White-rumped Shama

i was at Vansda National Park with family n cousins on 17th May'15.its around 8am n searching birds at little lake but didn't find so we had think to move at different place in my car.one of my cousin was driving and i was sitting at back seat,within 3-4min of driving a bird was crossed our car and i asked to stop car. my camera was on tripod and in hurry free my camera but during these procedure the camera setting was changed n i didn't noticed.when i took 1st shot the flash was shoot n m surprised that why this happened.camera was set on night mode,even vibration control was off. that bird fly away.
i was so disappointed when i see the picture in cam's display coz it was White-rumped Shama n we were just 10-15 ft away, i missed the crisp shot.
