While the male House Wren is singing his heart out each morning (see my last blog post), the female is doing some serious business now. The males actually start to build the nest, way before a female even makes a commitment, but it is a loose collection of grass and twigs and they usually build more than one. The females choose and finish the nest to their like before they lay the eggs. Our wren in the front yard is obviously giving it the last touch and making it soft and comfortable.
