Bell Ringer(March 31, 2011): Describe how to use an ethogram.

A look at the behavior of Eastern Gray Squirrels and Prevost Squirrels Mrs. Vroman Canter Middle School 8 th Grade March 31, 2011

Does an Eastern Gray Squirrel Spend more time moving around than a Prevost Squirrel?

Gray Squirrels  Scientific name  Description  Classification  Habitat/range  Diet

Gray Squirrels  Life expectancy  Enemies  Interesting facts about the animal

Prevost Squirrel  Scientific name  Description  Classification  Habitat/range  Diet

Prevost Squirrel  Life expectancy  Enemies  Interesting facts about the animal

Prediction The Eastern Gray Squirrel will move around more than the Prevost Squirrel. I think this to be true because the Gray Squirrel has to gather food and hide from predators while the Prevost Squirrel does not since it lives in a zoo.

Procedures  Use a general ethogram to collect behavioral data on the two species of squirrels.  Using an ethogram mark the behavior of the animal after every 15 seconds for 7 minutes.  Total up the number of behaviors observed at the bottom of the ethogram  CONTIUE TELLING HOW TO COLLECT THE DATA

Procedures continued…  Calculate the precentages  Next step

Results: Eastern Gray Squirrel

 Explain your results in words  The Eastern Gray Squirrel spends most of its time being active by digging and moving.

Results: Prevost Squirrel

 Explain your results in words

Conclusion  My prediction was supported. The Eastern Gray Squirrel was more active than the Prevost Squirrel by 21%. The Prevost Squirrel spend most of its time resting. I think I got these results due to the environment’s of the squirrels. EXPLAIN.
