High up in the Costa Rican mountains, where the air thins and the emerald embrace of the rainforest loosens its grip, another kind of magic unfolds. Here, on the drier, sun-drenched slopes, a fascinating resident calls this wild haven home: the Double-striped Thick-knee.

For the avid birder, spotting this bird can be a delightful challenge. The Double-striped Thick-knee, aptly named for its two bold stripes framing the head and its impressively thick knees, is a master of camouflage. Its plumage – a symphony of finely streaked grey-brown above and a subtle gradient from pale brown to white below – blends seamlessly with the dry, open habitats it prefers. Add to this its tendency to freeze in place when threatened, and this bird practically disappears before your very eyes.

But don’t be discouraged! The Double-striped Thick-knee isn’t entirely shy. As dusk descends and the mountains cloak themselves in twilight, this bird springs to life. Its large, reptilian-looking yellow eyes, perfect for navigating the night, begin to gleam. It sheds its cloak of invisibility and starts foraging for insects, lizards, and other small creatures that emerge under the cover of darkness.

Listen closely, and you might be rewarded with its haunting, melancholic call. Some describe it as a long, drawn-out whistle, while others liken it to a mournful wail. Whatever your interpretation, this otherworldly sound adds to the mystique of the Double-striped Thick-knee.

While not as readily spotted as its rainforest cousins, the Double-striped Thick-knee is an undeniable treasure of the Costa Rican highlands. Its presence speaks to the incredible biodiversity that thrives in every corner of this remarkable country.

Spotting Tips:

• Look for the Double-striped Thick-knee in dry, open areas with sparse vegetation, particularly at the foothills and lower mountain slopes.
• Visit during the late afternoon or early evening, when they become more active.
• Listen for their long, mournful call.
• Be patient and observant, their camouflage is excellent.

Interesting Facts:

• The Double-striped Thick-knee is a non-migratory bird, meaning they stay in the same area year-round.
• They are classified as “Least Concern” by the IUCN, meaning their population is stable.
• Unlike many wading birds, the Double-striped Thick-knee prefers to run rather than swim.

So, next time you find yourself amidst the cool mountain breezes of Costa Rica, keep your eyes peeled (and ears tuned) for this enigmatic bird. With a little patience and a dash of birding know-how, you might just be lucky enough to catch a glimpse of the Double-striped Thick-knee, a true wonder of the Costa Rican highlands.
