Behavior

Introduction

Forages in the under- and midstory, primarily from 1-3 m above the ground but less frequently to as high as 6-9 m high (Zimmer and Isler 2003). Progresses slowly with short hops. Captures prey by reaching out, gleaning, or with short lunges, from substrates such as green leaves and from stems and branches (rarely from dead leaf clusters) (Zimmer and Isler 2003).

Territoriality

Very little information. Armacost (2012) found the density of Castelnau's Antshrikes to be similar on river islands and on adjacent "mainland" sites: 1.57 ± 0.47 antshrikes/ha on islands compared to 1.79 ± 0.49 antshrikes/ha on the mainland.

Sexual Behavior

Social and interspecific behavior

Solitary or in pairs; rarely associates with mixed species flocks (Zimmer and Isler 2003).
