High above the verdant canopy of the Costa Rican mountains, a graceful predator slices through the azure expanse. This, my fellow nature enthusiasts, is the Swainson’s Hawk, a majestic visitor gracing our skies during the spring and summer months.

While not native to Costa Rica, these impressive birds utilize our beautiful country as a vital stopover point during their incredible migratory journeys. They breed in the northern reaches of North America, and in the fall, embark on a spectacular southward trek to wintering grounds in South America. Costa Rica, with its diverse landscapes and abundant insect life, provides the perfect pitstop for these tireless travelers.

A Master of the Open Sky

The Swainson’s Hawk is a member of the Buteo genus, commonly known as buteos. These are large, broad-winged raptors, but the Swainson’s Hawk stands out for its slender build and remarkably long wings. Often seen soaring effortlessly on thermals, their wings are held in a shallow V-shape, creating a picture of avian elegance.

Their plumage varies, but most boast a light-colored belly that contrasts beautifully with a dark or reddish-brown chest. The upperparts are typically brown or gray, and their underwings are a sight to behold – stark white wing linings contrasting sharply with dark flight feathers. Males tend to have a distinguished gray head, while females often sport a brown crown.

While soaring allows them to cover vast distances, the Swainson’s Hawk is a skilled hunter when close to the ground. Their keen eyesight allows them to spot prey from afar, and their agile bodies make them adept at maneuvering through grasslands and fields.

A Feast for the Grasshopper Hawk

Despite their impressive size, Swainson’s Hawks have a surprising dietary preference – insects! They are aptly nicknamed grasshopper hawks or locust hawks, reflecting their fondness for these abundant prey items. When grasshoppers or other insects swarm the land, Swainson’s Hawks can be seen congregating in large numbers, feasting on this readily available bounty.

However, they are not averse to a more substantial meal. They will also hunt small mammals, reptiles, and even birds on occasion. Their hunting style is fascinating to observe. They may perch on a fence post or other high point, scanning the landscape for unsuspecting prey. Once spotted, they swoop down with impressive speed and agility to secure their meal.

A Transient Treasure

While their stay in Costa Rica is temporary, the Swainson’s Hawk adds a touch of wonder to our skies. If you’re fortunate enough to spot one during your stay at our mountain retreat, take a moment to appreciate this magnificent raptor. Watch as it soars effortlessly on the wind currents, a testament to the power and beauty of nature.
