Finch In The Window

As many of you know, I do a lot of the image processing in our home office. So, I'm sitting at my computer this morning with the windows open so the nice cool spring air can flow in when first I see a male finch sit on my window sill and I think "this is going to be a really great day what a cute little red bird". A little time goes by and then the female finch comes along and I think double wow! A pair of finches. A little more time goes by and they bring back one single twig and leave it in the window. I say oh oh! They then start regularly bringing more twigs. So I think hmmmm... I can't have them building a nest here in this window cause I may want to close it. So the next time the birds leave I close the window and then the momma finch comes back carrying a little twig and is frantically trying to find a way in to "her nest". All I see is this cute little momma finch with a twig in her mouth "hoovering" outside my window, looking me right in the eye, looking lost ! I opened the window again! I think I know what comes next! Tom

PS I just looked up on the internet that finch gestation is 7-11 days. It is about the shortest of any of the birds. hmmmm how long till they can fly?
