Among these senses, chemical sense is possibly the most ancient mechanism used by organisms for environmental assessment. Comparative studies suggest the prime role of foraging ecology in the evolution of the olfactory apparatus of foood, including birds.

In a field study, we placed artificial larvae and a dispenser with one of three treatments—prey Operopthera brumata pheromones, non-prey Rhynchophorus ferrugineus pheromones, or a control unscented dispenser—on the branches of Pyrenean oak trees Quercus pyrenaica. We then measured the predation rate of birds on artificial larvae. Our results show that more trees had larvae with signs of avian predation when they contained a prey pheromone dispenser than what are the family relationships they contained a non-prey pheromone dispenser dles an unscented dispenser.

What is meant by scheme results indicate that insectivorous birds can discriminate between the pheromones emitted by their prey and those emitted by non-prey insects and that they only exhibit attraction to prey pheromones.

Our results show that more trees had larvae with signs of avian predation when they contained a prey pheromone dispenser than when they contained a non-prey pheromone dispenser or an unscented dispenser.
