Modeling habituation of introduced predators to unrewarding bird odors for conservation of ground‐nesting shorebirds

Abstract: Foraging mammalian predators face a myriad of odors from potential prey. To be efficient, they must focus on rewarding odors while ignoring consistently unrewarding ones. This may be exploited as a nonlethal conservation tool if predators can be deceived into ignoring odors of vulnerable secondary prey. To explore critical design components and assess the potential gains to prey survival of this technique, we created an individual‐based model that simulated the hunting behavior of three introduced mammalian pr… Show more

“…Olfactory cues that signal danger, such as predator odour [27] or territorial scent marks [28], can reduce the impacts of pests. Though examples are rare, applying odour cues can change pest behaviour, such as camouflaging native prey to reduce the impacts of invasive predators [29,30] (Figure 1A,iii).…”

“…Bird odour could be used sparingly as a novel lure to attract snakes to control devices, especially larger BTS shown to be refractory to mouse lure (Yackel Adams et al 2019). Alternatively, managers could deploy bird odour across the landscape to camouflage endangered birds through olfactory swamping or odour priming (Ruxton 2009;Banks 2012, 2017;Latham et al 2019;Norbury et al 2020).…”

“…However, excessive use of an inaccessible mouse lure could lead to predator demotivation for mouse-lure traps (Price and Banks 2012). The extent of effectiveness for lure traps can inform how olfactory stimuli are distributed in time and space (Latham et al 2019). On Guam this could include the deployment of traps, but also the distribution of bird odours (e.g.…”

“…This finding is important because it provides a complementary approach to fox management beyond the traditional approach of lethal removal of foxes from the landscape. It may also be applied to other olfactory-led predator species, with recent experimental evidence demonstrating the effectiveness of an olfactory pre-exposure to protect shorebird populations from a range of olfactory mammalian predators in New Zealand (Latham et al, 2019;Norbury et al, 2021;Price et al, 2020). By conditioning the fox to ignore the odors of a prey species, this tactic targets the predator behavior at the point of prey detection, before an encounter occurs (Endler, 1991;Price & Banks, 2012).…”
