Glad you were able to see & get the picture. This is one I see maybe up to 15 times or less each year. I get the Song Sparrow daily.
Depending on where you have your feeder set up if it's able to be set up close to a sliding glass door that has a light switch for you to turn on at night for it if you get a stronger light bulb and then leave the light on at nights for the flying squirrel to get comfortable with then you might not have to use the flash on the camera if you sit outdoors and are in a good position. The flying squirrels are also known to be quite friendly so if you are outdoors often and let it get comfortable with you then you might not have a problem getting better photos.
What do you notice with the camera that's making a difference for you to get better shots than with your last one?
The 2nd & last ones are really beautiful!
Glad to read your are safe James. I have other friends down in Tennessee so I've been praying for them.
