Curlew Chick
Curlew Chicks hatch in late June and are almost immediately ready to leave the nest. The coloring and pattern of the downy chicks provides camouflage to protect them from avian and mammalian predators. Chicks follow their parents on long hikes to feeding areas. Curlews also migrate long distances each year.
