Population justification: The European population is estimated at 69,700-110,000 breeding females, which equates to 139,000-219,000 mature individuals (BirdLife International In prep.). Europe forms approximately 41% of the global range, so a very preliminary estimate of the global population size is 339,000-534,000 mature individuals, although further validation of this estimate is needed. It is placed in the band 300,000 to 550,000 mature individuals.
Trend justification: The global population is suspected to be decreasing owing to agricultural intensification and destruction of nests by farm machinery, over-use of pesticides and improved locust control, and loss of small mammal and bird prey species due to changing agricultural practices (Ferguson-Lees and Christie 2001). The European breeding population is thought to be decreasing by more than 10% over three generations (BirdLife International In prep.). Very little information is available on Asian breeding populations. Roost counts of overwintering birds in India during 1985-2015 found no significant decline of this species, despite overall declines in harrier numbers (Ganesh & Prashant 2018), however analysis of sightings of Montagu's Harrier in India logged on eBird suggested a moderate decline over the last 25 years (SoIB 2020).
