Abstract: Anthropogenic debris is ubiquitous in the marine environment
and has been reported to negatively impact hundreds of species globally.
Seabirds are particularly at risk from entanglement in debris due to
their habit of collecting food and, in many cases, nesting material off
the ocean’s surface. We compared the prevalence and composition of
debris in nests and along the beach at two Brown Booby (Sula
leucogaster) colonies on Ashmore Reef, Timor Sea, a remote area known to
contain high densities of debris transported by ocean currents. The
proportion of nests with debris varied across islands (range 3–31%),
likely in response to the availability of natural nesting materials.
Boobies exhibited a preference for debris colour (white and black), but
not type. The ephemeral nature of Brown Booby nests on Ashmore Reef may
limit their utility as indicators of marine pollution, however
monitoring is recommended in light of increasing demand for plastic
products.
