Editing Common buzzard (section)

===Nests===
Common buzzards tend to build a bulky nest of sticks, twigs and often [[Calluna|heather]]. Commonly, nests are up to {{cvt|1|to|1.2|m}} across and {{cvt|60|cm}} deep. With reuse over years, the diameter can reach or exceed {{cvt|1.5|m}} and weight of nests can reach over {{cvt|200|kg}}.<ref name= Ferguson-Lees/><ref name= Brown/> Active nests tend to be lined with greenery, most often this consists of broad-leafed foliage but sometimes also includes [[Juncaceae|rush]] or [[seaweed]] locally. Nest height in trees is commonly {{cvt|3|to|25|m}}, usually by main trunk or main crutch of the tree.<ref name= Ferguson-Lees/><ref name= Brown/><ref name= Cramp/> In [[Germany]], trees used for nesting consisted mostly of [[Fagus sylvatica|red beeches]] (''Fagus sylvatica'') (in 337 cases), whereas a further 84 were in assorted [[Quercus|oaks]].<ref name= Rockenbauch>Rockenbauch, D. (1975). ''Zwölfjährige Untersuchungen zur Ökologie des Mäusebussards (Buteo buteo) auf der Schwäbischen Alb''. Journal für Ornithologie, 116(1), 39–54.</ref> Buzzards were recorded to nest almost exclusively in [[Pinus|pines]] in [[Spain]] at a mean height of {{cvt|14.5|m}}.<ref name= Zuberogoitia/> Trees are generally used for a nesting location but they will also utilize crags or bluffs if trees are unavailable.<ref name= Brown/> Buzzards in one English study were surprisingly partial to nesting on well-vegetated banks and due to the rich surrounding environment habitat and prey population, were actually more productive than nests located in other locations here.<ref>Austin, G.

(2011). ''A record of a Common Buzzard (Buteo buteo) nesting in an abandoned building''. Journal of Raptor Research, 45(3), 275–277.</ref> Pairs often have several nests but some pairs may use one over several consecutive years. Two to four alternate nests in a territory is typical for common buzzards, especially those breeding further north in their range.<ref name= Brown/><ref name= Selas3>Selas, V. (2001).
