Encouraging nonprofessionals to participate in ecological research through citizen science programs is a recent innovation and an effective strategy for gathering ecological information across broad geographical areas. In this paper, we demonstrate how reporting field-based observations through eBird, a citizen-based birding and data-recording…

Describes the use of Web technology to create a repository for American bird songs at Northeastern Sate University (Oklahoma). Explains the use of software to translated bird songs into a sonogram, or picture, of what the sounds look like for ornithology students to better learn bird vocalizations. (LRW)

Presents a field formula for calculating speed and flight efficiency of soaring birds. By estimating the size of the bank angle and timing the complete circle, the observer can determine the speed and circling radius on a chart provided. Lift coefficients and flight characteristics of several birds are also discussed. (DH)

Discusses the work of two authors--Lawrence Kilham and Alexander Skutch--who write about birds. Highlights books about birds written by different authors. Contains 23 references. (JRH)

Describes a bird-study and banding activity designed for students in urban and suburban areas. (PEB)

The author explains how he uses the Audubon Christmas Bird Count to teach a laboratory exercise in vertebrate population dynamics. Problems and limitations associated with using these Christmas Counts are also enumerated. Graphs illustrate the material. (MA)

An activity simulating natural selection in which wild birds are predators, green and brown pastry "baits" are prey, and trays containing colored stones as the backgrounds is presented. Two different methods of measuring selection are used to describe the results. The materials and methods, results, and discussion are included. (KR)

Describes studies at winter bird feeders which enhance instruction of ecology at the University of Michigan biological station. Background material is provided for field activities in which black-capped chickadees are observed and for home range determination and population estimate activities. (DH)

Discusses marine adaptations of seabirds, feeding/breeding methods, and their vulnerability to predators. Also considers dangers from new "predators," such as hunting, environmental factors (pollution/pesticides), and loss of natural environments. Future prospects for the survival of these organisms are considered. (JN)

Compares two different methods of educational instruction, both addressing the improvement of pupils in bird species identification skills. Uses hands-on and group-based learning styles with (stuffed) taxidermy specimens and teacher-based slide presentations. Reports an increase in knowledge with both instructional methods but different learning…

Reports findings on research in Red-winged Blackbird territoriality and describes the educational potential of use of similar studies in the classroom. Territorial mapping and observational techniques are explained. (CS)

In these days of increasing concern for the state of the environment and declining biodiversity, it is important that students and teachers come to appreciate the value of life in all its forms. Natural history provides students with an opportunity to understand better how life on the planet interacts, as well as the place and responsibility of…

Two properties of a wing, namely aspect ratio and wing loading, are described and the matrix approach is used to make certain deductions about particular wing plans. Some examples are provided which show how the matrix transformation of one wing plan into another brings about predictable changes in wing properties. (KR)

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…

Presents information on the population density, breeding biology, habitats, and food of the magpie bird ("Pica pica"). Suggests and outlines several student projects that have been beneficial in teaching animal behavior and ecology. These investigations focus on diet, territory size, and food hoarding. (DH)
