Killdeer

Fascinating facts about the Killdeer

• Killdeer chicks are led from the nest the day after hatching, guided by parents to dense vegetation where they can hide from predators. About 53% of eggs are lost, mainly to predators. The young are precocial, starting to walk within the first days of their life, and are brooded by one parent at a time until about two weeks old before both parents share care.
• When night falls and the moon is full, killdeer switch to nocturnal foraging, taking advantage of the surge in insect activity and the cover of darkness that lowers predation risk. This behavior is noted only in the nonbreeding season, showing a flexible feeding strategy tied to lunar cycles.
• Killdeer lay four to six eggs, each about 38 × 27 mm, and both parents share incubation for 22 to 28 days, with the male typically incubating at night. Incubation effort varies with temperature: birds incubated 99% of the time at 13 °C, 76% at 26 °C, and 87% at 35 °C, and when it's hot (above 25 °C) parents shade the eggs to cool them. These precise temperature-linked behaviors show how parents fine-tune care to keep embryos at optimal conditions.
• The killdeer's striking "ungulate display", raising wings, flashing its orange rump, lowering its head and charging, can be fatal for the bird performing it, yet it persists as a desperate anti-predator tactic. This extreme sacrifice underscores the high predation pressure on nests, where about half of all eggs are lost, and highlights how the species has evolved bold, high-risk behaviors to protect its young.
• Killdeer nests are shallow scrapes lined with white pebbles or shells, a choice that help conceal the eggs. Studies of similar plovers showed nests with lighter material stayed cooler, and nests that matched egg color suffered less predation.
