Cranioleuca dissita
The Coiba Spinetail (*Cranioleuca dissita*) is a captivating member of the Furnariidae family, endemic to Panama's Coiba Island and a few adjacent islets. This relatively small passerine measures approximately 14-16 cm (5.5-6.3 inches) in length and weighs around 12-18 grams, characterized by a slender build and a distinctive long, graduated tail with pointed, 'spiny' feather shafts.

This spinetail inhabits humid lowland forest, dense secondary growth, and forest edges, typically at elevations from sea level up to around 500 meters on Coiba Island.
Primarily insectivorous, feeding on small invertebrates such as insects and spiders, which it gleans from leaves, twigs, and bark.
The Coiba Spinetail is an active diurnal bird, often observed foraging solitarily or as part of mixed-species flocks, moving methodically through the understory and mid-canopy. It employs a gleaning strategy, meticulously searching foliage, small branches, and bark for invertebrate prey. Territor...
