i got to see the changing of the guard just now..
i could tell it was going to happen
i saw the nesting bird look up and
there was a shadow of the landing bird
before it joined the other on the nest.
after the first bird flew off, the in-
coming bird rolled the eggs
...i think this is
more for even heating of them than
comfort as posted above. incubators
turn eggs to distribute the warmth.
it is windy on hornby island today.
