Editing Common cuckoo (section)

==As a biodiversity indicator==

The occurrence of common cuckoo in Europe is a good surrogate for [[biodiversity]] facets including taxonomic diversity and functional diversity in bird communities, and better than the traditional use of top predators as [[bioindicator]]s. The reason for this is the strong correlation between the cuckoo's host species richness and overall bird species richness, due to co-evolutionary relationships.<ref name="Tryjanowski & Morelli 2015">{{cite journal |last1=Tryjanowski |first1=P. |last2=Morelli |first2=F. |year=2015 |title= Presence of Cuckoo reliably indicates high bird diversity: A case study in a farmland area |journal=[[Ecological Indicators (journal)|Ecological Indicators]] |volume=55 |pages=52–58 |doi=10.1016/j.ecolind.2015.03.012|bibcode=2015EcInd..55...52T }}</ref> This may be useful for [[citizen science]].<ref name="Morelli et al. 2015">{{cite journal |last1=Morelli |first1=F. |last2=Jiguet |first2=F. |last3=Reif |first3=J. |last4=Plexida |first4=S. |last5=Suzzi Valli |first5=A. |last6=Indykiewicz |first6=P. |last7=Šímová |first7=S. |last8=Tichit |first8=M. |last9=Moretti |first9=M. |last10=Tryjanowski |first10=P. |year=2015 |title=Cuckoo and biodiversity: testing the correlation between species occurrence and bird species richness in Europe |journal=[[Biological Conservation (journal)|Biological Conservation]] |volume=190 |pages=123–132 |doi=10.1016/j.biocon.2015.06.003|bibcode=2015BCons.190..123M }}</ref>
