  Jam sessions in the avian world, rather than drawing a crowd, keep out
  pesky intruders, new research suggests.

  And magpie-lark duets with the most rhythm present a more threatening
  deterrent than those whistling off beat.

  "When partners sing, they signal to other magpie-larks that they are
  working as a team to defend their territory," said co-researcher Michelle
  Hall of the Max Planck Institute for Ornithology in Germany.
