Key Differences Between Killdeer and Plovers

Here are some key differences between Killdeer and Plovers:


  • Killdeer: Killdeer are generally larger shorebirds, with a more substantial body size. Their body shape is relatively slender, and they exhibit moderately long legs, allowing them to forage in various habitats.
    The long tail of a Killdeer is edged with white, which is a distinctive feature. This larger size contributes to their overall appearance and behavior.
  • Plovers: Plovers, encompassing a diverse group of shorebirds, exhibit varying sizes. However, in comparison to Killdeer, many plover species tend to have a more compact body structure. They often possess short to moderate legs and may display a rounded body shape.
    This range of sizes within the plover group reflects their adaptation to different ecological niches and habitats.


  • Killdeer: Killdeer have distinct coloration, with a brownish-gray upper body and a white underbelly.
    This coloration provides camouflage in a variety of habitats where they are found, such as farm fields, lawns, and wetlands. The contrasting colors help them blend in and avoid detection from predators.
  • Plovers: Plovers exhibit a range of color variations within different species. Generally, their coloration includes shades of brown, gray, and white.
    This color combination is also adapted for their habitat, often found along sandy beaches, mudflats, and other coastal areas. Their color patterns aid in blending with their surroundings while they forage and nest.

Breast Bands

  • Killdeer: Killdeer are recognized by the presence of two distinctive black breast bands across their white chest.
    These bands are a key identification feature and set them apart from many other shorebird species. The bands provide a visual contrast against their plumage, making them easily recognizable.
  • Plovers: Breast band patterns vary among different plover species. Some plovers may have subtle markings or bands, while others may lack distinct bands altogether. Instead, they might display other unique markings or color patterns that help differentiate them within their species and from other shorebirds.


  • Killdeer: Killdeer are known for their loud and distinctive vocalization that sounds like their name: “kill-deer.” This call is often repeated and can be quite noisy, hence their scientific name “vociferus,” which means “noisy” or “vocal.”
    The call serves various purposes, including communication between individuals and alerting others to potential threats.
  • Plovers: Plovers exhibit a range of vocalizations depending on the species. While some plovers have melodious or piping calls, others produce sharp and repeated notes.
    Their calls are adapted to their habitats and behaviors, often serving to communicate with mates, signal alarm, or establish territory.


  • Killdeer: Killdeer are highly adaptable and can be found in a variety of habitats, including farm fields, lawns, parking lots, beaches, wetlands, and rivers. They are versatile in their choice of habitat and can thrive in both natural and human-altered environments.
  • Plovers: Plovers are commonly associated with coastal habitats, including sandy beaches, mudflats, shorelines of lakes, and riverbanks.
    These habitats provide them with access to their primary food sources, such as insects, crustaceans, and small prey. Some plover species also inhabit other wetland areas.


  • Killdeer: Killdeer exhibits interesting behaviors such as the “broken-wing” display. When they feel threatened near their nest or chicks, they simulate a broken wing, dragging it along the ground to divert the attention of potential predators away from their vulnerable young. This display is a form of protective behavior.
  • Plovers: Plovers are known for their characteristic “run-stop-peck” feeding behavior. They run quickly along the shoreline, stop suddenly to peck at potential prey items, and then continue their swift movement.
    This behavior allows them to efficiently capture small invertebrates and insects while avoiding the incoming waves.


  • Killdeer: Killdeer construct their nests on the ground, often creating a simple depression in gravel, dirt, or vegetation.
    They may line the nest with small pebbles or debris. Killdeer nests are well-camouflaged and blend into their surroundings. When threatened, the parents might use distraction displays to draw attention away from the nest.
  • Plovers: Plovers also commonly nest on the ground. They create shallow scrapes in the sand, gravel, or soil, sometimes lining them with bits of vegetation or shells.
    Like Killdeer, plovers rely on camouflage to protect their nests, and they often choose nesting sites that provide good visibility.


  • Killdeer: Some Killdeer populations are migratory, especially those that breed in northern regions. They migrate to more temperate or warmer areas for the winter. However, not all Killdeer populations migrate, and some individuals might remain in their breeding areas year-round if conditions allow.
  • Plovers: Migration patterns among plovers vary widely. Some species are migratory, traveling long distances between their breeding and wintering grounds. Others are partially migratory, while a few are non-migratory and remain in their breeding areas throughout the year.

Leg Length

  • Killdeer: Killdeer have moderately long legs, which allow them to navigate various habitats, including wetlands, shorelines, and fields. Their leg length is adapted to their foraging behaviors, enabling them to wade in shallow water and move efficiently on land.
  • Plovers: Plovers have a range of leg lengths depending on the species. While some plovers have short legs suited for running along shorelines, others have longer legs that enable them to probe deeper into the sand or mud for prey items.

Bill Shape

  • Killdeer: Killdeer has a straight bill with a slight curve at the tip. This bill shape is adapted for their omnivorous diet, which includes a variety of insects, worms, and small invertebrates. The bill allows them to capture both terrestrial and aquatic prey.
  • Plovers: Plovers have short, straight bills that vary slightly in shape among species. The bill shape is often adapted to the specific types of prey they consume.
    Some plovers have bills designed for probing into the sand or mud to capture small invertebrates, while others have bills suited for pecking at insects on the surface.


  • Killdeer: Killdeer have a relatively long tail with white edges. This tail feature becomes noticeable in flight and can help distinguish them from other shorebirds. The white tail edges are especially visible when they take off, adding to their distinctive appearance.
  • Plovers: Plovers’ tail lengths vary among species. Some plovers have shorter tails, while others have tails of moderate length. Tail characteristics contribute to their overall body shape and play a role in their flying and foraging behaviors.

Body Shape

  • Killdeer: Killdeer have a relatively slender body shape, which allows them to move swiftly and efficiently across various terrains. Their body shape is adapted for both ground foraging and aerial activities.
  • Plovers: Plovers display a range of body shapes within the group. While some have a more streamlined body form for agile flight, others have a more rounded appearance. Their body shapes are linked to their specific ecological niches and behaviors.

Wing Markings

  • Killdeer: Killdeer have prominent white wing stripes that are visible in flight and when they are on the ground. These wing markings contribute to their visual identity and help distinguish them from other birds during their distinctive aerial displays.
  • Plovers: Plover species exhibit varied wing markings, which can include bars, stripes, and patterns that aid in species identification. These markings are often subtle and provide camouflage during rest and foraging, but they become more evident during flight.

Feeding Habits

  • Killdeer: Killdeer have a generalist diet that includes insects, worms, small invertebrates, and sometimes seeds. They forage in diverse habitats, searching for food both on land and in shallow water.
  • Plovers: Plovers have specialized diets that usually consist of insects, small crustaceans, mollusks, worms, and other aquatic or terrestrial invertebrates. Their feeding habits are closely tied to their specific habitat preferences.

    For example, the Piping Plover is a species of concern in many regions due to habitat destruction and human activity in their nesting areas.

Nesting Behavior

  • Killdeer: Killdeer exhibit a protective nesting behavior known as the “broken-wing” display. When predators approach their nest or chicks, they feign injury, moving away from the nest while pretending to have a broken wing. This display aims to distract the predator and lead it away from the vulnerable nest site.
  • Plovers: Plovers, including Killdeer, often rely on camouflage and their chosen nesting sites’ concealment to protect their nests.
    They may use distraction displays or vocalizations to deter potential threats from their nests and young. Different plover species have their unique behaviors adapted to their specific habitats.

Egg Appearance

  • Killdeer: Killdeer eggs are creamy or pale in color, often with variable speckling. The speckles on the eggs provide some level of camouflage, helping them blend into their surroundings.
  • Plovers: Plover eggs come in various colors and patterns depending on the species. They are typically speckled or mottled with colors that range from pale to more vibrant. Egg patterns and colors are adapted to camouflage the eggs within their nesting habitats, helping to protect them from predators.

Parental Care

  • Killdeer: Killdeer exhibits both parents’ involvement in caring for their young. After the eggs hatch, both the male and female take turns incubating the chicks and guarding the nest. The parents also feed and protect the chicks, teaching them essential survival skills until they are independent.
  • Plovers: Plover species also typically involve both parents in caring for their offspring. Both male and female plovers contribute to the incubation, feeding, and protection of the chicks.
    Plovers are known for their vigilant behavior around their nests and chicks, often performing distraction displays to lead predators away.
