Subject: REGENT HONEYEATER at Cooleman Ridge NR
To: Birding-aus <>
Further to John Leonard's message yesterday, the following extra
information is from David Geering:
In response to John's questions about movements of Regent Honeyeaters:
There are essentially three major (or core) breeding areas - Capertee
Valley, Bundarra-Barraba and Chiltern. Breeding can occur almost
anywhere in the breeding range at times (Canberra in 1995 for
example). It is unclear as to whether we really have discrete
breeding populations, although there is good evidence that there is.
Having said that, there is also evidence that there is actually one
mega population.
We have no individually colour-banded over 500 Regent Honeyeaters
(although by far the majority of these were banded in the Capertee
Valley). There have been some very interesting long distance
movements including:
Capertee Valley, NSW 26-10-94 to Chiltern, Vic 21-07-01 472 km
(6yr8mth25d)
Watson, ACT 15-12-95 to Capertee Valley, NSW 08-03-98 269km
(2yr2mth21d)
Watson, ACT 16-12-95 to Capertee Valley, NSW 08-10-97 258km
(1yr9mth22d) bred at both locations.
Barraba, NSW 08-04-95 to NSW Central Coast 17-07-02 355km (7yr3mth9d)
Cement Mills, Qld 10-09-02 to Capertee Valley, NSW 08-09-08 534km
(5yr11mth29d)
There are also numerous movements of Regent Honeyeaters recorded
50-120km from the banding location and many more in the general area
of the banding location some time after banding. Some of these
longevity records include:
Capertee Valley, NSW 21-06-97 to Capertee Valley, NSW 17-08-08
11yr1mth27d (14km)
Howes Valley, NSW 14-08-94 to Capertee Valley, NSW 07-09-04 10yr0mth24d
(58km)
Chiltern, Vic 03-11-89 to Bobinawarrah, Vic 21-10-99 9yr 11mth13d
(43km)
Chiltern, Vic 10-11-88 to Chiltern, Vic 01-09-98 9yr9mth21d
There are obvious others that range up to the elapsed time shown above
(some of those on the first table for example).
The above information needs to be interpreted with care, particularly
the movement data. Just because we have birds moving between the core
breeding areas does not necessarily mean there is free and regular
exchange. We do not have enough data to support that. In fact, the
data set, when viewed in its entirety, suggests that most birds return
to the same general breeding area with only some genetic interchange
between them.
It is a complex picture and we may never entirely understand it but
pieces are coming together.
