AGGRESSIVE BEHAVIOUR DISPLAYED BYTHE GREY-NECKED FRIARBIRD.By John Bowler & John Taytor(Received 31 January 1989)On 18 August 1987 at an attitude of 550m on the north face of GunungKobipoto in the Manusela National Park, Seram, a pair of Red Lories Eosbornaa was attacked by a Grey-necked Friarbird Philemon subcomiculatuswhilst inspecting a nest hole.The Red Lories were watched for a period of 135 minutes, and one of the pairwas observed to enter a nest hole, 25m up a mature forest tree on fiveoccasions, while the second bird remained perched just outside the hole. Onthree separate occasions a Grey-necked Friarbird, which had been callingfrom an adjacent tree,, mobbed the perched Lory. The mobbing consisted of avigorous downward flight swooping at the Lory causing it to visibly duckits head. On the third occasion the mobbing was persistent and vigorous,the Lory being physically struck from behind four times and pushed alongthe perching branch away from the nest hole. The Lory became increasinglyagitated, emitting a "meati, meep" alarm call, before finally leaving thesite, closely followed by the second bird which flew out of the hole.The area was revisited the next day when the Lories were again noted to bepresent at the nest hole. However, the Friarbird was calling some distanceaway from the site and no further interactions between the two species wereobserved.Such vigorous interspecific interactions are rarely recorded, and usuallyinvolve small birds mobbing larger birds which might be perceived aspossible predators. The Grey-necked Friarbird is distinctly larger thanthe Red Lory and the observed attacks may possibly represent a form ofterritorial defence.Address:c/o.
