Pairs of Blakiston’s fish owl mate for life and occupy distinct territories within their forest habitat. In late February and early March, nests begin to be constructed in the hollows of large trees (5). The female lays a clutch of around two eggs, which she then incubates over the 35 days it takes for her offspring to hatch. During this time the male will guard her and provide food (5). Once the chicks have hatched they will remain with their parents for a further 1.5 months (5).
Blakiston’s fish owl is a specialised feeder on aquatic prey such as fish, amphibians and even small mammals. Prey are often seized by walking through the shallows; these birds spend such long periods of time on the ground that they make trails along the riverbank (4).
