Golden Eagle
Introduction
These majestic birds are restricted to the Scottish highlands and islands, with just a few pairs breeding in southern Scotland and the north of Ireland.
The Golden Eagle population remains broadly stable, despite ongoing persecution, numbering in the range of 400 to 500 breeding pairs, with a much small but growing population in Ireland – the result of a successful reintroduction programme.
Our Golden Eagle population appears to be self-contained, with no evidence of interchange with those elsewhere. The European distribution is split into two bands, running east west and associated with the upland regions at the north and south of the Continent.

Status and Trends
Conservation Status
Population Change
This species is monitored by intermittent single species surveys. The most recent of these in 2015 produced an estimate of 508 breeding pairs and suggested that numbers had increased slightly over a 33 year period (+16%) (Hayhow et al. 2017).
Distribution
Golden Eagles are found throughout the Scottish Highlands and on most Hebridean islands.

European movements
EuroBirdPortal uses birdwatcher's records, such as those logged in BirdTrack to map the flows of birds as they arrive and depart Europe. See maps for this species here.

Survival and Longevity
Survival is shown as the proportion of birds surviving from one year to the next and is derived from bird ringing data. It can also be used to estimate how long birds typically live.

Causes of Change and Solutions
Causes of change
The increases in Golden Eagle numbers have been attributed to reduced persecution following improved legal protection and increased monitoring, but persecution may still be limiting on the population in the central and eastern Highlands (Hayhow et al. 2017). The key recent constraint on populations has been persecution associated with grouse moor management (Whitfield et al. 2004, 2006). A limited number of territories may have been abandoned due to the planting of conifer forests but there is no strong evidence to suggest that recreational disturbance or changes in carrion abundance drive population changes (Whitfield et al. 2007).

Rotational burning of vegetation is a common form of land management in UK upland habitats, and is restricted to the colder half of the year, with the time period during which burning may be carried out in upland areas varying between countries. In England and Scotland, this period runs from the 1st October to 15th April, but in the latter jurisdiction, permission can be granted to extend the burning season to 30th April. In Wales, this period runs from 1st October to 31st March.This report sets out timing of breeding information for upland birds in England, Scotland and Wales, to assess whether rotational burning poses a threat to populations of these species, and the extent to which any such threat varies in space and time.
