Red-legged Cormorant

There's 2 different bird species, in this spotting...There is the Red-legged Cormorants with their build nests, along with the non-breeding adults of the species, and there's the Peruvian boobies too. So I guess I can suggest both IDs, and later you can separate the species in 2 different spottings, even using the same image (I suppose you are allowed to do so, as long as you will include a description... :)
