A tale of two tails: asymmetry in Great Grey Shrike (Lanius excubitor)
Abstract Background Asymmetry in the wild is a controversial, and to date, unresolved subject. Fluctuating asymmetry (FA) is the developmental instability (intra-individual variation) while, directional asymmetry (DA) expresses the asymmetry of the population mean. Methods We analysed 63 Great Grey...
