Arctic Tern? - Whanganui River Estuary

Postby Paul Gibson » Fri Apr 05, 2024 4:41 pm

This morning, I found a lone tern on the Whanganui River Estuary mud, and the short legs called my attention to it. It was with some scattered, red-billed gulls, but apart from some Caspians, there was not another tern in sight. I believe, as do some other birders, that it is likely an arctic tern? I returned this afternoon, but could not locate it again.

Primary pattern suggests White-Fronted Paul.

You are right Adam that the plumage suggests White-fronted, but that is also just like an Arctic immature non-breeding bird - see artwork below from The Australian Bird Guide. However, the bird certainly did not have the legs of a white-fronted, they were really short. Unfortunately, I did not get a picture in flight to see if the primaries were translucent.
