Observation #5
Breaking news in the Cottonwood Park today! The town filled up the pond! Right away I could see the increase of biodiversity in the area. When I arrived, I could hear several deep croaking noises. I hypothesized that the organisms responsible for the sound were frogs. After hunting around the waters murky edges for a while, Danika (my partner ecologist) and I sighted a tiny specked frog. The frogs back was dark green and spotted and it blended in extremely well in the water. This helps them to camouflage into the water, similar to how the birds have darker wings and lighter underbellies. Besides the frogs, there were many types of birds in the area such as Starlings, Robins, Chickadees, and the small song birds. These organisms were feeding on the biotic factors in the area such as the bugs present in the water. With the increase in temperature, I have noticed the increase in the activity of the birds in the park. Instead of just sitting in the tree tops like they used to, they are flying around and searching for food along the waters edge. This creates intensified interspecific competition between the biotic factors in the ecosystem for survival needs. They all need the five key components in order to survive, and with the increase in population, it makes it harder to receive these necessities. I am so excited that the pond filled up because this makes my area much more interesting and diverse!
