Sun, Mar 18, 2007 Ponui Island Field Work 3 - Kiwi Foraging Behavior Research It was belived that kiwi is an aggressive, territorial, solitary bird. But we could observe a strong pair bonding in a few couples. they share the nest and forage togather. Usually female comes out of the nest first and male follows about half an hour later. Before leaving the nests, we could hear them communicating by purring (like a cat), pleening - taking long time to get ready for hunting breakfast. 作成者 kyo [ コメント : 11] Ponui Island Field Work 2 - Kiwi Foraging Behavior Research Radiotracking kiwi in the daytime, when they are sleeping in the nests. after confirming their nests, set up the video camera and come back later when the sun sets down, about 8:00pm in this time of year. Currently about 40 birds are wearing transmitters and detectable by radiotracking. 作成者 kyo [ コメント : 0] Ponui Island Field Work - Kiwi Foraging Behavior Research Pnui island is located in Hauraki gulf, Auckland, right next to Whaikehe Island. Hundreds of kiwi birds are living in the regenerating bush. The most destructive predetors such as stoats and ferrets have been eradicated from the island, however, the rats, cats, dogs and cattels are still on the island. Nevertheless, the population of kiwi has been increased to the level of almost carrying capacity and dense. Interestingly, intensive pair bonding between male and female was observed. My mission was to assist the researcher studying kiwi foraging behavior, finding kiwi nests by radiotracking, filming kiwis when they forage, changing transmitters on there legs, etc. 作成者 kyo [ コメント : 0] Sat, Mar 17, 2007 Bushy Park Field Work4 6 month old Kiwi captured for changing the transmitter and periodical measurement. This particular bird on the photo weighted 900g with its beak length 6cm. All kiwis in the Bushy park are still young chicks translocated from a captive kiwi house, Kiwi Encounter, Rainbow Park in Rotorua last spring, when predator free environment was set up with the completion of fencing. This fall, about a dozen of new chicks from the kiwi house will be planned to be relocated into the park. 作成者 kyo [ コメント : 0] Bushy Park Field Work3 Tree Weta on the fence 作成者 kyo [ コメント : 0] Bushy Park Field Work2 2 days old Saddle back chicks in the nest 作成者 kyo [ コメント : 0] Bushy Park Field Work Saddle Back Monitoring 2 days old Chicks 作成者 kyo [ コメント : 0] 前の記事  |  次の記事
