Environmental Science Bird Song Experiment Analysis
Environmental Science Bird Song Experiment Analysis
Instructions:
Kindly read and follow the below instructions carefully to complete and fill out the attached file, which titled “Bird Song Data Sheets”
Lab Objectives:
- Write hypotheses
- Collect data to address hypothesis
- Form conclusions based of collected data
Equipment:
The attached (Bird Song Data Sheets)
Stopwatches or watches with second hand
Binoculars (as many as we have)
Clipboards
Introduction:
Birds sing to defend territories, attract mates, and send warnings. Parent birds often teach their songs to their offspring. Because song plays such an essential role in bird behavior, scientists have been concerned about the effects of urbanization on bird song. Urban noise could overwhelm bird song and disrupt bird behavior. However, birds might also alter their song pitch, frequency or duration to overcome anthropogenic noise (such as cars). Today we will observe bird song near roads with heavy traffic and away from roads to see if birds alter song behavior in the presence of human noise.
Please do that in at least two different locations
Building Hypotheses:
Scientists write hypothesis as educated guesses about what causes something to occur or about why something occurs. Often, these are written as “if, then” statements. For example, if birds are closer to anthropogenic noise, then they will produce less offspring.
Write a hypothesis as an if, then statement to relate anthropogenic noise to bird song duration and frequency.
Bird Song Duration:
Bird Song Frequency:
Compare your hypotheses with your neighbor’s.
Hypotheses must be testable, falsifiable and repeatable. So let’s test our hypotheses!
Bird Song Observations:
Stand or sit in a location for 15 mins. Each time you hear a bird song, record how long the song continues. If there is a break from more than 2 seconds, we will consider it a new song. Repeat this four times, moving around your sample location each time.
Data Compilation:
When you are done taking data, return to the lab (or stay outside!) and enter the data in a spreadsheet. Use the example in the word file to guide you formatting.
