Editing Common nightingale (section)

==Distribution and habitat==
It is a [[bird migration|migratory]] insectivorous species breeding in forest and scrub in [[Europe]] and the [[Palearctic]], and wintering in [[Sub-Saharan Africa]]. It is not found naturally in the [[Americas]]. The distribution is more southerly than the very closely related [[thrush nightingale]] ''Luscinia luscinia''. It nests on or near the ground in dense vegetation. Research in [[Germany]] found that favoured breeding [[Habitat (ecology)|habitat]] of nightingales was defined by a number of [[geography|geographical]] factors.<ref name= Wink1973>{{in lang|de}} Wink, Michael (1973): " [http://www.uni-heidelberg.de/institute/fak14/ipmb/phazb/pubwink/1967-79/28.%201973.pdf Die Verbreitung der Nachtigall (''Luscinia megarhynchos'') im Rheinland]".

In the U.K., the bird is at the northern limit of its range which has contracted in recent years, placing it on the red list for conservation.<ref>{{cite web |url=https://www.rspb.org.uk/Images/birdsofconservationconcern4_tcm9-410743.pdf|title=Themes from Birds of Conservation Concern 4|publisher=British Birds|access-date=18 March 2017}}</ref> Despite local efforts to safeguard its favoured coppice and scrub habitat, numbers fell by 53 percent between 1995 and 2008.<ref>{{cite web |url=http://www.bto.org/support-us/past-appeals/nightingale-appeal|title=Nightingale population fallen by 50% |publisher=British Trust for Ornithology |access-date=20 April 2014 }}</ref> A survey conducted by the British Trust for Ornithology in 2012 and 2013 recorded some 3,300 territories, with most of these clustered in a few counties in the southeast of England, notably Kent, Essex, Suffolk, and East and West Sussex.<ref>{{cite web |url=http://www.bto.org/volunteer-surveys/nightingale-survey/latest-news|title=Nightingale survey latest news |date=9 May 2012 |publisher=British Trust for Ornithology |access-date=20 April 2014 }}</ref>

By contrast, the European breeding population is estimated at between 3.2 and 7 million pairs, giving it green conservation status ([[least concern]]).<ref>{{cite web |url=http://blx1.bto.org/birdfacts/results/bob11040.htm|title=Birdfacts — British Trust for Ornithology |date=16 July 2010 |publisher=British Trust for Ornithology |access-date=20 April 2014 }}</ref>
