------------- begin report --------------
An aerial census of Matagorda Island NWR on April 29, 2003 estimated the number of whooping cranes present at 0. The flight indicated that the last two remaining whooping cranes had started the migration since the previous flight on April 23.
RECAP OF CRANES OBSERVED: ZERO
Conclusions: The two cranes on Matagorda Island last week were not seen by staff on April 27th, so are believed to have started migration during April 24-27. Only Matagorda Island was searched on today's census flight.
The 2002-03 whooping crane season at Aransas is over.
