A Little Black Cormorant also clambered on to the wharf and then onto the bottom rung of the fence where the Little Pied Cormorant was. There was no trouble between the two species, they were content to let the other be. Like the Little Pied Cormorant, the Little Black Cormorant also entered the lake when the two people walked along the wharf. The Little Black Cormorant swam closer to the bank where I was than the other cormorant. It was not worried by my presence but went under water again and came up slightly further out in the lake. It did not stay submerged long when it was under water, maybe 5-10 seconds.
