Brianna, I mentioned lenses. What lenses are you planning to use for wildlife? That's an important consideration when you look at camera prices. That's because you need to start with a system. I did start with the Canon 55-250mm lens for wildlife. It was challenging for me, to be able to get close to the wildlife without scaring them off. I actually did pretty well considering the relatively shorter focal length. Then I got the Tamron 150-600mm lens. That made a huge difference for me. It's heavy and bulky but I learned how to handle it (cradle it like a baby).

The advantage of the smaller telephoto lens, was that I could stand still for a very long time near a bird feeder. As long as I was like a statue, some of the birds would come very close. When I got the larger telephoto lens, I had a lot more reach, but I could no longer hold it still for an extended period of time. Some people use relatively expensive tripods that can handle that much weight, but I've chosen to use it all of the time hand-held. So, I had to make adjustments. But the larger Tamron lens is my lens of choice for wildlife.

Here's one of my wood duck photos taken with the Tamron 150-600mm lens. I took that last year on January 1st when we had sun. Where I live in Oregon, sun is not common during the winter months. So, I had to go back many months to find one example for you. Also the wood ducks in our neighborhood, mostly stay here during the rainy months. I rarely see them during the summer, when we have more sun.
