The Wren will fly in nearby keeping a screen of branches between us while it tries to determine if it is safe to return to the nest box. On this occasion it flew into an evergreen and hopped about from branch to branch calling loudly. The heavy cloud cover this evening necessitated the use of flash and one shot was all I got. Although I sat for another 30 minutes the Wren had had enough.
Although I cannot see into the Wren’s nest I assume that young birds are present. The Wrens are now carrying food and visiting the nest with increasing frequency.
