Round 2 begins …

IMG_2132 ldJust twelve days after our first 2017 brood fledged,  Mama III began building her second nest.  Usually our bluebirds attempt three broods.  Rarely four.  Weather-wise, the first brood is the easiest and the second not bad.  Once we are into the dog days of summer, heat is a killer of eggs and babies.

After the first brood fledged, I threw out the nest and washed the box with a garden hose.  As the sun moves toward the Summer Equinox, the box would soon be in full sun in the afternoon so I moved it to the south and closer to the Live Oak that provides shade.  It’s now right off our patio, but the bluebirds don’t mind.  They recognize the ‘worm guy’ and welcome my presence, Daddy III usually wing waves and chatters to me, then flies to the feeder.  It’s obvious what he is saying.

I have my box mounted so that it is easily moved.  Electrical conduit comes in 10-feet thunderbird 017sections at the big box stores.  Cut a piece in half and you can make two mounts.  Buy some conduit hangers and attach them to the back of the box with the box mounted as high as possible on the conduit.  While at the box store go over to the section where they have cut re-bar and select a size that fits snugly, but not tight inside the 3/4 inch conduit.  Drive it into the ground and place the conduit with the nestbox attached over the rebar.  I’ve actually moved the box with eggs inside by just sliding it off and careful not to jostle the eggs.

It usually takes a female bluebird about a week to construct a nest and in warm weather, they begin laying immediately.  The males play no part in the nest building.

The first brood has not followed Daddy to the yard yet, but I suspect they will soon.  Stay tuned for Round 2.

First brood fledges …

Because the bluebird is beautiful and readily accepts the help of humans, and, because people love to nurture beautiful animals, especially those that are endearing, a strong natural bond is forged between man and the bluebird at the nest box. In many cases, that relationship not only lasts a lifetime but also grows into a greater awareness of the plight of all wild animals and the plant kingdom on which all animals depend.
– Gary Springer, NABS Director, 2005

I  mentioned the babies have been peering out of the box lately.  This is a sign they are about to fledge.  Normally they fledge in the morning, but last night I heard a bluebird calling loudly.  Went to the kitchen door and one of the babies was perched off the patio in a Japanese maple.  I saw one other on the ground under a Chaste tree.  I had no way of knowing how many were still in the box.  I could see a head bob up now and then, but no clue of how many were left inside.

I  invited a photography buddy to come over early this morning in hopes to get some fledging shots.  Turned out that only one chick was left in the box.  It took him an hour to get the nerve to jump.  He got his feet up on the edge of the hole several times, but would chicken out and jump back inside.  This went on for quite some time when a colorful male goldfinch landed nearby.  Both cameras were clicking away when I heard the bluebirds fussing and the chick was in the air.

As usual, the parents have them down on the creek in some 80-foot pecan trees.  I bluebirds 008suspect in a week or so when the chicks can fly better, they will visit the back yard.  It’s always gratifying to fledge a brood.  I worry about their survival, but I’ve done my part as a bluebird host and it’s now up to the adults’ good parenting and just plain ole luck.  Most species have adapted a reproductive process that assures their persistence.  Those species that produce many young tend to have high mortality rates in their offspring.  Within a month, these chicks will be pretty much self-sufficient although they will follow Daddy around for some time learning survival skills and the best places to bug.

First eggs hatch

As long as there are bluebirds, there will be miracles and a way to find happiness.
– Shirl Brunnel, I Hear Bluebirds, 1984

bluebird babies 052 copyI calculated Mama’s first of season eggs would hatch on 09 April, but a couple of little chicks couldn’t wait to get out.  Mama has been spending a lot of time in the box incubating.  I went out on the patio yesterday afternoon and saw her come in with a bug so tiny I could hardly see it and enter the box.  This could only mean one thing.  I opened the box and two wobbly little heads popped up with mouths wide open.

We are headed to Fayetville to visit with grandson Greyson this morning and on to Branson for a few days, so won’t be around much for a week.  The bluebirds don’t need my help until then anyway.  They instinctively match the size of bugs they catch to the size of the chicks.  They are too little right now for me to supplement live mealworms.  I’m sure the parents will miss their mealworm breakfasts, though.  The other morning I was standing in the kitchen with a cup of coffee peering out the door that is covered with plantation shutters.   Daddy III, who has only been with us since last July, saw me and flew under the covered patio, hovering and chortling in front of me.  He now speaks and wing-waves to me when he is perched in the back yard.  Bluebirds are just such sociable birds!  We have a number of birds around the house, but none show any signs of a relationship other than the bluebirds.

Our backyard bluebird babies typically fledge in 17-18 days.  That would mean thisbluebirds 024 brood will exit into the world on or about 25 April.  They will signal their intentions with a lot of peering out of the box, gradually getting bolder.  It’s going to get crowded in the box with six young ones.  Looking forward to our trip, but also getting back to enjoy and protect the bluebirds.  May the bluebird of happiness visit your house!

It’s gonna be a big family …

A man who never sees a bluebird only half lives.   – Lewis Gannett

bluebirds 008 copy.jpgMama III has been a busy little bluebird.  She has increased her first clutch of the year to six little blue eggs.  That is a big bluebird family.  I have a neighbor who has seven in his box.  Likely his birds are offspring from here.  Mama began incubation on 27 March, so if we use 13 days of incubation, the hatch should be around 09 April.  Looking forward to the big day!

A brood this large will challenge the parents to provide enough food, ferry away fecal sacs and bluebirds 024protect the nest.  I’ll provide live mealworms so the parents won’t have to work so hard and don’t have to be away from the nest for long periods.  I’ve raised mealworms before and may again, at least until the summer gets hot and we migrate to Colorado.  The North American Bluebird Society has an excellent fact sheet that provides a lot of info on mealworms. North American Bluebird Society.  A good source to order mealworms in bulk is Rainbow Mealworms.

I’ll order some mealworms today so we will have a good supply on hand when the babies hatch.  I’ll get a few extra for my neighbor Ken.  When the babies first hatch, they can’t eat the mealworms yet, but the parents can.  I always see the adult birds bringing lots of small spiders to the newly hatched bluebirds.

Total chicks fledged from this site is 70.

Five little blue eggs …

bluebirds 012 copyOn a cold, windy, rainy Spring morning Mama laid her fifth little blue egg.  She is not incubating yet, so maybe she is not finished with this clutch.  I’ve only had six eggs once before.  Five babies fill the box to capacity as they grow and are a chore for the adults to rear, although food is not a problem as I supplement live mealworms for the chicks.  I suspect tomorrow morning will tell the tale.  Most likely Mama will begin incubation.   Then we just sit and wait for them to hatch.

Daddy III will most likely bring her some bugs while she is in the box  on eggs.  This is the first brood he has sired here, so he is a new father.  He does have some experience feeding and caring for babies after he became a surrogate daddy after Daddy II’s death last July.  Watched him take a few sunflower seeds from the tray feeder this morning, something the bluebirds seldom do.

A little Eastern Bluebird (Sialia sialis)  taxonomic history:   Sialia is the Latinized, neuter plural version of the Greek word sialis, a noun meaning a “kind of bird.” The Eastern Bluebird was the first bluebird classified by Carolus Linnaeus (1707-1778), so he gave it the species name sialis. He placed it in the genus Motocilia, which is now reserved for the wagtails. In 1827, William Swainson decided that the bluebirds needed a genus of their own within the thrush family (Turdidae). He selected the generic name Sialia which he simply adapted from the species name sialis that Linnaeus had used. Therefore, the scientific name for the Eastern Bluebird is Sialia sialis (pronounced see-ahl’-ee-ah see’-ahliss). The Western Bluebird and Mountain Bluebird, the two other species within the genus, were named Sialia mexicana and Sialia currucoides (coo-roo-coydees) respectively.

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.

Spring on the reddirt hill

IMG_4346 ldThe astronomical calendar of  heavenly bodies shows the Spring Equinox will occur on March 20 at 5:29 a.m. CDT.  Most people consider this the beginning  of Spring.  The politicians have us moving our clocks forward tonight and some regard that as the first day of Spring.  But, on the reddirt hill we know Spring is here when Mama Bluebird brings her first mouthful of grass to the nestbox.  That happened this morning.  The season of renewal has officially begun.

Last year Mama began her first nest of the season on March 2.  She normally starts nesting on a bright sunshine-filled day, but today is gray and dreary.  For some reason the alarm on the biological clock in her little body rang this morning.

It will take about a week for her to build a cup-shaped nest and line it with fine grass.  After that it won’t be long until the first little blue egg will appear. Another week will go by before her clutch of eggs is laid. Then incubation will begin.

Recall that Daddy III has not been with us too long and this may be the first brood he yardbirds 001has sired.  Last July with three chicks in the box, Daddy II was killed by a roadrunner.  Within days this male was following Mama and jumped right into the role of providing bugs for the babies and ferrying away fecal sacs. Photo is a recent one of Daddy III, he’s prime right now and so is Mama.  A season of raising babies takes a visible toll on the bluebirds, especially the females.  By August, Mama will be worn and thin.  Ready for some time off.  The last brood of three from 2016 followed the parents around most of the winter, but I haven’t seen them lately.  Daddy wouldn’t allow the males around now that breeding season is here.  Male bluebirds are territorial and generally speaking won’t allow another nest within about 100 yards of theirs.

The 2017 breeding season has begun, so we will be making regular entries into our diary.  Note that you can subscribe to be notified of new entries.
