Instructor: Dr. Peter May, 156 Sage Hall, ext. 8189, e-mail - pmay@stetson.edu. 

Office hours: 8-10,11-12 MW, 11-12 TTh, 1-4 Th, or by appointment.  You are welcome to drop in whenever I’m in my office.

Course schedule: Lecture: 10:00  MW  144 Sage Hall   Lab: 8:00-10:45 TTh   144 Sage Hall

All laboratory periods, aside from those when tests are scheduled, will involve field trips to local sites.  Regular attendance at lecture is expected, and excessive absence will result in loss of points from your final grade. Attendance at field trips is mandatory. Three excused (illness, family emergency) absences from field trips will be allowed, after which subsequent absences will result in loss of points.  We will leave promptly at 8:00, so be here on time.  If you miss a field trip due to late arrival, it is considered an absence from that field trip.

No use of cell phones will be permitted while we are in the field observing birds. 

Textbooks, equipment: The main text is Ornithology, by Frank Gill (3rd edition, 2007, W.H. Freeman and Co.). There will also be some assigned readings from the primary literature.  These readings will be posted on Blackboard as .pdf files (requires Adobe Acrobat reader).

In addition, you will need a field guide to eastern birds (several good ones are available at Amazon or any good bookstore, so I have not ordered them through the campus bookstore), and a pair of binoculars. We'll talk about field guides and choosing binoculars on the first day of class.   Economy-level binoculars can be found for as little as $25 at Wal-Mart, and will suffice, but cheap optics are not of particularly high quality and are not very durable.  With optical equipment, you get what you pay for.  Higher quality binoculars can cost anywhere from around $75 to over $1000.

Course materials will be posted on Blackboard at http://blackboard.stetson.edu/ ).  Some supplementary material will be available on my website at http://www.stetson.edu/~pmay/ .

Course description: Lectures  will cover diverse aspects of avian biology, including anatomy, physiology, evolution, classification, ecology, reproduction, and behavior. Laboratory sessions (field trips) will focus on identification (by sight and sound), taxonomy, natural history, and behavior of local species in their native habitats.

Course requirements: Grades will be determined based on the following components:

     Lecture tests (2), final exam                           40% (12.5% each for during semester exams, 15% for final)
     Lab practicals (identification) (2)                     20%
     Field notes and summaries                                        20%
     Research paper                                            20%

Letter grades will be based on a 60-70-80-90 scale, with a curve applied if dictated by the distribution of scores in the class.  I will give approximate letter grades on each test, but these are not binding. Overall course grades are assigned based on the sum of your scores in all of the above components. Make-up exams will be allowed only in the event of a valid medical or family emergency.  All late work will be penalized at the rate of 10%/day.  Work more than 5 class days late will not be accepted.

Tests: Lecture tests and the final examination will draw on material from both lecture and assigned readings; the laboratory practicals will be based on birds seen and identified by the class during field trips, and will involve identification by sight as well as vocalizations.

Lecture tests will be on Thursday, September 27, and Thursday, November 1. The final exam will be on Wednesday, December 12, from 9-11 a.m.

Identification practicals will be on Tuesday, October 9, and Tuesday, December 4. 

Field notes:  You are expected to keep records of species seen on field trips, as well as observations on which habitats they are observed in, and rough approximations of relative abundance.  These notes will be organized into a field summary at the end of the semester. More specific guidelines on what to do with these observations are attached.

Research paper:  This is a topic-oriented paper (i.e., not a report on a particular species or taxonomic group) that reviews the primary literature on some specific aspect of avian biology.  It should be 8-10 pages long, and include at least 10 primary literature citations.  You are to choose a topic, conduct a literature search, and turn in a list of at  least 10 primary literature references by October 1.  An annotated bibliography and paper outline are due on November 14.  You are required to turn in a hard (printed) copy paper and electronic copy (saved as a Microsoft Word .doc file on disc).

Accomodations: Any student who feels that she or he may need an accommodation based on a disability or medical condition should contact the Academic Resources Center in 101 CUB (386.822.7127 or academicresources@stetson.edu), and then see me to make arrangements based on the recommendations of the Academir Resources Center.

Academic Integrity:  All students are expected to abide by the criteria of the Stetson University Honor System, as specified in the Honor Pledge.  The Honor Pledge and other information about the Honor System can be found at http://www.stetson.edu/honorsystem/.  Any instances of plagiarism, copying, or cheating will be dealt with severely, and will result in at least the receipt of a 0 for that assignment, but may include failure of the course.

We will also cover Taxonomy of Florida birds, emphasizing the distinguishing traits of the Orders and major Families of birds found in Florida.  Because taxonomy includes a lot of terminology, and full lectures on classification tend to be rather tedious to most students, taxonomy will be covered in small sections interspersed with the other topics. Classification principles are covered in Chapter 3, and a summary of the living Orders of birds is found on p. 12.

We will not have time to complete all of these topics by the end of the semester.  If any of the topics listed later in the sequence are of particular interest to anyone in the class, let me know and I will modify the schedule to make sure we cover the topics that are of most interest to you.

REQUIREMENTS FOR FIELD NOTES

 

Time spent in the field and the observations made there constitute the largest time component of this course.  Accordingly, I would like you to keep detailed records of what birds we observe and the ecological context in which they are found.

 

On each trip, you should keep field notes (or oral records on tape/digital recorder) that include the date, the species observed by the class (even if you didn't clearly see each species), the estimated number of individuals of that species observed, and the habitat(s) in which the species was observed.

 

At the end of the semester, you should organize your field records in a manner that efficiently but fully summarizes this information about the biology and phenology of the birds observed.  THE SPECIFIC FORMAT IN WHICH YOU PRESENT YOUR NOTES IS UP TO YOU, but your presentation should include the following:

 

1) Species accounts - for each species observed during the semester, you should include a summary page (or section) including the following information:
   a) the range of dates observed
   b) the specific habitats in which it was observed
   c) some simple measure (as defined by you) of relative abundance
        for example - uncommon - only seen occasionally or in small numbers in appropriate habitat
                             common -  usually seen in small numbers in appropriate habitat
                             abundant - usually seen in large numbers in appropriate habitat
        (This is just an example. Consult any checklist, such as those from National Wildlife Refuge pamphlets or websites, for alternative systems).

    d) Seasonal status of each species: Do field guides or other sources list this species as a summer resident, fall migrant only, winter resident, permanent resident, or some other status (rare, irregular)?  Do your sightings agree or conflict with this published information? In other words, did you observe each species in a time of year when it would be expected here?

 

In all species lists, the sequence of species should be accepted taxonomic order (i.e., in the sequence presented in a typical field guide or checklist - primitive orders first, then more advanced orders: Loons, grebes, Pelicans, Wading Birds, Waterfowl, Rails and Coots, Shorebirds, etc.).  Do not present alphabetical lists of species names.

 

2) Species diversity and habitat.  For each habitat type (i.e., hammock, flatwoods, scrub, agricultural, etc. - you decide on how you wish to classify the habitats, but it should be a comprehensive and biologically meaningful categorization), provide the following information:
  

a) a cumulative list of all species seen in each habitat during the entire semester

  

b) average # of species seen in a particular habitat on each trip (for example, if we saw 12 species in pine flatwoods on Trip 2, 16 species on Trip 8, and 18 species on Trip 12, the average would be (12 + 16 + 18)/3, or 15.3.)

 

Prepare bar graphs of the data from a) and b) comparing each of the habitat types.


c) seasonal trends in diversity:  for each habitat type, did the number of species increase or decrease between the late summer/fall migration/winter periods? 

 

Prepare a graph plotting the number of species seen in each habitat vs.  dates that habitat was visited.

 

Examine these data and graphs and try to explain any obvious trends, and then try explain any patterns in terms of the behavior or biology of the particular species in each habitat.  Informed speculation is welcomed.  Do habitats with highest diversity tend to have more species within most or all taxonomic groups, or just within one or a few?  For example, do habitats with high diversity tend to have more non-passerines, more passerines, or both? How are differences in diversity and seasonal changes in diversity related to the occurrence of individual species and their migratory status?  Are differences in these parameters between habitats primarily due to arrival or departure of migrants, or due to other (perhaps unknown) factors, such as poor observing conditions? 

 


3) Individual trip summaries. 

 

For each field trip, you should provide a list of all species seen (total diversity) and the estimated number (abundance) of each.

 

Prepare a graph plotting total diversity of each trip vs. date to examine seasonal changes in overall diversity.  Be aware that a number of other factors besides seasonal changes might affect the number of species seen on any particular day, such as weather conditions, number of habitats visited on that trip, etc.

 

Can you identify any trends or patterns? Try to explain them in terms of the biology or behavior of the relevant species.

Does total diversity appear to show a consistent change through the semester?  How is total diversity related to the number of different habitats visited on each trip?  How are changes in diversity over the course of the semester related to migratory patterns of individual species? 

 

4) Seasonal changes in overall abundance. Using the data on numbers of individual birds seen, calculate the total number of individual birds (of all species) seen on each trip (total abundance), and average abundance per species (total abundance/total # of species seen on that trip). 

 

Prepare 2 graphs, plotting a) total abundance, and b) average abundance per species vs. date.

 

Do these graphs illustrate any clear trends or changes in bird abundance?  How is this related to species diversity (more species à more individual birds) vs. changes in abundance of individual species?  Do these changes seem to be due to migratory patterns of particular species (i.e., arrival of fall migrants and winter residents), changes in abundance of permanent residents, or both?

 

Preparation of these field notebooks will require a substantial investment of time at the end of the semester.  Try to budget your time accordingly.  If you finish writing your research paper a week or two before the end of the semester, you can devote more of your time to preparation of the notebook once all the field data have been collected.   Keeping your observations well-organized and recorded in a Spreadsheet or Database during the semester will reduce your workload at the end of the semester.

 

You may cooperate in the collection of the data in the field (i.e., one person can keep track of the birds seen and then provide that information to others).  You may also work cooperatively in examining the data for trends and patterns, and discussion of the likely causes of those trends.  However, all written work you turn in (including lists, tables, graphics, etc.) should be your own independent work.   Violation of this policy will be considered plagiarism and treated accordingly.
