This nest blew down from the Erythrina tree during a recent period of strong winds and landed on the verge outside our gate.
It provides an interesting opportunity to see what has gone into its construction. Apart from the expected grass and twigs, I recognise the following items: blue twine, guinea-fowl feathers (a flock of tame guinea-fowl live in a garden not far from our home), narrow strips of plastic, balls of upholstery stuffing, bark, tiny roots, and feathers from unidentified birds. Other items might have blown away in the wind.
I suspect this might be the nest of a Greater Double-collared Sunbird.
