Song Sparrow






















Forgot to change time on one of the clocks...thought I had an hour and a half for a walk...but really just twenty minutes!....did get a clip of Mallard Pair at the Lilypad Pond....sunny hazy blue and warmwarm....Falls are going strong...at lunch, sat awhile at the Fallen Cedar by Ozone Beach...pics of Song Sparrow and Black Phoebe...light dim, so pics blurry...I'd like to sit at the River for lunch, but tourists keep coming by, last evening and this evening too...diverted both times into the Woods and around to work...Does and Two Fawns were by the Lunch Sit Log this evening...pics....last evening Song Sparrow in same spot, and let loose with one riff...have in mind a post called 'riffs'....

a 'trait' might be what I'm thinking of when I think of 'riff'....
more on this for sometime!!

Link of the Day...this continues yesterday's post....about an island in Lake Michigan that has a unique population of Wolves and Moose....

and here I found the term I searched for in last night's post...
quote
When two interacting species, for example predator and prey, evolve together, they can influence the evolution of the other. This is referred to as coevolution.
