In a preliminary study (Lupu et al, unpublished data, June 2007), budgerigars
illuminated by 4 full-spectrum fluorescent bulbs (Vitalite F40T12, Duro-Corporation) for 12 hours daily at a 75-cm distance displayed photophobia and stress-related disease, while experiencing no significant increase in 25-OH-D after 11 weeks.
Samples from some of the affected budgerigars
that died were subsequently reviewed at another laboratory.
In studies with budgerigars
(5) and zebra and Bengalese finches, (6) all external vasectomies were performed with a 10x operating microscope.
The national Budgerigar
Society has advised its members to cancel shows and stop trading birds - meaning that dozens of events across the North have had to be called off for the next four months.
11,13,15) Asymptomatic juvenile and young adult budgerigars
are suggested as being responsible for transmission of the virus, through droppings and skin and feather dander, to neonatal birds, which are at a substantially higher risk of fatal disease.
Effective medical management of these conditions is often mandatory in small birds, such as budgerigars
The flock consisted mainly of parakeets belonging to the Neophema group (Neophema splendida, Neophema pulchella), but also included 25 budgerigars
(Melopsittacus undulatus), 4 pairs of Bourke's parrots (Neopsephotus bourkii), 3 pairs of red-crowned parakeets, and 2 pairs of parrotlets (Forpus species).
, as a general rule, disease is confined to nestlings, which develop a peracute or acute form, with high mortality.
The 5 budgerigars
used as biologic sentinels died within an average of 5 days after being placed in the enclosures.
Neoplasms in budgerigars
(Melopsittacus undulatus): clinical, pathomorphological and serological findings with special considerations of kidney tumors.
5) A list of plants reported to be toxic specifically to budgerigars
includes avocado (Persea americana), black locust (Robina pseudoacacia), clematis (Montana rubens), lily-of-the-valley (Convallaria majalis), oleander (Nerium oleander), philodendron (Philodendron scandens), poinsettia (Euphorbia pulcherrima), Virginia creeper (Parthenocissus quinquefolia), and yew (Taxus media).
The Blank Park Zoo began suffering mortalities in the spring of 2012 within a flock of 229 captive budgerigars
(Melopsittacus undulatus) housed in an interactive public-feeding aviary.
