I’ve often seen Shags in public places of Auckland in groups or one on their own. Just about all of my photos are Pied Shags which are black and white Shags.
They are seen in trees in estuaries or some trees by Western Springs Ponds by Pt Chevalier in Auckland, and even saw one by the Waterfront by the rocks. Often seen them on rocks near Mangere Bridge near Onehunga.
Pied Shags live by Coastal places throughout most of New Zealand, North and South Island.
Generally Pied Shags will forage for fish by themselves in the water. Sometimes they hunt in groups. I saw a whole lot of Pied Shags in a bridge by Karaka, South Auckland. The Pied Shags would fly under the bridge and dive for fish, then they would be back in the same place as before and fly again under the bridge to catch more fish. To do this, they must have been very successful that day.
