In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. [1] The order passerines (perching birds) alone accounts for well over 5,000 species.
Birds have one of the most complex respiratory systems of all animal groups. [79] Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs.
The woodcreepers are generally forest birds of Central and South America. Most species occur in rainforests, with the centre of diversity of the subfamily being the Amazon Basin .
