Is Yawning Contagious in Budgies, Just Like in Humans?
Watching two budgies in the same cage yawn within seconds of each other is more than a mere curiosity. Life in pairs and its benefits are covered in our article on one budgie or two; here is what science has discovered about this shared behavior.
What research shows about contagious yawning in birds
A study by Gallup and colleagues, published in 2015 in Animal Cognition, exposed budgerigars to videos of flockmates yawning and found a measurable increase in yawning frequency among the observing birds, providing the first experimental evidence of contagious yawning in a non-mammalian species (study on Google Scholar). Until then, this phenomenon had only been demonstrated in humans, some great apes, dogs, and one laboratory rat strain.
A social signal rather than a simple physiological reflex
In humans, contagious yawning is linked to mechanisms of empathy and social synchronization between close individuals. The study's authors propose a similar avenue in budgies, a flock species whose group cohesion relies heavily on shared signals.
What this reveals about a budgie's social needs
This finding reinforces the idea that a solitary budgie, deprived of a flockmate with whom to synchronize this kind of behavior, misses out on an entire dimension of normal social life. The specific risks of solitude are covered in our article on the mirror for a single budgie, a false fix for this need for real companionship.
Should frequent yawning be a concern?
An occasional yawn, alone or in response to a flockmate's, remains normal behavior. Repeated yawning combined with audible breathing or lethargy is an entirely different matter and warrants a vet visit.
- First evidence in a non-mammal: the budgerigar joins humans, some apes, dogs and rats.
- Likely social signal: a synchronization mechanism between flockmates, not just an isolated reflex.
- One more argument for a pair: a budgie's social life extends to these small shared behaviors too.
- Isolated, normal yawning: distinct from abnormal breathing, which does warrant a vet's opinion.
This seemingly trivial behavior shows just how rich and well-studied a budgie's social life remains, one more argument in favor of adopting a pair rather than a single bird. Full guidelines are in our bird toys and enrichment section.
Frequently asked questions
Does contagious yawning exist in other pet bird species?
It has been specifically demonstrated in budgerigars; its presence in other species such as canaries or cockatiels remains to be confirmed by dedicated studies.
Can a budgie yawn in response to a human yawning in front of it?
This exact link wasn't tested by the study, which focused on flockmates; nothing today allows us to confirm it.
Is frequent yawning in a budgie a sign of tiredness, as in humans?
The exact link between yawning and tiredness is less well documented in birds than in humans; an isolated yawn with no other symptom is nothing to worry about.
