What’s for breakfast!
A local volunteer caring for outdoor cats found this new face at the feeding station one morning.
Baylisascaris procyonis is a roundworm (similar to those commonly found in dogs and cats) carried by many raccoons. In the small intestine of the raccoon, this roundworm may be little more than a nuisance. The eggs are spread by raccoon dung.
Baylisascaris also infests a wide range of birds and mammals – including people. When Baylisascaris finds itself in animals other than raccoons, it bores through the intestinal tract, attacking the liver, lungs, eyes and brain.
Raccoon roundworms can be a death sentence for pigeons, doves, parrots, chickens and other birds.
In humans, detection is often difficult and too often too late. Debilitating illness, blindness, permanent afflictions and death can result. And the cases of disease discovered by doctors quite likely are far from the total number of infections. People are big so a small number of roundworms tunneling through tissue may only cause non-specific symptoms. (The eye is an exception. If only one of the parasites gets there, serious damage results.) This is far from good news. Even if the parasite fails to send a victim to an emergency room or a morgue, there’s no such thing as an acceptable number of worms eating away at the brain or other organs.
The raccoon long was an icon of the deep forest and only was expected to be found there. Indeed, the coonskin cap is associated with Davy Crockett and other frontiersman. When raccoons just inhabited rural areas, city dwellers had no reason to worry about Baylisascaris. This now is the strange new One World that has such diseases in it. Like viruses of the African rain forest that have made their way to New York, parasites of the back woods now can be found here. Raccoons — and their roundworms — reside in Manhattan, the other Boroughs and throughout the Metropolitan area.
A specific risk to public health is the increasingly common – and publicly promoted – caring for outdoor cats, if not responsibly done. Large quantities of food placed out at night or before dawn will surely attract raccoons. Regularly eating somewhere, raccoons will be regularly relieving themselves nearby and so posing a danger to people. As raccoons are secretive and only active after dark, most people will never see them. Once the animal excrement becomes part of the soil, that hides the roundworm eggs. People – especially children – then can be easily infected.
The answer is not the elimination of cats or the persecution of raccoons, but common sense. Feed community cats after sunrise and well before sunset. Only put out as much as the felines will consume, not leaving any extra for “guests.” Raccoons are native animals and so they are our neighbors. These furry fellows with the bandit mask have every right to live their lives in peace.

At French’s Bird Institute, Ted F. Ey shows what a man would have to eat each day if he had the proverbial “appetite of a bird.” Birds eat nearly 100 times their own weight in food in a year. The average man eats less than 10 times his own weight annually.
SHOWN HERE, literally eating like a bird, is Ted F. Ey of Rochester, New York.
A study of parakeet eating habits has exploded the popular idea that birds have tiny appetites. Instead, it showed that the average parakeet eats nearly 100 times its own weight annually in seed, cuttlebone, gravel and water. Because the parakeet weighs only about 1 1/4 ounces, this actually means that it consumes about 8 pounds of food a year. To eat at the same rate, a man would have to devour some 16,000 pounds of food annually instead of his normal consumption of 1,300 pounds.
With his pet parakeet, “Frenchy,” watching from his shoulder, Ey is shown breakfasting on wheat cakes, with the rest of his day’s “bird rations” before him-45 pounds of meat, poultry, potatoes, vegetables, fruits, eggs, milk and other foods!

Supreme Birds is eager to hear from breeders of american parakeets, canaries, cockatiels, finches and lovebirds. We are also very interested in contacting manufacturers of pet products seeking representation in the United States, particularly the New York City metro area. Please email email@example.com
Supreme Birds is run by Anthony Olszewski. Mr. Olszewski has published many articles on cage birds in avicultural journals in the United States, Great Britain and other countries. He authored a chapter on avian genetics for a veterinary text book and worked as an editor at a magazine produced by TFH, the world’s largest publisher of pet books. Anthony Olszewski also has written for major tropical fish journals about Lake Malawi African Cichlids and Discus. He managed a retail pet shop and ran a wholesale bird seed business.
Anthony Olszewski offers consulting services for the maintenance, breeding, and research of cage birds (particularly budgerigars, canaries, and zebra finches) to manufacturers, educational institutions and government.
Handbook of Avian Hybrids of the World
EUGENE M. McCARTHY
Handbook of Avian Hybrids of the World attempts to list all avian crosses reported in the scientific literature and/or on the Internet (the vast majority of the documentation is of the former type). Quite a few personal communications are also
included. It is the broadest survey of its kind to date, listing not only crosses occurring under natural conditions, but also those obtained in captivity. No general reference on this subject has been published in English since 1958 (A. P. Gray’s Bird Hybrids). Since that time, interest in avian hybridization has been steadily rising, especially with regard to the fields of taxonomy, conservation, and evolutionary biology. In recent years, reports of hybrids have been far more frequent than in the past (Randler 1998). The increase is probably due to a large rise in the number of field observers, better optical equipment, and an enhanced awareness of the existence of avian hybrids. Unusual hybrids are now often prominently featured in birding magazines and are puzzled over by birders in chat rooms on the Internet.
Gray’s book continues to be cited, but mostly for lack of anything more up-to-date. There has been a need for a new reference that takes into account the last half century of data. Moreover, although often cited by academics, Gray’s book has a decidedly utilitarian perspective, slanted toward the concerns of the breeder rather than the professional biologist. A more recent work on the topic, written for biologists rather than breeders, is E. N. Panov’s Natural Hybridization and Ethological Isolation in Birds (1989). It is also widely cited, but is still 17 years out of date,
written in Russian, and covers only natural hybrids. Data on hybrids produced in captivity can also be important to naturalists. Crosses produced in aviaries often allow identification of specimens obtained in the wild. This book represents an effort to fill these gaps in the literature.
