While the Kereru (wood pigeon) is common in our area, we can go for weeks and not have any in our garden. At the moment they are frequent visitors with their two favourite food items being the dry seed pods on the Kowhai and Tree Lucerne flowers.
The Tree lucerne in our garden is a splindly bush and hardly a tree. The Kereru manage a range of gravity defying moves to get to the flowers. These city Kereru are also rather chubby!
