Percussion chipped from the same chert

and flint used for common tools, the Bird

form presented here is recognized as the

'finished product'.

They are neither miniature cores nor

practical tools although some appear to

have been used as scrapers.

Hundreds of intentionally chipped chert

'Birds', in the same abstract form of the

granite 'birds', have been found on the SDM

Site. Many hundreds or thousands more

remain buried in the field and forest.

This fascinating artifact form is now used

to identify other later 'platform burial' sites

around West Michigan.

AND since they are found here, they should

be found all across North America and

possibly back to the source, somewhere in

the Old World.
