Pathways and IntroductionEdit

The budgerigar is extremely popular as a pet and as a result has been sold in many countires.[3/4]

Budgerigars have been present in Florida since at least the 1940s, when they were first seen in the city of Saint Petersburg.[5]

Budgerigars were first brought to Great Britain in 1840. It is likely that escaped or hitchhiking animals travelled on ships from Australia to the UK, although the first sightings in the wild were not until 1970 in Tresco.[4]


Budgerigars may compete with native birds for nest sites in some areas and could be carriers of chlamydiosis, also called parrot fever. [2]

Control and Removal MethodsEdit

No methods of controlling or removing introduced populations of budgerigars have been made.[3/4]
