Compared to last year's ringing effort, the number of Javan Munia had increased by 55%. This is attributed to the replanting of Panicum maximum whose seeds form the bulk of food for the Munias. A number of the replanted grasses was in the vicinity of the netting sites.
One use for the data obtained from recaptured birds is the enabling of longevity records and the active survival of bird species to be determined. These records are provided in Table 2. Of interest, a Marsh Sandpiper ringed on 31 Oct 90 and recaptured in the reserve on 23 Jan 01, an interval of just under 123 months, beat the previous record held by a Common Redshank by 2 months. However the record was wrested back by another Common Redshank later in the year. This individual was ringed in the Park on 30 Oct 01 and recaptured on 29 Nov 01. The interval Of 133 months (11 years) is believed to be the longest recorded for the species. The oldest recapture of a non-migrant was a Collared Kingfisher ringed in Jul 94 and recaptured in Jun 01, an interval of almost 84 months (7 years). This is the same individual that held the previous record of 73 months (6 years) as was reported in the bird ringing report for 2000.
One Black-capped Kingfisher exhibited high site fidelity. The individual that was reported mist netted at the same net after an absence of one season in the bird ringing report for 2000 returned (in the same net F6 even in the same section of net) on 10 and 23 Oct 01. It is possible that the reserve locality is its ultimate wintering site.
A Black Bittern was recaptured at the same wintering area 11 months after it was ringed at the freshwater ponds. Similarly, a Yellow Bittern was also recovered 94 months after it was first ringed. This is the first direct evidence that the reserve is a wintering area for these two species.
Some movements of birds were noted within the reserve. Notably, a Collared Scops Owl that was ringed at the western end of the park was netted in the Visitor Centre area at the eastern end. Similar movements were also noted for a Stork-billed Kingfisher.
In summary, bird ringing in 2001 has, for example, continued to reveal surprises in bird Movement, abundance and survival rates. Data collected are invaluable for the long term conservation management of the Park.
This article is possible because of the field studies supported by NParks. Thanks to fellow ringers Ramakrishnan, Linda Goh, Cheryl Chia, Benjamin Lee, Genevie Chua, Charles Lim, Patricia Phua, Ali lbrahim, Joseph Lai and Chan Su Hooi for contributing to the ringing work. Many others assisted with the ringing including staff, volunteers and friends especially, Kunasegaran and Halilah Ahmad. In addition I am grateful for the voluntary help from Nick Baker, Lua Wai Heng and Zeehan/ Kenneth Kee, R. Subaraj, Richard Ollington and Alan Owyong gave expert advice and contributed some sighting and observation records.
