Peter Fullagar and Chris Davey - The Rodent eradication program on Lord Howe Island - the COG contribution

There will be another virtual meeting at 7:30 pm on 11 November. The following is the webinar link:

Participants should be encouraged to register at least 30 minutes prior to 7.30 pm. They will need to have their video and sound working on their computer. During the webinar participants will be able to see and hear the presenters but not talk. Feedback will be via a typed live chat (which has about a 20 second delay). The webinar is scheduled to last up to one hour.

Following the AGM the presentation for the evening will be by long-term COG members Peter Fullagar and Chris Davey titled “The Rodent eradication program on Lord Howe Island – the COG contribution”.

After many years of planning and delays baiting with the rodenticide Brodifacoum was successfully completed on Lord Howe Island during the winter of 2019.

The Canberra Ornithologists Group has been involved in the program since 2013. The Group has been responsible for the design and coordination of an annual survey of the lowland land birds since that time. The aims of the survey have been to determine the effects of the baiting program on the terrestrial birds after the initial baiting regime and in the long-term.

The talk will discuss the problems associated with introduced rodents on islands, with examples of past successes and failures, how COG became involved, briefly introduce the survey methodology and then present some preliminary results and implications for rodent control on other islands.

Fifty seven Canberra families and individuals are participating in an ongoing study that has identified and observed Gang-gang breeding hollows. The talk will present findings on hollow choice, breeding ecology and concerns that increased temperatures may be impacting on chick survival.
