Maggie MacPherson presented a poster on the evolution of migrationof Tyrannus flycatchers at this year’s Meeting of the Society of Integrative and Comparative Biology, January 4-8, 2017, New Orleans, Louisiana, USA: macpherson-sicb-2017... continue reading.
Our colleague from the Universidad de Buenos Aires, Diego Tuero, presented the following poster on sexual selection in Fork-tailed Flycatchers (Tyrannus savana) at the 16th Congress of the International Society for Behavioral Ecology (http://www.isbe2016.com/).... continue reading.
From 17 to 20 August 2016, several of us participated in the sixth North American Ornithological Conference (http://naoc2016.cvent.com), held in Washington DC. Three of the posters we presented on various aspects of Fork-tailed Flycatcher ecology are shown below.... continue reading.
How climate affects the timing of bird migration is a key question in the study of migratory bird ecology. One of our colleagues, Maggie MacPherson, a PhD candidate at Tulane University, is modeling how Tyrannus flycatchers track rainfall vs. temperature across the Western Hemisphere.... continue reading.
Over the last several weeks, migratory Fork-tailed Flycatchers (Tyrannus s. savana) have been migrating from their breeding grounds in southern and central South America to northern South America, where they will spend the austral winter.... continue reading.
Last week, one of our collaborators, Emanuel Pérez Bogado, a graduate student in Patricia Capllonch’s lab at the Universidad Nacional de Tucumán, Argentina, saw flocks migrating Fork-tailed Flycatchers in northern Argentina (Tucumán Province).... continue reading.
Light-level geolocator data from Fork-tailed Flycatchers (Tyrannus s. savana) breeding in central Brazil indicate that some flycatchers spend a month (late January to mid-February) in southwestern Brazil, before migrating to northern South America to overwinter (unpub. data). So, from 6-12 February, 2016, Andre Guaraldo and Alex Jahn searched for Fork-tailed Flycatchers in the state of Mato Grosso do Sul in southwestern Brazil, hoping to find a roost at which they could be captured.... continue reading.
From 29 October to 4 November, 2015, a workshop was held on zoonotic disease transmission by migratory birds and bats, funded by the Argentinian Ministry of Education. Attendees included: Patricia Capllonch, Karina Soria, Rodrigo Araoz, Diego Ortiz, Emanuel Perez Bogado, Ezequiel Barbosa (Universidad Nacional de Tucuman), Adrian Diaz, David Vergara, Agustin Quaglia, Tobias Rojas, Ernesto Verga (Universidad Nacional de Cordoba), and Alex Jahn (Universidade Estadual Paulista).... continue reading.
In October 2015, Jesse Lopes, Sebastian Lyons, Shazeeda Ameerally and Alex Jahn spent about 2 weeks in Brasilia, Brazil catching Fork-tailed Flycatchers and monitoring their nests. The region was experiencing strong drought conditions and the birds appeared to be delaying their breeding schedule. We caught several birds (one with a geolocator deployed in 2013) and found over a dozen nests…... continue reading.
Several of us (Maggie MacPherson, Valentina Gómez Bahamón, and Alex Jahn) recently gave talks at the X Neotropical Ornithological Congress (NOC) / XXII Congresso Brasileiro de Ornitologia (CBO).... continue reading.
