In shrikes (Laniidae) social monogamy is commonly occurs reproductive system. However, many kinds of behaviour look like an adaptation to extra-pair copulations were also described. The paper presents a popular synthesis of studies done on behavioural ecology of shrikes in Poland. Major part of study was possible because in Polish farmland still living quite dense and stable population of two shrike species: great-grey shrike Lanius excubitor and red-backed shrike L. collurio. We believe that some obtained findings may help to understand animals behaviour generally, and birds particularly. Especially fact than great grey shrike males offer quality of food to female before copulation, according to mate status: worst to an official social partner, and better to extra-pair female. Moreover, extra-pair copulations were realised in open places, but extra-pair in hidden sites. More details, including information on study area, used methods and statistical analysis, can be find in published scientific papers listed below.
