All solutions to HOSP control have drawbacks, but not controlling them at all has the greatest drawback. – Cherie Layton, The Bluebird Nut, 2006
The bluebirds have returned after being gone for about six weeks. Last week Mama began a nest and again we made a trip to Texas. When we returned the nest was complete and had three little blue eggs inside. She hasn’t laid another in the past couple of days, but she doesn’t seem to be incubating either.
Female birds seem to have an innate thermometer that tells them when they need to sit on eggs and when they don’t. It’s hot, mid-nineties, so the eggs won’t need much warmth from Mama. I had move the box back out on the hill after the bluebirds left so it would be more visible. I’ve moved it with the eggs inside so that it is now shaded in the afternoon. Heat can kill eggs and chicks.
It’s good to have the bluebirds back in the box and yard. Yesterday they flew in followed by the four juveniles they hatched earlier this year. Good to know that all have survived. The Sparrow Spooker is in place and I’m not seeing any HOSP’s in the yard. I’m a little concerned that Mama is not incubating, but maybe she is not through laying. We’ll see.
