Sounth American Ovenbird builds an Elaborate Home

These birds have been hard at work setting up their new nest in time for the breeding season.


This series of photographs gives an insight into the elaborate process that South American ovenbirds, also known as el hornero (the house builder), go through to create their home, complete with a dome-shaped roof.

Using clay or mud mixed with fibres, hair or straw, the male and female ovenbirds work together to build the walls of their nest gradually during the winter months, allowing the tropical sun to bake the mud until it is rock hard.

After picking an appropriate spot the walls go up first and are finished with the roof.
Then they build a narrow, curved entrance and dividing wall to create the breeding chamber which the female bird lines with grass and feathers, a process which can take months to complete.
After mating, the female lays three to five eggs that hatch after just 20 days because of the warmth trapped inside the nest.
