Migratory departures of waders From north-western Australia:Behaviour, timing and possible migration routes
Migratory activity of waders departing from north-western Australia in March-April 1991 was recorded by field observations and radar tracking. Field observations showed that the species concerned were mainly Bar-tailed Godwit Limosa lapponica, Grey Plover Pluvialis squatarola and Great Knot Calidris...

Migratory activity of waders departing from north-western Australia in March-April 1991 was recorded by field observations and radar tracking. Field observations showed that the species concerned were mainly Bar-tailed Godwit Limosa lapponica, Grey Plover Pluvialis squatarola and Great Knot Calidris tenuirostris. Peak migration took place in the second week of April. Most flocks departed in the late afternoon, never at high tide. A strong correlation was found between the tidal cycle and the timing of departures. The majority of the flocks flew towards NNW. Given that the next stopover site of especially the larger sized waders is in east and south China (Barter & Wang 1990) this observed departure direction is more westerly than a course along the great circle route (0-degree).
