SUPPLIES needed for the first week:  

• 4 pairs of binoculars (one for each team)
  

• maps of campus (one for each team)
  

• time budget data sheets

• binoculars, maps, and time budget data sheets as for the first week
  

• 4 cassette tape players
  

• 4 amplified speakers
  

• 4 connecting leads
  

• batteries for cassette players (2 C cells each) and speakers (4 C cells each).

Batteries are stored in the refrigerator in Wilson 317; use a battery tester to check them each time before use.

PROCEDURES

This lab also requires use of equipment outdoors, an invitation for malfunctions!   Students should take responsibility for checking the equipment and getting it ready for use.   In addition, they should learn how to use it.   The students' Lab Manual makes these responsibilities clear.

Preparation by students a week in advance.   During the week before this exercise take a half hour (or more if needed) to have the students get the equipment ready.  

• Students should load batteries into the cassette tape players and the speaker/amplifiers.   (Students should also remove the batteries the week after they are used.)
  

• Students should also learn how to connect the tape-recorder to the speaker/amplifier and how to adjust the volume.  
  

• Students should think about how to design data sheets to collect information on time budgets and responses to playback.   You might want all classes to use the same standardized sheet -- but the students should think about how to design it and perhaps should prepare their own sheet.
  

• Students should also check the binoculars.
  

• Students should learn how to identify mockingbirds!   If your lab is during the summer, note that juvenile mockingbirds (those less than a few months old) have spotted breasts.   For our purposes, focus on adults, not juveniles.
