On June 2, I said there were 5 Eastern Bluebird eggs. The female did not lay any eggs after that, so I’m saying June 3 is the first day of incubation. Based on an average of 12-14 days for egg incubation, that means the eggs should hatch around June 14-16. The parents are reusing the first house they used last year (not the second house where I accidentally killed all the babies http://www.butterfliesandwildlife.com/2012/07/06/update-on-second-bluebird-nest-they-all-died/). The current house is a really good house, and not connected to a wood pole like the one where the accident happened. The only anticipated potential difficulty is the heat. It’s expected to be about 95 degrees for the next week. I did a temperature reading inside the nest while it was 95 degrees out this afternoon, and the inside of the nest was 94.
So overall, we now play a waiting game. I’ll still feed them afternoon mealworms, and they will do whatever they do. Both parents need to be wary of Hawks as the Purple Martins are starting to get a little noisy, and that has already attracted a Red Shouldered Hawk.
Here’s some pictures from the couple today.
