I took a closer look at the pictures I am starting to wonder if it is shadow cast. before I took the pic it was going from one branch to another. Strangest thing is it still had the black colouration reason for taking photos.
Sadly I dont tend to get robins around here, the last robin I was was when I lived in New South Wales and it was the Red breasted kind in those pictures. Even the only wrens I tend to see around here are not the beautiful Suberb Wrens but the Red Backed Wren. Still pretty but tend to stay out of town and only seen on the fringes of town or out in the country side.
