another Cuckoo (Chrysococcyx lucidus) called the 
Shining Cuckoo, which also probably follows the 
same route. Both of them pass over a very wide 
but shallow stretch of sea, from New Caledonia to 
New Zealand, a region that in the early Tertiary 
period was dry land. These birds, ultra-conservative 
like nearly all feathered creatures, are keeping up the 
practice of a great migratory flight, which, when 
first attempted, was an overland journey, but now 
passes over hundreds of miles of open sea. Captain 
Hutton and others who have studied New Zealand 
migrants are, apparently, of opinion that Norfolk 
Island and the Kermadecs are not used as pieds a 
terre, at any rate by all the birds that flock southward. 
And so they make the journey in one long flight. 
That the land birds ever rest on the sea is extremely 
unlikely, and it is, of course, impossible that they 
should ever get food from it. ‘There is another 
bird that certainly deserves mention here—the 
Eastern Godwit (Limosa bauerr). It has been 
found nesting in Alaska and in Northern Siberia 
(74°-75° N. lat.), and in August begins, in vast 
numbers, to move southward, passing along the coast 
of Formosa. It has been observed in Norfolk Island 
—a very interesting fact. But do all the Godwits 
reach New Zealand by this route ? Even if they do, 
we must not assume that they always take a rest on 
Norfolk Island. It may be that they only pause 
there if the weather is unfavourable. It is highly 
probable that some migrant birds cross from Australia 
to New Zealand. The Australian Swallow occa- 
sionally makes its appearance there, and even if it 
pauses to rest on one of the Lord Howe Islands it
