It looks as though the Wren is now nesting in the roosting pocket. It is too dark to see inside so from time to time I have taken a flash photo from about fifteen feet away. Up to yesterday there was nothing to be seen inside. The last photo showed a somewhat blurry occupant which looks to me like the feathers of the Wren.
It is impossibe to focus inside the pouch as it is in complete darkness and I don't want to disturbe Mrs Wren if she is now hatching a few wrenlets.
