Second Clutch Complete

Be like the bluebird who never is blue,
For he knows from his upbringing what singing can do
– Cole Porter, Be Like the Bluebird, 1934

bluebird eggsWe took a short trip to Taos this past week.  Left with three eggs in Mama’s second clutch of the year and returned with six perfect little blue eggs in the box.  We’ve had rainy, cool mornings and Mama is in the box incubating as I type.  Typically bluebird eggs hatch in 12-14 days.  I usually just count on 13.  If she laid an egg every day, she would have laid her sixth egg on 16 May, and likely would have begun incubating the following day.  So the eggs should hatch about 01 June.

I’ve often talked about the need and methodologies of deterring marauding House taos pueblo 007Sparrows, but have not discussed wrens.  Wrens can also claim nestboxes and puncture bluebird eggs and remove nesting material.  While HOSP’s are undesirable birds, wrens are not and are protected by federal law.  Still there are things we can do to deter them from building in a bluebird box.

Some tips:  Put nestboxes at least 50 and preferably 200-300 feet away from brushy and wooded areas, especially away from areas wrens have used in the past.  Try a wren guard during egg laying.  Avoid slot boxes and gourds, and don’t crowd multiple boxes close together.

Total chicks fledged from this site is 76.

    Eagerly anticipating their hatching and growth. The eggs are stunning.

    What a beautiful picture those eggs make! Our Western Bb female laid her 3rd egg this morning 🙂 I was lucky enough to witness #s 2 and 3 being laid. I don’t know what the deal is with the mealworms I’m offering. I’ve been hanging the feeder right under their favorite perch for almost 2 weeks, give my version of a bluebird call, and nothing. I’ve seen Mama fly right past it and perch above it, looks down, but doesn’t investigate it at all. I know she can see them moving. There’s a nuthatch in a box in the same area and same thing, no interest whatsoever.

    Pam, don’t understand why your bluebirds don’t take a free meal. I’ve never had one turn them down. Our eggs are hatching early. Two hatched as I type.

      I don’t understand either. Guess I’ll keep trying. Maybe when they have 6 hungry mouths to feed they’ll grab some free meals. Mama laid #6 on Saturday so I’m figuring June 7-8 for hatching. Happy to hear your second brood is entering the world👌
