As already pointed out in the Red-backed ShrikeLanius collurio (and Isabelline ShrikeL. isabellinus) and the Barred WarblerSylvia nisoria, the Woodchat Shrike and the Orphean Warbler form a species pair engaged in a breeding association. Nest recordings of both species in the same bushes along with behavioural evidence in southern France suggests that this association goes far beyond a simple commensalism (for the sole benefit of the warbler) but might be considered as an anti-predator oriented mutualism whose precise extent evidently needs further observations. Rotkopfwürger und Orpheusgrasmücken gemeinsam im selben Nestträger nistend und weitere Verhaltensbeobachtungen an diesen beiden Arten in Süd-Frankreich lassen, wie schon zwischen Neuntöter (und weiter östlich Isabellwürger) und Sperbergrasmücke erwiesen, auf eine vermutliche Nestfeind-orientierte Assoziation schließen, woraus beide Arten Nutzen ziehen. Weitere Beobachtungen müssen Eigenschaften und Grenzen dieser Assoziation zeigen.
