WBNU is the abbreviation for the white breasted nuthatch, so I assume it'd be BHNU for brown-headed nuthatch. TUTIs are wonderful tenants and parents. Last year I had a pair in a bluebird box where the brood was almost wiped out by HOWR (house wrens). There were 6 eggs and the day before they would have hatched, I found all of the eggs on the ground below the nest box pecked to varying degrees. I put the least damaged egg back in and it hatched. I had a nest box camera and saw that the female nuthatch RARELY left the chick alone and stayed with it every night of its life. I don't know if that's normal or it was this female's reaction to having only one chick. In any case, they are a delight. Hope you have a nest of them someday. Bluebird blessings, Linda...

Last season, these little cuties nested in one of my bb boxes on the opposite side of the yard where the blues nested. The box was partially under a crepe myrtle branch, but they didn't nest this early. When they began building, the entire tree was green and beginning to bloom. Along with the blues, they are checking out the bb box, but the blues chase them off every time. I'm hoping they nest again this year in their former home! You'll enjoy having them. Donna

i was reading this thread with interest. i have a situation where it appears i have 8 bluebirds who have hatched in one nest (thursday may 2, they were born). it may be 9, it's hard to tell. while monitoring the nest in late april i noticed what appeared to be eggs missing from the 3 that had been laid earlier in that week. the reality was that the eggs had been pushed down deeper into the nest and covered with pine straw. the mother kept coming back (may have been another species coming in and covering the egg with straw? i have seen no house sparrows here at all) and eventually she started laying again. turns out, there were 10 eggs total in this nest when she was done! i guess five from the first attempt and 5 after that. bottom line, 8 babies are in there now. i'm putting out meal worms twice a day and making sure there's lots of water nearby in the bird bath, and plenty of shelled sunflower seeds for the parents nearby in that feeder. anyone ever seen or heard of a situation like this?

I guess the story is not over...as I said, little TUTI left at 1:55pm. At about 4:10pm, I heard a rustle in the birdless box (I left the nest there for now). The HOWR FRANTICALLY started to de-construct the nest. Grabbing nest material--fur, straw, grass, leaves--out of the hole! It was in a frenzy!!! It would grab something and almost throw itself at the hole to get the material out! If it went to grab a chunk of fur too big to take out, it pulled and pulled at it till it broke it down to a size that would go out the hole. Fast and furious. I did catch this frenzy on tape so I'll be putting that online in the next few days. I closed off the box for today. I need some rest. I can't imagine how such a little bird can do what I saw it do: peck eggs and throw them out, peck chicks and throw them out, attack almost-fledged chicks, and de-construct a HUGE TUTI nest! Blessings, Linda...
