Greetings all,

The following report is forwarded with permission from Tom Stehn, USFWS biologist and National Whooping Crane Coordinator.

Where applicable, CWS stands for Canadian Wildlife Service; USFWS is US Fish and Wildlife Service. Crane monitoring involves cooperative efforts and support by both countries.

Anyone wanting to contact Tom about the report or the whooping crane projects can reach him via email at: tom_stehn@fws.gov.

------------- begin report --------------


     An aerial census of the Aransas NWR and surrounding areas made
     January 21, 2000 revealed the presence of somewhere between a
     record 185 and 191 whooping cranes.
     Recap of cranes observed: (170)

       Refuge   Lamar   San Jose   Matagorda  Welder  Other      Total
        90+11    2+0     13+0        26+2      24+2          155+15=170


     Remarks:  This census flight was done by pilot Huey McDonald of
     Victoria Air Charter in a Cessna 172, with Tom Stehn, observer.
     Visibility was fairly poor throughout the day due to overcast and
     humidity that continually formed on the windshield.  A thorough
     census effort was completed (7.2 flight hours)

     Only 170 total cranes were located on the flight.  Crane numbers
     found in all areas were less than the last flight on January 4,
     most likely a result of the poor viewing conditions.  Only 15
     family groups were located, the same total as the last flight.  A
     family group was reported January 11th on the Powderhorn Ranch
     north of Welder Flats, which may account for one of the families
     not located on those two flights.  Only 13 whoopers were found on
     San Jose Island.  This compares with last winter when around 35
     whoopers were typically found on San Jose.  This indicates a large
     difference in habitat conditions between winters.

     The cranes are flying extensively to use prescribed burns and
     upland freshwater sources.  On today's flight, 40 cranes were on
     prescribed burns, 23 on unburned uplands, and 2 whoopers were at
     freshwater.   A record 38 cranes were found on one refuge
     prescribed burn (Unit 41E).  This included a single flock of 32
     cranes in an area about 1/3rd the size of a football field, the
     largest concentration of whooping cranes I have ever observed.  No
     whooping cranes were found on Unit 41W that was recently burned.
     The cranes are apparently finding what they need on 41E which is
     closer to the salt marsh.

     The lack of blue crabs in the marsh and the extensive prescribed
     burning program on the refuge has resulted in cranes from other
     wintering areas leaving their territories and utilizing the refuge.
      The 101 cranes located on the refuge is only one less than last
     flight's record high.  Sixteen of the 50 pairs and families present
     on the wintering grounds were NOT located on their territories,
     indicating the large amount of movement this winter.  The radio
     family from south Matagorda Island was first observed in flight
     over the Service Road on the refuge and landed near Long Lake.  The
     Long Reef pair from San Jose was across two bays on Lamar.  An
     adult with a single chick was not located, but could easily have
     been in the chaotic groupings observed on the refuge.  On the
     previous flight they had been on San Jose.

     Food resources have been marginal throughout January.  A shift away
     from feeding on crabs is indicated by the 22 whooping cranes found
     on the census in open bay habitat, aided by moderately low tides.
     An additional 19 cranes were found in the open waters of Mustang
     Slough, Redfish Slough, and Long Lake, waters similar to open bay.
     One whooper on San Jose was seen holding a large hardhead fish.

     On January 13, one whooping crane was reported in agricultural
     fields north of the refuge close to county road FM 774 and may have
     been acting sick.  Efforts to subsequently locate this crane have
     been unsuccessful.
