Wedge Island in St. Margaret's Bay, Seabright, Halifax Co.

Great Black-backed Gull, Larus marinus.  Adults and immature.  Several  
corpses of both adults and immature were also found in the brush and  
on the shore area.  Nests on the island.
Herring Gull, Larus argentatus.  Very common, adults and immature.  
Nests on the island.
Double-crested Cormorant, Phalacrocorax auritus.  There is a breeding  
colony in the spruce trees (which have been killed after several years  
of cormorant white-washing activity).  Perhaps 60 nests.  Fewer  
immature individuals than a week ago, but one was seen with the fuzzy  
appearance of the very young cormorants.
Song Sparrow, Melospiza melodia.  This is the only passerine commonly  
seen on the island.  It probably breeds there, although I have not yet  
located an active nest.  The birds sit on the raspberry "canes"  
calling or just looking about, and pop down into the thick raspberry  
bushes for shelter.
Bank Swallow, Riparia riparia.  Nesting holes seen at top of the  
cliffs at the south end of island, but no birds (it perhaps being too  
late in the season).
Rudy Turnstone, Arenaria interpres.  I watched a group of six in their  
winter plumage, as they preened, foraged among the beach rocks, and  
picked off flies from the beached seaweed. At one point two  
individuals sat resting in the dry seaweed as if nesting.  I could  
approach to within 3 or 4 m.  They were not around the following day.   
Most probably migrants.

Spiders
Araneus diadematus.  Abundant, building webs across gull paths in the  
brush.
Araneus trifolium.  Several females were seen, having built large webs  
across gull pathways.  The color varied with host plant: those living  
in raspberry have pinkish abdomens, colored like the berries; those on  
goldenrod have yellow abdomens.  The patterns are in both cases the  
same.  Has anyone ever described this almost chameleon-like ability?
