Advice on conservation issues
2018. Consultation with the federal Dept. of Environment and Energy in regard to the Grey Falcon's national conservation status (EPBC Act 1999).

2016. Advice provided to BirdLife International, 2016 Red List Update, in regard to Falco hypoleucos Grey Falcon.
Reference: IUCN Red List, species listing: Falco hypoleucos

2012. Advice to the Queensland Dept. of Science, Information Technology, Innovation and the Arts on the conservation status of the Grey Falcon for Queensland, provided to Dr J. Thompson. I proposed to re-classify the species from ‘Near Threatend’ to ‘Vulnerable’ on the basis of the population size estimate of fewer than 1000 mature individuals.
Outcome: remained ‘Near Threatened’ (Nature Conservation (Wildlife) Regulation 2006, 27 July 2012).
On 28 August 2015 the species was up-graded to ‘Vulnerable’.

2010-2011. Advice to IUCN/BirdLife International on the conservation status of the Grey Falcon, provided to Prof. S. Garnett, Carles Darwin University.
Outcome: re-classified from ‘Near Threatened’ to ‘Vulnerable D1’ (fewer than 1000 mature individuals), following my recommendation.
Reference: BirdLife species fact-sheet: Grey Falcon Falco hypoleucos

2010. Advice provided to Prof. S. Garnett, Carles Darwin University, on the conservation status of the Grey Falcon, for consideration for The Action Plan for Australian Birds 2010.
Outcome: re-classified from ‘Near Threatened: d’ to ‘Vulnerable D1’ (fewer than 1000 individuals), following my recommendation.
Reference: Garnett, S.T., Szabo, J.K. and Dutson, G. 2011. The Action Plan for Australian Birds 2010. CSIRO Publishing, Melbourne.

2009. Advice provided to the NSW Scientific Committee, concerning the conservation status of the Grey Falcon for NSW.
