Understanding Psittacine Beak and Feather Disease (PBFD)

PFBD Infected CockatooAlso 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.

517 Wild-Caught Amazon and Pionus Parrots Seized in Brazil

Pionus menstruusTheUSA has long prohibited the importation of wild-caught parrots, and many countries regulate the collection of native species.  However, enforcement difficulties and huge profits ensure that the taking of wild parrots continues on a scale that surprises many conservation-minded bird-keepers. Over the last 18 months, the illegal trapping of African Gray Parrots has been very much in the news (please see article below).  Unfortunately, a recent confiscation of Blue-Fronted Amazons, Yellow-Faced Parrots, Blue-Headed Pionus and Scaly-Headed Pionus shows that the problem is not limited to Central Africa.

Trapping and Habitat Loss go Hand-in-Hand

The illegally-collected parrots were hidden beneath cargo in a truck that was stopped in Pernambuco State, Brazil, on September 25, 2011.

Most of the birds appeared to be youngsters, which may indicate that nesting trees were destroyed in the process of collecting them (trappers frequently chop down nesting trees in order to reach young parrots).  Trees containing suitable nesting holes are a rare resource in most habitats, and are important to the survival of a wide variety of birds, invertebrates, amphibians, mammals and reptiles.  Their loss has severe, long term implications.

Helping the Confiscated Parrots

The displaced parrots are being cared for byBrazil’s Environmental Conservation Organization (ECO).  Caretakers have the expertise to rear them, but as you can imagine the cost and time involved, especially where nestlings are concerned, is enormous.  The stress, poor care and cramped conditions endured by the parrots while in collectors’ hands will ensure that many need medical attention.  Read More »

The Natural History and Captive Care of the Superb Fruit Dove

Superb Friut Dove“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 »

Number of Unwanted Parrots Reaches an All-Time High in the USA

Rainbow LorikeetsRecent advances in parrot husbandry and captive breeding may have had an unintended effect.  Lower prices and a larger selection of available species may be contributing to a problem of epic proportions – hundreds of thousands of abandoned parrots, macaws and cockatoos, many of which will never find a permanent home.  While parrot ownership has soared a staggering 147% over the past 20 years, from 11.6 million pets in 1990 to 60 million in 2010, our ability to provide for them has not kept pace.

Desirable but Demanding

The very qualities that draw people to parrots – intelligence, sociability and long lives – also render them as unsuitable pets for the average person.  Many live as long as their owners, who often find it difficult to provide for their pets, financially and otherwise, as time goes on.  According to a study by Best Friends Animal Society, it is not unusual for an elderly parrot to have 7-11 owners over the course of its life.

Parrots are likely the USA’s third most popular pet, yet many people do not realize that, unlike dogs and cats, they are not domesticated animals.  As wild animals, parrots have very different needs than domestic creatures.  Few people are able to provide the space, social situation and emotional environment needed by these active, “complicated” birds.  I have observed many species in the wild, and, despite years of study and zoo experience, was surprised by how much of their time was spent on the move and in direct contact with others.  The noise they produced was deafening…even on wide-open grasslands.

The Natural History and Captive Care of the Plum-Headed Parakeet

Plum-headed ParakeetThe 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 »
