A two-storey wildlife observatory at the home of one of only two known breeding pairs of ospreys in Wales will be opened officially later.
The 360 degree wooden structure at the Cors Dyfi nature reserve near Machynlleth, Powys, has been built with the help of nearly £1.4m worth of grants.
The first osprey chick in the Dyfi valley for 400 years hatched in 2011.
The site's breeding pair - Monty and Glesni - returned to their nesting ground from Africa in April.
Kim Williams, from the Montgomeryshire Wildlife Trust, says the observatory offers "incredible views" of the ospreys.
