Hi Corey When in Durban try the Botanical Garden. It is in the city and it is safe to walk around in and you get to see a lot of birds. It opens at seven in the morning. There is a small body of water (the lake) which is sometimes quite rewarding, and several different plant ecosystems. There is also a small outdoor restaurant which opens at nine if you want coffee! I don't know where you will be, but there is an entrance into the garden off John Zikhali Road which links with Cowey Road. There is parking here and a car guard. No entry fee. Here is a list of birds that i saw last time I was there:

if you have to be within the city you could also take a walk along the beachfront early in the morning - say around six. Again, it is a safe environment, well-patrolled, lots of people use it for exercise, but you can see some common seabirds along this route. You can park right there too.
