What Happened to the Whooping Crane Eggs? The empty nest of whooping crane pair#302 and #209 was found April 28, 2006 on their territory in Monroe County, Wisconsin. The clutch was likely lost during the night or early morning. No egg remains were found in or near the nest. The pair had been incubating since April 13. This was their first nest together.
