Original HBW caption:
Like a true shrike (Laniidae) the Rufous-browed Peppershrike is capable of dealing with large arthropods or even, as here, frogs; it has also been observed killing lizards. However, a study of the stomach contents of this and other Neotropical passerines, compiled from various sources, indicates that consumption of vertebrates is relatively rare: of 131 vireonid stomachs, only two contained vertebrate remains. Vireonids use their feet to hold down large prey while dismembering it with the bill.
