Band-rumped Storm-petrel (Hydrobates castro): vulnerability to climate change
Evidence for exposure
Potential changes in breeding habitat suitability:
-
Current breeding area that is likely to become less suitable (100% of current range)
-
Current breeding area that is likely to remain suitable (0%)
-
Current breeding area that is likely to become more suitable (0%)
Current impacts to Band-rumped Storm-petrels attributed to climate change:
-
There are no impacts of climate change recorded for this species
Predicted changes in key prey species:
No key prey species are predicted to decline for this species.
Sensitivity
-
Species is declining in many areas, range was likely much larger historically but has been greatly reduced by introduced predators. Any additional pressure from climate change is likely to accelerate these declines
-
Band-rumped storm-petrels rely on wind conditions to soar and use as little energy as possible. Changes in wind strength, direction and patterns could heavily impact energy use and migration paths.
-
Band-rumped storm-petrels have high breeding synchrony, the majority of birds in a population will breed in a relatively short period of time. If shifts in key prey availability occur it could have significant impacts on breeding populations
-
This species has a long generation length (>10 years), which may slow recovery from severe impacts and increases population extinction risk
Adaptive capacity
-
Species has very high fidelity not only to breeding areas, but to burrow itself. Unlikely to disperse and colonise new areas readily in response to climate change.
-
There is very limited mixing between populations in storm-petrels, this can be adaptive (as it increase likelihood of local adaptation) or non-adaptive (as immigration to support populations is unlikely).
