Cormorant is the only likely confusing species in the UK, which larger and has an heavier bill but can be confused at long range.
Essentially a bird of the rocky coasts that does not range too far from shore.
In the UK it can be seen all year, mainly in north and west on rocky coast during the breeding season but tends to be more widespread in the winter with records from all around the coast, although it is still unusual away from breeding areas.
Adults probably dont stray far from breeding colonies, which can be deserted for a few months. Large winter concentrations in suitable habitat are not unusual.
It is a common breeding bird in the north and west of the UK with a slight range extension over the last forty years. Numbers of birds breeding each year does fluctuate but there has been a slight reduction in recent years.
It is a scarce winter visitor with the majority between August and February but it has been recorded in all months.
