Does anyone have access to the list of specific gravity measurements for a number of birds in Saunders J & Manton M 79 A manual of practical vertebrate morphology. Clarendon Oxford? This is the study cited in the Hazlehurst G & Rayner J 92 Paleobiology 18:447 paper.
I am particularly looking for a specific gravity measurement for a very large billed bird such as a toucan or hornbill.
