What reading level is Birds: the Elements of Ornithology book?
To quickly assess the difficulty of the text, read a short excerpt:
The wary, or essential female organ, is generally single ; its companion aborting. It is usually the right ovary which atro- phies. This female organ has somewhat the appearance of a small bunch of grapes, the grape-like structures being the more or less developed eggs. The duct — oviduct — which conveys the eggs outwards is widely open at its upper or anterior end.
The more posterior part of its interior is lined with long deli- cate processes, or close-set villi, which secrete the material of... the egg-shell. Posteriorly the oviduct opens into the cloaca.
The eggs or ova will be further noticed when we come to speak of the development of Birds.
The Eespieatoey System.
This system is wonderfully developed in Birds which, as they are specially modified to move in the air external to them, are also specially modified to receive air extensively within them, as has been already stated *.
Birds breathe by the alternate approximation and separation of the sternum and the back. Their separation tends to produce a vacuum, and causes air to rush into the body, while their approximation expels it by contracting the space into which it has been received.
