If you have facebook, you have probably already read all you care to of my complaining...but too bad it's my blog :)
A couple weeks ago we had a new resident make himself/herself at home in our attic. To Sean's horror it turned out to be family of birds. We have seen 2 for sure and have heard babies. The problem is where they fly in and out of is over nothing but the lovely hard ground 3 stories below so we can't block their hole. We were hopping once they had their babies they'd leave...but what do they do this week...BRING IN MORE "STUFF" for their nest. At least I hope it is their nest and not for company of theirs..ugh!
Here is one of them...doesn't it look sinister...
