Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 A Tropical Birding SET DEPARTURE tour Costa Rica: The Introtour July 15 – 25, 2017 Tour Leader: Scott Olmstead INTRODUCTION This year’s July departure of the Costa Rica Introtour had great luck with many of the most spectacular, emblematic birds of Central America like Resplendent Quetzal (photo right), Three-wattled Bellbird, Great Green and Scarlet Macaws, and Keel-billed Toucan, as well as some excellent rarities like Black Hawk- Eagle, Ochraceous Pewee and Azure-hooded Jay. We enjoyed great weather for birding, with almost no morning rain throughout the trip, and just a few delightful afternoon and evening showers. Comfortable accommodations, iconic landscapes, abundant, delicious meals, and our charismatic driver Luís enhanced our time in the field. Our group, made up of a mix of first- timers to the tropics and more seasoned tropical birders, got along wonderfully, with some spying their first-ever toucans, motmots, puffbirds, etc. on this trip, and others ticking off regional endemics and hard-to-get species. We were fortunate to have several high-quality mammal sightings, including three monkey species, Derby’s Wooly Opossum, Northern Tamandua, and Tayra.

We also enjoyed views of a pair of Rufous-naped Wrens, a vocal Rufous-browed Peppershrike, and the unmistakable Lesson’s Motmot. After breakfast, we took the road to Cartago where a little productive grassland allowed views of a few birds. Then we ascended the Pan-American Highway and, after reaching a higher elevation, we noticed a sudden change in vegetation and humidity; we had entered the cloud forest. A wonderful lunch was accompanied by excellent views of the territorial Fiery-throated Hummingbird and other allies including Talamanca and Volcano hummingbirds. Continuing our birding activities after lunch, we decided to take our chances exloring the highlands, to the antenna road. Reaching the pre-paramo is always a challenge because the weather can change dramatically in a few minutes. But, despite the wind and the humidity, we enjoyed very close views of Volcano Junco. Later, a Peg-billed Finch showed up for seconds, and for a grand finale we had a striking encounter with the Timberline Wren. -

Without the rush to build a large list of species but rather with the intention to get a large amount of good photos while enjoying bird sightings and behavior we had a fantastic time on our trip. We started our trip in Alajuela near San José’s Juan Santamaría International Airport and from there drove across the country, visiting different areas including the Caribbean lowlands in the north with obligatory stops at La Selva Biological Station, Sarapiquí, the Cinchona feeders, and the private Donde Cope nature center. Our time here was fantastic; we had the opportunity to see and photograph birds such as the endemic Coppery-headed Emerald, Black-bellied Hummingbird, Semiplumbeous Hawk, Great Green Macaw, White-tipped Sicklebill, Great Potoo, Spectacled Owl, Violet Sabrewing, Red-headed Barbet, Prong-billed Barbet, Blue-throated Toucanet, Yellow-throated Toucan, Keel-billed Toucan, White- necked Puffbird, Buff-fronted Quail-Dove, Black Guan, Buff-rumped Warbler, and the fabulous Snowcap. Our trip continued to the cloudforest mountains at San Gerardo de Dota at the famous Savegre Hotel, where we managed to record species such as Large-footed Finch, Yellow-thighed Finch, Spotted Wood Quail, Wrenthrush, Hairy Woodpecker, Long-tailed Silky-flycatcher, Black- and-yellow Phainoptila, Golden-browed Chlorophonia, Acorn Woodpecker, Slaty Flowerpiercer, Fiery-throated Hummingbird, Talamanca Hummingbird, Volcano Junco, Timberline Wren, and the most-wanted Resplendent Quetzal. -

ATWELL,* DAWN M. O’NEAL** & ELLEN D. KETTERSON*** Identifying important “migratory species” and the characteristics of their migrations might sound like a simple starting point for efforts to conserve and protect animal migrations. However, migrations are dynamic phenomena that vary over space and time, and migratory behaviors can vary substantially among closely related species, subspecies, races, or populations, and even among individual animals within a single population. The migratory behaviors of populations or individuals can also change rapidly—or be lost entirely—in response to habitat alteration or climate change. These complexities present both challenges and opportunities for initiatives to conserve animal migrations. In this Article, we discuss the concepts of intra-species variation in migration and the sensitivity of migrations to * Ph.D. Candidate in Evolution, Ecology, and Behavior; Department of Biology and Center for the Integrative Study of Animal Behavior (CISAB), Indiana University, Bloomington, Indiana. ** Post-doctoral Research Associate; School of Ecology, University of Georgia, Athens, Georgia. *** Professor of Biology; Department of Biology and Center for the Integrative Study of Animal Behavior (CISAB), Indiana University, Bloomington, Indiana.

That is how I must describe my second Costa Rica Escape tour of 2019. Only two days after our set-departure tour had ended with great results we embarked on a new adventure, following the same birding route, but on a custom tour this time. In the company of fantastic people, who had had previous experience in the country, we focused on a specific list of hoped-for lifers this time but still enjoyed every bird sighting as well mammals and all sort of other creatures such as reptiles, amphibians, and butterflies. Our final bird list included, among many others, sightings of Resplendent Quetzal, Great Curassow, Snowcap, Buffy Tuftedcheek, American Dipper, Streak-chested Antpitta, Spectacled Owl, Black-and-white Owl, Great Potoo, Turquoise-browed Motmot, White- eared Ground Sparrow, Spangle-cheeked Tanager, Long-tailed Silky-flycatcher, Spotted Wood Quail, Northern Barred Woodcreeper, Pale-billed Woodpecker, Silvery-fronted Tapaculo, Great Green Macaw, Coopery-headed Emerald, Golden-browed Chlorophonia, Timberline Wren, Volcano Junco, Fiery-billed Aracari, Scarlet Macaw, Mangrove Hummingbird, Prong-billed Barbet, Red-headed Barbet, Merlin, Black Guan, and Snowy Cotinga. Detailed Report Day 1, Freddo Fresas, La Paz Waterfall, Cinchona Feeders, Virgen del Socorro After ticking Hoffmann’s Woodpecker, Rufous-backed Wren, Great-tailed Grackle, American Yellow Warbler, and White-winged Dove we left our hotel in Alajuela and headed to the Freddo Fresas restaurant on the way to the Caribbean slope. -

(over the presence of a third individual, which we assumed was a female) in the wonderful gardens of the Hotel Bougainvillea were the perfect appetizer of the amazing birds that we were about to see during our Relaxed & Easy Costa Rica tour. These gardens also gave us the opportunity to enjoy the astonishing White-eared Ground-Sparrow and the uncommon Rose- throated Becard. After breakfast, we loaded our bus and started the drive to Cerro de la Muerte, in the Talamanca mountain range. Volcano Hummingbird, Selasphorus flammula . Photo: D. Ascanio Once along the ridge of these mountains, we stopped for lunch in Paraiso Quetzal where we enjoyed views of Talamanca Hummingbird (split from Magnificent Hummingbird). Some of us nailed the Black-and-yellow Silky-Flycatcher and, surprisingly, there was only a single Fiery- throated Hummingbird (on previous tours we have seen various individuals here). We were delighted with territorial Lesser Violetear (split from Green Violetear) and a loose mixed species flock that gave us our first sightings of Ruddy Treerunner, Yellow-winged Vireo, Ochraceous Wren, Black-cheeked Warbler, and Spectacled Redstart. -

The deadly pandemic has affected all of us and we hope that you have managed to stay safe and well. 2020 was to be our 50th anniversary and we had great plans to celebrate this milestone in Reno. It was not to be, but we are very hopeful that we can gather there and celebrate together next August. As we assess our year-end financial balance, the loss of anticipated income from the lack of a conference and expeditions has left us with a net loss of about $20,000. WFO has husbanded its resources well, so while the situation is not dire, we feel it necessary and prudent to ask for your support. It is important for our membership to know that your dues alone do not fully support the publication of our flagship quarterly journal, Western Birds.
