Habitat selection and foraging success of Hen Harriers Circus cyaneus in west Scotland
@article{Madders2000HabitatSA, title={Habitat selection and foraging success of Hen Harriers Circus cyaneus in west Scotland}, author={Mike Madders}, journal={Bird Study}, year={2000}, volume={47}, pages={32 - 40} }
The foraging behaviour of Hen Harriers breeding in west Scotland was studied in a variety of afforested and moorland habitats. Time budget information from sample areas, stratified by habitat type and controlled for nest distance, was used to investigate habitat selection. Preferences were then related to measures of foraging performance in each habitat. Hen Harriers foraged preferentially over young first rotation coniferous forests, and selected heathland and grassland habitats ahead of…

A significant difference in capture rates was found, with harriers on managed grouse moorland capturing prey at a greater rate than elsewhere, supporting the idea that prey were more available on grousemoorland.

Selection of nesting habitat by Montagu's Harriers Circus pygargus and Hen Harriers Circus cyaneus in managed heaths

To encourage the breeding of Montagu's Harriers, the planting of pine should be avoided and the heath should be rejuvenated before it reaches 1.80 m in height.
Spatio‐temporal shifts in gradients of habitat quality for an opportunistic avian predator
- Environmental Science

Results were consistent with adaptive habitat choice in relation to the previous year's spatial variation in fitness: higher associations between fitness and distance to the lake resulted in higher density variations in the following year, in turn related to the availability of fish, the main local prey.

Behavioural Interactions between Hen Harriers and Their Moorland Prey

- 1992
Observations of harriers hunting and at the nest indicated that once they had caught a grouse chick they rarely returned to the same brood to catch another, and increasing grouse density resulted in harriers spending less time attacking each brood.
The effect of Hen Harriers and other predators on Red Grouse populations in Scotland
- Environmental Science, Biology

It was apparent that the effects of predators would be greatest on low density grouse populations, at these low densities, their impact will depend upon grouse breeding success and the degree of overwinter mortality relative to movement between estates.
