I learned recently to identify squirrel alarm calls:

So today walking after dinner I knew right at that sound that the park’s current resident hawk must be near. Every time we see the hawk I’m reminded of Bruce Wilshire, and the words I read in his book and the phrases he used to use in class come back to me. Tonight I read some passages where he talks of fugues appropriately (recursively? fractally?). This wildness is necessary to live. No soul without body.
