Shags, sometimes also called cormorants, are diverse in New Zealand, with around eleven species occurring here. Shags are mainly coastal species. Consequently, they are less likely to be recorded by observers at sea.
Mean number of shags recorded around fishing vessels during
counts carried out by government observers, binned to 0.4 degree of longitude and latitude. The size
of the circle indicates the number of observations, whereas the colour indicates the
mean number of birds recorded during counts. Empty circles indicate that no birds were observed. The grey
areas indicate water depths of less than 1000 m.
