Spearman’s rank correlation, and associated 95% confidence intervals, between penguin abundances and calculated connectivity metrics within each region illustrated in Figs. 3 and 4.

Penguin species	Connectivity metric
	Transit time	Time in region (released within)	Time in region (released outside)
Adélie	− 0.4 (− 0.9 to 0.7)	0.7 (− 0.5 to 1)	0.7 (− 0.5 to 1.0)
Chinstrap	0.5 (− 0.6 to 1.0)	− 0.9 (− 1.0 to − 0.1)	− 0.6 (− 1.0 to 0.6)
Gentoo	0.2 (− 0.8 to 0.9)	0.1 (− 0.9 to 0.9)	0.4 (− 0.7 to 0.9)
All	− 0.4 (− 0.9 to 0.6)	− 0.3 (− 0.9 to 0.7)	− 0.2 (− 1.0 to 0.9)
