An aerial census of the Aransas NWR and surrounding areas made
February 17, 2000 revealed the presence of a record 185 whooping

a The Big Tree family was overlooked despite extended search.
b A single whooping crane was reported along Highway 774 south of
Austwell in a farm field.
Remarks: Visibility was good throughout the day. A total of 175
whooping cranes were located, including 14 chicks.
Whooping cranes are continuing to leave their Matagorda and San
Jose territories to utilize refuge prescribed burns. A total of 32
whoopers were seen on burns, including 22 cranes on Unit 41E and 10
on Unit 37. Thirteen cranes were found in open bays. No cranes
were at freshwater.
The 31 whooping cranes at Welder Flats ties a record high. An
incomplete census was done on San Jose. Based on distribution,
cranes believed overlooked included 6 on San Jose and 2+1 on the
refuge. Thus, cranes observed totalled 174, with 1 reliably
reported in farm fields, and 9 overlooked, for a total of a minimum
flock of 184 whoopers estimated present at Aransas. Two banded
families have not been observed since December 14. If these two
families return to their territories with no mortality, then the
peak population size would equal 190. The R-YbY pair that had not
been located since December 14 was back on their San Jose
territory. They had probably been in large refuge groups using
Burn 41E for the past two months.
Fourteen family groups were sighted on today's flight, with the Big
Tree family overlooked despite an extended search. An unexpected
find was a family group on the south end of the crane range on San
Jose. The identification of this family is unknown since they have
apparently been staying in large groups on refuge Burn 41E. They
possibly could be an unbanded pair that last winter was
consistently found north of Allyn's Bight on San Jose.
For the third time this winter, two cranes were seen on Dewberry
Island close to Port O'Connor. A grouping of 1+1 had moved from the
refuge over to San Jose, but their territorial identity is unknown.
