Geographic Variation and Species Limits in Middle American Woodnymphs (Thalurania)
THEWILSONBULLETIN A QUARTERLY MAGAZINE OF ORNITHOLOGY Published by the Wilson Ornithological Society VOL. 104, No. 2 JUNE 1992 PAGES 205-388 Wilson Bull., 104(2), 1992, pp. 205-219 GEOGRAPHIC VARIATION AND SPECIES LIMITS IN MIDDLE AMERICAN WOODNYMPHS (THALURANIA) PATRICIA ESCALANTE-PLIEGO ’ AND A. TOWNSEND PETERSON* ABSTRACT.- We analyzed geographic variation in morphology and plumage coloration in male woodnymphs of the genus Thalurunia in Middle America and northwestern South America. Morphometric characters distinguish the disjunct western Mexican populations from populations to the south. Three groups are distinguished by discrete plumage coloration characters. We propose that these groups be recognized as separate species: T. ridgwuyiof western Mexico; T. colombicaof Central America south to western Panama and disjunctly in interior northwestern South America; and T.fannyi ofeastem Panama, western Colombia, and northern Ecuador. Received1 I July 1991, accepted20 Sept. 1991. RESUMEN.-En este trabajo analizamos la variation geografica en morfologia yen patrones de coloration en el plumaje de 10s machos de las “ninfas de bosque” de1 genera Thalurunia de Mesoamerica y noroeste de Sudamtrica. Los caracteres morfometricos distinguen las poblaciones de1 oeste de Mexico de todas las poblaciones de1 sur. Con base en la coloration de1 plumaje, caracteres discretos separan tres grupos. Proponemos que estos grupos Sean reconocidos coma especies distintas: T. ridgwayi de1 oeste de MCxico; T. colombicadesde Centroamerica hacia el sur al oeste de Panama y continuando desputs en el noroeste de Sudamerica; y T.fannyi de1 este de Panama, oeste de Colombia y extremo norte de1 Ecuador. In spite of more than a century of study, patterns of geographic variation and speciation in Middle American birds remain poorly understood. -
Maya Knowledge and "Science Wars"
Journal of Ethnobiology 20(2); 129-158 Winter 2000 MAYA KNOWLEDGE AND "SCIENCE WARS" E. N. ANDERSON Department ofAnthropology University ofCalifornia, Riverside Riverside, CA 92521~0418 ABSTRACT.-Knowledge is socially constructed, yet humans succeed in knowing a great deal about their environments. Recent debates over the nature of "science" involve extreme positions, from claims that allscience is arbitrary to claims that science is somehow a privileged body of truth. Something may be learned by considering the biological knowledge of a very different culture with a long record of high civilization. Yucatec Maya cthnobiology agrees with contemporary international biological science in many respects, almost all of them highly specific, pragmatic and observational. It differs in many other respects, most of them highly inferential and cosmological. One may tentatively conclude that common observation of everyday matters is more directly affected by interaction with the nonhuman environment than is abstract deductive reasoning. but that social factors operate at all levels. Key words: Yucatec Maya, ethnoornithology, science wars, philosophy ofscience, Yucatan Peninsula RESUMEN.-EI EI conocimiento es una construcci6n social, pero los humanos pueden aprender mucho ce sus alrededores. Discursos recientes sobre "ciencia" incluyen posiciones extremos; algunos proponen que "ciencia" es arbitrario, otros proponen que "ciencia" es verdad absoluto.

Anti-Predator Behavior in Birds: Reactions to Raptor Calls
Anti-predator behavior in Birds: Reactions to Raptor Calls Robin Elahi Department of Biology, Northeastern University _____________________________________________________________________________________ ABSTRACT Birds display a number of defense mechanisms against their predators, including camouflage, mobbing, fleeing, and aggregational behavior. I studied the responses of 32 bird species to songbird and raptor calls to see if birds displayed anti-predator behavior in response to raptor calls in comparison with songbird calls. One focus of my study was avian defensive strategies, namely flocking and concealment, so observations took into consideration different conditions: whether the bird was solitary or in a group, and whether it was exposed or hidden in vegetation. A previous study showed that crows could distinguish between raptor calls of their predators and non-predators, so I examined if birds specifically recognized resident raptors, or if they had a general response to resident and non-resident raptor calls. I also attempted to correlate bird size with reaction, specifically to see if smaller birds flew away more often than larger birds due to a greater perceived threat. For each bird or group of birds. I played a songbird call, followed by a raptor call, and timed the raptor call to see how long the bird stayed till it flew away. Birds flew away 27% of the time in response to raptor calls, and only 3% of the time to songbird calls (X² = 16.11, df = 1, n = 26). Birds did not distinguish among resident and non-resident raptor calls, and had nearly equal flight frequencies (X² = 0.48, df =3, n=40). Trends showed that solitary and exposed birds tended to fly more often than birds in groups and hidden birds. -

Its use as a meaningful taxonomic indicator has been defunct for well over a century, as the “warblers” encompass hundreds of thin-billed, insectivorous passerines across more than a dozen families worldwide. This is not itself an issue, as many other passerine names (flycatcher, tanager, sparrow, etc.) share this common name “polyphyly”, and conventions or modifiers are widely used to designate and separate families that include multiple groups. -

Yet, it was still too early to experience the real explosion of bird song, which usually happens after dawn. Then, after 05:30 AM, the chorus started when a vocal Great Kiskadee broke the morning silence, followed by the scratchy notes of two Hoffmann´s Woodpeckers, a nesting pair of Inca Doves, the ascending and monotonous song of the Yellow-bellied Elaenia, and the cacophony of an (apparently!) engaged pair of Rufous-naped Wrens. This was indeed a warm welcome to magical Costa Rica! To complement the first morning of birding, two boreal migrants, Baltimore Orioles and a Tennessee Warbler, joined the bird feast just outside the hotel area. Broad-billed Motmot . Photo: D. Ascanio © Victor Emanuel Nature Tours 2 The Best of Costa Rica, 2019 After breakfast, we drove towards the volcanic ring of Costa Rica. Circling the slope of Poas volcano, we eventually reached the inspiring Bosque de Paz. With its hummingbird feeders and trails transecting a beautiful moss-covered forest, this lodge offered us the opportunity to see one of Costa Rica´s most difficult-to-see Grallaridae, the Scaled Antpitta. -
Costa Rica: the Introtour | July 2017
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. Then there were many www.tropicalbirding.com +1-409-515-9110 [email protected] Page Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 superb reptiles and amphibians, among them Emerald Basilisk, Helmeted Iguana, Green-and- black and Strawberry Poison Frogs, and Red-eyed Leaf Frog.
