Description General Info
Description
The double-striped thick-knee is a medium-large wader with a strong black and yellow bill, large yellow eyes, which give it a reptilian appearance, and cryptic plumage. The adult is about 46 to 50 cm (18–20 in) long and weighs about 780 to 785 g (27.5–27.7 oz). It has finely streaked grey-brown upperparts, and a paler brown neck and breast merging into the white belly. The head has a strong white supercilium bordered above by a black stripe. Juveniles are similar to adults, but have slightly darker brown upperparts and a whitish nape. The double-striped thick-knee is striking in flight, with a white patch on the dark upperwing, and a white underwing with a black rear edge.

Feeding Habits
Double-striped Thick-knee predominately consumes invertebrates such as worms and insects, with molluscs, lizards, and small rodents supplementing its diet. It typically forages nocturnally, employing a slow and deliberate hunting method. Unique dietary traits include a preference for specific invertebrates depending on availability.
Habitat
Double-striped Thick-knee occupy habitats ranging from low woodlands to savannas, including areas where forests intermingle with grasslands, and coastal grasslands resembling salt marshes. They have an affinity for savannas characterized by jaragua grass interspersed with occasional trees and scrubs, often shaped through deforestation and maintained by cattle grazing. Habitually, these regions are susceptible to dry season fires. Additionally, double-striped Thick-knee can be found in brushy, dry grasslands near coastal regions, exhibiting a degree of separation from human settlements.
