Whether they are hand or parent-reared, young Canaries usually need some encouragement to switch from the nestling to adult diet.  This change-over period can be quite stressful, but there are a number of steps you can take to ease the transition.

The Transition Period

Pet Canaries feed their chicks largely upon sprouts, soaked seeds and Egg Food or hard boiled eggs.  Once the young fledge, which usually occurs at age 16-20 days, they will be fed by their parents for an additional 2 -3 weeks.  During this time, they will also begin to pick at food and eventually learn to eat on their own.  Fledglings benefit from watching their parents and siblings…chicks that are hand-reared are at a disadvantage in this respect, but will also respond to the ideas and foods mentioned below.

Hard seeds are a novel food for young Canaries, and acquiring the skill needed to open them takes practice.  A high protein diet remains important right through the first molt (which usually begins within 2 months of fledging), but eventually seeds should replace egg-based foods as their staple.  Read More »

In times of economic distress, government-funded wildlife conservation often takes a back seat to competing concerns.  InAustralia, private (non-governmental) groups are taking up some of the slack…and doing a fine job.  Over 6,000,000 acres of land are now being privately managed for the benefit of native animals and plants.

Wildlife in Peril

Parrot conservation often takes center stage when talk turns to Australian wildlife, but a wide variety of other animals are also in trouble.  A recent report (please see below) states that 27 species of Australian birds are now extinct, 20 are critically endangered, 68 are vulnerable and 63 are classified as near-threatened. Australia leads the world mammal extinctions, and severe declines have also been noted among reptiles, amphibians and fishes.

The Eclectus Parrot is well known for an unusual degree of sexual dimorphism (males are emerald green, females bright red) and a breeding strategy wherein several males mate with a single female.  But no one expected the results of a recent study: under certain circumstances, mothers will kill their male chicks and raise only females.  Other than humans, Eclectus Parrots are the only species known to kill offspring based solely upon gender.

Harsh Conditions and Drastic Adaptations

The study, published in the journal Current Biology (October, 2011), was conducted by researchers based at the Australian National University.  The study site was at Cape York, Queensland, in Australia’s tropical northeast (Eclectus Parrots are also found on New Guinea and many Indonesian islands).  Read More »

Also known as Psittacine Circovirus Disease, PBFD, which is incurable, has been identified in over 60 species of wild and captive parrots. It has been much in the news lately, and the questions I’ve received indicate that some of the coverage has been confusing to bird owners. Today I’d like to summarize what we know, and what remains to be done in the battle against PBFD.

PBFD Natural History

The virus that causes PBFD was first described in 1987, when it was discovered in a captive group Orange-Bellied Parrots, a highly endangered species.  Further study revealed that the virus occurred naturally in Australia, and likely was endemic there (found nowhere else). The disease is now established worldwide, apparently having been spread by the legal and illegal trade in parrots.

The PBFD virus is an extremely hardy organism, and likely survives for many years in nest hollows and roosting/feeding areas. To date, only one disinfectant, Virkon S, has proven able to kill it.  The virus has been found in feather dust, feces and the crop lining of infected birds.  Transmission seems to occur in several ways – direct contact with sick birds, inhalation of the virus from dust and feces and via food passed to chicks by parents.

Also known as Tri-Colored and Black-Headed Nuns or Mannikins (Lonchura Malacca and L. atricapilla), these pert little birds make excellent pets for both beginning and advanced finch keepers.  While neither sports the flashy colors of certain related species, contrasting black, chestnut and white plumage renders them quite striking.

Natural History

The 5-inch-long Tri-Colored Munia is found in southern India and Sri Lanka.  It is most common in and near swamps, flooded meadows, riversides, rice fields and other moist, open habitats.

The Black-Headed Munia was long considered to be a subspecies of the Tri-Colored, but has now been designated as a distinct species.  However, captives interbreed readily, and will also pair up with related finches. Its natural range, which lies north and east-southeast of the Tri-Color’s, extends from northern India through southern China, Thailand and Vietnam.  It tops out at 4.5 inches in length. Read More »
