Falcons can use olfaction to detect food in a test setting

Area of Science:

• Ornithology
• Sensory Biology
• Animal Behavior

Background:

• Historically, raptors, including falcons, were believed to have minimal or no olfactory sense.
• This perception has limited understanding of avian sensory capabilities.

Purpose of the Study:

• To investigate the olfactory capabilities of peregrine falcons (Falco peregrinus peregrinus) and their hybrids.
• To determine if falcons utilize their sense of smell for detecting food.

Main Methods:

• A controlled experiment was designed to test the ability of falcons to detect food using olfaction.
• The study involved peregrine falcons and peregrine falcon/gyrfalcon hybrids (F. peregrinus×rusticolus).

Main Results:

• All tested birds demonstrated the ability to detect food using their sense of smell.
• The experiment provided empirical evidence of olfactory function in these raptors.

Conclusions:

• The findings support the growing evidence that birds, specifically falcons, possess and actively use an olfactory sense.
• This research contributes to a revised understanding of avian sensory perception.
