Open Bill Stork (Juvenile)

For winter visitors i went at Tena wetland in the morning of 25th November 2017 and find nothing new ducks so thought to walk surrounding of lake before i return home at 10.30am as it became bright sunny day.after walking of 100+mtr ,i saw a Juvenile of Open Bill Stork.very carefully approached towards it and i reached 20mtr away from it even though this juvenile ignored me.then i sit there and took good shot.i was waiting for some moments like stretching of mouth/wings and sudden started itching..boom clicked but missed whole frame as i forgot to reduce the zoom.
