I had an encounter of the Vulnerable bird - Eastern Imperial Eagle in the open scrub jungle of Little Rann of Kutch in late December, 2019. It gave me only 10 seconds to click , after spotting in a camouflage habitat.
But my luck got favour in the Teesta Barrage, Gajoldoba (Feb, 2020) where I spotted it on the river island, waiting for prey (at early morning birding session). I managed to get many clicks from the boat, for 20 minutes.
