Fossil Allows Researchers to Distinguish Sex of Ancient Bird-Like Creature

Reconstructed profiles of three tapejarine pterosaursPterosaurs (incorrectly labeled “Pterodactyls” by old-timers such as I) flew the skies during the Mesozoic Era, some 220-65 million years ago. The huge head crests sported by many have baffled scientists since the first specimen was found in 1784 (please see drawing). However, a recently discovered fossil hints that sexual dimorphism may be involved, and has allowed researchers to determine the sex of fossilized Pterosaurs for the first time.

Technically, Pterosaurs are flying reptiles, not birds. Yet they possess many bird-like qualities, so I thought that bird enthusiasts might be interested in this latest finding concerning their lives. In any event, taxonomy is constantly blurring the lines between various groups (for example, birds are now considered to be “modern dinosaurs”, and closely related to crocodilians), so perhaps Pterosaur classification may change in the future… Read More »

Teaching a Parakeet to Perform Tricks – Target and Clicker Training

The Parakeet, Budgerigar or “Budgie”, Melopsittacus undulatus, arrived on the European pet scene in 1840 and has since become one of the world’s most popular pets. However, perhaps because they are small and inexpensive, Budgies are sometimes not viewed as “real parrots” by their owners, and consequently are not given the chance to show off their many talents. In addition to being wonderful mimics, Budgies can learn a great variety of tricks…and seem to take pleasure in doing so!

Trust

Getting your pet to accept your presence, and then to be comfortable with your hand in its vicinity, is an essential first step in training. This is generally quite simple, as budgies are sociable by nature and rather miserable without human or avian company.  Please see this article for more on basic care and creating trust.

The Natural History and Captive Care of the Gold-Breasted or Zebra Waxbill

Philippine cockatooThe Zebra Waxbill, Amadava subflava (also known as the Gold or Orange-Breasted Waxbill), is one of the tiniest of all African birds available to aviculturists.  With their bright yellow bellies and brilliant red rumps, the males are a sight to behold.  A mere 3 to 3.5 inches in length, they are a delight to keep and breed, and quite hardy as well.

Natural History

The Zebra Finch is found throughout much of sub-SaharanAfrica.  It favors grasslands and lightly-wooded savannas (please see photo), but has adapted to farms and village outskirts as well.  Grass-seeds and insects comprise the bulk of its diet.

A larger and more colorful subspecies, Clarke’s Waxbill, Amadava subflava clarkii, occupies the southern portion of the range.  Unfortunately, it is not common in private or public collections. Read More »

Parrot Conservation – USA Protects 3 Cockatoos under the Endangered Species Act

Cockatoo in treeThe US Fish and Wildlife Service has taken action on a proposal originally filed by Friends of Animals in 2008.  Three of the affected species are popular in the pet trade – the Umbrella or White Cockatoo (Cacatua alba), the Sulphur-Crested Cockatoo (C. sulphurea) and the Red-Vented or Philippine Cockatoo (C. haematuropygia).  The Crimson Shining Parrot (Prosopeia splendens) was denied Endangered Species Act (ESA) protection.

ESA Protection Denied for 8 Parrot Species

The original application filed by Friends of Animals sought ESA protection for 8 additional species, including the Military, Scarlet, Blue-Headed, Great Green and Hyacinth Macaws, the Yellow-Billed and Red-Crowned Parrots and the Grey-Cheeked Parakeet.  Of these, only the 3 cockatoos listed above and the Crimson Shining Parrot were selected by the US Fish and Wildlife Service as warranting further consideration.

Small Cockatoos with Big Personalities – Introducing the Corellas

Long-billed CorellaCockatoos are often considered to be the most intelligent, playful and trainable of all parrots.  But most new parrot-keepers believe that all cockatoos are large, noisy and very expensive, and tend to pass them by.  While this applies to many of the world’s 40+ species, one group – the Corellas – averages only 12-15 inches in length; among the cockatoos, only the Cockatiel is smaller.  Corellas possess all the wonderful traits of their larger relatives, and few of the drawbacks.  In fact, the Goffin’s Cockatoo or Tanimbar Corella may just be the best cockatoo pet for most people.

Corella Overview

Despite their small size, Corellas demand a great deal of attention and space, and cannot be relegated to life in a cage.  Successful owners usually find that they become more like dogs than birds in their interactions with people.  Well-habituated cockatoos of all kinds love physical play and touching, often to an amazing degree.  They also tend to be unsurpassed when it comes to learning tricks.  Read More »
