Sometimes Facebook pages can be exciting. I have recently been watching the page for the
Pukorokoro Miranda Shorebird Centre as they record Bar Tailed Godwits (Limosa lapponica
baueri) arriving back on the sandy shores of Kaiaua on the Thames Estuary (I
visited here in May – read about it HERE).
Every year around March (autumn) these medium-sized waders
migrate to western Alaska for the breeding season. Several birds have been fitted with special
tags that allow for satellite tracking of their flights, and they are now
returning one by one to our shores.
On the flight over to Alaska the birds often stop at the
Yellow Sea between China and Korea, but their flight back here is a direct
11,000 – 12,000 km flight with no stops along the way.
Their average flight speed is around 56 kilometres per hour,
with juveniles making their first trip when barely four months old.
About 9.30pm last night, bird 4BWWB dropped unseen (and probably
hungry and exhausted!) onto the Kaiaua mudflats after flying non-stop for over
12,100 kms – a trip of some 8 days and 14 hours.
This is the third season this bird has been followed on her migration.
I never cease to be astonished and amazed by the miraculous
wonders of nature 😊
