Each year once the breeding pairs of ospreys have safely returned or established themselves with new mates our attention turns to which other birds might be sighted this year. Ospreys often make their first return to the UK as two-year-olds, it is rare for them to breed in the year of their first return. Instead they visit a number of different areas looking for potential mates and territories for the following or subsequent years.
