areas and sit with wings outstretched. I'm not sure about this one though. To make any difference to the cormorant population, it is estimated that 30,000-60,000 Research has found that the timing of breeding between the inland and coastal breeding birds is very different.
