Hello, I have a Bewick’s wren nesting in a cardboard box on my front porch. My partner and I have done our best not to disturb her. It seems like two of her eggs have hatched, do you know if the last one will? Also, when the babies are grown, what should we do with the next? There are things in the box below it…
Well, there is no way of knowing if that third egg will hatch, but after laying, their eggs should hatch somewhere between 14 to 16 days. So if you know when that third egg was layed, if it hasn't hatched by day 16… It's not going to, most likely.
Once the young have left the nest, they probably will not return, but I would watch it for a week or two before removing the nest, and throwing it out. You just want to make sure and observe, and make sure that the nest is not being used for anything before doing that.
Bewick's wren (Thryomanes bewickii), family Trogolodytidae, order Passeriformes, found in the central and western United States and central Mexico
Time and Place: Within the last 10,000 years, in the Holocene of the Quaternary
Bewick’s Wren is known from the Southwestern corner of North America, with some variation in range based on the season - orange below is during the breeding season, blue during the nonbreeding season, and purple year-round

Physical Description: Bewick’s Wren are small-ish songbirds, reaching only about 12 to 14 centimeters in body length. These birds are brown in color, with long erect tail feathers that are black and white striped. The wings are black and brown striped, with some white bits on certain feathers to give them even more distinctiveness when folded. Their bellies are white, except for their bums, which are light brown. They have brown tops to their heads, with white and black stripes over the eyes. Their beaks are long and narrow, with slightly curved points at the end. They are very round birds, all things considered - and almost always found ready to take off, perching on high alert.

Diet: Bewick’s Wren mainly feeds on invertebrates, especially insects, though also some other arthropods.

Behavior: These wrens will forage on the ground more often than not, using their little needle-like bills to probe into the dirt and under plant material for bugs. They do some migrating back and forth from breeding location to wintering location, but most stay within a local range. These are very vocal birds, with a wide variety of songs consisting of many phrases and repeated notes - though only the males sing, the females only making “plit plit plit” calls for alarm and scolding their babies with a buzzing sound. These birds beginn breeding in Early March, though they do start later in the more southern part of their range, and they tend to mate with more than one mate a season. The nests are made of an open crup of grasses lined with things like snakeskins and placed in nest boxes and crannies. About three to eight eggs are laid at a time, and they are incubated by the female for two weeks before being fed by both parents for another two weeks.

Other: Bewick’s Wren isn’t endangered, and is very common throughout its range; there are a few subspecies that are extinct, but overall the species is doing alright.
