Stopwatches or watches with second hand
Binoculars (as many as we have)
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
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.
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.
