Abstract:Successful conservation depends on an understanding of dispersal patterns for spatially
complex species. Among seabirds there are opposing pressures to either disperse or return to
natal colonies. We explored philopatry across 36 species, based on banding and census data.
Philopatry correlated with foraging strategy, taxonomy, and region, suggesting that translocation
will be more successful for Procellariiformes, those in tropical regions and with non-central
foraging strategies, as they are more likely to return to translocation sites. Additionally, we
compared genetic diversity between two orders of seabirds with differing philopatry and
explored population genetics of a species in the order Procellariiformes, the Band-rumped Storm
Petrel (BSTP; Oceanodroma castro). Findings indicated no difference in genetic diversity
between orders and high genetic diversity within BSTP. Although this study suggests that BSTP
are not at risk genetically, they remain vulnerable to threats. Management efforts to ensure
successful nesting is crucial to recover the endangered BSTP.
