Who Really Dominates a Cockatiel Flock? What Seibert and Crowell-Davis's Study Shows
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
In a cockatiel flock, the assumption that males always dominate females doesn't hold up under direct observation of behaviour. General guidelines on this species are in our article on budgie or cockatiel as a first bird; here is what a landmark study established about this species' social hierarchy.

What Seibert and Crowell-Davis's study shows
A study by Lynne Seibert and Sharon Crowell-Davis, published in 2001 in Applied Animal Behaviour Science, observed a flock of captive adult cockatiels and found that a bird's sex did not directly predict its dominance rank: some females held dominant positions, just as some males did, with no uniform hierarchical pattern tied to sex. The study did, however, document affiliative behaviours, such as mutual preening, occurring more often between certain individuals regardless of sex.
An individual hierarchy rather than a sex-based rule
This result is a reminder to look at each cockatiel as an individual with its own temperament rather than applying a blanket sex-based rule to predict its behaviour in a flock. That's a useful nuance to know before putting together a group, alongside the guidance in our article on choosing between a budgie and a cockatiel for a first bird.
What this means for cohabitation
Building a cockatiel flock means watching the actual individual interactions rather than assuming a male will automatically dominate the group's females. Guidance on setting up shared space is in our bird bedding and habitat section, with enough perches to limit conflict.
- No sex-based rule: dominance rank in cockatiels does not systematically depend on the bird's sex.
- Individual hierarchy: some females dominate males, and vice versa, depending on each bird's own temperament.
- Affiliative behaviours observed: mutual preening concentrates between certain individuals regardless of sex.
- Practical application: it's better to watch the group's actual interactions than to assume a sex-based hierarchy.
This study is a reminder that a cockatiel's social life, like that of many gregarious birds, plays out at the level of the individual far more than at the level of biological sex. Full guidelines are in our bird bedding and habitat section.
Frequently asked questions
Should keeping several male cockatiels together be avoided?
Not necessarily: compatibility mainly depends on the birds' individual temperament and available space, not solely on the sex of the individuals housed together.
How can you spot a dominant cockatiel in a flock?
It typically claims the best perches first and gets priority access to food, a behaviour observable regardless of its sex.
Does this result also apply to budgerigars?
Social hierarchy was studied specifically in cockatiels in this work; comparable mechanisms exist in other gregarious species, but each species deserves its own data.
