Squirrel Test Blip

I have a rather good 70-300 zoom lens that I seldom use, so today I dusted it off and tried a few shots.
This is a hand held blip of a squirrel at max 300mm zoom. 
It's much heavier than my standard day-to-day 16-80 zoom (probably the reason for not using it very much).  I must start using it more.
