Spring is a frenetic time for birds as it is their breeding season and they are very busy courting, building up their nests and their bodies for the rigor of incubating, and in general preparing for the arrival of the next generation. Last Saturday I took the following shots of a variety of birds carrying out those spring activities.
For several years, I’ve put up birdhouses in the hope of attracting Bluebirds. I must have placed them in the wrong places, because no Bluebird came, and only Chickadees and House Wrens have taken advantage of my birdhouses. Yesterday, I saw an energetic House Wren busy building its nest inside one of the birdhouses.
House Wrens are mostly plain brown, but they sing well and are one of the most common birds in North America and South America.
This spring I put up a bluebird house in our backyard, hoping that Bluebirds would come and set up their nest inside. However, Chickadees took possession of it first, then Sparrows tried to invade. Finally a couple of House Wrens evicted all the other occupants and settled in. They are small birds but very feisty and aggressive.
The House Wren in the above photo was holding a fecal sac that it would take and deposit somewhere away from the nest. It could also take similar looking spider egg sacs to deposit inside the nest. When the spiders hatch, they will help the nest by eating parasites in it.
Unlike other backyard birds, House Wrens eat insects and don’t care for the sunflower seeds in our feeder.
