Arctic Tern 
Twelve birds of this species were seen in April, all of which were 
headed north. The birds were either in pairs or alone. On two occasions 
birds appeared to be flushed from the water by the approaching ship. 
This species appears to migrate north across the grid area in the spring 
in small numbers. 
Pomarine Jaeger 
Numbers of this species decreased 3^ from 22 in March to lit in 
April, This decrease was accompanied by a dispersal of the species* 
I 
range away from the islands to a more random and widespread distribution 
throughout the grid area. Several birds were seen well over $00 miles 
from nearest land. 
Fhalarope sp. 
Of ten shorebirds seen on the April cruise, a TOP? decrease from 33 
to March, nine were thought to be phalaropes, It has not yet been poss ible 
to identify the species involved. The birds have not yet gotten their 
breeding plumages. All were headed north. On one occasion a phalarope 
■sms seen at fairly close range sitting on the water. The individuals 
seen in the grid area may be young birds somewhat out of their normal 
range. 
Rock Dove 
One bird of this species circled the ship on the last morning of 
the April cruise while still over ten miles from Oahu.
