London, Apr 14 : Just like American hummingbirds, African sunbirds have also learnt to hover around a flower to collect nectar, and scientists have found that the tree tobacco plant prompts the birds’ ability to hang around.

Tree tobacco, the South American plant has made its way to South Africa, where sunbirds pollinate it.

The plant produces yellow, tubular flowers and like other plants with flowers of this shape, it depends on nectar-sipping birds for pollination.
