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… 
Hen Harrier Circus cyaneus foraging activity in relation to habitat and prey
TLDR
Investigating foraging Hen Harrier activity in relation to vegetation cover and structure and the abundance of potential prey found conifer forests can provide favourable conditions for foraging harriers during the early growth stages.
The distribution of Hen Harriers in Ireland in relation to land use cover , particularly forest cover
Hen Harriers, Circus cyaneus, were once widespread in Ireland, but have declined in range and population over the past 200 years, through a combination of habitat loss/degradation and persecution
Hen harrier foraging success in relation to land use in Scotland
TLDR
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.
Hen harrier Circus cyaneus nest sites on the Isle of Mull are associated with habitat mosaics and constrained by topography
ABSTRACT Capsule: Hen Harriers Circus cyaneus on the Isle of Mull, UK, are associated with habitat mosaics consisting of moorland, scrub and forestry but avoid grazed land, suggesting that forested
The importance of pre-thicket conifer plantations for nesting Hen Harriers Circus cyaneus in Ireland.
TLDR
There was a positive correlation across study areas between changes in numbers of Hen Harrier nests between 2000 and 2005 and changes in the area of pre-thicket second rotation plantations over the same period.
Factors influencing Hen Harrier Circus cyaneus territory site selection and breeding success
ABSTRACT Capsule: Our findings regarding Hen Harrier Circus cyaneus territory site selection and breeding success in Ireland offer an opportunity for the development of initiatives and conservation
Selection of nesting habitat by Montagu's Harriers Circus pygargus and Hen Harriers Circus cyaneus in managed heaths
TLDR
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
TLDR
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
TLDR
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
TLDR
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.
Distribution of Raptor Foraging in Relation to Prey Biomass and Habitat Structure
TLDR
The spatial distribution of Red-tailed Hawks and Northern Harriers overwintering in central Arkansas was studied in relation to perch availability, plant cover, and small rodent biomass in six habitat patch types to interpret the general distribution as a response to prey biomass availability.

The Decline of the Raven, Corvus corax, in Relation to Afforestation in Southern Scotland and Northern England
TLDR
The prediction is made of a further decline in raven breeding numbers if blanket afforestation continues to expand over former upland sheepwalk, which is based on a geographical parallel and a temporal parallel.
