Transcript of Birds
& Summer Carrion Purpose What time of the day do birds vocalize the most (daylight or sunset) and why? The purpose of this research is to understand why birds vocalize and what time of the day they are most active. This research will benefit other researchers, birdwatchers, and organizations who want to better understand birds. According to Audobon (2009), the best time to see birds active is earlier in the morning.
Birds have a diurnal routine , this means that they are active during the day time rather than at night (Amazon, 2013).
Birds vocalize for many reasons, like to: alarm, state location, or attract mates (Cornell University, 2007) Hypothesis If we observe birds vocalizing at different times of the day, then we believe that the birds will vocalize more during the day than during the evening, because birds are most active during early morning (Audubon, 2009). Bibliography Do birds vocalize most in green lands or urban areas?
Do the pitch of the bird's vocalization change as they get older?
What is the wavelength (how far it travels) of a bird's call? Our data supported our hypothesis, birds are more active during the day than in the evening/night. There are multiple reasons why this is what it is. One of the reasons is because they have a diurnal routine. Another reason is that birds are more active during the first two to three hours of the morning (Conrad, 2013). In the morning, birds have to find food. When they do they usually contact other birds using contact calls to conveying information about the food. tampa.cbslocal.com runwithjill.blogspot.com - www.icgov.org Studying the basics: Where to look.

Step 2: Go out any day during a sunset or daylight to a local park or public place
Step 3: Stay at one spot at either a park or a public place for a few minutes
Step 4: Record time that birds chirp/call
Step 5: Complete 3 trials for both sunset and daylight observations
Step 6: Compare and analyze results

Student Research Conference
June 9-12, 2012 Sources of Error A possible source of error could be that I miscounted the number of bird calls in each recording. This could have affected my data and results by showing the incorrect number of bird calls in each recording.
Another source of error could be that I started the recording late and didn't recording from the beginning of the bird calls. This could have affected my data and results by showing the incorrect number of bird calls. Claim, Evidence, Reasoning Birds vocalized the most during the daylight than during the sunset. According to the data I collected, the average showed that during the sunset the birds called for about 1463 times, yet during the daylight the birds called for about 1905 times. This shows that birds are active the most during the daylight and during the sunset. According to Audobon (2009) the best time to see birds active is “earlier in the morning”. This is because during the morning, birds have to wake up and go find food, so they call to each other (other family members) to tell them about food locations as well as their location. Sometimes, along their way they could also encounter predators, so it would cause them to call to others about nearby predators by using alarm calls. Also Conrad (2013) stated that birds are “more active during the first two to three hours of the morning”. Data Analysis/ Results Graph Description This graph shows the number of bird vocalizations during daylight and sunset. The x-axis shows the different days that I recorded birds and the y-axis shows the number of bird calls. It is clear that during the daylight birds are more active than during the sunset.
