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

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.
