Summary The process of cranial pneumatization in the Zebra Finch Taeniopygia castanotis is substantially similar to that described in the House Sparrow Passer domesticus , but is completed somewhat earlier. Full pneumatization of the cranium is usually attained between 138 and 153 days from hatching, though in some birds it may be retarded. A series of diagrams, representing 41 stages in the process, enables the ages of young birds to be established.
