Welcome back, birding enthusiasts, to our exploration of Costa Rica’s incredible avian diversity! Today, we delve into the shadows of the rainforest canopy to meet a resident shrouded in mystery – the Black-and-White Owl (Strix nigrolineata).

A Sharpened Silhouette Against the Night Sky

As its name suggests, the Black-and-White Owl is a stunning example of contrasting plumage. This medium-sized owl, reaching lengths of 35-40 cm, boasts a sooty black back that extends from its crown to its tail. Striking white “eyebrows” frame its large, reddish-brown eyes, creating a sharp contrast against the mostly black facial disc. The true showstopper, however, is the bold pattern on its underside. Unlike its uniformly dark upperparts, the Black-and-White Owl’s chest, belly, and vent are adorned with a captivating array of black and white stripes. This striking pattern serves a dual purpose: camouflage during the day and a mesmerizing display during courtship rituals.

A Master of the Night

A true nocturnal creature, the Black-and-White Owl comes alive after dusk. Its keen eyesight and exceptional hearing, aided by its facial disc that funnels sound towards its ears, make it a formidable predator. Soaring silently through the rainforest canopy, it hunts for insects, small mammals, reptiles, and even bats. Its yellow beak and sharp talons make quick work of its unsuspecting prey.

Habitat and Habits: A Rainforest Resident

Primarily found in gallery forests and rainforests, the Black-and-White Owl thrives in the dense vegetation of Costa Rica’s lowlands. It adapts well to various forest types, including wet deciduous and mangrove forests. Interestingly, this adaptable owl isn’t entirely averse to human settlements. Sightings have been reported near plantations and gardens, making it a potential feathered friend for some lucky Costa Rican residents.

Finding the Black-and-White Owl: A Test of Patience

Due to their nocturnal habits and preference for dense foliage, spotting a Black-and-White Owl in the wild can be challenging. However, with a bit of patience and a keen ear, you might be rewarded with an unforgettable encounter. Here are some tips for aspiring owl spotters:

• Nighttime is Key: Your best chance of seeing a Black-and-White Owl is during the evening or early morning hours when it’s actively hunting.
• Listen for the Call: This owl has a varied hooting call, often ending with a distinct, emphatic note. With some practice, you might be able to locate one based on its vocalizations.
• Join a Guided Night Tour: Many Costa Rican eco-lodges, including ours here at [Retreat Name], offer guided night tours specifically designed to spot nocturnal wildlife. Our experienced guides know the owl’s typical haunts and can significantly increase your chances of a sighting.

A Glimpse into the Nocturnal World

While elusive, the Black-and-White Owl is a captivating addition to Costa Rica’s rich tapestry of birdlife. With its striking plumage, impressive hunting skills, and preference for the rainforest’s hidden corners, this owl offers a glimpse into the vibrant world that thrives after dark. So, keep your eyes peeled (and ears perked!) during your nighttime adventures in Costa Rica. You might just encounter this magnificent black-and-white jewel in the heart of the rainforest.
