Tylli syo mielellaan kaikenmaailman hyonteisia, matoja, toukkia ja jonkin verran siemenia. Jos se kokee pesansa olevan uhattuna, se teeskentelee olevansa siipirikko houkutellakseen saalistajan pois pesalta.
The Killdeer feeds by ground gleaning, searching for insects, other invertebrates, and small seeds. It may also glean insects from low-growing foliage.
When defending a nest or hatched young, a parent performs distractions displays. The bird may drag one wing on the ground, as if broken, or it may run some distance from the actual nest area and squat on the ground, feigning the existence of a nest in that location.
