Osprey Key Dates

Dates are very important in nature.

Ospreys are migratory so timing is crucial in terms of getting back to the UK in an optimal time to achieve the best breeding productivity. Get back too early and risk a cold spring with food hard to come by and few other ospreys around; get back too late and all of the nest sites and breeding birds are spoken for.

The further north in the Europe ospreys breed the later they tend to come back - for obvious reasons. Ospreys in France return in February and early March whereas those birds breeding in northern Finland may not get back until late April.
