Wrens are not bothered by passing humans but they can get very bossy if you get too close and many a pet has experienced an angry dive bomb from a wren. While good for the garden they can drive other birds away and can be very territorial and aggressive for their size.
After the eggs hatch, the babies stay in the nest for another 16-17 days until they are ready to try their wings. After these babies have left, the parent wrens may have a second nesting later in the summer as their breeding season runs from March to July. When fall comes these tiny birds will head south to spend the winter.
Every spring I love the songs of birds, the sights of the nesting mommas and, if I'm lucky, the experience of seeing the fledgling baby birds as they leave the nest. Most of the time, they seem to do it when I'm not around; just one day they are gone. It is cheery and it reassures me that the life of the natural species will go on year after year and our world will be blessed by it.
