Goldeneye

Introduction
This striking duck, with its piercing eye and large rounded head, was first recorded nesting here in the 1970s, since when a relatively small but expanding breeding population has become established.
Goldeneye use tree cavities and nest boxes for breeding, our current population centred on northern Scotland but with isolated records from England. The species a range of freshwater habitats for breeding.
Wintering birds join our breeders from October and are thought to be mostly birds from the Scandinavian breeding population. Individuals can be seen widely in winter, occupying both coastal and inland sites, sometimes in large numbers (e.g. 500 plus).

Status and Trends
Conservation Status
Population Change
The Goldeneye has increased substantially from a single-figure breeding population in the 1970s (Eaton et al. 2021). The current population is thought to be around 200 pairs (APEP4), with the majority of the UK population breeding in Scotland, but the more recent trend has not been measured after monitoring of the full Scottish population ceased in 2010 (Eaton et al. 2021)
Distribution
In winter, Goldeneyes are found in coastal areas and a wide variety of freshwater habitats throughout Scotland and northern England, with the exception of some upland areas. Farther south, in England, Wales and Ireland, the distribution is patchier and centred on suitable coastal areas, river valleys and wetland networks. Records of confirmed breeding are concentrated in Strathspey and around the Great Glen in Inverness-shire, along the River Dee in Aberdeenshire, and around Loch Tay in Perthshire. Elsewhere, the only confirmed breeding records are from Northumberland and Avon.

Distribution Change
The number of 10-km squares with probable or confirmed breeding by Goldeneyes increased from 13 to 38 between the 1988–91 and 2008–11 breeding atlases, and includes colonisation of Perthshire and Aberdeenshire.

Seasonality
Goldeneyes are predominantly winter visitors, arriving gradually through September and October, departing through April.

Causes of Change and Solutions
Causes of change
The drivers behind the initial colonisation of Scotland are unclear but the subsequent increases may have been aided by the provision of nest boxes within its core range in Scotland (Dennis & Dow 1984). Predation by Pine Martens has been identified as the most important factor affecting breeding success (Langridge 1996) and there are also concerns about the possible impact of the expanding non-native Mandarin Duck population through competition for nest sites (Cosgrove 2003). There is currently no evidence of any negative impact on the population from these or other factors although the population trend has not been monitored since 2010.

The status of our bird populations: the fifth Birds of Conservation Concern in the United Kingdom, Channel Islands and Isle of Man and second IUCN Red List assessment of extinction risk for Great Britain
Author: Stanbury, A.J., Eaton, M.A., Aebischer, N.J., Balmer, D., Brown, A.F., Douse, A., Lindley, P., McCulloch, N., Noble, D.G. & Win, I.
Published: 2021
Commonly referred to as the UK Red List for birds, this is the fifth review of the status of birds in the UK, Channel Islands and Isle of Man, published in December 2021 as Birds of Conservation Concern 5 (BOCC5). This updates the last assessment in 2015. Using standardised criteria, experts from a range of bird NGOs, including BTO, assessed 245 species with breeding, passage or wintering populations in the UK and assigned each to the Red, Amber or Green Lists of conservation concern.
