Undulated Antpitta
Grallaria squamigera · also called undulated antpittas
A loud, resonant call carries through the misty Andean cloud forest, betraying the presence of an undulated antpitta that remains completely hidden within the dense undergrowth, one of the largest antpittas anywhere yet still among the hardest to actually lay eyes on.
Overview
The undulated antpitta, Grallaria squamigera, is one of the largest antpitta species, native to forest and mountain cloud forest habitat across the Andes of South America. Its distinctive scaly, barred plumage, far-carrying call paired with near-total invisibility, and characteristic hopping locomotion make it one of the most acoustically present yet visually elusive birds found anywhere in Andean forest.
A voice without a face
Few birds in the Andes are as reliably heard yet so rarely seen as the undulated antpitta, whose loud calls regularly announce a presence that observers can spend hours failing to actually glimpse within the dense forest undergrowth.
Status
Least Concern, remaining present across suitable forest and mountain cloud forest habitat throughout the Andes.
Undulated Antpitta: common questions
Why is the undulated antpitta so rarely seen?
This species is famously difficult to observe directly despite producing a loud, far-carrying call, spending nearly all of its time hidden within dense ground-level vegetation in Andean cloud forest, making a confirmed sighting a genuine achievement for birdwatchers.
Why is the undulated antpitta named that?
This species has a plumage pattern marked with scaly, undulating barring across the body, a feature that gives the species both its common name and its scientific name, referencing this distinctive wave-like pattern.
How does the undulated antpitta move around?
This species moves across the forest floor by hopping on long legs rather than walking, a locomotion style typical of antpittas as a group, well suited to navigating the leaf litter and dense undergrowth of its Andean forest habitat.
How big is the undulated antpitta?
This species is among the largest members of the antpitta group, noticeably bigger than many of its smaller relatives found across overlapping Andean forest and mountain habitat.
