I have one house that's being used this year. Same one as last year. The new houses I built and hung last fall have no residents. I've read they are territorial and will reuse the same nesting box for several years. I was hoping to have a few pairs, but I'll take the one. I tried to get photos inside the house yesterday, but mama bird wasn't too eager to let that happen. And I didn't want to scare her away. I've been seeing other broken eggs laying around the yard. They're tiny and white. I'm thinking the squirrels are the cause.

OMG, Evelyn! If you knew how many baby mockingbirds I hand fed while working at Audubon, you'd die! People would bring in baby birds all day long, and you couldn't convince them to leave them alone, so my job was to take care of them and get them prepared to be released back into the wild later on. One of the reasons we do not encourage people "rescuing" the baby birds is that there comes a time when the bird has imprinted so strongly on the parent bird, it will not take food from a person. You can cram it down their throats, but it will just sit in the crop area and not be digested. So removing them from the parent's care is often a death sentence. Now if a whole nest comes down (like during a storm) sometimes there is no recourse but to rescue them and try to feed them. And I know techniques have improved GREATLY from the days I was involved in bird rescue. So the odds might be better now. But lordy, lordy...I must have handraised at least 200 baby mockingbirds in a couple years time. Not to mention jays, grackles, thrashers, titmice, and maybe 1,000 mourning doves! (My least favorite baby birds of all time.) Anyway, your picture is a trip down memory lane for sure. Saintp, the length of time it takes an egg to hatch varies from species to species, but usually it is not very long. A week or ten days, often. I'll see if I can find out about bluejays. I don't remember. Maybe I never even knew. But the info is probably out there somewhere. Will get back to you later. Marcia

Sounds like you really have some challenges. You have my sympathies! A tiny poked hole is more likely a house wren's thin sharp beak, sometimes taking them some distance away, or simply tossing them out. The house sparrow will toss the eggs out, but their finch-like beak would not as likely make a tiny poke hole. And the HOSP is more likely to stick around, harass, or even take over the cavity. "Do BB's destroy their own eggs" ... No "the nest possibly could have been flooded?" ... are there leaks that could be fixed? "Are the HOSP really sneaky" ... yes, but HOWR are sneakier ... "and resistant to the Sparrow Spooker?" ... yes, and house wrens will not be deterred by a sparrow spooker. House Wrens are even sneakier, faster and silent, leaving no evidence behind, only destroying eggs or young. You might hear them singing, but might never, ever see them! There are some links to sound files of house wren song and chatter on Bet's web pages, so you can learn to hear the unwelcome sounds of house wrens. Visit Bet's web page for more info. And by the way, the Carolina Wren is a very different bird, welcome almost anywhere; not a threat to other birds. BlueBars Here is a link that might be useful: http://www.sialis.org/index.html

The story doesn't end there, I'm afraid. As I said, I plugged the hole in the nest box where the TUTIs nested. While I was distracted with them, a pair of bluebirds who have been hanging around here started a nest in my second video box which is in my back yard. I hadn't been paying enough attention because I had intended to put that one out of commission also. By the time I turned my attention to that box, the nest was almost done. Mama has been working on the nest and at the same time working with Daddy to feed the 3 (maybe 4) fledglings from their first brood which grew up somewhere else (I'd seen the parents come to my feeder and carry mealies off beyond my yard a few houses/never did find where the nest was; I'm guessing they got evicted by our little brown bird 'friend'). So for the last few days I have been so happy to see the whole family in my backyard, all 5 or 6 of them. They go back and forth from the mealie feeder to the top of the nest box which is not far away. Anyway, I WILL be monitoring the box as carefully as I can. My husband rigged up a cord that goes from the nest box to inside my kitchen. If I see a HOWR on the box or in the box, I pull on the cord and can shake the nestbox! Hope I never have to use it. The box is also easier to get to than the one in the front (no steps, yeah!). I have evidence that having the whole BB family around will offer them a lot of protection. As I watched (and recorded), a HOWR went into the nest box & started to pick at the nesting material with the intention, I'm sure, of throwing it out the hole. However, 'The Family' showed up and blocked the HOWR IN the box. I swear that HOWR must sit somewhere and watch the BBs cause it had the guts to go into the nest while Mama is actively in and out of the nestbox while working on the nest. Actually prior to getting trapped in the box that time, the HOWR had gone into the box & started picking at the pine needles but I chased it out quickly. So if you go to my dropshots page (guest password birdbrain), there's a new video 'HOWR gets trapped in box by bluebirds'. If you listen carefully to the video, you can hear the bluebirds 'chatting' while the HOWR quivers at the bottom of the nest. Not sure what the quivering is all about but I know that some animals (like cats, for instance) 'quiver' in anticipation of pouncing/striking. You can see that it tries to get out the hole twice to no avail (it seems to 'throw' itself at the hole). I was afraid that one of the parents was going to go into the box and get hurt. Yes, maybe there would have been a battle and the bluebirds MIGHT have won but I didn't want to take the chance so I opened the back door (this was before I had my 'shaker cord'). My two male dogs got out in front of me and not only chased away the bluebirds but also the wren. Amazing video, though! The nest is done now and when the first egg is laid, up goes the wren guard, and I go into active monitoring. Blessings, Lina...
