As the number of reported H5N1 outbreaks in Asia mounts, I am trying to
reckon trends for this spring. Given the profound El Nino Southern
Oscillation (ENSO) effect this year [2007] on Europe and North America, I
am wondering what is known about aquatic Asian bird migrations and ENSO. A
cursory database check finds confusion. Warmer temperatures seem to
decrease some European migrations. But the increased rainfall induced by
ENSO in the Pacific seems to increase bird breeding and migration as a
result of increased tree budding, nut formation, and insect populations.
Does anybody have a clear sense of how periodic global climate
oscillations effect the migratory patterns of aquatic bird species? For
example, are birds that frequent the Asia flyways to Siberia more or less
likely to jump the Bering to Alaska? Are birds in the Atlantic flyway more
or less likely to migrate from Greenland to northern Canada?
