Black Noddy vs Antarctic Tern

The Black Noddy and Antarctic Tern can be distinguished by their nesting habits and plumage. Black Noddies are unique among marine terns for building substantial nests in trees and shrubs, while Antarctic Terns are more variable in plumage and size due to their circumpolar distribution.

Look for Black Noddies nesting in trees or shrubs and exhibiting a nodding behavior. Antarctic Terns may vary in plumage and size, so consider their circumpolar distribution and potential migratory patterns.

Black Noddies have a uniform dark plumage, while Antarctic Terns exhibit more variation in plumage and size across different populations.

Black Noddies exhibit gull-like behaviors, such as feeding chicks by regurgitation, and are known for their 'Nodding Display.'

Black Noddies are tree- and shrub-nesting species, unlike Antarctic Terns which have a more varied habitat due to their migratory and resident populations.
