July 2020
Sat 18Major Mitchell's Cockatoo
Lawn opposite 134 Grey Street, Kalbarri WA 6536
Photographs taken. Originally observed foraging with a flock, consisting of a number of Galahs and one Little Corella. Later observed with the same flock at the same location (this bird stayed with the flock in the same location for at least 1 hour). When the same flock (same number of Galahs with one Little Corella) was observed the next morning, the Major Mitchell's Cockatoo was not present. The Major Mitchell's Cockatoo has not been observed since. The aforementioned flock was again observed four days later at a nearby location (the Kalbarri Golf Course). The Major Mitchell's was not present at this time either. There are two possibilities of the origin of this bird: 1) The bird is wild, and stayed with the flock of Galahs and one Little Corella for a short time, for some reason, and left that flock to move on (thus it was not observed again) 2) The bird is an aviary escapee, and returned home/was found (thus it was not observed again) Something that is important to note is that there is a parrot park (Rainbow Jungle) in Kalbarri, and one of the species that they have there is the Major Mitchell's Cockatoo (as advertised on one of their posters/brochures/advertising material). However, as shown in numerous Australian Field Guides (including the Australian Bird Guide), Kalbarri is on the edge of the Major Mitchell's Cockatoo's range. It is in the wrong habitat type for it to be observed foraging on a lawn in a town, however it is possible that it is a wild bird. It is difficult to be certain. In WABN 176 (Western Australian Unusual Bird Sightings), this sighting of the Major Mitchell's Cockatoo was noted as follows: Major Mitchell's Cockatoo (1, origin uncertain).
