Captive management has the potential to make a significant
net contribution to future Brown Teal recovery, in spite of
initial concerns that a captive population would be a net
consumer of birds and about the lack of pedigree records.
Captive Brown Teal have been shown to have a long productive
life, and productivity can also be enhanced by management
techniques such as multiple clutching, artificial incubation
and brooding, and cross-fostering, all of which have been
used successfully.
The goal of the Brown Teal Captive Management Program is
to maintain, manage and develop the Brown Teal captive breeding
programme to retain known genetic diversity, annually supply
known quality birds for release in the quantities and at the
times required by the recovery programme, and to contribute
to Brown Teal advocacy.
At least 2000 birds have been reared in captivity since 1964.
These have originated from just 76 wild birds. Within the
first 32 years of Brown Teal captive breeding had resulted
in 21.5 birds being released for every wild bird taken into
the programme. In terms of numbers of birds
available to be recruited into a wild breeding population,
the captive population is more than 300% more efficient at
producing these birds than are wild populations
Without doubt, captive management has the potential to make
a significant net contribution to future Brown Teal recovery.
Captive Brown Teal have been shown to have a long productive
life, with one bird surviving for 22 years.
