Resource Partitioning: Sergio Diaz & Edwin Romero

Resource Partitioning: Sergio Diaz & Edwin Romero
For the resource partitioning assignment, we decided to observe a tree that is located within Harrison Park, in the southwest side of the city. There were three pieces of evidence that would be considered resource partitioning. The first evidence was the great number of markings/scratches along the tree. At first, we thought that these markings were made by humans, but after observing the tree for some time, we realized that many squirrels kept going up and down the tree. The second evidence was a birds nest that was hidden, but after closer observation, we were sure that it was a birds nest. The nest was mostly composed of old leafs and didn't look to be in good condition. We were able to see a bird come within the nest, but we were unable to see the bird go inside. Lastly, we saw small insects at the base of the tree. These insects kept going inside the small cracks/holes that were located at the bottom of the tree. In conclusion, we saw three species: squirrels, birds, and insects. The evidence: markings/scratches, birds nest, and small cracks/holes.
