Olfactory eavesdropping: The odor of feathers is detectable to mammalian predators and competitors

Abstract: The role of olfactory eavesdropping in interactions between mammalian predator and prey species is well established. Bird plumage can be odorous and consequently nest predators could use odor to identify and locate avian prey, and nest competitors could use odor to assess occupancy of nest cavities by birds. However, despite extensive research on avian nest predation and competition, the costs of olfactory eavesdropping on plumage odor by nest predators or competitors remain largely unknown. We used two experi… Show more

“…Petit et al () deposited experimental faeces that predators could visualize near focal artificial nests and attracted predators. Rubio et al () performed a similar experiment in inactive nests of a grown nester, but in this case, the presence of faecal sacs did not attract predators. Moreover, Ibáñez‐Álamo et al (b) hided experimental faecal sacs to terrestrial predators in common blackbird Turdus merula active nests, which did not increase the probability of nest predation, suggesting that Petit et al ()'s results were due to visual cues of faecal sacs.…”

“…Recently, the importance of volatiles produced by symbiotic bacteria have been stressed in scenarios of social communication (Theis et al , Ezenwa and Williams , Leclaire et al ), predator–prey, or parasite–host interactions (Bucher , Gow et al , Schulte et al ). Prey might for instance use predator odours in antipredator behaviour (Heise‐Pavlov ), or predators might use volatiles from symbiotic bacteria of prey as clues to detect their victims (Fogarty et al , Mihailova et al ). Previous studies have explored the possibility that faecal sacs attract potential predators and/or parasites, but did not find support for the hypothesis.…”

“…nocturnal predators are more likely to use olfactory (Mihailova, Berg, Buchanan, & Bennett, 2018;Whelan, Dilge, Robson, Hallyn, & Dilge, 1994), thermal (Stake, Thompson, Faaborg, & Burhans, 2005;Weatherhead & Blouin-Demers, 2004) and auditory cues (Briskie, Martin, & Martin, 1999;Halupka, 1998;Rice, 1982) to find nests.…”
