Crane in : Longevity emblem
[162] [more-crane-62] In , the field log for Crane is headed “Longevity emblem.” The figure kept beside that heading is 1. 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. Australia, New Zealand, and southern African English programmes add ice, island and savanna files the North Atlantic does not hold.
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. Wintering red-crowned and white-naped cranes use the Civilian Control Zone. Peace-time development is a documented risk to that accidental reserve.
Chicks imprint on humans and then fail to migrate or pair. Operation Migration ultralights (2001-2015) tried to teach a new flyway. Is the Hokkaido tancho a separate species? No. The resident Kushiro group and mainland migratory birds are one species with different movement strategies.
