Easy to confuse with shags, usually cormorants will have a white patch, as seen in the image above, around the thigh and also cormorants are more likely to be found inland even at lake and river sites.
Shags have a steeper forehead rising from the bill which is marked by a crest of feathers and almost always in Ireland remain coastal.
If you are wondering how seabirds get airborne, here's an interesting sequence from the west of Ireland.
Quite a sight, a fine sunny summer's day and the sounds of wildlife all around.
Finally airborne.
Seagulls in general may be associated with loud, aggressive food stealing behaviour but herring gulls are currently on the UK's Red List for endangered species.
In Northern Ireland, herring gulls experienced a population increase during the 1950s-1970s, in the Seabird Colony Register census from 1985-1988 there were 17,561 pairs of herring gulls in NI while in a follow-up survey, the Seabird 2000 census, only 722 pairs were recorded.
Ireland has lost large numbers of herring gulls in recent decades and it would seem that the western coasts of Ireland and Scotland have seen the largest declines in herring gull numbers in recent decades.
Young fulmars spend five years fully at sea, coming back to land to choose a colony after that but even then they won't breed for another few years. They can live for over forty years.
In this image you can see the tube-nose from which the tubenose family get their name, the birds possess a gland which helps to process, store then eject saline through the tube - salty water collected when diving for fish in the north Atlantic.
Recent weeks have seen me photographing nightlife rather than wildlife at many concerts in Dublin and Belfast, including Whitesnake, Queen and Bryan Adams.
Each year the fulmar will return to the same ledge on the same cliff and will often mate for life. It lives for over 40 years and is a pelagic feeder of any type of fish.
The upper feathers are grey with brown feathers often visible, though most guides fail to mention these they are very evident in the image above. Undersides are white and the fulmar has a distinctive blue portion of the nose.
The fulmar is one of Ireland's fascinating seabirds, fantastic when seen in flight.
