medium-sized parrots which can produce large clutches (four is not uncommon), and our
Rosella box is designed to accomodate a large clutch.
Rosellas will sometimes use the smaller Lorikeet box, but most can spend weeks
inspecting one without ever using it. For those rosellas that do use the smaller box,
mortality of chicks can be high.
Rosellas are not aggressive birds and tend to lose out when
conflict occurs. Lorikeets in particular will take over a box from rosellas, especially if
it is near other parrot breeding sites.
means that boxes for rosellas are best placed on their own, away from other parrot
breeding sites. Isolated boxes in parks and reserves are often difficult to support
because of the effort in monitoring for usage by pests. It may even come to pass that, in
some localities, most rosellas will end up breeding in backyard nestboxes. Thankfully,
rosellas are one of the easiest birds to attract to a backyard box.
The breeding season extends from September to January, and they may make
several attempts during a season.
Rosellas are secretive during breeding. When she is sitting the male will sometimes
visit only a few times during the day. He whistles her out of the box and they fly away
some distance to where he will feed her. Towards the end of the breeding period the young
will sometimes come to the entrance and wait for food.
Refer also our belief that rosellas can smell
and that this could explain why rosellas will not breed in some boxes.
sketch shows the dimensions which we have found to be most suitable for rosellas.
These are probably the best, general-purpose dimensions for a nestbox, having been used
by rosellas, cockatiels, lorikeets, boobook owls, dollar birds and brushtail and ringtail
for information on prices.
