Curly, I, too, had a bird's nest in my Duchesse d'Auerstadt arbor - a cardinal's nest. I spooked her twice. Once trying to tuck in some wayward canes and once trying to get a photo of the babies. Turns out the babies were more mature than I thought. They flew away. Woosh! Scared me good. I was on the phone with my sister at the time, and she was yelling, "Get away, get away, you'll hurt them. They won't be able to get back in the nest." I said, "Sue, they FLEW AWAY. They're fine." Yours is very cute. Just wait till they hatch!

It is the most amazing thing if you get box you can open and see the babies or handle them each day to see the startling amount of growth/changes every single day! Our boxes are right under the power line and the parents will sit on the line and watch us and sometimes chirp, but they are a- ok with their babies being handled as long as you don't let them get chilled and are gentle. I learned the hard way to stop trying to hold them after 12 days when i made one batch fledge early. Kept trying to put them back in, but it was too late and the parents really got mad about that. I don't think we've ever had a nest that went much beyond 16 days though, so it's interesting that they are supposed to stay in 21 days. I don't even open the box after day 12. Yes, predators love blues (any baby bird). When you figure out where you want to put a house, make sure cats, coons or snakes can't get to it. Grease the pole or use a baffle or mount the box in such a way that nothing can get in. BTW, the big boxes sell very reasonably priced cedar blue houses- like $12 last i looked. You may very well get some competition from titmice or chickadees- they all like the same size, so you could get multiples and hang them (titmice are the fiercest mamas- they won't budge and will hunker down and hiss at you!). Blues happily nest close to the others but won't nest close to their own kind. And they love to have a choice of boxes. Some years i've had 3 out of my 4 boxes full. The only ones you may want to evict if the get into the box would be the alien house finches. Knock on wood, i've never had it be a problem, but have head from others that it can be.

What does mama bird think of you hovering over the nest? I'm always interested in bird behavior. Some of them will dive-bomb and get after you while others just watch. When I had a robin's nest in a Hoya, which was under our covered front porch, mama bird would fly to a close spot when we spent time on the porch. If we would sit real still, she would come back and sit on the nest, but we had to be careful not to be noisy or move around a lot. Birds are very interesting creatures! Denise in Omaha

My phoebes had skipped a year of nesting in their usual place (above the porch light fixture near my office door). My mirror set-up had scared them away. I should have realized that birds do not "like" mirrors -- but I didn't think about it at the time. I did see a bird pecking all day at the mirror, looking behind it, then pecking angrily at it when seeing the "intruder" again. That bird came back the next day to peck at the mirror again. I felt sorry for him wasting his time. But, I didn't think about the phoebes reaction being the same. So, they never nested there last year. I removed the mirror, but they still did not return to nest there this spring. Instead, they nested on another side of the house -- under our raised deck (same as last year). But, after the 1st brood was fledged -- THEY MOVED BACK TO THEIR OLD NESTING SPOT! So, the phoebes apparently got fed up with the disturbances created by our toy poodle (who is let out onto our raised deck several times a day.) The poodle would be walking directly over their nest, and possibly pissing over their nest. The nest building started May 25, 2021 and completed on the 30th or 31st. The mother was sitting on the nest on May 31, and there were 2 eggs in the nest. So, the first egg was likely delivered on May 30. By June 3, there were 5 eggs. All the eggs hatched on June 17 -- so, exactly 2 weeks after the last egg was laid. Interesting that all eggs hatched on the same day, even though each egg was laid a day apart. When I peeked, all the shells were gone. So, even tho I didn't see it, I assume that the parents removed all the egg shells. I also see the parents flying away with baby-bird poop. The poop looks like worms, and the parents carry it away from the nest. They either drop it or eat it (it is undigested food). Today is June 23, and the parents are often very busy bringing food. The bay birds are still too small to see without using a mirror over the nest. Here is a link to a very interesting article from 1937, detailing the observations of nesting habits of phoebes as studied over a 3-yr period. A few interesting details: Female does all the nest building. Incubation starts at varying times - sometimes after 3rd egg, sometimes after 4th, sometimes after 5th. The male apparently does none of the incubation. After fledging, the young birds remain close to the nest, getting farther way as the days pass. Both parents still feed the young after they fledge -- feeding them for periods of up to 18 days. Reliance on the parents gradually decreases. The parents may eventually show harsh treatment of the young to get them to go out on their own. Interesting. https://sora.unm.edu/sites/default/files/journals/auk/v059n03/p0410-p0417.pdf
