ALL THE WHOOPING CRANES HAVE STARTED THE MIGRATION.
An aerial census of the Aransas NWR and surrounding areas made
4/21/99 revealed the presence of 0 adults and 0 young = 0 whooping
cranes. The flight was made in charter aircraft with Tom Stehn as
observer and Tom Taylor, pilot. Peak population this winter was
Recap of cranes observed: (0)
Refuge Lamar San Jose Matagorda Welder Other Total
Remarks: Visibility was excellent throughout the 3.4-hour flight.
Since the previous flight on April 15, an estimated 36 + 5 = 41
cranes have started the migration. A family group was reported
from the Mustang Lake observation tower in the early morning, but
they apparently started the migration. Skies were mostly clear
with south winds at 15-25 mph, ideal migration conditions.
In recent years, a few subadults at Aransas have been lingering
into late April or even early May. It was surprising that no
cranes were present on todays flight. The migration this spring
was about a week ahead of average. One more flight will be
conducted to make sure no cranes were overlooked.
