This is the call of the elusive Ashy Storm-Petrel (Oceanodroma homochroa). Ashy Storm-Petrels nest in burrows and crevices on offshore rocks and islands. To avoid predators, they only arrive and depart their island nests under the cover of darkness. That makes studying them pretty difficult.

Amphibians’ permeable skin makes them incredibly sensitive to changes in their environment. Scientists and conservationists alike are using them as “sentinel species” that could provide early warnings of ecosystem change and stress affecting them and other organisms. Next time you are out, stop and listen. Do you hear them?
