SPECIES ACCOUNTS 
Wedge-tailed Shearwater 
Fourteen Wedge-tailed Shearwaters were seen in the grid this month. 
All were ligh phase birds. This species was absent from the grid last 
month, and its presence now represents the return of the species to 
, the breeding grounds. 
Sooty Shearwaters 
. * 
Twenty-eight birds believed to be this species were seen this 
month. None were seen last month. Many of the birds seen had the 
characterstic white underwings, but one was recorded as having dark 
4 
underwings. This bird may have been one of that proportion of Sooty 
Shearwaters that have dark underwings. It is, however, possible that 
it was a Sl^Jender-billed Shearwater. 
The birds were moving in a northwesterly direction. If their 
direction of flight is indicative of origin, it is likely that these 
< 2 , / represent South American birds. Since the frequency of occurance 
increased during each day spent in the grid, these Sooty Shearwaters 
probably represented the first spring migrants. 
Mot tled Petr el 
One bird was identified as this species. The grid may represent 
a fringe area for the migration of this species, as greater numbers 
were seen southwest of the grid area. All of the Mottled Petrels 
observed both in and outside the grid were moving in a northerly 
direction.
