Grey Plover migration update N° 8

Charlie is ahead of the game


In the past few days Charlie has migrated 340km further north. Now Charlie and Nad are both in Bohai Bay, while Charlie is now at a location even further north than Nad, who has been at Bohai for more than 20 days.

It is of interest to compare the migration journey of Nad and Charlie:


Nad

Displacement from Broome
6,280km
6,350km

Looks like Nad had used a “quick moving strategy” to get to the Yellow Sea area as soon as possible, while Charlie spent a bit longer time fuelling up before moving to the next stop. We can see although it has taken more time for Charlie to arrive at its current location in Bohai Bay, it has actually travelled shorter distance than Nad but made a greater displacement from their starting point in Broome. Let’s see what their next move will be!
