Great Cormorant

Great Cormorant colony in a pilar of the Freixo brigth crossing the douro river,in porto city.There a Grain Heron in the meadle of the cormoran colony i only see that at home.There are more than 100 birds at this hour of the day,but i suspect,by the flying formation movements that i see iduring all the afternoon in the brigth direction,that number will be exceded largely,i'll trie to spot the colony at the end of the dayligth next time
