How about developing recording and sonograph technology to the
point where an indeterminate number of individuals can be recorded
and their sonagraphs archived. Say Wilson s Warblers in Alaska.
Someone can then go back to the same areas the next spring and record
territorial fidelity without a mistnet.

If even the chip note is distinctive, someone even more adventurous
might go to Latin American and record hundreds of Wilson s Warblers
hoping that some fast computer can match one of the chips to an Alaska

How does this register on the Sci-Fi index relative to the
resurrection of Passenger Pigeons?
