Pied Imperial-Pigeon

[Thyer <>]

Hi all,
      Had an interesting sighting yesterday of two Pied Imperial-Pigeons
sitting out in the rain and cold on the power lines.(it was a miserable
day). They were preening and opening their wings up to catch the rain
drops and presenting different parts of their bodies to the rain to be
washed. One bird had substantial barring on the undertail coverts and
all underparts were buff colour. The other bird had very little barring
and was a clean white underneath. It's unusual to see these Pied
Imperial-Pigeons here before early September, so I am assuming they are
wintering over. Has anyone any thoughts?
