Crane in 2001: Operation Migration flights · 341
[340] [desk-crane-7] In 2001, the field log for Crane is headed “Operation Migration flights.” The figure kept beside that heading is 2015. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. A few winter basins and nesting marshes hold the Endangered type. Influenza and rice-paddy conversion are tighter than any sprint.
Tall wetland dancers whose red-crowned East Asian population is the atlas type and a conservation bottleneck. Why does this atlas use the red-crowned crane? The taxonomy hero is Grus japonensis -- Kushiro, the Korean DMZ and Izumi. Other Grus species appear as comparison, not as the page type.
How close did whooping cranes come to zero? The Aransas-Wood Buffalo flock was about 21 birds in 1941. That nadir still defines US recovery graphs. What did George Archibald do at ICF? He courtship-danced with a human-imprinted whooping crane named Tex so she would ovulate -- a 1980s method story, not a field census.
A large share of the migratory island population winters on one Kyushu floodplain. Influenza years there are species-level events. Do cranes mate with a lifelong dance? Pairs are typically socially monogamous. The dance is pair-bond and territorial display, not a fairy-tale wedding.
Keep 2001, “Operation Migration flights,” and 2015 together or the note on Crane stops being that year’s record.2001
