Trash and Cooperative Feeding at the Lagoon



Another beautiful day at the Colorado Lagoon today! There was so much trash today because of the rain last week. I picked up 3 pounds myself, when usually I only get about one. Together we collected 36 pounds of trash, keep in mind that this doesn't even include the trash we couldn't reach that was in the water. Which is why I am going to invest on a pair of rain boots, I am so tired of not being able to get my shoes wet. The water quality was not good either, there was a layer of pollution (I can't tell what it was, just unnatural) on top of the water on the side near the golf course.

I saw a california pelican, a snowy egret, and some birds that I still have yet to remember their names. It was breakfast time for all of them and I got to see some cooperative feeding. All three different species with different niches working together to feed themselves and each other... mutualism! The pelican glides over the water to watch the surface of the water as the group of ducks (I don't know the name of) all swim in one direction to "corner" the fishes, and the egret stands on shore to catch fishes that swim nearby. Hopefully all of them got to eat as much as they can.

I am a bit concerned about the water quality of the lagoon after the rain. The Colorado Lagoon is a watershed for Long Beach, and we all know how much trash and pollution there is on the ground in Long Beach. There was a layer of pollution over the water by the golf course, it looked so funky I had no idea what it could be, probably just a combination of chemicals. No more littering! I picked up syrofoam plates today that had peak marks on them, birds are eating them and it will harm them.
