I saw 3 raptors circling the reserve and identified them as white-bellied sea eagle.
On my way back from route 3 to route 1, I noticed a dollarbird on a branch. I decided to approach it cautiously and luckily, I was able to get a decent shot of this bird.
Here are some of the other birds, I was able to photograph.
Brown throated sunbird (female)
Scaley breasted munia
White breasted waterhen
