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.

Marismas Nacionales Biosphere Reserve and Birds In northwest Mexico, Marismas Nacionales, an extensive estuarine system, it has been historically recognized for its importance for birds, especially waterfowl, shorebirds, herons and coastal birds like gulls and terns (Leopold, 1959; Morrison et al., 1994; Ortega-Solís, 2011). -
Detroit Audubon Society Annual Program
Spring 2009 www.detroitaudubon.org Volume 2009, Issue 2 Detroit Audubon Society Annual Program - March 28th The 2009 Annual Program will take place on Saturday, March 28th at the Southfield Parks and Recreation building in the Southfield Civic Center. This year’s program will feature a morning field trip to Carpenter Lake, live animals and lessons on animal life and nature photography. The day begins with a bird walk and tour of the new Carpenter Lake Nature Preserve. Mary Carlock, Southfield naturalist, will give an overview of the history and vision for the development and discuss what is planned for the future. At the Parks and Recreation Building, just in time for spring, Becky Johnson from the Detroit Zoo is going to present a program detailing the metamorphosis of amphibians. Then Beth Duman will show her collection of Michigan snakes and discuss their natural history. Our annual membership meeting will be held during the lunch break to inform members of the state of DAS and to discuss programs in progress and plans for new programs. After the break, Joe Rogers will present his program on raptors, hawks and owls found in Michigan. Joe will have several live birds to display. The last session of the day will be devoted to the rapidly advancing field of digital nature photography. Make every effort to attend the program this year. Space is limited, so send in your registration soon. We have tried to keep the fees low and have a great family rate, however, we suggest infants and toddlers not come.

Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review. -

The following Technical Committee meetings were devoted in part or total to working on the Bird Conservation Plan: Tucson, June 11-12, 2004; Guaymas, October 19-20, 2004; Tucson, January 26-27, 2005; El Palmito, June 2-3, 2005, and Tucson, October 27-29, 2005. Another major contribution to the planning process was the completion of the first round of the northwest Mexico Species Assessment Process on May 10-14, 2004. Without the data contributed and generated by those participants we would not have been able to successfully assess and prioritize all bird species in the SJV area. Writing the Conservation Plan was truly a group effort of many people representing a variety of agencies, NGOs, and universities. Primary contributors are recognized at the beginning of each regional chapter in which they participated. The following agencies and organizations were involved in the plan: Arizona Game and Fish Department, Audubon Arizona, Centro de Investigación Cientifica y de Educación Superior de Ensenada (CICESE), Centro de Investigación de Alimentación y Desarrollo (CIAD), Comisión Nacional de Áreas Naturales Protegidas (CONANP), Instituto del Medio Ambiente y el Desarrollo (IMADES), PRBO Conservation Science, Pronatura Noroeste, Proyecto Corredor Colibrí, Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), Sonoran Institute, The Hummingbird Monitoring Network, Tucson Audubon Society, U.S. -

Birdlife in the Sierra Gorda Biosphere Reserve Mexico
Birdlife in the Sierra Gorda Biosphere Reserve, Mexico "Come and find the feathered treasures of the Sierra Madre" Illustrations by Dana Gardner www.sierragordaecotours.com Introduction The Sierra Gorda Biosphere Reserve, which occupies the northern third of the State of Querétaro, stands out in Mexico, a megadiverse country, as its most ecosystem-diverse protected area. From the oldest semi-desert in the country, enduring for around 65 million years, to the coniferous forests inhabiting the highest ridges of the mountains, life flourishes here. The extraordinary richness in its oak forests, tropical forests, riparian forests along the rivers, and the ever shady cloud forests are all part of our rich natural heritage. All of this houses 2,310 species of vascular plants, 110 mammal species including the majestic jaguar, 134 reptile and amphibian species, one third of the Mexican butter- flies with 800 species, and amongst them a trove of 343 birds that include several endemic and highly threatened species. Itinerary Arrival to Mexico City or Querétaro City, the state capital depending on your chosen flight. 1st day You will meet early with Sierra Gorda Ecotours staff to begin the trip to Sierra Gorda. We will have breakfast at the Magic Town (Pueblo Mágico) of Bernal and continue our route to Pinal de Amoles, a town within the Sierra Gorda. We will head to the community of Cuatro Palos and walk to the lookout point of the Cerro de la Media Luna, a winding path between ancient oak trees to the 2,700 meter high peak. The spectacular landscape is a product of the unique location, and one of the most extraordinary sights of the Sierra Gorda where one can see the transition from the semi-desert to temperate forests. -

The Diets of Neotropical Trogons, Motmots, Barbets and Toucans
The Condor 95:178-192 0 The Cooper Ornithological Society 1993 THE DIETS OF NEOTROPICAL TROGONS, MOTMOTS, BARBETS AND TOUCANS J. V. REMSEN, JR., MARY ANN HYDE~ AND ANGELA CHAPMAN Museum of Natural Scienceand Department of Zoology and Physiology, Louisiana State University,Baton Rouge, LA. 70803 Abstract. Although membership in broad diet categoriesis a standardfeature of community analysesof Neotropical birds, the bases for assignmentsto diet categoriesare usually not stated, or they are derived from anecdotal information or bill shape. We used notations of stomachcontents on museum specimenlabels to assessmembership in broad diet categories (“fruit only,” “ arthropods only,” and “fruit and arthropods”) for speciesof four families of birds in the Neotropics usually consideredto have a mixed diet of fruit and animal matter: trogons (Trogonidae), motmots (Momotidae), New World barbets (Capitonidae), and tou- cans (Ramphastidae). An assessmentof the accuracyof label data by direct comparison to independentmicroscopic analysis of actual stomachcontents of the same specimensshowed that label notations were remarkably accurate.The specimen label data for 246 individuals of 17 speciesof Trogonidae showed that quetzals (Pharomachrus)differ significantly from other trogons (Trogon) in being more fiugivorous. Significant differences in degree of fru- givory were found among various Trogonspecies. Within the Trogonidae, degreeof frugivory is strongly correlated with body size, the larger speciesbeing more frugivorous. The more frugivorous quetzals (Pharomachrus)have relatively flatter bills than other trogons, in ac- cordancewith predictions concerningmorphology of frugivores;otherwise, bill morphology correlated poorly with degree of fiugivory. An analysis of label data from 124 individuals of six speciesof motmots showed that one species(Electron platyrhynchum)is highly in- sectivorous,differing significantlyfrom two others that are more frugivorous(Baryphthengus martii and Momotus momota). -
21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection.
