African Grey Parrot

Category: Birds
Phylum: Chordata
Class: Aves
Order: Psittaciformes
Family: Psittacidae
Species: Psittacus erithacus


These amazing birds are extremely intelligent due to their ability to mimic human voices and other sounds. In recent studies, African Grey Parrots have proven to have one of the highest vocabularies of the entire bird species.


The African Grey Parrot resides in West and Central Africa. The females are usually a lighter shade of gray with a slightly dimmer red tail, whereas the males are a deeper gray, with a more vibrant red tail. Though not as colorful as some of its relatives, African grey parrots are a favorite because of their amazing personalities.

As with all pets, if you are interested in obtaining an African Grey Parrot, we strongly recommend that you thoroughly check it out ahead of time. These wonderful creatures require a tremendous commitment. They can be great pets, but do require a lot of work and a lot of love!

Accentor

Category: Birds
Phylum: Chordata
Class: Aves
Order: Passeriformes
Family: Prunellidae
Species: Prunella

Accentors are small, sparrowlike birds founds throughout Europe and Asia. Unline Sparrows, they have slender, finely pointed bills and are more closely related to Thrushes or Warblers.

Accentors usually live in mountainous regions, often well above the tree line. The Alpine Accentor is no exception, one race breeding at altitudes of up to 18,000 ft. (5,500 m). However, most Accentors breed at lower levels, in scrub-type vegetation. The Dunnock is particularly common in woods, hedgerows and gardens. In summer, Accentors feed on insects; in winter, they live almost entirely on seeds and berries.

Tree frogs

Nature has provided some crafty little defense mechanisms for amphibians to protect themselves against predators. While amphibians may not have special weapons like claws or sharp teeth to defend themselves, they do have slippery, quick moving bodies and a very shy, quiet nature. This may not seem like much of a defense, but don't be fooled. These are beautiful, resiliant creatures that have survived a very long time on this planet

As another form of protection, many amphibians don't show themselves in the light of day. They also have other survival tricks involving an attribute known as Coloration. There are several types:
Flash Coloration
Warning Coloration
Protective Coloration

Flash Coloration is different from Warning Coloration, because it is not seen until the amphibian is under attack. Their bright colors often times distract and confuse predators, thus help the amphibians escape. Changing skin coloration is employed by frogs, toads, and some salamanders.

Predators who attack a brightly colored amphibian quickly learn to avoid similar-looking ones in the future. Protective Coloration is important to many amphibians, a large number of which are green, brown, or gray colors that are common in nature. These color patterns act as camouflage, helping amphibians blend in with their surroundings

Treefrogs and other color-change artists change their colors over time to match the background they rest upon. Some amphibians produce mild skin poisons, and others produce toxic secretions strong enough to kill predators, like the Poison-arrow frog.
