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 »

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 »

“Superb” indeed!  I was captivated by fruit doves early in my career.  The Bronx Zoo’s director at the time was a confirmed “bird man”, and consequently I was surrounded by an amazing collection.  But even among a dozen brilliantly-colored relatives, the Superb Fruit Dove, Ptilinopus supurbus, stood out.  Its intensely green, orange and purple plumage rivals that of any parrot…and while no dove will talk to you, neither will their quiet, pleasant calls jangle your nerves!

Natural History

Over 100 species of fruit doves and pigeons have been described, approximately 60 of which are classified within the Superb Fruit Dove’s genus.

Superb Fruit Doves are found from the Philippines south through Sulawesi and the Celebes to New Guinea and the eastern coast of Australia.  Their preferred habitats include rainforest edges and clearings, mangrove swamps and wooded riversides. Read More »

The gorgeous Plum-Headed Parakeet, Psittacula cyanocephala, combines “exotic” beauty with extreme hardiness.  Active and inquisitive, yet possessed of a calm disposition, this South Asian native makes a wonderful pet or aviary addition.

Description

A slender tail comprises over two-thirds of the Plum-Headed Parakeet’s 14 inch length.  The male’s colorful head, which is clad in mixed shades of red, purple, maroon, violet, rose and/or pink, lends the species its common name.  Females lack the black neck ring and have an attractive bluish-gray head.  The body plumage of both sexes is a beautiful blend of lime and other shades of green.

Albino, green, blue and lutino mutations have been produced by hobbyists.

Range

The Plum-Headed Parakeet ranges from western Pakistan through most of India to Sri Lankain the south and Nepal and Bhutan in the north.  Read More »

A pair of highly endangered Forest Red-Tailed Black Cockatoos, Calyptorhynchus banksii naso, has hatched a chick in an artificial nest box located in Perth, Australia.  The box was erected as part of a conservation effort launched by the Western Australian Museum and Murdoch University.  The nesting is significant because it represents both the first time this species has accepted an artificial nest and the first known breeding in an urban setting.

Unique Threats and Considerations

The Forest Red-Tailed Black Cockatoo faces “typical” problems such as habitat loss, but is also plagued by several unique threats and an unusual breeding biology…all of which complicated the formation of a recovery plan.

Black Cockatoos have very specific nest-site requirements, and once a suitable nesting hollow is located a pair generally uses it for many years.  Over the past several decades, Black Cockatoos in natural habitats have come under pressure from burgeoning populations of feral honeybees and of other cockatoo species, including Galahs and Corellas.  These aggressive insects and birds take over Black Cockatoo nests and severely impact the species’ ability to reproduce.
