Thamnomanes saturninus
The Saturnine Antshrike (Thamnomanes saturninus) is a captivating neotropical songbird belonging to the antbird family (Thamnophilidae), known for its subtle yet striking appearance. Males are primarily dark slate-gray to blackish, often with a white interscapular patch that is usually concealed, and a slightly paler belly. Females exhibit a more contrasting plumage, typically duller gray above with a chestnut to rufous-brown crown and nape, and ochre to rufous underparts, sometimes with a gr...
Primarily inhabits the understory of humid lowland terra firme and seasonally flooded forests. Typically found at elevations below 500 meters, though occasionally recorded up to 900 meters in foothill regions.
Feeds predominantly on a variety of arthropods, including insects (e.g., orthopterans, beetles, caterpillars) and spiders, typically caught by sally-gleaning from leaves and branches.
Saturnine Antshrikes are highly social, frequently acting as "nuclear species" in mixed-species foraging flocks, leading these groups through the forest understory. They are active during daylight hours, typically roosting singly or in pairs within dense foliage at night. Foraging primarily invol...

- The Saturnine Antshrike is often considered a "nuclear species" in mixed-species foraging flocks, meaning it plays a pivotal role in initiating and maintaining the movement of these groups through the forest. - Unlike many antbirds that follow army ant swarms, this species is not an obligate an...
