Indeling

Falconidae [familie]
Falco [genus] (11/3)
subbuteo [soort]

The distribution is probably affected by misinterpretation of observations outside the nesting area (due to large home ranges), but might be underestimated in farmland as well (inconspicuous behaviour). Range expansion in farmland in the west and north of the country since the 1970s, but declines in strongholds in extensive woodlands and heaths in the east, where the population suffers from predation by Northern Goshawk and lower prey abundance. About 750-1000 bp in 1998-2000, compared to 1700-2100 in 1985-92.
