The Cameroon indigobird (Vidua camerunensis) is a species of bird in the family Viduidae.

There are less than 10,000 Vidua camerunensis in total, which range over 20,000 km2 in the savannah and grasslands of South Africa.

[2] The birds have a distinct blue color with underlying brown feathers and a small white beak to crack nuts and seeds.

However, when a paternity test was done between the different species, it was found that the birds were not reproductively isolated.

For natural selection, it is in the bird's favor to mimic another song compared to other species.

DaCosta et al. found evidence that host mimicry is an important cue for species recognition among the territorial male birds.

In the experimental group, the scientists recorded these calls and played them to the captive birds.

They found that birds tended to respond differently to the audio recording compared to natural singing.

Imprinting and sexual courtships are very important in these type of birds, as they need to behave a certain way to lay their eggs.

[10] These males know that to increase fitness, they need to mate with females who have the highest genetic diversity to pass on to the offspring.

[10] Due to this, there has been molecular analysis done on these birds to show the clades of the phylogenetic tree.
