Both these birds were photographed in the same outdoor area and only a couple of minutes apart. This one has all black plumage whereas the previous one has bluish body plummage and a grey head, which is why I wouldn't have connected them as the same species. However looking at images on the net it seems that these different plumage colours do occur.
