Lighting condition was very odd, it was pretty shadowy on top of that sun's light was coming from behind my subject and I was obliged to use internal flash as I couldn't afford external at that time. I had to climb the tree without any preparation. I had to hand hold my d5200 body and sigma 150-500 mm for 1/200 th of a second, not a problem But this thing was doing something like pushups and was expanding its Throat like balloon so I took many shots most of them were blurry.
