Editing Bird nest (section)

==In human culture==
[[File:Ciconia ciconia juv small.jpg|thumb|alt=Three long-legged, long-billed black and white birds stand on a huge pile of sticks atop an artificial platform on a pole.|A human-made nest platform in Poland built as a conservation measure and to prevent storks disrupting electricity supplies through nesting on pylons. Three young [[white stork]]s are on the top of the nest and two [[Eurasian tree sparrow]]s are perching on the side of the nest.]]

Many birds may nest close to human habitations. In addition to [[nest box]]es which are often used to encourage cavity nesting birds (see below), other species have been specially encouraged : for example nesting [[white stork]]s have been protected and held in reverence in many cultures,<ref>{{Citation |last=Kushlan |first=James A. |year=1997 |title=The Conservation of Wading Birds |journal=Colonial Waterbirds |volume=20 |issue=1 |pages=129–137 |doi=10.2307/1521775 |jstor=1521775 |postscript=.}}</ref> and the nesting of [[peregrine falcon]]s on tall modern or historical buildings has captured popular interest.<ref>{{harvnb|Cade|Bird|1990}}</ref>

Colonial breeders produce [[guano]] in and around their nesting sites, which is a valuable fertilizer from the Andean Pacific coast and other areas.

The saliva nest of the [[edible-nest swiftlet]] is used to make [[Edible bird's nest|bird's nest soup]],<ref name="Couzens">{{Citation |title=Top 100 Birding Sites of the World |first=Dominic |last=Couzens |pages=85–86 |publisher=University of California Press |location=Berkeley, CA |year=2008 |isbn=978-0-520-25932-4}}</ref> long considered a delicacy in China.<ref>{{Citation |title=They Eat That?: A Cultural Encyclopedia of Weird and Exotic Food from Around the World |first1=Jonathan |last1=Deutsch |first2=Natalya |last2=Murakhver |page=17 |publisher=ABC-CLIO |year=2012 |isbn=978-0-313-38058-7 |location=Santa Barbara, CA |url=https://books.google.com/books?id=kcikMWmnQm4C&pg=PA17 |url-status=live |archive-url=https://web.archive.org/web/20130604193533/http://books.google.com/books?id=kcikMWmnQm4C&pg=PA17 |archive-date=4 June 2013 }}</ref> Collection of the swiftlet nests is big business: in one year, more than 3.5 million nests were exported from Borneo to China,<ref>{{Citation |title=Biology of Birds |first1=D.

Some species of birds are considered nuisances when they nest in the proximity of human habitations. [[Feral pigeons]] are often unwelcome and sometimes also considered as a health risk.<ref>{{harvnb|Haag-Wackernagel|Moch|2004}}</ref>

The [[Beijing National Stadium]], principal venue of the [[2008 Summer Olympics]], has been nicknamed "The Bird Nest" because of its architectural design, which its designers likened to a bird's woven nest.<ref>{{cite web |url=http://www.bjghw.gov.cn/forNationalStadium/indexeng.asp#11 |title=Competition entries for design of Beijing National Stadium |publisher=Beijing Municipal Commission of Urban Planning |access-date=25 February 2008 |archive-url = https://web.archive.org/web/20080220015738/http://www.bjghw.gov.cn/forNationalStadium/indexeng.asp#11 <!-- Bot retrieved archive --> |archive-date = 20 February 2008}}</ref>

In the 19th and early 20th centuries, [[naturalist]]s often collected bird's eggs and their nests. The practice of egg-collecting or [[oology]] is now illegal in many jurisdictions worldwide; the study of bird nests is called '''[[caliology]]'''.<ref>{{Citation |last=Dixon |first=Charles | year= 1902| title= Birds' nests| publisher=Frederick A Stokes |location=New York |url=https://archive.org/details/cu31924000206114 |page=v}}</ref>
