I quite agree with Julian. Obviously you cannot put coordinates to some
XVII century specimen that states "Nova Hispania", but between that
extreme and using two or thre GPS to georeferrence to one meter of
precision, there is a lot of room to assign coordinates.
Finally, yes indeed, there are 8192 bird registers from the Carnegie Museum
georeferrenced to degrees and minutes. This means about 1.5 km of
precision. The custodians of that database are Adolfo Navarro and
Hesiquio Benitez, to whom further queries should be addressed, in total
agreement with Robin s philosophy of maintaining some degree of control
