You will hear the males singing all day long during this time which is for attracting a mate and also for guarding their nest. They are very vocal during their breeding season which is from March to July. House Wrens are those cute little brown birds that you see hopping around your shrubs or garden. A House Wren can live up to nine years in the wild.Raccoons, cats, oppossom, rats, and snakes will eat their eggs and their young chicks. Hawks and owls are predators of the House Wren adult.They will invade other nests such as chickadees and sparrows piercing their eggs or dragging their young out of the nest if they are within or near their breeding area. While House Wrens are tiny and cute little birds, they are far from being nice when it comes to other bird nests.They feed mainly on insects such as beetles, caterpillars, flies, grasshoppers, moths, crickets, and also eats spiders.The young leave the nest about twelve to eighteen days after they hatch.Incubation takes twelve to fifteen days and during this time the female will leave the nest from time to time to feed.This is to help control mites that may take over the nesting area. House Wrens are known to also add spider egg sacs to their nesting materials.The nest is made up of sticks, grass, plant materials, weeds, and feathers.The nesting site is usually found lower to the ground.The female will lay an egg a day until she lays up to six or seven eggs.The only time that I spot them in a tree is when I hear them singing and I follow the sound. When I spot them they are usually hopping around among my garden or low near bushes.
Then come about October it will migrate to the southern most states and into Mexico. They like open meadows, gardens, hedges, orchards, open forests, groves, woods, parks, you name it. House Wrens are one of the most common backyard birds that breed throughout most of Canada and down to South America and the West Indies. Then she chooses the best one for laying her eggs which can be up to 7. The interesting thing is that the male will set up a number of nesting locations in any of these things so that when he mates with a female he can take her to each one of these dummy nests.
You see they adapt very well to being around humans. In fact this wren will use planters, boxes, flower pots, wreaths, drain pipes, and even your store bought decorative birdhouse that you have placed somewhere on your patio for their nest. House Wren nesting habits starts with sticks placed by the male in a couple of nesting cavities which can be in anything from a nest box to an old boot for this bird. I can tell because I have two nesting boxes in my yard that have sticks sticking out of the holes. You see male House Wrens generally only sing during breeding season and since it is July they are probably working on their second brood by now (they breed from March to July). This is not a complaint mind you but an observation as I always enjoy hearing this bird sing.
It is loud enough that I can hear it through my closed windows with the air conditioning running too. From sun up to sun down I can hear this little, plain brown wren (4.3 to 5 inches) calling repeatedly. Probably one of the most vocal birds this time of year is the House Wren.
