I was out on the cliffs above Grand Junction in Western Colorado on a Spring day. After a time, others that were there left and as it got quieter one could hear all the birds. There Mourning Doves calling and they got louder to where you mostly just heard the coo-coo-coo at the end of their call. So that was going like a bass phrase and there were Cassin's Finches filling in with a pretty melody. Then one Canyon Wren cut loose with its call over the top of it all and the whole composition was washed over me. Wonderful. After a time I could hear some others coming up, the sounds faded and it was gone. Happy was I to have been there.
