That Bird Blog – Bird Care and History for Pet Birds

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.

Sending flowers is a time-honored way of showing affection and concern, but did you know that your parrots and other feathered pets might appreciate a bouquet as well?  I’m not suggesting actually having flowers delivered to your parrot (although I know several who have done that!), but rather that you consider edible flowers as a source of bird food and behavioral enrichment.

The Role of Flowers in Bird Diets

Flowers, buds and nectar figure heavily in the natural diets of many parrots, finches and softbills.  In fact, lories and lorikeets are actually “floral specialists” (please see drawing of lorikeet tongue, adapted for nectar feeding).  However, with the exception of nectar-mixes, flowers have largely been ignored by most pet keepers.

Flowers are also a major food item of several less commonly-kept softbills, including hummingbirds, sunbirds and the aptly-named flower-peckers. Ornithologists speculate that the brilliant colors of some species may have evolved to provide camouflage during feeding sessions in flowering trees.

Behavioral Stimulation

In addition to their nutritional value, flowers can provide important behavioral stimulation for parrots and other birds.  Most parrots delight in tearing them to bits, and bud-covered fruit tree branches (apple, pear, plum etc.) will provide hours of entertainment for both pet and pet-owner.  Finches, White-Eyes, Pekin Robins and other small birds will also poke about in flowers for insect treats, real or “imagined”, and may consume petals and nectar as well.

Purchasing Flowers

Fortunately, it’s quite simple to incorporate flowers into your birds’ diets.  Many bird-safe flowers are relished by people, and are available in food stores.  In NYC markets, I’ve come across squash, zucchini, rose and daylily flowers (note: not all daylilies are safe for people or birds, so do not pick your own), as well as a number that I did not recognize.  Korean, Chinese and Indian neighborhoods have proven especially rich flower-hunting grounds.

Do not buy edible flowers from garden supply outlets or florists, as these will not have been slated for human consumption and would likely have been exposed to toxic chemicals.

Dried flowers specifically marketed as bird food are also a useful option.  Goldenfeast’s Hibiscus and Chamomile

may be offered to a variety of parrots, finches and softbills.

Growing and Collecting Flowers for Your Birds

If the option is available to you, growing your own edible flowers is a great alternative to shopping.

Harvesting wild flowers is also possible, but you must be confident in your ability to identify the various species and have access to a pesticide-free collecting site.  A field guide will be useful in this regard.

Common, Easy-to-Grow Edible Flowers

The following common flowers are readily accepted by many birds and can easily be grown or, in some cases, purchased at food markets.  Do not buy flowers intended as food anywhere other than at a food market; please see above.

 

Daisy                                                   Marigold

Dandelion                                           Rose

Carnation                                            Sunflower

In a recent article, I suggested some techniques that can be used to keep your birds cool and safe during hot weather (please see article below).  Today I’d like to take a look at recognizing and dealing with heat stress and heat stoke.

Note: the attached photos depict some North American birds that are well-adapted to desert habitats – the Roadrunner, Gila Woodpecker and Elf Owl.

Dangerous Places and Temperatures

Wild birds and pets kept in large outdoor aviaries rarely experience heat-related problems, no matter how high temperatures climb (of course there are limits – don’t try keeping your pet penguin outdoors in Las Vegas!). Read More »

Most parrots, finches and other pet birds are native to tropical habitats, but summer weather can still be a threat to their health.  Wild birds have numerous ways to regulate their exposure to extreme temperatures, but caged pets must rely upon us to take action on their behalf.

Heat Metabolism in Birds

A basic understanding of avian heat metabolism will help you to evaluate the risks presented by the local weather conditions.  Birds maintain higher internal temperatures than do people – 105 F for most species, and up to 108 F in some.  So, if you are uncomfortable with the temperature, your bird will likely will be so as well.  Read More »

When I first began working with birds in zoo collections, older keepers warned me about respiratory ailments such as “Bird Breeder’s Lung” and “Poultry Worker’s Disease”.  Several of my co-workers were always short of breath and coughed frequently.  Eventually, some were diagnosed with Hypersensitivity Pneumonitis (a/k/a Extrinsic Allergic Alveolitis), which results from inhaling organic dust and other irritating substances.  Private bird owners are also sometimes afflicted with this condition, and birds themselves may sicken and die when exposed to certain common airborne particles and chemicals.  Unfortunately, advertisements for air-cleaning devices have confused rather than clarified the options available to us; some are actually harmful (yet still on the market!) while others are highly effective.
