opmerkingen 21 December to 20 April 2008, Engelenmeer, 's-Hertogenbosch, Noord-Brabant. The publication of discriminating characters between Continental Great Cormorant P c sinensis and Atlantic Great Cormorant (Newson et al 2004) triggered some observers to search for the latter in flocks of cormorants. This led to a series of reports, of which some have not yet been submitted. The strong increase in the number of records suggests that Atlantic is less rare than previously thought and it is most probably best regarded as a scarce visitor throughout the year but especially during September to March. Intriguingly, an adult was photographed on a nest in a Continental Great colony in Zeeland in May 2008 (not yet submitted) and a mixed breeding pair was discovered during spring 2009 in Friesland. Annual Report 2008.
