There were 53 recaptures of birds that had been ringed prior to 2000.
These recaptures comprised of 18 species.
The Common Redshank leads the list with 24 recaptures, followed by
the Collared Kingfisher with 7 recaptures and Brown-throated Sunbird
with 4 recaptures. One use for the data obtained from recaptured birds
is the establishing of longevity records and enabling the active survival
of bird species to be determined. The longevity records are listed
in Table 2.
Of interest, the oldest recaptured bird was a Common Redshank. It
was ringed in the Park on in Nov 90and recaptured on 27 Nov 00. The
interval of just under 121 months (slightly over 10 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 Aug 00, an interval of 72 months (6 years).
One Black-capped Kingfisher exhibited high site fidelity. It was mist
netted at the same net location and even the same section of net after
an absence of one season. Ringed in Mar 00 and recaptured once in
Nov and Dec, the capture data suggest that the Park locality is its
ultimate wintering area.
A Philippine Glossy Starling recovered on 19 Jul 00 at the Visitor
Centre had been ringed at the freshwater pond area on 15 Aug 94, about
72 months (6 years) earlier suggesting that frugivorous type birds
do remain in the Park vicinity even after a number of years. |

Shorebirds
were colour-marked with yellow dye and their movements within the
Park and throughout Singapore were recorded based on ad hoc observations
by the Park's network of volunteers and friends. Some of the interesting
sightings of colour-rnarked shorehirds are listed in Table 3 (below).
Of interest is a record of a yellow leg-flagged Common Sandpiper believed
to have been ringed at Broome, NW Australia and reportedly sighted
in the Park on 30 Sep 00. |
