Feathered Life follows the history of birds and dinosaurs through a series of spectacular successes and great catastrophes across some 250 million years of the Earth's history. Traditionally, similar histories have confined themselves to interpretations of variations in bones and a few other morphological features. That evidence has proven somewhat treacherous. In particular, gaps in the fossil record of very small species have weakened our knowledge of dinosaurs. Even modern studies of skeletal variation in living birds have failed to produce wholly reliable family trees.

Autorenporträt
Gary Kaiser spent 30 years as a migratory birds biologist in Environment Canada. He specialized in the capture and banding of a wide variety of birds. On retirement, he transferred his knowledge of living birds to fossils and has worked on bones from the west coast of Canada and on fossil eggs from ancient breeding colonies in Argentina and Romania. This is his second book on the history of birds. In 2007 he published The Inner Bird: structure and evolution.
