Birdsong field guide
Chalk-browed Mockingbird
Mimus saturninus
A widespread South American mimid distinguished by its prominent white supercilium and highly versatile, imitative vocalizations.
What it sounds like
A loud, melodious, and long-winded series of varied phrases, often interspersed with harsh scolding notes and expert mimicry.
Field notes
- It is a highly skilled mimic, capable of incorporating the songs of dozens of other bird species into its own complex repertoire.
- The species often practices cooperative breeding, where non-breeding 'helpers' assist the primary pair in raising young and defending the territory.
- It is a frequent host for the brood-parasitic Shiny Cowbird, though it has evolved some capacity to identify and eject parasitic eggs.
- Unlike many forest-dwelling mimids, this species has benefited from deforestation, as it thrives in human-altered open landscapes.
- Its diet is opportunistic and omnivorous, ranging from various insects and fruits to small vertebrates and the eggs of other birds.
Habitat
Open and semi-open areas, including savannas (Cerrado), pastures, scrublands, and urban gardens.
Range
Eastern and central South America, spanning from Suriname and eastern Brazil through Bolivia and Paraguay to central Argentina.
