Still Waiting

I haven't posted in a while because there have been no changes to the nest and I have been busy with workshops for school. I do check in on momma bird every morning and evening. She is staying on the nest a LOT more this time around. The last time around I could go out there most evenings and she would not be on the nest so I could take a peek at it. I am wondering if it has to do with the extreme heat that we are having. Maybe she is having to protect the eggs from it? I have started to go out there several times just to check the nest but she is always inside so I don't want to disturb her. I did get a picture of the eggs the other day but nothing had changed. We are on Day 9 from when I discovered the first 3 eggs. According to what I have read she may have waited until the 4th egg was laid to start incubating. So that may put us at Day 7 or 8 for Incubation time. Incubation typically lasts 12-14 days. So we are getting close to hatch day! I am hoping by the end of the week I will be posting with pics of the new babies. I am so excited.
