The northern silvery-cheeked antshrike (Sakesphoroides niedeguidonae) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to northern Brazilian Caatinga habitats and found almost exclusively north of the São Francisco River.[1] Small populations are also reported to be south of the river at Raso da Catarina.[2] The northern silvery-cheeked antshrike was identified as a separate species and split from the silvery-cheeked antshrike (Sakesphoroides cristatus) in 2024 after review of over a thousand specimens and more than one-hundred sound recordings revealed a clear geographical split between the two groups.[3]
Description
[edit]In general the northern silvery-cheeked antshrike is very similar in appearance to the very closely related S. cristatus, with females showing more overt differences than males. Most notably the northern silvery-cheeked antshrike has an overall lighter amber color and shows black and white barring down the tail feathers.[1][4]
Behavior
[edit]The northern silvery-cheeked antshrike has been recorded flycatching and turning leaf litter for ants, spiders, termites, beetles and caterpillars.[4] It is known to forage in pairs or mixed-species flocks.[citation needed]
Very little is known about the birds breeding biology, however males have been observed defending territory and responding to audio playback.[4] The northern silvery-cheeked antshrike's 'loudsong' is slower, longer, and has many more notes than S. cristatus.[citation needed]
Name
[edit]The specific epithet niedeguidonae honors Brazilian archaeologist Niède Guidon, who is credited with exploring prehistoric sites in the Americas in the 1970s.[1][4]
