MAP 4. Each pair of maps shows the activity of Manx Shearwaters on their differently- routed north-
bound (left) and southbound (right) journeys between the Welsh colony and the wintering areas off
South America. The three pairs show respectively where resting, flying and feeding are concentrated.
Note, for example, how there are favoured feeding grounds off the eastern United States when birds
are northbound in spring, and a resting area in the central North Atlantic. See page 70. Reproduced
