If it dosent bother you to have the nest there, I would not worry about them. They can be pretty persistant,you could kock it down a dozen times and if the want to be there, they will.I have them close to my deck and I have three dogs that chase them every time they come out the door, dont care, come back every time.The robins even fallow me when I water so they can get any worms that so happen to surface.So if you dont mind them just let them be they will flush when you go out, and come back when your gone.But if they are making a mess on your deck then I understand you wanting them gone.Just start spraing the hose up there evey day full blast and knock the nest down and maybe they will get the hint.

Kenn and Temple, AWESOME photos! Thanks for sharing. Janie, I read that too (about the male taking out materials to encourage the female to speed up nest building). I'm not so sure that applies to this male and female though :) If you watched the first 4 or 5 days of the videos, Daddy took out more than Mama brought in!!!! And today is Day 14, so if it's supposed to get Mama to make the nest faster, I don't think it worked :) I know I'm over simplifying this...I know that they respond to a complex combination of clues like supply of food, etc. And our weather has been up and down and up and down, too. As far as the female taking out nesting material, with this pair only the male has done it. And in the early days of nest building, I could see that what Daddy was taking out "didn't fit." But also in those early days, he took out as much as she brought in!!! Some days it was hysterical seeing him in the box taking out stuff with her at the hole 'chattering' then her going in with him only to have him slide quickly out with his 'treasure' LOL But yesterday's little piece of ? that he took out...really now! That's a bit obsessive :) I have to watch not to anthropomorphize too much! I'm hoping Mama will start egg laying SOON (as in this week). But I've been fooled by birds before...they don't seem to take MY feelings into their egg laying decisions!! Bluebird blessings, Linda...and may none of us have to deal with HOWRS or HOSP!

just noticed both females in box i really think theres some trainning going on , im watching them with a camera i mounted inside the nestbox...

I don't have a lot of experience with the monofilament line. You should register at bluebird nut cafe and post there as well, it is a little more active than this forum. I visit both sites daily. http://bluebirdnutcafe.yuku.com/forums/63/The-Bluebird-Chatter-Forum-Our-Main-Discussion-Area/The-Bluebird-Chatter-Forum-Our-Main-Discussion-Area
