Flying south for the winter

So it just dawned on me that I have reached and surpassed 42 followers (that's something right?), Oh and that I live where some of the birds fly to in the winter. Iv realized the different perspective on things that my kids will grow up with here. Most of it not bad just so different. I'm not sure why its so hard for me to rearrange some of these things in my head but oddly enough it is. Like the fact that when I see a flock of birds flying on an October evening it doesn't mean they are leaving town but that they are nesting in a tree across the street. I guess this didn't hit me last year because there chosen nesting place wasn't across the street from my only opening window. They are not a bother really just kinda loud in the mornings. They wake up and get to chirping about 7 but by 10am or so they head out. And every evening we can sit on our patio (roof) and watch them fly back to there tree. When I say a flock I mean the sky looks almost black as they fly in, and this takes almost 2 hours. And because there nesting place is so close they look so close that you could touch them. Luckily so far no poopy has fallen on our heads. There are tons of them and only two trees that they all perch on. I wonder to they pick the same branch every night. Because in the evenings they are actually very quiet. The fly in and I suppose go to sleep. The first night we saw them fly through I explained to my daughter that birds need to fly to warmer weather during the winter and that we needed to say good bye to them. Then a couple days later my husband was like, I think they are landing across the street. A week after hearing them every morning I thought, "Aaahaaa, we are the warmer weather. Actually I think this came to me as I was on the web cam with my sister (who is in Missouri) and saw my nieces coming in with coats on and her telling them to get warmed up before there bath. Don't get me wrong its not horribly hot here but its been quite warm this last week or so. It seems to get warmer right before it cools off. But in this area you don't need and AC unit. And for that matter don't really need a heater. We bought space heater units last year but in this new smaller apartment I don't think we will need them. So I'm wondering will we have these new neighbors all winter or when it does get a little colder here will they move even further south.
