Brood parasites are an incredibly interesting group of birds. Instead of going to the trouble of building their own nests and raising their own young, they out-source these functions to other birds. They will lay their eggs in the nests of other breeding birds and allow them to raise their young on their behalf. They achieve this through a number of adaptations. Some species mimic the colour and shape of the host’s egg. Others have chicks with structures in their mouths which hyper stimulate the parents to feed them. The adult or chick parasite will also often kill the hosts’s chicks or remove the eggs in the nest, thus ensuring that the parasite survives. However hosts are not completely helpless to this attack, hosts have co-evolved behaviours such as abandoning a nest if it is parasitised. However some hosts are capable of raising both their own young and a parasite, without any visible cost.

Here we present 25 of best photographs of brood parasites, enjoy! If you would like to share your photographs with us, you can upload them to the Facebook page with species, location and photographer as the caption. We will announce next week’s theme this coming Sunday.
