When Lynn Goodlad noticed the bird on Tuesday morning she initially thought it was a toy and someone was playing a trick on her.
But when finch-sized bird started moving she quickly realised that she was dealing with something very special.
After failing to find the bird in her guidebooks she went online and posted a photo on the Shetland Birds & Wildlife Facebook page.
Within minutes the phone started ringing and online comments began to flow in. The Rare Bird Alert twitter feed posted a photo to the global twitcher community.
"It just snowballed from there. It has been amazing and a little surreal," Lynn described her morning.
She said a constant flow of people had started arriving near her family's home at Bridge End, in Burra, hoping to get a glimpse of the rare American visitor.
