MAP 12. The largely non- overlapping non- breeding distributions of two prion species and

the Blue Petrel from Iles Kerguelen, shown by yellow square. The black geolocator posi-

tions derive from Antarctic Prions (10 birds: 2,916 positions), red positions from Thin-

billed Prions (15 birds: 3,143 positions) and blue positions from Blue Petrels (12 birds: 2,237

positions). Also shown is the position of the Antarctic Polar Front. See page 162. Repro-

duced, with permission of The Royal Society, from the work cited in Note 24, Chapter 8.

MAP 13. The divergent routes of Antarctic peninsula and Terre Adélie South Polar Skuas,

respectively east and west of South America (blue arrows) and east and west of Australia

(green arrows). Birds from the Svarthamaren colony close to 0°E are not mentioned in the

main text, but they also migrate to two different oceans to escape the Antarctic winter, al-

though most go to the Indian Ocean. See page 65. Re-drawn from the work cited in Note

15, Chapter 4.
