'''''Poecile''''' is a genus of birds in the tit family Paridae. It contains 15 species, which are distributed across Europe, Asia, and North America; the European and Asian species are known as '''tits''', and the North American species as '''chickadees'''. In the past, most authorities retained ''Poecile'' as a subgenus within the genus ''Parus'', but treatment as a distinct genus, initiated by the American Ornithologists Union, is now widely accepted.<ref name=hbw>{{cite journal | last1=Gosler | first1=A. | last2=Clement | first2=P. | last3=Bonan | first3=A. | year=2019 | orig-year=2007 | title=Tits and Chickadees (Paridae) | editor1-last=del Hoyo | editor1-first=J. | editor2-last=Elliott | editor2-first=A. | editor3-last=Sargatal | editor3-first=J. | editor4-last=Christie | editor4-first=D.A. | editor5-last=de Juana | editor5-first=E. | journal=Handbook of the Birds of the World Alive | publisher=Lynx Edicions | doi=10.2173/bow.parida1.01 | s2cid=216446005 | url=https://www.hbw.com/node/52340 | access-date=27 August 2019 |url-access=subscription }}</ref> This is supported by mtDNA cytochrome ''b'' sequence analysis.<ref>{{ cite journal | last1=Gill | first1=F.B. | last2=Slikas | first2=B. | last3=Sheldon | first3=F.H. | year=2005 | title=Phylogeny of titmice (Paridae): II.

All the species are roughly similar in size, ranging from 11–15&nbsp;cm, with marsh, willow, and black-bibbed tits marginally the smallest (11–13&nbsp;cm), and sombre tit and mountain chickadee marginally the largest (13–15&nbsp;cm). The plumage pattern is also broadly similar across the genus, with a black or dark brown crown and bib, whitish or pale buffy cheeks, and whitish to buffy underparts. Two species (white-browed tit and mountain chickadee) differ in having a white supercilium. The back and wings are brown to grey-brown or reddish brown, in some with pale fringes on the secondary feathers.<ref name="Hoyo">{{cite book |last=Hoyo |first=Josep del |title=All the birds of the world |publisher=Lynx edicions |publication-place=Barcelona |date=2020 |isbn=978-84-16728-37-4 |pages=574–575}}</ref>

==Behaviour== Many species have alarm calls with a distinctive "chick-a-dee-dee-dee" format, which gives rise to the name 'chickadee'; the number of "dees" depends on the predator and the risk it poses, with more "dees" for high risk predators such as small owls.<ref>[https://www.newscientist.com/article/dn7570-chirpy-chickadees-signal-deadliness-of-predators/ "Chirpy chickadees signal deadliness of predators"]. ''New Scientist''. 23 June 2005. Retrieved 6 March 2019.</ref>

==Ecology== All are birds of mature woodlands and forests, often with a preference for old-growth habitats with plentiful tree cavities for nesting; many, but not all, readily adapt to human provision of food and nestboxes.<ref name="Harrap">{{cite book |last1=Harrap |first1=Simon |last2=Quinn |first2=David |title=Tits, Nuthatches & Treecreepers |publisher=Christopher Helm |publication-place=London |date=1996 |isbn=0-7136-3964-4 |pages=237–294}}</ref>

Several species, including Siberian, marsh and willow tits in Eurasia and mountain chickadee in North America, are food-caching birds. Siberian tit, living in the coldest environment, is the greatest hoarder, with individual birds storing up to half a million food items throughout each year for winter use.<ref name="Harrap1">{{cite book |last1=Harrap |first1=Simon |last2=Quinn |first2=David |title=Tits, Nuthatches & Treecreepers |publisher=Christopher Helm |publication-place=London |date=1996 |isbn=0-7136-3964-4 |page=287}}</ref> Mountain chickadees can hide as many as 80,000 individual seeds each, which they retrieve during the winter. Their ability to do so depends on their spatial memory of the locations. Birds that live in harsher conditions, where their ability to remember the location of food is more important, have been found to have better memory abilities, a larger hippocampus, and more neurons than chickadees that live in milder climates where food sources are easier to find without relying on memory.<ref name="Mason">{{cite journal |last1=Mason |first1=Betsy |title=Total recall: A brilliant memory helps chickadees survive |journal=Knowable Magazine |date=5 September 2019 |doi=10.1146/knowable-090519-1 |url=https://knowablemagazine.org/article/mind/2019/chickadee-memory-food |doi-access=free |access-date=24 February 2022}}</ref><ref name="Pravosudov">{{cite journal |last1=Pravosudov |first1=Vladimir V. |last2=Roth II |first2=Timothy C. |title=Cognitive Ecology of Food Hoarding: The Evolution of Spatial Memory and the Hippocampus |journal=Annual Review of Ecology, Evolution, and Systematics |date=23 November 2013 |volume=44 |issue=1 |pages=173–193 |doi=10.1146/annurev-ecolsys-110512-135904 |url=https://www.annualreviews.org/doi/full/10.1146/annurev-ecolsys-110512-135904 |access-date=24 February 2022 |language=en |issn=1543-592X|url-access=subscription }}</ref>
