Avian Respiratory System
AVIAN RESPIRATORY SYSTEM
Birds possess a very unique and efficient respiratory system. They lack a diaphragm, have non-expandable lungs and a system of air sacs that extend into many of their bones. Vocalization is by means of a syrinx, not a larynx as in mammals.
Anatomy
The nostrils or nares are usually located at the base of the beak. In psittacines (parrots) they are located within the area of the cere. Amazons have a structure known as an operculum inside the nare which helps prevent inhalation of foreign bodies. In most birds, the nares are readily visible, while in certain birds-such as crows-they are covered by feathers.

What Is Wrought Iron? Why Are Bird Cages Made From It?
 From Wikipedia, the free encyclopedia.
Wrought iron is a very pure form of commercial iron, having a very small carbon content. It is tough, malleable, ductile and can be easily welded. However, it is too soft to make blades and swords. When formed into bars, it is known as “bar iron”. Wrought iron has been used for thousands of years, and represents the “iron” that is referred to throughout history.

A Conversation with Greg Glendell, UK Parrot Behaviorist: Part Two — Screaming
A few weeks ago we began our three part series about a telephone conversation I had with noted UK parrot behaviorist and author, Greg Glendell. Because we talked for about two hours, I found it best to break the highlights of our conversation into the three main topics: biting, screaming and plucking. Part One of the series covered biting. Today I’d like to summarize some of our discussion on parrot screaming.

Total Cockatiel Personality Change After Death of Cage Mate – What Can Be Done?
“Poor Popcorn”, it seems we say that a lot. She has such high expectations of us and when we cannot fulfill them for her, she lets us know, but unfortunately we can’t explain “why” in bird speak.
Since we have had her, she has gotten us well trained to serve her, she wants attention when she wants it and not most other times. BUT she does want people time every day.
