White-eared Puffbird

Identification

The white-eared puffbird is a distinctive round, plump bird measuring 21–22 cm in length and weighing between 48–64 g. Like other puffbirds, it is characterized by its compact body shape and notably narrow tail—an adaptation related to its sit-and-wait feeding strategy. The most striking feature is the medium-sized white ear patch that gives the species its common name, surrounded by a contrasting dark ear patch.

The bird's plumage is fairly subtle. Its crown is dark brown with fine barring, while the back and wings are medium brown with dark rufous speckles and bars. The upper breast is white, extending to a narrow-to-medium white collar around the neck, with white and black flecking on the lower breast. The tail is dark brown and slightly graduated, marked with narrow, widely spaced buffy bars and a pale tip. Its orange bill, tipped with black, adds another identifying feature to this compact puffbird.

Range & Habitat

The white-eared puffbird is found across a large portion of central and eastern South America, ranging from eastern Peru and central Brazil south through Bolivia and Paraguay to northeastern Argentina. The species occupies a diverse range of woodland and forest habitats, including tropical and subtropical dry forests, subtropical and tropical moist forests, gallery forests along watercourses, and tropical savanna. It has also adapted to heavily degraded former forest areas.

Within this broad range, the species shows regional preferences. In southeastern Brazil, it is centered on the Cerrado region and the southeast Atlantic coast from northern Bahia south to the Paraná–Santa Catarina border. The species covers much of the eastern and northern Pantanal and southern areas of the Caatinga. In Peru, where it is rare and local, it favors dry forests and scrub in river valleys between 1,000 and 2,200 meters elevation. The species also inhabits the Amazon Basin headwaters and river systems across its northern range.

Behaviour & Diet

The white-eared puffbird is a sit-and-wait predator, a feeding strategy that explains its compact, rounded body shape. It hunts opportunistically for a diverse array of prey items, including arthropods and small vertebrates. Its vertebrate prey includes lizards, amphibians (even poisonous frogs), and small marsupials, which are commonly captured on the ground.

The bird's invertebrate diet is particularly varied, encompassing social wasps, beetles, homopterans, lepidopterans, and other large insects, many caught in mid-air often along streams. It also takes non-volant prey such as insect larvae, millipedes, centipedes, scorpions, velvet worms, and even crabs. This opportunistic approach to feeding allows the species to exploit a wide range of food sources across its varied habitats.

Best Time & Places to See It

The white-eared puffbird is most reliably observed in the Cerrado region of southeastern Brazil and in the Pantanal, where it is more regularly encountered than in other parts of its range. In Peru, where the species is rare and local, birdwatchers should focus on the dry forest and scrub habitats of the Mantaro, Apurímac, and Urubamba valleys. The species can also be found in suitable habitat throughout its broad range in Bolivia, Paraguay, and northeastern Argentina, as well as in Amazon Basin headwater regions.

As with many puffbirds, locating this species requires patience and attention to its preferred microhabitats. Searching along streams and in open woodland areas where insects are active may increase chances of encounter. The bird's sit-and-wait hunting behavior means it may remain perched for extended periods, making it potentially rewarding to scan suitable habitat slowly and carefully.

Photography Tips

The white-eared puffbird's compact size and relatively sedentary hunting behavior present both challenges and opportunities for photographers. The distinctive white ear patch is the key identifying feature and should be the focus of your compositions—approach from angles that highlight this characteristic marking. The bird's dark crown and the contrast between its white collar and darker back also make appealing compositional elements.

This species often hunts from low to mid-story perches, particularly along streams and in open woodland, making it accessible to ground-level and eye-level photography. Use patient stalking techniques and look for birds perched on exposed branches where they scan for prey. Early morning and late afternoon light will enhance the subtle browns and rufous tones of the plumage and illuminate the white ear patch effectively. A moderate telephoto lens will help you maintain distance while capturing the bird's characteristic round silhouette and diagnostic features in detail.
