Threats to New Zealand falcon/kārearea
Chicks in ground nests are vulnerable
Threats to the New Zealand falcon are not well understood. The New Zealand falcon is listed as a threatened species by DOC due to population decline.
Predation
Although still widespread where suitable habitat exists, numbers have declined and predation by cats and hedgehogs is emerging as a problem for ground nesting falcons.
It is likely that stoats and other mustelids prey on eggs and nestlings in ground and tree nests, and rats may do the same. A recent study suggests that adult falcons are less able to defend their nest from predators that previously thought. More research is needed in this area.
Loss of habitat
Forest dwelling falcons often nest in emergent rimu and other large forest trees. Continued selective logging of such trees reduced available nesting habitat.
Human impact
Like many birds of prey overseas, New Zealand falcons are also threatened by electrocution on power poles containing transformers.
Despite their fully protected status, New Zealand falcons are still shot by people, particularly when falcons occasionally kill racing pigeons or chickens.
Recently a new threat to New Zealand falcons has emerged in the form of wind farms. High mortality rates have been reported for some birds of prey at several overseas wind farms due to collision with the rotating turbine blades. The construction of wind farms in New Zealand falcon habitat may expose it to similar risks. Abandonment of traditional habitat due to wind farm construction is a possibility that needs study.
