When Richard walked underneath the trellis arch at the front of the house, he noted baby bird tweets.  Careful inspection revealed a tiny Superb Fairy Wren nest Hidden in the bushy part of the climbing plant.  Adult wrens were protesting loudly, but we did not touch the nest itself.

I had been thinking about repacing this climbing plant with something a little more colourful, but given that the wrens like nesting in it, I am going to leave it be, and plant my showy creeper somewhere else.
