  • 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.

  • Assessing Bird Migrations Verônica Fernandes Gama
    Assessing Bird Migrations Verônica Fernandes Gama Master of Philosophy, Remote Sensing Bachelor of Biological Sciences (Honours) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2019 School of Biological Sciences Abstract Birds perform many types of migratory movements that vary remarkably both geographically and between taxa. Nevertheless, nomenclature and definitions of avian migrations are often not used consistently in the published literature, and the amount of information available varies widely between taxa. Although comprehensive global lists of migrants exist, these data oversimplify the breadth of types of avian movements, as species are classified into just a few broad classes of movements. A key knowledge gap exists in the literature concerning irregular, small-magnitude migrations, such as irruptive and nomadic, which have been little-studied compared with regular, long-distance, to-and- fro migrations. The inconsistency in the literature, oversimplification of migration categories in lists of migrants, and underestimation of the scope of avian migration types may hamper the use of available information on avian migrations in conservation decisions, extinction risk assessments and scientific research. In order to make sound conservation decisions, understanding species migratory movements is key, because migrants demand coordinated management strategies where protection must be achieved over a network of sites. In extinction risk assessments, the threatened status of migrants and non-migrants is assessed differently in the International Union for Conservation of Nature Red List, and the threatened status of migrants could be underestimated if information regarding their movements is inadequate. In scientific research, statistical techniques used to summarise relationships between species traits and other variables are data sensitive, and thus require accurate and precise data on species migratory movements to produce more reliable results.

  • Causes and Consequences of Individual Variation in Animal Movement Allison K
    Shaw Movement Ecology (2020) 8:12 https://doi.org/10.1186/s40462-020-0197-x REVIEW Open Access Causes and consequences of individual variation in animal movement Allison K. Shaw Abstract Animal movement comes in a variety of ‘types’ including small foraging movements, larger one-way dispersive movements, seasonally-predictable round-trip migratory movements, and erratic nomadic movements. Although most individuals move at some point throughout their lives, movement patterns can vary widely across individuals within the same species: differing within an individual over time (intra-individual), among individuals in the same population (inter-individual), or among populations (inter-population). Yet, studies of movement (theoretical and empirical alike) more often focus on understanding ‘typical’ movement patterns than understanding variation in movement. Here, I synthesize current knowledge of movement variation (drawing parallels across species and movement types), describing the causes (what factors contribute to individual variation), patterns (what movement variation looks like), consequences (why variation matters), maintenance (why variation persists), implications (for management and conservation), and finally gaps (what pieces we are currently missing). By synthesizing across scales of variation, I span across work on plasticity, personality, and geographic variation. Individual movement can be driven by factors that act at the individual, population, community and ecosystem level and have ramifications at each of these levels. Generally the consequences of movement are less well understood than the causes, in part because the effects of movement variation are often nested, with variation manifesting at the population level, which in turn affects communities and ecosystems. Understanding both cause and consequence is particularly important for predicting when variation begets variation in a positive feedback loop, versus when a negative feedback causes variation to be dampened successively.

  • Climate Change and Animal Migration
    GAL.MOORE.DOC 5/20/2011 5:33 PM CLIMATE CHANGE AND ANIMAL MIGRATION BY THOMAS T. MOORE∗ Animal migrations are important to the healthy function of many ecosystems. When biotic and abiotic cues are altered by climate change, migrations may be disrupted. Climate change has the potential to disrupt these migrations by altering habitat, changing resource availability, increasing habitat disturbance, changing phenology, and stopping migration. The act of migration (i.e., potentially travelling long distances) causes species to confront a wide range of climatic changes that make adaptation especially difficult. Future research goals should strive to obtain long-term data on migrations and better understand how—and whether—migratory species adapt to changes in climate. Future management techniques should strive to maximize the ability of the target species to adapt to climate change by providing species with more options (e.g., protecting alternative migration corridors) to react to changes in their habitat.

    The effect of altitude on the breeding ecology of the dipper (Cinclus cinclus) Thesis submitted in complete fulfilment of the degree of MSc Ecology (by research) Richard Paul Wilkinson BSc (Hons), PGCE May 2019 Declaration I declare that this thesis is my own work, except where acknowledged, and has not been submitted elsewhere in the same form for the fulfilment of a higher-level degree. Richard Wilkinson May 2019 i Dedications In thanks for the lives of: Jean Thornley 1926 - 2018 Martin John Bickerdyke BSc, MSc, PGCE 1961 - 2018 ii Thesis abstract In many migratory populations, only some individuals migrate each year whereas others are resident; this is known as partial migration. Empirical studies of the causes and consequences of altitudinal partial migration are few, and the costs and benefits of the different life-history strategies involved require further study. In this thesis, I investigate the effect of altitude and other factors on the timing of breeding, reproductive success and parental care in a partially migrant species; the dipper (Cinclus cinclus), a specialised riparian passerine that is thought to be declining in the UK. Most dipper populations comprise partial migrants that move to higher altitudes to breed and sedentary residents at lower elevations, but little is known about the effects of elevational gradients on the life-history traits and reproductive success of these birds. Here, I used mixed effect models to analyse field data from a long-term study population and: (1) examine the effects of altitude, female age and size on lay date, nestling mass, fledging success, number of fledglings and annual productivity; and (2) investigate the effect of altitude and prey availability on parental provisioning rate.

  • Rethinking the Evolution of Seasonal Migration
    Winger Benjamin (Orcid ID: 0000-0002-2095-2020) A long winter for the Red Queen: rethinking the evolution of seasonal migration Benjamin M. Winger*, Giorgia G. Auteri, Teresa M. Pegan & Brian C. Weeks Museum of Zoology and Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA *Author for correspondence (E-mail: [email protected]; Tel.: 1-734-763-3379). ABSTRACT This paper advances an hypothesis that the primary adaptive driver of seasonal migration is maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration is therefore principally an adaptation for geographic persistence when confronted with seasonality – analogous to hibernation, freeze tolerance, or other organismal adaptations to cyclically fluctuating environments. These ideas stand in contrast to traditional views that bird migration evolved as an adaptive dispersal strategy for exploiting new breeding areas and avoiding competitors. Our synthesis is supported by a large body of research on avian breeding biology that demonstrates the reproductive benefits of breeding-site fidelity. Conceptualizing migration as an adaptation for persistence places new emphasis on understanding the evolutionary trade- This is the author manuscript accepted for publication and has undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

Seasonality-induced departures from breeding areas, coupled with the reproductive benefits of maintaining breeding-site fidelity, also provide a mechanism for explaining the evolution of migration that is agnostic to the geographic origin of migratory lineages (i.e.
