Though we tend to think of hummingbirds as cute, dainty little things, in reality they make bold and fierce competitors.
They don't let their guard down for a moment while defending their territories from other hummingbirds. They must also watch out for other animals that might prey on them, such as American kestrels in North America or tarantulas in South America. Praying mantises are also known to capture and kill hummingbirds.
