MAP 10. The foraging loca-
tions (pink circles) reached by a
Black Petrel during an excur-
sion from the colony on Great
Barrier Island (black star) off
New Zealand’s North Island.
Foraging was concentrated near
the shelf break where the sea-
floor is 600– 1000 m deep and
starts to fall away rapidly (red
contour lines) from the conti-
nental shelf towards the deepest
ocean. See page 150. Re produced

MAP 11. A map showing the distribution of four Brünnich’s Guillemots, each represented
by a different colour, across two winters, one unshaded, the other hatched. The birds bred
in colonies to the north of the mapped area. There are two examples of birds that used
very similar areas from one winter to the next (black and orange), and two more that used
very different areas (blue and red). See page 139. Re-drawn and reproduced under the Cre-
