Here at our Costa Rican mountain retreat, we take pride in the symphony of birdsong that fills the air each morning. But beyond the familiar melodies, there exist hidden gems, waiting to be discovered by the keen-eyed birder. One such treasure is the Nicaraguan Grackle, a bird with a limited range and an iridescent secret.

The Nicaraguan Grackle (Quiscalus nicaraguensis) is a medium-sized songbird, belonging to the Icteridae family, which also includes grackles and oropendolas. While you might expect them throughout Costa Rica, these shy birds cling to a specific region – the wetlands bordering Lake Nicaragua and Lake Managua, with occasional sightings spilling into northern Costa Rica.

Spotting a Nicaraguan Grackle can be a delightful challenge. Look for them in small flocks foraging in freshwater marshes, grasslands, and occasionally pastures. Their long, graduated tails and fairly long bills make them instantly recognizable as blackbirds. But the true magic lies in their plumage.

The males are a sight to behold. Their entire body is cloaked in a sleek, black coat, but this isn’t your ordinary black. Depending on the light, the feathers shimmer with an iridescent sheen. This mesmerizing effect takes on different hues across the body – violet on the belly and tail, violet-green on the head, back, and breast, and a captivating blue-green adorning most of the wings.

Females, while lacking the male’s dazzling iridescence, are no less beautiful. They share a similar black plumage, but with a touch of brown on the head and back. Their underparts are a lighter shade of brown, creating a more subdued elegance.

Despite their captivating looks, the Nicaraguan Grackle remains an elusive bird. They are far less common than their close relative, the Great-tailed Grackle, and prefer the seclusion of the wetlands. Patience and a good pair of binoculars are key to adding this unique bird to your Costa Rican birding list.

Tips for Spotting the Nicaraguan Grackle:

• Habitat: Focus your search on freshwater marshes, grasslands, and pastures bordering Lake Nicaragua and Lake Managua, with a chance encounter possible in the northernmost areas of Costa Rica like the Cano Negro Wildlife Refuge and Medio Queso wetlands.
• Time of Day: Early mornings and late afternoons are prime birding hours when these birds are most active.
• Listen Up: While their song isn’t the most melodious, their calls can help you locate them. Listen for harsh, rattling sounds.
• Be Patient: These are shy birds, so don’t get discouraged if you don’t spot them right away. Be still, observe, and enjoy the birding experience.

With a bit of dedication and these tips, you might just catch a glimpse of the Nicaraguan Grackle – a dazzling gem hidden amidst the lush wetlands of Costa Rica.
