The most interesting thing that I leaned was that crows use a unique, and somewhat unexplainable communication system that allows them to actually describe a person's appearance and the behavioral characteristics of the person. While on the trip, we learned about the Pacific Wren. The Pacific Wren can be identified by a very short tail. The bird is very small, and occupies the understory of the forest and its floor. They are brown, with darker stripes of color on the tail, wings, and brow. The Pacific Wren is very vocal and has both calls and songs in its repertoire. Dominant male Wrens can be very aggressive, especially during mating season.
Birds are an important part of the ecosystem because they aide gymnosperms and angiosperms in the dispersion of seeds. Without birds, "mother" trees would be competing for resources with their "children".
I also thought the crow communication was pretty awesome. I'd love to see some research into how they communicate.
