Yellow-headed blackbirds
live in marshes with an abundance of emergent vegetation.
They are slightly bigger than red-winged blackbirds and
will drive them into the drier areas of the marsh. The
female builds a nest in cattails or sedges a few feet
above the water. To build their nests, yellow-headed
blackbirds use wet grass and sedge leaves, materials that
shrink as they dry and make the nest sturdy and secure.
Four eggs are laid in the nest, and when they hatch, the
males are so protective of the babies that they will fly
at and strike a human intruder. |
