After completing three months of intensive avian fieldwork in the Talamanca Highlands and Caribbean Coast, I have a little over a week to burn before leaving the country and am eager to see new landscapes and their associated birds. Below are some photo highlights from this nine-day circuit, which covered the southern foothills, the Pacific coastline including the the Osa and Nicoya Peninsulas, and lastly, the Volcán Arenal.
Note: The bird in the banner photo is a Silver-throated Tanager (Tangara icterocephala).
In this cloud forest landscape rich with regional endemics, Steve and I unfurl nets at first light and work well into the afternoon on a near daily basis. On the rare day off, we go birding and sometimes venture off on short excursions. One morning, we make it to the páramo, 25 kilometers up the highway. Here, we see our first Volcano Juncos and Timberline Wrens, both species only found in this unique sub-alpine habitat of Costa Rica and western Panama.
From our house and headquarters at Madre Selva, I often explore the surrounding forests. While the process of banding birds naturally allows for the up-close and detailed study of individual birds, observing them in their natural habitat is incredibly rewarding and valuable in itself.
Below are a few last images of banding at Madre Selva . . .
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!!!
