Predators of the killdeer include various birds and mammals. Its breeding grounds are generally open fields with short vegetation (but locations such as rooftops are sometimes used); although it is a shorebird, it does not necessarily nest close to water. [37], The intensity of the responses to predators varies throughout the breeding season. Because they live so close to people, however, Killdeer are vulnerable to pesticide poisoning and collisions with cars and buildings.Back to top.

[22] When nesting on rooftops, the killdeer may choose a flat roof, or build a nest of raised gravel, sometimes lined with white pebbles or pieces of seashells.

Killdeer (Charadrius vociferus), version 2.0. The adult of the subspecies Charadrius vociferus ternominatus is smaller and paler and greyer than the nominate, and the subspecies C. v. peruvianus is smaller than the nominate and has more extensive rufous feather fringes.

Often seen in dry, flat landscapes, running and halting on the ground in search of insects and earthworms. In The Birds of North America (P. G. Rodewald, editor). This does not appear to be true of the female, which has been observed to not use the same territory if it does not have the same mate. This is because the young become more independent as they age.
