As I blog, the 2 baby wrens are considering fledging. The adult female seems to be encouraging them occasionally by coming to the nest box without food. I've also seen her with food on some of these visits making sure, I guess, they are staying fed up. She has been visiting with increasing frequency throughout the morning.
The young fledglings are vocalizing a great deal and coming to the box opening - here's a picure of the larger of the two.
They are about the size of their parents at this point. We assume they are 10 to 12 days old based on assumed hatch date.
I guess this means they'll be out of the box today. Unfortunately, a large storm is forecast for this afternoon and evening. I am worried about them being out and perhaps on the ground during this...then again, perhaps the parents sense this and are hoping to get them tucked securely on a branch against a tree trunk for the evening?
We can only speculate at this point. We'll update you when we have more news.
UPDATE
Wow, that was intense!
In about a 2 hour period, our parent wrens successfully moved their 4 fledglings to an undisclosed safe zone in the holly tree and/or the bush below it.
Yes, 4! Boy did we not think there were that many...there are supposed to be clutches of this size or greater but we just assumed we had 2 until they started lining up to come out of the house.
It seemed perfectly orchestrated by the parents. One at a time, after the mom came to the house, the fledglings made their first flight from the opening of the nest box to the Japanese cherry tree 10 feet away.
Fledgling1 – likely the dude in the photo above – made it into the foliage about 7 feet high. We then lost track of him until we saw him scuttling across the roof of the garage to take off for a short hopper flight smack into the holly tree.
Just then, F2 hurtled out of the nest box and into the cherry tree at about 5 feet height. We lost track of her right away...must of scurried up the branches and headed out.
F3, a little pugnacious guy, arched out of the nest box about 10 minutes later. He didn’t do so good, landing at the base of the designated cherry tree. But within about 2 seconds, he was clambering up the trunk, stopping only to get directions from mom over in the cedar tree. Here’s a couple pictures of the little guy.
After his photo op, F3 jagged over to the cedar tree on a low flight path hitting the wood pile. (The garage where the nest box hangs, the cherry tree, and the cedar tree are at the points of a rough triangle of space, each about 8 to 10 feet from the other; the 20 foot diameter holly tree is on the other side of the garage from where the nest box hangs, furthest from the cherry.) From the wood pile he flew into the bushes below the holly. From there we lost sight of him.
F4, the baby, was left, but not for long. We didn’t see F4 take off, but it must have went well because she was gone in a flash and the parents were shuffling little ones from the cedar into the holly/bush area.
Amazing and very efficient. I couldn’t imagine my mom getting us kittens to get in line and behave so well for much of anything. These wrens have the survival thing down. I am glad we could help by putting a nice home for them away from streets and pretty much away from dogs and other intruders. Fric and Frac can always be a problem, but at this point the fledglings have good flight skills at about 12 feet. In hours they’ll be even better. In a week or two, they’ll be almost as adept as their parents who will continue to defend and feed them through most of this period.
I wish them luck. My female person and I will keep an eye for them and update you if we have news. We’re assuming (based on my person’s experience with wrens) they’ll find a sturdy, safe, crow-free zone to spend the day and feed up as much as possible. After that, their lives will become largely secret in terms of how much we’ll know. I sure hope though, that we see them next year when they’re all grown up.
