Greetings all!
The following report is forwarded with permission from Tom Stehn, USFWS
biologist and US 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, plus many volunteers and non-profit organizations along the way.

------------- begin report --------------
An aerial census on April 21, 2004 of the Aransas National Wildlife Refuge and
surrounding areas estimated the number of whooping cranes at Aransas to be 6
adults + 2 young = 8.
Recap of cranes observed: (8)
adults + young
Refuge 6 + 2
All other areas 0_
Total 6 + 2 = 8*
* 3 adults and 2 juveniles started migration during the flight, leaving only 3
subadults at Aransas.
Remarks: Flight conditions were fair with mostly cloudy skies become partly
sunny by noon. The number of whooping cranes found totaled 8. This included the
Pipeline family group, the Behind Middle Pond single adult with chick, one
subadult south of the Pipeline, and a subadult duo on Blackjack Point. The
presence of the two family groups was unexpected since migration conditions had
been excellent April 15-20 with sunny skies and very strong southeast winds.
April 21st is the latest I have ever observed adult whooping cranes still at
Aransas. All eight cranes were found on today's flight before 9 AM. After flying
over the rest of the crane range, the refuge was re-checked at noon and only 3
subadult cranes were found. The two family groups (5 cranes total) had started
migration between 9 and 12 noon on April 21st.
The migration leaving Aransas is just about over with only 3 whooping cranes
still present. Ninety-eight percent of the flock has departed. Whooping cranes
have been reported recently all the way from Texas to North Dakota. All the
eastern whooping cranes have started the migration, with many already back in
Wisconsin.
Habitat: On today's flight, no cranes were observed at fresh water sources,
uplands, burns, or in open bay habitat. Many mudflats were exposed on San Jose
and Matagorda islands as moderately low tides combined with strong southeast
winds blew the water over towards the west side of the bay.
