Sorry but I can't comment on the squirrels. I used to think they were cute until I had a large vegetable garden in Austin. Where I live now they're still pesky little rodents digging up my perennial beds and container plants and throwing acorns at my head.
Yesterday shortly before dark I was playing with my cellphone trying to take some Winter Interest pictures. That's when I remembered that part of the camera shake was made worse by a slight breeze just as I was hitting 'shoot'. Dang it. And double dang it because I planned to spend time today practicing but wouldn't you just know that it's been raining all day.
Last night I did compare a number of pics on my phone with those that had been uploaded to my computer. Big difference! Bye bye blur except for the occasional shake.
