• Resumen

  • This note constitutes the first published observations of Bearded Vultures Gypaetus barbatus ingesting their pellets immediately after regurgitating them. The explanafion for this recycling of pellets may be that the birds make use of the bone remains that they contain and that have not been totally digested previously.
