The Montagu's harrier (Circus pygargus) is a ground‐nesting raptor that breeds mainly in cereal crops in western Europe. We evaluate how the use of agricultural habitats may affect population sustainability in this species, based on simulation analyses, and explore how conservation measures could be optimized. Probability of extinction increased with decreasing harrier productivity, and this trend was accentuated when the carrying capacity (maximum number of breeding pairs) decreased. Harrier… 

Breeding Biology of Montagu's Harrier Circus pygargus in South-Eastern Spain

The reproductive biology of Montagu's Harrier Circus pygargus in Granada province of (south-eastern Spain), based on 184 nests monitored from 2003 to 2014, shows high reproductive success and high productivity, however, this high productivity was achieved thanks to the nest rescue campaigns.

Do voles make agricultural habitat attractive to Montagu's Harrier Circus pygargus?

It is suggested that agri-environmental schemes aimed at increasing the availability of voles in agricultural breeding areas may be an effective management tool for the conservation of Montagu’s Harriers in the northeastern Netherlands.

Breeding biology of the Montagu’s Harrier (Circus pygargus) in east-central Poland and implications for its conservation

In 2005–2011 active conservation and study on the population of the Montagu’s Harrier was conducted in the farmland areas of east-central Poland. The population was estimated at 240–270 breeding

Population trend and breeding biology of Montagu's Harrier Circus pygargus in a natural vegetation site in northeast Spain

The results show the importance of the study area for the conservation of this species in the Iberian Peninsula as it might act as a source of colonists for other areas and suggests that natural habitats might be important for the species elsewhere.

Black Harrier Circus maurus of the Fynbos biome, South Africa: a threatened specialist or an adaptable survivor?

Black Harrier Circus maurus is a rare southern African endemic that may have lost over 50% of its core breeding habitat in the last century as a result of extensive land transformation by

Increasing wild boar density explains the decline of a Montagu’s harrier population on a protected coastal wetland

We studied the rapid decline in the number of breeding pairs (geometric growth rate λ = 0.86; 14 % annual decrease) of a semi–colonial ground–nesting bird of prey, the Montagu’s harrier (Circus

Mismatches between breeding success and habitat preferences in Hen Harriers Circus cyaneus breeding in forested landscapes

During the past century, the upland breeding areas of Hen Harriers in Ireland have been extensively afforested. There is no evidence that this species avoids breeding in heavily forested landscapes

Comparative breeding performance of Marsh Harriers Circus aeruginosus along a gradient of land-use intensification and implications for population management

Unexpectedly, Marsh Harriers breeding in intensively cultivated habitats had higher reproductive success than those breeding in more natural habitats, which, however, hosted higher breeding densities, so overall net population productivity was similar across sites.

Influence of habitat on nest location and reproductive output of Montagu’s Harriers breeding in natural vegetation

We examined distribution and breeding success of semi-colonial Montagu’s Harriers (Circus pygargus) in relation to habitat in Castellón province (eastern Spain). Breeding areas used by harriers at a

Breeding biology of Montagu's Harrier Circus pygargus L. in agricultural environments of southwest Spain; comparison with other populations in the western Palearctic

Clear latitudinal trends were observed on laying date and clutch size compared to other Western Palearctic populations: as laying starts earlier, clutch size declines in southern populations; climate and feeding could be the main factors involved.

Comparative breeding biology of Hen Harrier and Montagu’s Harrier: an 8-year study in north-eastern France

The Montagu’s Harrier should be considered as the more vulnerable of the two species, necessitating conservation measures, such as protection of nests from early harvesting activities, and farming practices that preserve sufficient food should also be promoted.

The results suggest that recent trends in agriculture have had deleterious and measurable effects on bird populations on a continental scale and predict that the introduction of EU agricultural policies into former communist countries hoping to accede to the EU in the near future will result in significant declines in the important bird populations there.

Effect of abiotic factors on reproduction in the centre and periphery of breeding ranges: a comparative analysis in sympatric harriers

Hen harriers are probably best adapted to the most typical conditions at those latitudes, and have probably not developed thermoregulatory or behavioural mechanisms to cope with drought and high temperatures in Mediterranean habitats, in contrast to Montagu's harrier, which is central in its distribution.

The use of conspecific reproductive success for breeding patch selection in terrestrial migratory species

Two models comparing the fitness outcomes of behavioural strategies based on conspecific reproductive success as a cue to assess local environmental quality before selecting a new breeding habitat show that prospecting breeding patches before recruiting is the best strategy if the environment is predictable and contains a low proportion of good patches.
