Notes: |
Capture day is not listed, so April 1 is arbitrary date before the release on April 5, 2005. In the 11 weeks subsequent to the release, 23 were resighted. Most were within the area, but two sightings were away from the release sites. One year after release, 11 of the translocation robins were known to have established in the study area - including 5 breeding pairs and a solitary male. This made 12 birds established during the 2005-2006 breeding season, where 40 eggs were laid and 57.5% successfully hatched (23) and 52.5% produced a fledglings (21). During the 2006-2007 breeding season, there were 14 robins in the study area, including a breeding pair from the initial translocated population and a juvenile from the 2005-2006 breeding season. In the 2007-2008 season, there was a violent storm with winds exceeding 140km/h/ The life cycles of the robins were upset and 6 0f 14 birds were no longer found; 3 females and 3 males are missing and were likely to be dead. The number of robins in the study area decreased from 14 in 2006/07 to 9 in 2007/08.
