Abstract

Little is known of bandicoot and bilby (i.e. Peramelemorphia) exploratory behaviour (e.g. activity in an open field arena). In a pilot study, we assessed activity of 14 adult male northern brown bandicoots (Isoodon macrourus) in a modified open field over two nights. While we found no consistent intra-individual variation, males in poorer body condition were in better breeding condition, suggesting a possible trade-off between reproduction and maintenance. Older males with larger testes and in better breeding condition reduced activity from Day 1 to Day 2, possibly to minimise energetic expenditure. Our pilot study of the exploratory behaviour of northern brown bandicoots suggests interesting avenues for future research in Peramelemorphia behaviour generally.
