I have just asked for and received an electronic copy of a paper on Silver Y migration for the SMG's interest:

Wind Selection and Drift Compensation Optimize Migratory Pathways in a High-Flying Moth
Jason W. Chapman, Don R. Reynolds, Henrik Mouritsen, Jane K. Hill, Joe R. Riley,1 Duncan Sivell, Alan D. Smith and Ian P. Woiwod.

If anyone would like an electronic copy, please let me know. 10 pages in total including supplementary data, about 500Kb.
