  • BirdLife International's "Chim Vietnam" ("Birds of Vietnam") goes into second printing. It's the first color Vietnamese-language field guide to birds of Vietnam. 3000 copies were printed for the first edition in 2000.
  • Census shows population increase of New Zealand's Takahe (Porphyrio hochstetteri). It was rediscovered in 1948 after being listed as extinct for fifty years. It's still endangered, but gaining ground.
  • US Fish & Wildlife Service seeing success in recovery program to help the Red-cockaded Woodpecker (Picoides borealis). They were declared endangered in 1970. The USFWS launched a program in the 1990s and since 1994, the population has grown 30% to over 6000 birds. Officials say at this growth rate, it will be another 70 years before the bird can be taken off the endangered list.
  • Thousands of bird watchers in India participate in a census of the Great Indian Bustard (Ardeotis nigriceps). The IUCN said last year the bird could be extict within a decade.
  • Blackpoll Warbler (Dendroica striata) added to the Pennsylvania endangered species list. Although fairly common as a migrant, it was added to acknowledge the nesting population.
  • Department of Public Work employees in Hornell, New York rescue juvenile American Kestrel. Its parents left it to fend for itself, but it wasn't quite ready.

  • Colorado state agency unveils plan to help protect the Greater Sage-Grouse (Centrocercus urophasianus). The State Land Board will spend $120,000 over five years to determine population, ways to protect them, and how to enhance sagebrush and other vegetation that's been reduced by drought and other factors.
  • Southern Mississippi birds taking a beating from tropical storms. The Mississippi Coast Audubon Society estimates "we've probably lost half the birds we would normally have during a good season."
  • Trucker finds Red-tailed Hawk hopping on one foot on the side of a road in Pennsylvania. He captured it and alerted authorities, who found the hawk was malnourished. They're trying to find out if it's caused by neurologic damage or the West Nile Virus.
  • Angelina Jolie's African Grey Parrot throws fits when she's away. It stages hunger strikes and attacks customers in the pet store where she houses it.
  • Wisconisn paper mill adopts family of Peregrine Falcons.
  • Laramie, Wyoming residents rescue Swainson's Hawk chick after it's blown out of the nest.
  • San Salvador parrot helps to foil a robbery.

In 1977, Dr. Irene Pepperberg bought Alex, an African Grey Parrot (Psittacus erithacus erithacus), from a pet store in Chicago. She bought Alex because he was an ordinary parrot, but Dr. Pepperberg was no ordinary person; she sought to find out how smart the ordinary African Grey Parrot really was. With no special breeding traits or formal training, Alex was the perfect subject.

Through the years, Dr. Pepperberg found that Alex understood a number of concepts and methods including counting, identifying and lableling objects, wanting something versus identifying something, and telling what's same and what's different. And now, Dr. Pepperberg has made another breakthrough. Recent studies have shown that Alex understands the concept of zero. It may not sound like much, but zero is thought to be an abstract concept that people don't grasp until age three or four. And some ancient cultures as recently as the Middle Ages didn't even have a term for it. It's thought that Alex may have known what zero was, but now knows how to convey it.

"It is doubtful that Alex's achievement, or those of some other animals such as chimps, can be completely trained," Pepperberg said. "Rather, it seems likely that these skills are based on simpler cognitive abilities they need for survival, such as recognition of more versus less."

Dr. Pepperberg's studies have been invaluable. Not only has she given great insight into animal behavior, knowledge, and communication, but her model-rival training techniques are being used for teaching dysfunctional children. For more information about her research and how you can help, please visit The Alex Foundation. Also be sure to check out The Alex Studies: Cognitive and Communicative Abilities of Grey Parrots. It's a fascinating read.
