Opened the box today and was expecting to count eggs but found wee ones instead! They must have hatched a couple days ago. However, I couldn’t find any adult bluebirds in the area. How long will the mother stay away from hatchlings? I didn’t think they ever went far.I also haven’t seen a male in the area in a while. I don’t get over there as much as I would like but I am concerned about the situation. The other box on the property has been a HOSP attack death trap. 2 swallows recently and 1 bluebird early in the season were murdered in the same box! I was able to kill a female HOSP but the male is a blood thirsty *******. Maybe I’ll have to set the big trap somewhere hidden up there. I can’t stand around with the bb gun all day. I don’t want to take the box down in fear that the HOSP will go after the bluebird box on the property. Praying it all ends well.
Mom goes far enough away to find food. It’s not unusual for them to not be nearby after the babies hatch. I think your wise in keeping that HOSP nestbox up. You have a Van Ert trap right? Let that HOSP build in that house and then trap!
If you’ve had HOSP attacks, would set up that Van Ert in other box & stick around to see if you can trap HOSP. I’ve heard from people here that fishing line version can work, but the sparrow spooker as we know it has 3 rows of Mylar hanging down to touch top of box on both sides (6 Mylar strips total).
