We are looking for enthusiastic and creative students and postdocs to join the Macaulay Library to pursue questions in behavioral and evolutionary ecology. Are you interested in animal behavior? The evolution of animal signals? The ecological and evolutionary underpinnings of reproductive strategies? The micro- and macroevolutionary consequences of sexual selection? These questions and others can be answered with the archived media in Macaulay Library and other museum collections, and in some cases by field work on birds and other animals. Please see below if you are interested in these topics and would like to join us. We also encourage students interested in curatorial work and public education to join us. Scientific research is increasingly dependent on technology to address these questions, so we encourage engineers and computer scientists to explore these questions with us, too.
We place equal emphasis on doing the research that we love and teaching and training others to become professional scientists and citizens that value science. In addition, students and postdocs in Macaulay Library have opportunities to interact and collaborate with excellent colleagues through our connections to the Cornell Lab of Ornithology and Department of Neurobiology and Behavior, as well as good ties to other Cornell Departments such as Ecology and Evolutionary Biology and Natural Resources.
Opportunities for Graduate Students and Postdocs
Graduate students and postdocs joining Dr. Mike Webster’s “Weblab” are also part of the Department (or Graduate Field) of Neurobiology and Behavior, and spend time on the main campus as well as at the Lab of Ornithology. Students and postdocs conduct research on a diversity of topics falling within the broad outlines described above. Much of this research is field-based, but some projects rely heavily on using the media specimens and other resources of the Macaulay Library. Although most student projects fall within the major research themes of the Weblab and are focused on birds, we are question-oriented and past student projects have included studies of brood parasitism in ducks, alternative reproductive strategies in sunfish, and even conservation genetics of wild sheep and plants. Contact Mike to learn more.
Opportunities for Undergraduates
We welcome motivated undergraduates interested in obtaining research experience. New students joining the lab are often mentored by a graduate student or postdoc to work on a project. Students often earn course credit for their work. Students who have experience in the lab and show exceptional promise can conduct their own independent research projects. These projects are developed in consultation with the mentor and Mike and often fulfill the requirements of a senior honor’s thesis. Students have also published their work!

Hummingbird Song Evolution
We are seeking an enthusiastic and hard-working undergrad to collaborate in a project on the evolution of learned vocal signals in hummingbirds at the Lab of Ornithology. The study is part of a broader project that aims to understand the macroevolutionary consequences of vocal learning in birds. The primary role will be to assist on the analysis of song structure of several hummingbird species from field recordings. The student will gain experience in the use of specialized software as well as in methods for characterizing and quantifying the structure of animal vocalizations. The student will also have the opportunity to participate in further stages of research including data analysis and interpretation. If interested, send an email to Marcelo Araya-Salas.
Evolution of Male-like Female Hummingbirds
In most species of hummingbird males are much more colorful than females. In some species, however, only some of the females are less ornamented, while others are identical to males in coloration. This pattern is rare among animals and is difficult to explain using typical hypotheses for animal ornamentation. We use a variety of methods including photo analysis, behavioral, and physiology studies to identify the selective underpinnings behind the male-like female phenomena. Graduate student, Jay Falk, is looking for an assistant to aid in photo analysis to measure degree of ornamentation in female hummingbirds. If interested, send an email to Jay.
Liz Bergen is a graduate student seeking assistants to analyze video and audio recordings of satin bowerbirds as volunteers or for credit. The satin bowerbird is an Australian songbird with elaborate, sexually selected displays in which a male builds a stick bower, decorates it with colorful objects, and dances to court visiting females. Males compete with each other over bower displays by stealing decorations, destroying bowers, and fighting with other males for ownership. Liz studies how individual bower owners use social information, gained through communication with male and female visitors, to improve their success in mate attraction and male-male competition. Assistants analyze video and audio recordings of social interactions at bowers that have been collected in Australia from September to December by field crew. Once assistants have become familiar with satin bowerbird behaviors through video coding Liz encourages them to develop an independent research project for credit. If interested, send an email to Liz.
Hybridization in Birds
Would you mate with another species? Why do birds sometimes hybridize with other species Hybridization? More like WHYbridization!
Drs. Rusty Ligon and Gavin Leighton are searching for an enthusiastic undergraduate researcher to help collect data and compile a database on hybridization in birds. The ultimate goal is to test how sociality and breeding systems influence macroevolutionary patterns of hybridization across birds. The work would entail extracting data from primary and secondary sources of information on birds, and learning about macroevolutionary methods. They anticipate that the research would require work for a semester, but could be extended into similar and novel projects. Students working on this project will have the opportunity to receive credit for their participation, or apply for supplemental funding (contingent upon a successful, student-written application). If interested please contact Gavin Leighton explaining your interest in the project.
The Why, What, and Where of Communicative Complexity in Birds
Why are some species vocalizing in numerous contexts and situations, whereas others say a couple things and a couple things only? I am looking for an undergraduate researcher to help mine data and construct vocal repertoires along with associated information in birds. The associated information includes ecology, behaviors, and life history traits that we will then use in the evolutionary analysis. The end goal is to utilize evolutionary methods to determine why certain species are especially vocal. The work would entail extracting data from secondary sources of information on birds, and learning about macroevolutionary methods. I anticipate that the research would require work for a semester, but could be extended into independent and novel projects. The undergraduate would be advised by Dr. Gavin Leighton in the Neurobiology & Behavior Department. If interested please contact Gavin Leighton at email@example.com explaining your interest in the project.
Reconstructing the evolution of female and male bird song across songbirds
Bird song is an example of an elaborate trait, like flashy colors and fancy displays of many animals. Such elaborate traits are classically studied in males and are thought to evolve through sexual selection: male songs become more elaborate over evolutionary time to attract females or compete with rival males. But females of many songbird species sing, too! In some songbird species, however, females do not sing. Therefore, a variety of selection pressures (natural, social, and sexual selection) are likely responsible for the evolution of complex songs in females and males. The goal of Karan Odom’s research is to tease apart which of these selection pressures is responsible for elaboration in both male and female song, as well the loss of female song in certain lineages. Such research helps us understand how the fascinating diversity life on this planet evolved!
Karan is seeking students to assist in gathering data from bird song recordings to compare female and male songs across many different songbird species. Daily research will involve measuring features of female and male song using song spectrograms, gathering information from the literature about female song, and scoring associated behaviors from species accounts. Training will be provided to use sound analysis software, to objectively score animal behaviors, and to collect and manage large data sets. Opportunities may also be available for statistical analysis, learning phylogenetic comparative methods, and practice presenting scientific research. If interested, contact Karan Odom.
