The appearance of the flowers of Crotalaria cunninghamii has been debated whether it resembles a bird by natural selection or if it is due to chance. The debate is whether the flowers are bird shaped to ward off unwanted predators or to attract certain pollinators, known as Batesian mimicry, or if it is just by chance that they look like birds and humans have associated the shape of the flower with a bird, known as pareidolia. Michael Whitehead from the University of Melbourne stated that the shape of the flowers are consistent with bird pollination, with its large flowers and long keel on its petals. This makes sense because the predominant pollinators of Crotalaria cunninghamii are nectivorous birds and bees.[7] There are a large number of plants with flowers that look like animals, such as the Dracula simia (monkey orchid) that looks like a monkey or the Phalaenopsis (Moth Orchid) that looks like a moth.[8] These plants have the same debate surrounding their unique appearance.

Another cool thing about the plant from that page:

In a paper written by Ds Davidson, published in 1947, it was noted that the Warnman people, an Aboriginal Australian group, used Crotalaria cunninghamii to make canvas shoes. The Warnman people primarily lived in the Gibson Desert and used Crotalaria cunninghamii fibre shoes to protect their feet from the hot sand and rugged stony desert ground. The way the fibre was constructed was by peeling off the soft bark and then tying the smaller fibres together and tying them around your feet.[11] The Indigenous people of the Little Sandy Desert also used the plant in this way, as well as for belts to hang food, such as goanna, from.[12]

TL;DR: Can be found in Australia.
