The killdeer (Charadrius vociferus) is a large plover found in the Americas. It was described and given its current scientific name in by Carl Linnaeus in the 10th edition of his Systema Charadriidae. 1 Supplementary Material Online Harnessing plasticity to understand learning and treat disease.

They consume, digest and make use of dead and dying vegetation. Some species also eat the waste of herbivores, which can contain undigested cellulose. In some places, termites are the most important factor in breaking down cellulose. Without them, dead trees and herbivore waste wouldn't decompose normally -- they would gradually pile up, making it harder for animals to migrate and find food.

Many homes and other human structures fit the bill for termite food because they're made of dead wood. Termites can't differentiate between the inside of a dead tree and the walls of a person's house.

In some parts of the world , termite attacks on homes are so prevalent that people have adapted, building their homes on stilts lined with termite deterrents, like pieces of metal and pie pans.

The only time when they are not in the presence of a parent is when the parents are mating or responding to a predator or aggressive conspecific. When a pair has two broods, the second is usually attended by just the male who is able to hatch the eggs on his own, unlike the female [25]. In this case, the male does not spend most of the time standing; the amount of time it does stand, though, stays constant as the chicks age.

Like attentive adults in two parent broods, the sole parent increases the time spent foraging as the young age. The young fledge about 31 days after hatching, and generally move to moister areas in valleys and on the banks of rivers. They may be cared for by their parents for up to 10 days after they fledge, and exceptionally for 81 days after hatching.

Breeding starts after one year of age. The killdeer feeds primarily on insects especially beetles and flies , in addition to millipedes, worms, snails, spiders, and some seeds. It opportunistically takes tree frogs and dead minnows. Standing water alone does not have a significant effect on field choice unless combined with cattle. The killdeer uses visual cues to forage.

An example of this is "foot-trembling", [31] where it stands on one foot, shaking the other in shallow water for about five seconds, pecking at any prey stirred up. The former feeds the most before and during egg-laying, the least when incubation starts as there is little time to feed , with a return to high levels after.

When the moon is full, it feeds more at night and roosts more during the day. Foraging at night has benefits for this bird, including increased insect abundance and reduced predation. The killdeer is parasitized by acanthocephalans , cestodes , nematodes , and trematodes. Predation is not limited to eggs and chicks: The parents use various methods to distract predators during the breeding season. One method is the "broken-wing display", [35] also known as "injury feigning". When the bird has the attention of the predator, the former turns its tail towards the latter, displaying the threatening orange colour of the rump.

It then crouches, droops its wings, and lowers its tail. This can be fatal, however, to the displaying bird. The intensity of the responses to predators varies throughout the breeding season.

During egg-laying, the most common response to predators is to quietly leave the nest. As incubation starts and progresses, the intensity of predator responses increases, peaking after hatching. This is probably because it is worth more to protect the young then, as they are more likely to fledge. After hatching, reactions decrease in intensity, until a normal response is calling. This is because the young become more independent as they age. The killdeer is considered a least-concern species by the IUCN.
