In 2020 we discovered a nest of Barn owls in Monte Grande, our largest woodland. It was in a box designed for the Green-winged Macaw and was placed in our woodland to attract this species. Unfortunately for the Macaws, the Barn Owls found it first and inside we found 5 eggs, 2 of which had already hatched. Up until this time we had only heard this species on one occasion so it was quite a surprise to find it breeding at the reserve.
This species is relatively common in many countries around the world, although in Argentina it has a call that I have never heard in the UK, a little like a tick-tick-tick when it is in flight. It also makes the typical Barn Owl screech and the chicks make a loud hissing call to attract the parents.
The Barn owl is a medium sized owl of around 35cm.It has a heart shaped disc over its face and appears white in flight. It has white underparts and speckled gold and black upperparts.
