The Search for Food

In Jamaica I saw Cattle Egrets sitting on cattle. They rid the cattle of nasty ticks, while having a good food source. A symbiotic relationship.
 
At the California Academy of Sciences, in Golden Gate Park, I watched Cleaner Shrimp clean other organisms of parasites. Again, a symbiotic relationship.
 
This morning Bob T. and I watched four Egrets follow a couple of River Otters dive for food. The Otters must have been stirring up some fish, or other under-water creatures, and the birds somehow profited from this activity. In my picture the Egrets are following along the shore, waiting for the Otters' next move. While reminded of the Cattle Egrets and the Cleaner Shrimp, I don't see this as a symbiotic relationship.
 
Whatever it was, it provided quite show!
