Males’ calls carry information about individual identity and morphological characteristics of the caller in burrowing petrels

We took morphometric measurements on males of two burrowing petrel species: blue petrel Halobaena caerulea (\"BP\") and Antarctic prion Pachyptila desolata (\"AP\"). We also provoked them with a playback and measured acoustic parameters on their provoked calls.

Fieldwork was performed in a small sub-Antarctic island (Ile Verte, 49°51′S, 70°05′E) of the Kerguelen Archipelago, in the southern Indian Ocean, where blue petrels and the during the 2017 and 2018 birds’ incubation period (25 November 2017 to 12 December 2017 and 27 November 2018 to 20 December 2018 for blue petrels; 23 December 2017 to 16 January 2018 and 25 December 2018 to 13 January 2019 for Antarctic prions).
