The Hummingbirds of Monteverde

In Costa Rica along the crest of the Cordillera of Tilarán, is a world of mist and greenery: the cloud forest of Monteverde. Trade winds from the Atlantic bring a steady flow of clouds across the mountain ridges, nourishing an astonishing forest, draped in ferns, moss and orchids. Resplendent Quetzals spend part of each year in this misty realm.

The original Monteverde Cloud Forest Preserve has been augmented by the Bosque Eterno de los Niños – the Children's Eternal Rainforest. The Bosque Eterno was conceived by schoolchildren in Sweden; when I used to go regularly to Costa Rica, fund-raising for the Bosque Eterno was just getting off the ground. It succeeded, and now a magnificent reserve is the result.

Years ago at the entrance to Monteverde Cloud Forest Reserve, a hummingbird gallery, complete with feeders, was established by local folks, including Patricia and Michael Fogden. Today that gallery teems with a truly dazzling array of hummingbirds. When we were there a week or two ago, many, many hummers of eight species were buzzing around the feeders, enchanting everyone who ventured onto the gallery grounds. Here are a few photos for your enjoyment!

The big Green Hermits come only infrequently to feeders. Most of the time they are deep in the forest, pollinating plants like Heliconia.

Tiny Coppery-headed Emeralds used to be scarce at the Monteverde feeders, so I was surprised to see several of them the day we were there. Males blend darkly into the shadows, until they catch the light just right... then, a glorious flash of intense green! This emerald is a Costa Rican endemic, mostly on the Caribbean slope, although it spills over onto the Pacific slope in this region. Like many other tropical hummingbirds, the males gather in small breeding leks and call to attract receptive females.

... to sublime!

 The female emeralds are much more modestly dressed.

Another of Monteverde's smaller hummingbirds is the Magenta-throated Woodstar, endemic to Costa Rica and western Panama. These buzz around, tails often raised, creating a distinctive wing-whir that lets you know they're in the neighborhood. Here's a challenge for you: the nest of this species has not yet been found and described... go for it!

Rather larger is the Green-crowned Brilliant, here sporting the spotlights he uses to dazzle females. This brilliant is a creature of the high, wet mountains, and it ranges as far south as Ecuador (another country that boasts fabulous hummingbirds!)

...and a lovely female brilliant!

Purple-throated Mountaingems are perhaps the most abundant species at Monteverde's feeders. The female is a bright buffy-rufous below and sports a strong mask. Like other hummers, these are VIPs: Very Important Pollinators.

And just in case you're thinking that the species is misnamed...

...the gorgeous male mountaingem is a show-stealer!

Another beauty which seems to me more frequent now at the hummingbird gallery's feeders is the Green Violetear. This violetear occupies highlands from Mexico, all the way down into the Andes of Bolivia. Although its range overlaps that of the other two violetears (Sparkling and Brown), the Green prefers wetter, higher forests, and so is right at home in Monteverde.

Another hummer with a fairly large range (from southern Mexico to Panama) is the little Stripe-tailed Hummingbird. Those bright rufous wing patches are a good field mark. They are quite regular at the Monteverde feeders and in the cloud forest.

One of the most impressive hummers in Costa Rica is the enormous Violet Sabrewing––at 6" long, the biggest hummingbird away from South America. For comparison, our Magnificents are 5.25". Just look at that scintillating deep blue-violet! The sabrewing's range is similar to the Stripe-tailed's: southern Mexico to western Panama. This hummer also feeds often at Heliconia, and the males, like the tiny Coppery-headed Emerald males and the Green Hermits, also gather in leks to "sing" for the females.

Hummingbirds live only in the Americas. What a treasure they are!

The Scissor-tails Are Staging

Here's another image of migrant birds in Costa Rica: just slip into this tropical scene!


The sun and a sliver of new moon are setting in a golden haze over the tropical dry forest of Santa Rosa National Park. Parrots announce their comings and goings. It's March, and hundreds of Scissor-tailed Flycatchers are staging for their spring migration to the States. Glowing rose, they gather to roost in a handful of bare trees. The sunset-lit trees flame with them.


Nighthawks emerge to dive for insects in the darkening void above the golden haze.

A wonderful 2010 to all of you! May your path wind through splendid rainforests and along wild sea coasts, and may you discover the gifts of the land along the way.

An Ordinary Marvel


If we open our eyes and unstop our ears, earth presents us with such ordinary, everyyear wonders, like the routine migrations of animals.

One ancient cycle––the great seasonal pulse of migrating birds––can strike a chord of deep awe in those of us who are fortunate to witness it. Who hasn't rushed outdoors when the primordial rattle of cranes or cry of swans seeps through the windows of daily life? After a long, dark, frozen winter, whose heart hasn't leapt at the appearance of the first hummingbird of the spring, as the tiny glittering miracle hovers for an instant at the kitchen window?

Over the years, Costa Rica has gifted our tour groups with riveting experiences of migration. Consider: it is April in the lowland rainforest of Selva Verde. A blustery spring storm descends, drenching the forest. We venture out anyway, and find that the storm has grounded a large flight of Eastern Kingbirds and Scarlet Tanagers. In just the trees that encircle us, we count at least 50 of the brilliant male tanagers. The green females are much harder to detect in the confusion of leaves, although we manage to find a couple. (In many of the passerines, the males migrate a week or two before the females, and that may be happening with these tanagers.)


In mid-afternoon the storm finally lifts, and migrating Swainson's Hawks immediately take to the skies, rising by the hundreds from the surrounding forest. I expect that the tanagers and kingbirds will lift off at nightfall, joining the hawks in the river of birds which wing their way north each spring.


Have you been especially impressed and delighted by one of your encounters with migrant birds? I welcome your comments.

Nightfall in Monteverde Cloud Forest

Night deepens in this Costa Rican reserve, where our tour group has special permission to stay until after dark. Black are the shapes of roosting guans, the silhouette of a forest falcon. A sleepy quetzal stirs. Jupiter and its moons shine overhead. A tarantula hulks inside her burrow.

Fireflies flicker on, first one, then two, and soon constellations of bioluminescent creatures are drifting through the forest. We see hundreds. Their lights gleam blue, green, pale lemon, ivory, pale orange, reddish, white. One pair of tan beetles mates, pulsing light. The stars have slipped to earth.
