settled down close to the rock. In the act of settling their 
white under parts became for a moment visible, and then 
instantly the birds remained motionless, some of them 
crouching close to the rock, and as if by magic seeming to 
almost disappear under my eyes. Several times, after 
intentionally turning away, it was difficult to locate the 
birds on looking round again, although they were only twenty 
feet or less away.

I saw several of these large blue Herons fishing on the 
islands, but did not shoot any. This bird seems to prefer 
rock-strewn shores to the banks of rivers and streams, and 
will fly enormous distances in order to feed on the abundance 
of shell-fish and other food which it finds there. In the 
Bermudas there is a regular annual migration from the 
mainland, and I have seen many individuals along the shores 
there. This entails a flight of close on six hundred miles 
across an open sea, without a landmark to guide the 
birds. The migration occurs in spring, and I was told by 
a naturalist on the island that later in the year they all 
disappear. 
Sula sula (Linn.). 
This Gannet was present on the smaller islands of the 
group in large numbers, and was breeding. It invariably 
lays its eggs on the ground, and makes a more elaborate 
nest than Sula cyanops, lining a slight depression in the 
soil among the rocks with roots and pliant twigs. Either 
one or two eggs are laid. I have photographs of these birds 
on their nests taken within four feet of them.
