Using lethal control to manage wildlife on airports

Martin Ziviani and Kylie Patrick discuss the complexities of using lethal control to manage hazardous wildlife on airports. 

How to do a bird count

Counting birds on airports is one of the standard elements of an airport’s wildlife management program. This data can be used to measure the progress and effectiveness of your program, identify emerging issues, and assess risks. But these counts need to be well established and implemented to have any benefit. Martin Ziviani (Snr Wildlife Biologist) joins Kylie Patrick (Principal Consultant) to talk about the how and why to set up and do bird counts on airports.

How to manage ducks

Alexandra Stone and Kylie Patrick talk all about duck management on and off airports. They cover active control, habitat management, and what land users around airport can do to reduce the duck attraction to the airport’s vicinity.

Managing off-airport hazards

Avisure CEO, Jeff Follett, joins Kylie Patrick to talk about how and why off-airport land uses can significantly elevate an airport’s strike risk because of the wildlife they attract. They talk about the types of land uses that are problematic and how to work with land users and land use planners to mitigate risks and safeguard airports.

How to manage Tree Martins

In one of our earlier Avicast episodes, we talked about a very small, but very common bird on Australian airports, the Fairy Martin. This little aerial forager is often mistaken for any number of little aerial foragers, including the topic of this episode, the Tree Martin. Alexandra Stone, Avisure’s Wildlife Biologist, is back in the co-host chair to talk all about the Tree Martin and how to best manage them.

How to manage Canada Geese

Kylie Patrick is joined by Avisure’s Principal Biologist, Will Jamieson and Wildlife Biologist Tyler Rogers to talk all things Canada Geese. These geese have been implicated in some of the most spectacular and serious strike incidents, and in this episode we talk about how to best manage them.

Wildlife strikes in a time of COVID

In April 2020 COVID-induced travel restrictions reduced aircraft movements by 80% globally, which was unarguably the greatest challenge the aviation industry has ever faced. But how did the sudden downturn in aircraft activity influence wildlife using airports? And what did this look like for strike numbers and rates?

Joining Kylie Patrick in this episode is aviation professional Dan Parsons who has been keenly analyzing strikes and aircraft movement data throughout the pandemic

How to manage flying-foxes

Dr Jeff McKee, Avisure’s Director of Research and Development, joins Kylie Patrick to talk about large bats called flying-foxes. Infringing critical airspace, sometimes in their thousands, they can present a serious strike risk, and are difficult for airports to manage, not just because of their numbers but also because they rarely use the airport itself. In this episode we introduce the flying-fox, why they are a strike risk, and how airports and other aviation stakeholders can mitigate their risk.

Why good data equals good management

As an airport, you may have in place a fully integrated and well-resourced management program, but … how do you know it’s working? The answer is data.
The most objective and informed way to measure the progress of your program is to review and analyse your data against the targets and goals you have set.
This data is varied, but may include things like wildlife strikes, wildlife dispersal and wildlife counts. But not all data is reliable, and not all data capture methods are equal.
Here to talk to me today about the importance of data and the best way to collect it is Avisure’s Wildlife Biologist, Alexandra Stone.


Dispersing wildlife on airports

Wildlife dispersal and harassment on airports is a fundamental component of a good wildlife hazard management program. But there’s a lot more to it than just chasing birds around airfields. Kylie is joined by one of our regular co-hosts, Martin Ziviani, to talk about dispersal and the principles required for effective wildlife control. We also briefly overview some of the tools and techniques available for wildlife controllers.   

Managing wildlife at Vancouver International Airport

Vancouver International Airport, Canada’s second busiest airport, sits on Sea Island in the Fraser River Delta where the marshes, mudflats and agriculture habitats on and around the delta attract millions of shorebirds, and thousands of waterfowl and gulls each year. To manage the wildlife strike risk associated with these hazards, Vancouver Airport have in place one of the most comprehensive wildlife management programs in the world. Joining Kylie in this episode to talk about their program is David Bradbeer, YVR’s Wildlife Program Specialist, and from Avisure Services, Tyler Rogers, who is the Site Manager for YVR’s wildlife management program.

Training for wildlife hazard management

When it comes to managing wildlife hazards on airports, you want to make sure that whoever is doing that management, knows what they are doing. And just like every other aspect of aviation safety management, training is critical. In this episode Kylie Patrick (Principal Consultant) is joined by Jeff Follet (General Manager for Avisure Services) and they talk about what training requirements look like around the world, and what it should look like. A must-listen-to episode for anyone that needs training and for those who are developing and delivering it. 

How to manage Australian White Ibis

Australian White Ibis (Threskiornis molucca) are a problem at many Australian airports, but managing ibis off-airport is the key to managing them on-airport. In this episode we join the collective experience from Avisure and our sister company Ecosure to talk about ibis management. Joining Kylie is Martin Ziviani (Senior Wildlife Biologist), and our very special guest Carla McKevitt (Ecologist) from Ecosure
