Where You’ll See Killdeer

Killdeers are found across North America and in some parts of South America. They are native birds in the Nearctic and Neotropical regions and can sometimes be seen in Central America, the Caribbean, the United States to Mexico.

Killdeers are resident or medium-distance migratory birds. It has been found that these birds don’t migrate unless they need to, and this is only when the temperature is too cold for them.

Breeding season usually starts early spring, around mid-February. The migration begins from August to September, depending on the temperatures. If warm weather continues, some Killdeers stay until November.

Diet and Feeding Preferences

The Killdeer’s diet mostly consists of insects. These birds prefer eating invertebrates the best such as earthworms, snails, crayfish, grasshoppers, and beetles. When insects are not primarily available, Killdeers will eat berries or seeds left on the ground by farmers.

Nesting

Killdeers are monogamous birds, and pairs would usually form around spring. Male Killdeers are the ones who claim territory before they attract a mate.

Tips for Birdwatchers On How To Attract Killdeer

Killdeers are one of those birds that don’t visit bird feeders as they can be timid. However, if you want to attract them, having a home near the shore with a wide-open lawn is ideal. Then, try to scatter some seeds in your area. But the best tactic is to make your lawn more insect-friendly. So don’t use pesticides and other chemicals to get rid of insects because the killdeers can do that for you.
