Uso de la cola y el marsupio en Didelphis marsupialis y Metachirus nudicaudatus (Didelphimorphia: Didelphidae) para transportar material de anidación

Information about the use of tail to carry nesting material by Neotropical marsupials is poorly documented. Based on videoclips obtained by camera traps, we documented the behavior of gathering and carrying nesting material in curling tails by Didelphis marsupialis and Metachirus nudicaudatus. Additionally, we documented for the fist time an individual of D. marsupialis gathering leaves and other nesting material in the pouch. This is the first documentary evidence of the use of the marsupium for other activities than lactation and protection of pouch youngs.
