?he tv/o individuals were noted in a single sighting on 10 Decer er 
northwest of Howland. Very erratic flight and dangling legs are 
good field characters at close range. This species has been ir¬ 
regularly recorded in low numbers during the fall and winter months. 
Leach’s Storm Petrel (2) • 
white-rumned storm petrels (47+6 nocturnal) 
Density was up to 0.07 during the present survey and is fairly com¬ 
parable with that of 0.09 recorded during October. A drop to 0.04 
during the November survey is difficult to interpret because the 
wintering populations should be fairly stable. Most birds seen

Density was above that of November, but within the expected ran^e

year^ound, but origin may be from any of the south Pacific breed¬ 
ing islands. Of the three specimens collected during the present 
cruise, one was a Jarvis banded bird. Four banded birds have 
been collected to date in the grid; two from Jarvis, one iron 
Christmas and one from Enderbury. 
Blue-faced Booby (229 + 20 nocturnal) 
Density dropped to one half that recorded during November. As 
previously explained, density figures iiuctuate widely depending 
upon the amount of cruise time near the islands. This can oe 
shown very clearly using the present cruise as an example. of
