The Journeys
Now
that our birds are busy breeding, it is a good time for us to look back at the
magnificent journeys that they have made.
Nad
had used 51 days in total migrating from Broome to breeding ground in Sakha
Republic, Russia. The total distance travelled is 10,942km. Charlie spent 2
days less than Nad from Broome to breeding ground also in Sakha Republic (49
days). The total distance travelled is also slightly shorter (10,642km).
Both
Nad and Charlie used 4 days to migrate from Broome to China non-stop. Nad
covered 4,873km with average speed of 47kph, which is the longest non-stop
flight recorded for Nad. Charlie covered 4,651km with average speed of 45kph,
which is the maximum average speed recorded.
They
have both made 5 stops in China but with very different tactics. Nad spent 32
days in China in total, with over 90% of time (29 days) spent at the east coast
of Bohai Bay in Hebei Province in the Yellow Sea area, the rest of the time
was spent at 3 inland locations. Charlie only spent 24 days in China, with
only 54% of the time spent in the Yellow Sea area, the rest was spent in the coastal area of Southern China. The “longest stay” stop-over site was on the
north coast of Bohai Bay in Liaoning Province for 9 days.
Both
Nad and Charlie crossed the Chinese-Russian border in late May. Nad had made 2
more stops in Sakha Republic (one inland location, one coastal location) before
reaching its breeding site, while Charlie had only made 1 stop at an inland
location in Sakha Republic before reaching its breeding site.
Details
and some other fun facts of their journey are shown in the table below:
