Golden Gate Raptor Observatory’S Manual BELIZE RAPTORWATCH MONITORING MANUAL Belize Raptor Research Institute In collaboration with Toledo Institute for Development and the Environment Ya’axché Conservation Trust 3rd Edition Written by Ryan A. Phillips Belize Raptor Research Institute June 2015 Adopted and customized with permission from the Golden Gate Raptor Observatory’s Manual The mission of the Belize Raptor Research Institute (BRRI) is to strive to protect Neotropical raptors in Belize through research, education and partnerships. BRRI conducts long term scientific research to learn about the status and needs of raptors in the wild, while building local capacity, working with policy makers and educating local and international communities about raptor conservation. The Belize Raptor Research Institute (BRRI) is a 501(c)3 non-profit charitable organization founded in 2009 by like-minded conservationists, bird enthusiasts and environmentalists that wanted to assist in learning about Neotropical raptors and their conservation. Raptors globally face many threats and most are considered to be declining in size. Being apex carnivores, raptors play a vital role in ecosystems and are considered key indicator species, as well as flagship and umbrella species. The Belize Raptorwatch Program is a collaborative effort between BRRI, Toledo Institute for Development and Environment (TIDE), the Belize Forest Department and Ya’axche Conservation Trust (YCT). 2 | P a g e Belize Raptorwatch Manual 3rd Edition June 2015 3 | P a g e Copyright 2015 Belize Raptor Research Institute Raptorwatcher’s Manual 3rd Edition, 2015 All rights reserved.

We thank GGRO for their support and usage of their manual. 4 | P a g e Preface Unraveling the Mysteries of Neotropical Raptors Raptors have captivated humans for thousands of years due to their keen senses, hunting capabilities, power, behaviors, complex migrations and key niches in ecosystems. Raptors play critical ecological roles often impacting ecosystems making them keystone and flagship species for conservation efforts. Using raptors as umbrella species in conservation can protect entire ecosystems and all the species that live within that community, due to their low densities, large area requirements, complex migrations and often specialized requirements. The Neotropical region, which spans much of the Americas, holds one of the least understood raptor communities across the globe as basic natural history information is lacking for most species. Research in the Neotropics and other areas indicates that raptors are important environmental indicators and can determine how intact an ecosystem is. Yet as they are facing many threats, such as habitat loss and persecution, the need for their study and protection grows urgent. Before a sound management plan for species preservation can be written and implemented, the species and ecosystems must be studied and understood. Therefore, due to the lack of information for most Neotropical raptor species, research on these species and their ecosystems is the first step in Neotropical raptor conservation and their protection. We strive to learn about raptor ecology, population dynamics, area requirements, habitat usage and threats to inform the scientific community, so that we can produce and implement sound management strategies and action plans, working with collaborators, for the conservation of raptor species in the Neotropics. Protecting and conserving raptors ultimately protects all biodiversity and the species and biological functions, we as humans, rely for our own survival. This Raptorwatch Program will unravel many mysteries we have about raptors in the Neotropical region and will ultimately allow for the conservation of these species as we work closely with locals and partners to achieve our goals. I want to thank you on behalf of the Belize Raptor Research Institute for being part of this critical research and conservation program and your long hours in the field counting raptors as we embark on this journey, to protect biodiversity globally, together. This program has benefited from the support of the Belize Forest Department and collaboration and support of the Toledo Institute for Development and the Environment and Ya’axche Conservation Trust. We are grateful for these key partnerships to reach our mutual goals. Let’s hit the field and count raptors!

It describes in detail the methods, roles and responsibilities, and protocols of the BRRI Raptorwatch Program. As a tool, this manual works best if you read it at least once before your first day of raptorwatching, keeping track of any questions or obscurities, then read it again, cover to cover after you’ve had a few raptor-filled days at the Cattle Landing count-site. Other references that will help you learn hawks are: William S. Clark & Brian K. Wheeler. The Peterson Field Guide to Hawks -- first (1987) or second (2001) edition. Houghton Mifflin Co. Either edition is an excellent synopsis of all aspects of identification of US and Canada species. The second edition has more information, and more current info. Some prefer the color plates of the first edition for their simplicity. Peter Dunne, David Sibley, & Clay Sutton. 1988. Hawks in Flight, First Edition. Houghton Mifflin Co. Dunne is perhaps the greatest wordsmith and pair of eyes we have when it comes to describing raptors in flight. HIF gives a better illustration of how people really learn raptor shapes and behaviors than any other book. Specific for hawk migration sites. Sibley’s illustrations – it’ll amaze you what black and white can show. Peter Dunne, David Sibley, & Clay Sutton. 2012. Hawks in Flight, Second Edition. Houghton Mifflin Co. An entirely new presentation of the basic hawkwatching material as soon through the eyes of three Cape May. Dunne’s precise and creative prose, combined with Sibley’s art make this a critical and cutting edge book for hawk migration students. An excellent book for every starting-out hawkwatcher. Jerry Liguori. 2005. Hawks from Every Angle. Oxford University Press. An excellent tool for advanced raptor migration students. The author has been a hawk counter at Cape May, NJ, and the Goshutes Mountains of Nevada. His critical eye and photographic talents have made his articles for Birding magazine among the best explanations of raptor plumages. HFEA is useful for learning how to “see” and evaluate hawks.. Jerry Liguori. 2011. Hawks at a Distance. Oxford University Press. Ligouri surpassed his first book with this treatment. Although the two books work well in partnership, HAAD is a tighter, more-polished treatment of some of the same material. It has many more photos, and is published in a smaller more transportable format. Although the emphasis is on what we might call “hawkdots,” the introductory material on each species includes the best basic ID info in one place I ever seen. An excellent book for every advanced hawkwatcher. David A. Sibley. 2002. Sibley’s Birding Basics. Knopf. A brilliant and readable handbook on aspects of identification (what most books don’t tell you). It includes info on molt, behavior, field marks, gestalt. This is a gem of a book for learning the art and background of bird identification. Brian K. Wheeler. 2003. Raptors of Western North America. Princeton University Press. Wheeler downloaded his raptor brain and gave us this brick (544 pp.) and its Eastern counterpart. What’s great? The photos. Many many variations on one species. What’s good? Practical advice about approaching raptors and their biology, and incredible detail on plumages and ranges. What’s not as good? Incredible detail on plumages and ranges. What’s not good as of late 2012? This book is hard to find for less than $100, and is more library tome than field guide. Crossley, Richard, Jerry Liguori, & Brian Sullivan. 2013. The Crossley ID Guide - Raptors. Princeton University Press. Cutting edge doesn’t necessarily work for everyone, but this photo-shopped rapto-rama is worth a long look. Crossley is making a name for himself by cramming many images of one bird species onto one page, or across a 2-page spread. The result, he states, is hawks how you will see them, in context, against a backdrop of field, forest and sky.

  • Field Identification of the Field Identification of the Field
    TOPICS IN IDENTIFICATION he Solitary Eagle ( Harpyhaliaetus solitarius ) is a large raptor that is closely related and similar in adult and immature plum- Tages to the black-hawks in the genus Buteogallus (Lerner and Mindell 2005). It is a rare and very local resident in a variety of wet and dry forested hills and highlands from northern Argentina to northern Mexico (del Hoyo et al. 1994, Ferguson-Lees and Christie 2001). The species has been collected in Mexico not far from the Texas border (see Discussion, pp. 72 –73), so it is possible that it has occurred in the ABA Area. The handful of specimens and nest records of this eagle are from 700 to 2,000 meters above sea level (Brown and Amadon 1968). FFiieelldd IIddeennttiifificcaattiioonn ooff tthhee SSOOLLIITTTAAARRRYYY EEAAAGGGLLLEEE Nevertheless, sightings of this eagle are occasionally reported from lowland tropical rain forest, e.g., at Tikal, Guatemala (Beaver et al. 1991) and the Tuxtlas Mountains of south - William S. Clark ern Veracruz, Mexico (Winker et al. 1992). The species has been reported on some pro - 2301 South Whitehouse Circle fessional bird tours at such lowland sites as Palenque and the Usumicinta River in south - Harlingen, Texas 78550 ern Mexico.

  • Estimations Relative to Birds of Prey in Captivity in the United States of America
    ESTIMATIONS RELATIVE TO BIRDS OF PREY IN CAPTIVITY IN THE UNITED STATES OF AMERICA by Roger Thacker Department of Animal Laboratories The Ohio State University Columbus, Ohio 43210 Introduction. Counts relating to birds of prey in captivity have been accomplished in some European countries; how- ever, to the knowledge of this author no such information is available in the United States of America. The following paper consistsof data related to this subject collected during 1969-1970 from surveys carried out in many different direc- tions within this country. Methods. In an attempt to obtain as clear a picture as pos- sible, counts were divided into specific areas: Research, Zoo- logical, Falconry, and Pet Holders. It became obvious as the project advanced that in some casesthere was overlap from one area to another; an example of this being a falconer working with a bird both for falconry and research purposes. In some instances such as this, the author has used his own judgment in placing birds in specific categories; in other in- stances received information has been used for this purpose. It has also become clear during this project that a count of "pets" is very difficult to obtain. Lack of interest, non-coop- eration, or no available information from animal sales firms makes the task very difficult, as unfortunately, to obtain a clear dispersal picture it is from such sourcesthat informa- tion must be gleaned. However, data related to the importa- tion of birds' of prey as recorded by the Bureau of Sport Fisheries and Wildlife is included, and it is felt some observa- tions can be made from these figures.

  • Raptor Migration in the Neotropics: Patterns, Processes, and Consequences
    ORNITOLOGIA NEOTROPICAL 15 (Suppl.): 83–99, 2004 © The Neotropical Ornithological Society RAPTOR MIGRATION IN THE NEOTROPICS: PATTERNS, PROCESSES, AND CONSEQUENCES Keith L. Bildstein Hawk Mountain Sanctuary Acopian Center, 410 Summer Valley Road, Orwigsburg, Pennsylvania 17961, USA. E-mail: [email protected] Resumen. – Migración de rapaces en el Neotrópico: patrones, procesos y consecuencias. – El Neotró- pico alberga poblaciones reproductivas y no reproductivas de 104 de las 109 especies de rapaces del Nuevo Mundo (i.e., miembros del suborden Falconides y de la subfamilia Cathartinae), incluyendo 4 migrantes obligatorios, 36 migrantes parciales, 28 migrantes irregulares o locales, y 36 especies que se presume que no migran. Conteos estandarizados de migración visible iniciados en la década de los 1990, junto con una recopilación de literatura, nos proveen con una idea general de la migración de rapaces en la región. Aquí describo los movimientos de las principales especies migratorias y detallo la geografía de la migración en el Neotrópico. El Corredor Terrestre Mesoamericano es la ruta de migración mas utilizada en la región. Tres especies que se reproducen en el Neártico, el Elanio Colinegro (Ictina mississippiensis), el Gavilán Aludo (Buteo platypterus) y el Gavilán de Swainson (B. swainsoni), de los cuales todos son migrantes obligatorios, junto con las poblaciones norteamericanas del Zopilote Cabecirrojo (Cathartes aura), dominan numérica- mente este vuelo norteño o “boreal”. Cantidades mucho menores de Aguilas Pescadoras (Pandion haliaetus), Elanios Tijereta (Elanoides forficatus), Esmerejónes (Falco columbarius) y Halcones Peregrinos (Falco peregrinus), ingresan y abandonan el Neotrópico rutinariamente utilizando rutas que atraviesan el Mar Caribe y el Golfo de México. Los movimientos sureños o “australes” e intra-tropicales, incluyendo la dispersión y la colonización en respuesta a cambios en el hábitat, son conocidos pero permanecen relativamente poco estudiados.

  • Codistributed Lineages of Feather Lice Show
    CODISTRIBUTED LINEAGES OF FEATHER LICE SHOW DIFFERENT PHYLOGENETIC PATTERNS A Dissertation by THERESE ANNE CATANACH Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Nova J. Silvy Co-Chair of Committee, Robert A. McCleery Committee Members, Jessica E. Light Julio Bernal Head of Department, Michael P. Masser August 2017 Major Subject: Wildlife and Fisheries Sciences Copyright 2017 Therese A. Catanach ABSTRACT Recent molecular phylogenies have suggested that hawks (Accipitridae) and falcons (Falconidae) form 2 distantly related groups within birds. Avian feather lice have often been used as a model for comparing host and parasite phylogenies, and in some cases there is significant congruence between them. Using 1 mitochondrial and 3 nuclear genes, I inferred a phylogeny for the feather louse genus Degeeriella (which are all obligate raptor ectoparasites) and related genera. This phylogeny indicated that Degeeriella is polyphyletic, with lice from falcons and hawks forming 2 distinct clades. Falcon lice were sister to lice from African woodpeckers, while Capraiella, a genus of lice from rollers lice, was embedded within Degeeriella from hawks. This phylogeny showed significant geographic structure, with host geography playing a larger role than host taxonomy in explaining louse phylogeny, particularly within clades of closely related lice. However, the louse phylogeny broadly reflects host phylogeny, for example Accipiter lice form a distinct clade. Unlike most bird species, individual kingfisher species (Aves: Alcidae) are typically parasitized by 1 of 3 genera of lice (Insecta: Phthiraptera). These lice partition hosts by subfamily: Alcedoecus and Emersoniella parasitize Daceloninae whereas Alcedoffula parasitizes both Alcedininae and Cerylinae.

  • South East Brazil, 18Th – 27Th January 2018, by Martin Wootton
    South East Brazil 18th – 27th January 2018 Grey-winged Cotinga (AF), Pico da Caledonia – rare, range-restricted, difficult to see, Bird of the Trip Introduction This report covers a short trip to South East Brazil staying at Itororó Eco-lodge managed & owned by Rainer Dungs. Andy Foster of Serra Dos Tucanos guided the small group. Itinerary Thursday 18th January • Nightmare of a travel day with the flight leaving Manchester 30 mins late and then only able to land in Amsterdam at the second attempt due to high winds. Quick sprint (stagger!) across Schiphol airport to get onto the Rio flight which then parked on the tarmac for 2 hours due to the winds. Another roller-coaster ride across a turbulent North Atlantic and we finally arrived in Rio De Janeiro two hours late. Eventually managed to get the free shuttle to the Linx Hotel adjacent to airport Friday 19th January • Collected from the Linx by our very punctual driver (this was to be a theme) and 2.5hour transfer to Itororo Lodge through surprisingly light traffic. Birded the White Trail in the afternoon. Saturday 20th January • All day in Duas Barras & Sumidouro area. Luggage arrived. Sunday 21st January • All day at REGUA (Reserva Ecologica de Guapiacu) – wetlands and surrounding lowland forest. Andy was ill so guided by the very capable REGUA guide Adelei. Short visit late pm to Waldanoor Trail for Frilled Coquette & then return to lodge Monday 22nd January • All day around lodge – Blue Trail (am) & White Trail (pm) Tuesday 23rd January • Early start (& finish) at Pico da Caledonia.
