Yellow-rumped Warbler (Setophaga coronata coronata) is feeding on Bayberry (Myrica pensylvanica) berries in New York City.
The yellow-rumped warbler exhibits a special adaptation that allows this species to eat bayberries to avoid dependence on and competition for insects.
Urban ecology is quickly becoming a major subdiscipline in ecology and being included in the syllabi of most college-level ecology courses. This field and laboratory exercise is designed to be easily modified for use in any area that has a gradient of human density, from urban to rural. In addition, the exercise is designed to 1) cover major organizational levels in ecology, from organisms to...
This is the resource folder for a photographic case study on the Yellow-rumped Warbler. This bird is unusual among warblers in its ability to eat Bayberry seeds. This ability give is a winter food source that minimizes it's need to migrate affecting the way it interacts with its ecosystem. This case explores this aspect of migratory bird biology while developing observational skills and...
Laboratory exercise to teach undergraduates about factors determining territory size. It begins with dissecting owl pellets and leads students through a series of calculations. A key theme is the ability to make and defend valid estimations.
One of the challenges for teachers without a lab, is how to allow students to observe natural animal behavior directly. The freely available videos by the International Wolf Center are ideal for observation of naturalistic interactions, and last for long enough (5-15 minutes) to enable the practice of different observational techniques. This learning activity introduces novices to the...
