Last week on Our Changing World, Alison Ballance joined Massey University's Jesse Conklin and Phil Battley, and a team of shorebird experts, in a mission to cannon net bar-tailed godwits at the Manawatu Estuary. In part two of that story the cannons are fired, and the team discover how many data loggers they are able to retrieve from 24 godwits carrying them. They are especially interested in four birds that have carried the data loggers for two seasons.
Don't forget that Keith Woodley's new book 'Godwits: long haul champions' (Penguin Books) is a great source of information about bar-tailed godwits, and that the Asia Pacific Shorebird Network encourages international co-operation in the study and conservation of shorebirds.
