Hi Chris (x2), John, Philip & Ed,
I agree with John & Chris that the birds look like 1st winter White-winged
Terns.
And yes, Ed is right, both IOC and Clements call them White-winged Tern.
However, the old name was White-winged Black Tern (no hyphen), which is likely
a more descriptive name and not a classifier for a group (Chlidonias doesn't
stand for 'Black-Tern'; it rather stands for 'Marsh-Tern'). This is in contrast
to the hyphenated birds that Philip mentioned, which all classified a
group: Black-Cockatoo is used only for Calyptorhynchus, Bronze-Cuckoo stands
for Australian Chrysococcyx (with Black-eared Cuckoo being the exception),
Reed-Warbler describes a number of Acrocephalus.

Hi Phillip,
Technically now isn't it White-winged Tern to be in line with IOC naming?
Thus making the second hyphen no longer required.
Cheers,
