EEP STUDBOOK CROWNED PIGEONS
Results of the observational research project
Comparison between enclosures
As described before, there are large differences in size and furnishing of the enclosures for
crowned pigeons in the Dutch zoos. This may influence the time budgets of the crowned
pigeons.
Significant differences between the enclosures within the category “space” were found (F(6,9)
= 5.45, P = 0.0122). Especially in one of the cages in Amsterdam Zoo, the enclosure with
Goura cristata in Alphen a/d Rijn birdpark and the birds in Burgers’ Breeding Area spent,
according to Duncan’s Multiple Range Test, more time conducting behaviour in space, than
the birds in the other enclosures.
No significant differences between the enclosures for behaviour in time and sexual, care and
metabolic behaviour could be found The birds in Burgers’ Breeding Area spent, according to
Duncan, significantly (F(6,9) = 6.14; P = 0.0083) more time showing positive social
behaviour. On the contrary, the crowned pigeons in Burgers’ Bush showed significantly
(F(6,9) = 4.01; P = 0.0311) more social negative behaviour in comparison with the other
birds.
