I best not leave it another 75 years to actually see a Nightingale! I heard it, saw one for the first time ever, recorded the sound and blow me down it came and sat on a branch among the thicket some 15 feet away, and then it shown its rusty red tail before disappearing. It also had a ring on its left leg, see/hear here http://youtu.be/Go1CzJSKnbo
