Hi Paul
Big Birding Day is an annual event that takes place across the country, usually in November. It is organised by NatureUganda. You can read more about Big Birding Day here.
It is designed to promote birdwatching and to record the number of bird species. Photography isn’t really one of the Big Birding Day activities (although of course you are welcome to take photos while taking part).
If you love photography, I highly recommend a visit to Sunbird Hill on the edge of Kibale Forest. At the Birders’ Lounge at Sunbird Hill you can watch and photo birds from the comfort of an armchair! Sunbird Hill is 40 acres of forest edge
The area around the Birders’ Lounge has been planted to encourage a wide diversity of birds and butterflies. Chimps, Black and White Colobus Monkeys, Red-tailed Monkeys, Olive Baboons, Uganda Mangabeys and even elephants can be heard (and sometimes seen) here.

Thanks Matata! Webale 🙂

I wish you could celebrate Big Birding Day in Kenya too!
Nature Uganda started as a branch of Nature Kenya (East Africa Wildlife Society). I was in Nairobi recently and attended a Nature Kenya talk all about vultures. These incredible birds are a critical part of the ecosystem and are severely under threat worldwide.
