A Case of a Warbler Eating Berries [resource folder]

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 questioning skills in students.

Editorial Feedback	9/22/12 - the revised file is ready to be published after correcting a few small typographic errors. Because the revised file is a pdf, I am uploading the most recent document in Word format with edits in red. Please correct file with additional photo of berries. Kathy 9/10/2012 - file was updated to include photo of berries. file was e-mailed to me by author. Andrea ----- Overall the reviewers liked this exercise and recommended it be accepted with minor revisions. The following are comments of one reviewer (1-6, followed by my comment in 7). The reviewer suggests more on student response in sections III and IV. Please resubmit with revisions as soon as possible or by the end of July. Change "Author Submission Status" to Submit Revisions. 1. I noted a couple typos you could correct: in Learning Objectives, the fourth line has "thos" (missing an "e" & in IV Classroom Management, second paragraph I think you want "effectIVE" 2. It would seem that students would have difficulty recognizing that the berries are coated with wax. Sometimes a photo (unlike touching the berries) won't convey all the needed info to the viewer. Is there a good "work-around" to this problem, or do students jump to it easily? 3. Would it be interesting to pose questions about the evolutionary significance of wax coating on berries? If most birds can't digest (and are presumably unlikely to eat/disperse the fruits), what purpose(s) does wax serve? 4. Could you provide a few suggestions of what students do, and just as importantly, don't ask (but should)? 5. I really like the flow of observe/note carefully/pose question in parts I and II. However this flow isn't the same in Parts III and IV...could you adjust the presentation here to make it more clear how the activity unfolds? 6. Would it be possible to suggest how a student, and the Instructor, will know that a student really has improved his/her observational skills? Such immediate feedback is quite useful & important. Perhaps another photo as a follow-up? 7. After Part IV it is confusing to have roman numeral II for Objectives of the Case, followed by another roman numeral IV for Classroom Management. The sections should have consecutively higher numbers.
