The year 2019 was yet another year chocked full of action-packed adventures and amazing experiences. I spent half the year in the incredibly beautiful and diverse country of Colombia guiding at Parque Nacional Natural Tatamá… More
The full moon illuminates a mountainous landscape of forest and cow pastures. Wind whistles through the treetops and cold air cuts through our jackets. It is 11:50 PM on New Year’s Eve and our eyes lock onto the eye-shine of a Dusky Nightjar. In ten minutes, we hope to call this species our first bird of 2018. As the clock strikes 11:59, the eye-shine abruptly vanishes into the darkness. We cry out in disappointment, but are determined to re-find the bird. With an early morning of work ahead of us, we desperately search for the bird so we can snag both our first bird of the year and a few hours of sleep. My partner in this mission is fellow bird bander and Coloradan, Holly Garrod, who is visiting the Madre Selva banding station here in the highlands of Costa Rica. After ten minutes of scouring the landscape, we finally relocate the endemic nightjar hawking for insects in the top of a swaying tree. With a sigh of relief, we turn in for the night.
Before the first rays of sunlight, I emerge from beneath my warm blankets. Accompanied by Holly, and my coworker, Steve Dougill, we pull on rubber boots and head out to set mist nets in the cloud forest behind the house. On behalf of Costa Rica Bird Observatories and their avian monitoring efforts, we are literally preparing to ring in the New Year. As the nets unfurl, birds begin vocalizing. First, I hear the ascending whistle of a Ruddy-capped Nightingale-Thrush. Next, a pair of Black-cheeked Warblers flit across the trail. In quick succession, I hear the calls and songs of a Mountain Thrush, Gray-breasted Wood-Wren, Ochraceous Wren, Large-footed Finch, Black-faced Solitaire, Lesser Violetear, Collared Redstart, Barred Forest-Falcon, and Spotted Wood-Quails. This strong predawn chorus is a good predictor that our morning of mist netting will be productive.
Across six hours, we capture and process 31 individuals with 20 represented species. For Steve and me, this is one of our best days of ringing in Costa Rica yet, and we are both immensely grateful for this opportunity to contribute to the research on the many regional endemics, as well as all the other spectacular residents and migrants of Madre Selva.
Today was certainly an excellent way to kick off 2018. Happy New Year everyone!!!
While our current position with Costa Rica Bird Observatories is primarily based out of the highlands, Steve and I also have the privilege of working on the Caribbean Coast for several days each month. Compared to the cold, wet, and windy highlands, the Caribbean’s warm weather is a nice change, even though tropical rainstorms are prevalent. Even more so, the birds of this region are entirely different. From Madre Selva (our highlands base near San Isidro), we descend the mountain towards the Caribbean coast. After a series of bus rides and a boat trip, we arrive in Tortuguero, a small beach town only accessible by river.
Tortuguero means “The Land of Turtles” in Spanish, and the beach here is the Western Hemisphere’s most important nesting site for the endangered Green Turtle. During our first visit to Tortuguero, we were lucky to catch the tail end of turtle nesting season, which ends in November.
We are here specifically to band birds, so we get to work. Over the course of five days, we band at five different locations. Our sites consist of both primary and secondary forests, some near the beach and some along rivers. During this banding cycle at Tortuguero, we capture a nice variety of birds. For the resident birds, we capture Bronzy Hermit, Stripe-throated Hermit, Long-billed Hermit, Green-breasted Mango, Rufous-tailed Hummingbird, American Pygmy Kingfisher, Streak-headed Woodcreeper, Boat-billed Flycatcher, Yellow-bellied Elaenia, Red-capped Manakin, White-collared Manakin, Checker-throated Antwren, Chestnut-backed Antbird, Western Slaty-Antshrike, Clay-colored Thrush, White-breasted Wood-Wren, and Olive-backed Euphonia. As well, we capture some overwintering migrants from North America. These include, Wood Thrush, Swainson’s Thrush, Gray Catbird, Red-eyed Vireo, Prothonotary Warbler, and Northern Waterthrush.

In early November, I packed my bags and migrated south to Costa Rica. Leaving behind frigid temperatures in Colorado, I arrive in Costa Rica ready for another winter in the tropics. For three months, I will be banding birds for Costa Rica Bird Observatories. First, I ride a bus up the winding Pan-American Highway to Madre Selva, a field station in the Cordillera de Talamanca. Here in the cloud forest, there is an extremely high density of regional endemics. Beyond the familiar North American migrants, I am bombarded with an exciting new suite of birds. With my coworker, Steve Dougill, we begin to familiarize ourselves with the amazing bird-life of the region.
