What do swamp hens eat?

The term "swamp hen" is a bit ambiguous. It could refer to several different bird species, each with its own diet. To give you the most accurate answer, I need to know which specific bird you're asking about.

Here are some examples:

* Common Moorhen: These birds are often called "swamp hens." They are omnivorous and eat a wide variety of things, including:

* Aquatic plants: They graze on water lilies, cattails, reeds, and other aquatic vegetation.

* Insects: They hunt for insects, worms, and crustaceans in the water and mud.

* Seeds: They eat seeds from plants growing near water.

* Small fish: Occasionally, they will eat small fish and tadpoles.

* Purple Gallinule: This is another bird sometimes referred to as a "swamp hen." They also have a varied diet:

* Aquatic plants: Like the common moorhen, they eat a wide variety of aquatic plants.

* Insects: They are excellent insect hunters, catching them on the water's surface and in the mud.

* Small invertebrates: They also eat snails, worms, and other small invertebrates.

* Seeds: They will consume seeds and berries.
