Those who arrived in daylight had time to explore the phenomenal gardens, despite a rain storm. Day 1 - January 30 Optional day-trip to Carara National Park Guides Vernon and Frank offered an optional day trip to Carara National Park before the tour officially began and all tour participants took advantage of this special opportunity. As such, we are including the sightings from this day trip in the overall tour report. We departed the Hotel at 05:40 for the drive to the National Park. En route we stopped along the road to view a beautiful Turquoise-browed Motmot. -
Long-Term Changes in the Bird Community of Palenque, Chiapas, in Response to Rainforest Loss
Biodivers Conserv (2010) 19:21–36 DOI 10.1007/s10531-009-9698-z ORIGINAL PAPER Long-term changes in the bird community of Palenque, Chiapas, in response to rainforest loss Michael A. Patten Æ He´ctor Go´mez de Silva Æ Brenda D. Smith-Patten Received: 18 March 2008 / Accepted: 22 July 2009 / Published online: 6 August 2009 Ó Springer Science+Business Media B.V. 2009 Abstract With increased human populations and subsequent pressure to develop or farm land, the rate of fragmentation of tropical rainforests has accelerated in the past several decades. How native organisms respond to such fragmentation has been the subject of intense study in temperate ecosystems and at several tropical sites in Central and South America, but there has been little study of this phenomenon in Mexico, the country bridging the Neotropics and temperate North America. A reason for this neglect is an apparent lack of long-term data; however, such data can be obtained from ‘‘non-tradi- tional’’ sources, such as birders and tour leaders. We make innovative use of such data, combining them with more traditional data (e.g., museum specimens) to create a record of occurrence for Palenque, Mexico, from 1900 to 2009, including a near-continuous pres- ence–absence record since 1970. We analyzed these data using logistic regression and, importantly, recent statistical advances expressly for sighting records. As recently as the 1960s Palenque’s forest was contiguous with that of Selva Lacandona to the east, but the protected area surrounding the famous ruins is now a forested island. As a result, various species formerly known from the site have disappeared, including species both large (Crax rubra, Penelope purpurascens, and Ara macao) and small (Notharchus hyperrhynchos, Malacoptila panamensis, Microrhopias quixensis, and Pachyramphus cinnamomeus). -

Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J. Collar (2014); 2. -

Environmental Sensitivity Index Guidelines Version 2.0
NOAA Technical Memorandum NOS ORCA 115 Environmental Sensitivity Index Guidelines Version 2.0 October 1997 Seattle, Washington noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION National Ocean Service Office of Ocean Resources Conservation and Assessment National Ocean Service National Oceanic and Atmospheric Administration U.S. Department of Commerce The Office of Ocean Resources Conservation and Assessment (ORCA) provides decisionmakers comprehensive, scientific information on characteristics of the oceans, coastal areas, and estuaries of the United States of America. The information ranges from strategic, national assessments of coastal and estuarine environmental quality to real-time information for navigation or hazardous materials spill response. Through its National Status and Trends (NS&T) Program, ORCA uses uniform techniques to monitor toxic chemical contamination of bottom-feeding fish, mussels and oysters, and sediments at about 300 locations throughout the United States. A related NS&T Program of directed research examines the relationships between contaminant exposure and indicators of biological responses in fish and shellfish. Through the Hazardous Materials Response and Assessment Division (HAZMAT) Scientific Support Coordination program, ORCA provides critical scientific support for planning and responding to spills of oil or hazardous materials into coastal environments. Technical guidance includes spill trajectory predictions, chemical hazard analyses, and assessments of the sensitivity of marine and estuarine environments to spills. To fulfill the responsibilities of the Secretary of Commerce as a trustee for living marine resources, HAZMAT’s Coastal Resource Coordination program provides technical support to the U.S. Environmental Protection Agency during all phases of the remedial process to protect the environment and restore natural resources at hundreds of waste sites each year. -
