The RSPB is encouraging farmers, birdwatchers and walkers to keep a look out for Montagu’s Harriers, the UK’S rarest breeding bird of prey. In 2016, five pairs were known to have nested in Norfolk and south-west England, and while the core population usually returns to the same nesting areas, it is important that any new or unknown nests are located. Montagu’s Harriers breed on lowland farmland, particularly winter cereals, oilseed rape and field silage. Any possible sightings can be reported to the hotline on 01767 393690 or emailed to firstname.lastname@example.org. Details should include the date, six-digit grid reference if possible and a phone number. All reports treated in confidence.
