First little blue egg …

bluebird egg 001 copyYesterday we celebrated our first little blue egg of the season!  It’s cool this morning, so possibility Mama III might not lay another today.  Bluebirds can lay an egg per day, but it’s not unusual for them to skip a day, especially in poor weather.  I moved the box so that it is now in afternoon shade and will put the Sparrow Spooker on today.  It’s a device that attaches over the box with waving mylar strips that keeps sparrows away.  Once the bluebirds have an egg in the box, Mama’s maternal instincts will be stronger than her fear of the spooker.  House sparrows will destroy bluebird eggs or kill babies to nest in the box.  It’s incumbent on bluebird hosts that lure birds near their homes to protect them from marauding HOSP’s.

It will take Mama 5-7 days to lay her complete clutch of eggs and incubation will take 12-thunderbird 00614 days.  She won’t start (Photo is Daddy staking a claim on the back yard) incubation until all the eggs are laid.  The first brood of the year is generally the easiest.  The parents are rested and have strong instincts to fledge babies.  As the summer temperature rises, heat can addle the eggs or kill chicks.  That is why I have my box rigged up so that it is easy to move (even with eggs or chicks inside) to keep it in the afternoon shade as the sun marches north to the Summer Equinox and back south again. We are looking forward to another productive season for the bluebirds on the reddirt hill.

Total chicks fledged from this site is 70.

    I’m really looking forward to a season without dramas (fingers crossed). I enjoy the way you balance science with the passion you have for these gorgeous birds.

    Hello, I enjoy reading your posts as I am a bluebird fan as well. We have had bluebirds for many years, feed them mealie worms, and use a Gilbertson box. Last year was the first year that we lost our eggs to a house wren that came. He is back and I worry that he’ll again poke holes in the eggs. I’ve read extensively about how to prevent a house wren from destroying the nest or eggs and will make a wren guard after the bluebirds lay their first egg. We don’t seem to have any trouble with sparrows, just this house wren now. Do you have any suggestions? It was so sad last year to have lost two broods. Thank you.

      You might put up another box nearby and maybe the wren will select it. They like their boxes in brushy areas rather than open like bluebirds prefer. Good luck!
