Undergraduates' Advisor
Ivan's interests focus on ecology and conservation. In his thesis, he identifies bird species nesting in coffee plantations and analyzes potential reproductive patterns associated with these agroecosystems. He is currently working as an intern at the Corporación para el Desarrollo de Caldas, in the Conservation Lands Management area of CHEC.
Jonathan’s research focuses on how predation by mesopredators may have influenced the evolution of egg coloration in tinamous.
Co-advised with Dr. Victor Hugo García-Merchan
Esteban is interested in testing the drivers of diversity in the nest types of passerine birds, specifically in the family Thamnophilidae.
Former Students | Congratulations, Biologists!
Co-advised with Maria Elisa Mendiwelso M.
Jonathan is interested in ornithology, evolutionary biology, and avian ecology, particularly in the processes that have shaped the evolution of reproductive traits. His undergraduate thesis focused on how ecological factors, such as predation, habitat structure, and nesting strategies, influence the evolution of eggshell coloration and functional properties in birds of the family Caprimulgidae.
Co-advised with Dr. María Fabiola Ospina
Sarah is interested in the foraging ecology of hummingbirds. For her thesis, she studied the Buffy Helmetcrest (Oxypogon stuebelii), an endemic and threatened species, using focal observations and mist nets to collect pollen.
2022 Winner François Vuilleumier Fund For Research on Neotropical Birds (NOS)
Project supported by the Sociedad Caldense de Ornitología and Red de Aviturismo de Caldas
Currently, she is a Fellow in the Tropocal Paleoecology Lab at STRI, Panamá.
Co-advised with Dr. Paul David Alfonso Gutiérrez
Juan Felipe León is interested in bird diversity. In his thesis, he studied the effect of vegetation cover on the selection of nesting sites of a bird community in an agroforestry system
Co-advised with Dr. Carlos Daniel Cadena
Maria Elisa is interested in the evolution of color diversity in birds' eggs. In her undergraduate thesis, she explored the drivers of variation in UV Reflectance.
2022 Winner François Vuilleumier Fund For Research on Neotropical Birds (NOS)
She published her thesis in the Proceedings of the Royal Society B Link
Currently, she is an Avian ecology intern at Archbold Biological Station, monitoring the Florida Scrub-Jay.
Co-advised with Dr. Héctor E. Ramírez-Chaves
Daniel is fascinated by birds' patterns of biodiversity. For his undergrad thesis, he explored the biogeographical affinities of bird communities in Caldas.
Co-advised with Dr. Jenny M. Muñoz Zapata
Deivy is interested in species behavioral interactions. In his undergraduate thesis, he studied changes in the structure of mixed bird flocks along a habitat fragmentation gradient in the middle Magdalena, Caldas.
Laura is interested in birds' ecology. For her undergraduate thesis, she studied the breeding biology of the Andean-cock-of-the-rock (Rupicola peruvianus) along its distribution in the Andes.
She published her thesis in the Journal of Natural History Link
