Camarhynchus psittacula
The Large Tree Finch, *Camarhynchus psittacula*, is a captivating member of the iconic Darwin's Finches, endemic to the Galápagos Islands and a prime example of adaptive radiation. Averaging about 13 cm (5.1 inches) in length and weighing 20-25 grams, this medium-sized passerine is immediately recognizable by its remarkably large, deep, and conspicuously curved, parrot-like beak, which serves as its most defining field mark. Plumage is generally an olive-gray dorsally, with paler, unstreaked ...
Found primarily in humid highland evergreen forests and deciduous lowland woodlands, inhabiting a wide elevational range from sea level up to the mist-laden cloud forests of the highlands.
Primarily insectivorous, feeding on insects and their larvae, supplemented with some plant material like seeds, buds, and fruits, especially during dry seasons. Forages by probing, gleaning, and tearing bark.
The Large Tree Finch is a diurnal and highly arboreal species, spending its active hours meticulously foraging through the dense vegetation of its island home. Its powerful, parrot-like beak is central to its foraging strategy, enabling it to tear into bark, probe deep into crevices, and even str...
The Large Tree Finch is an avian jewel found exclusively across the central and western Galápagos Islands, a truly endemic species. Its range encompasses larger islands such as Isabela, Santa Cruz, Santiago, Pinta, Fernandina, Pinzón, Floreana, and San Cristóbal, though its presence and populatio...
