<\/a><\/p>\n “In early December 2012, a small colony of 25\u201330 Purple Herons (Ardea purpurea<\/em>) was observed as they roosted up amongst the contiguous crowns of mature raintrees (Albizia saman<\/em>) in Perak, Peninsular Malaysia (above).<\/p>\n “This heronry was a hive of activity, as birds regularly flew in and out of the treetops, leaving for and returning from their feeding sojourns. There was also constant communication between the members of this colony, as multiple cues were being sent to each other in the form of various displays. The intentions of such advertisement displays may be to: <\/p>\n (a) pronounce its claim over a particular nest-site, “In this heronry, a vast majority of the birds (80\u201390%) were adults adorned with breeding plumage in all their splendour. The base of the bills also took on a reddish hue.<\/p>\n <\/a><\/p>\n “One of the most common gestures was the erection of its head and neck feathers (above). This may be accompanied by the inflation of the throat region.<\/p>\n
\n(b) ensure the neighbours maintain a respectful distance,
\n(c) advertise its attractiveness\/fitness to the respective breeding partner. <\/p>\n
