During summer, around 3500 Godwits can be seen roosting on the Tinopai sandbar at high tide. The godwits take on their beautiful brick red plumage indicating they are preparing to breed. In mid March they will begin their 11,000km flight to the Arctic Tundra, with a stop over in SE Asia to rest and refuel. The godwits then give birth in Alaska and wait until their fledglings are strong enough to make the 8 or so day nonstop flight back to New Zealand, arriving around mid September, tired and hungry to the sandbar in Mangawhai Bay.
