Good Year For Bluebirds

Starting Their Second Brood

I think the Bluebirds are getting more comfortable with our garden now.  They no longer leave us during winter.  We provide roosting boxes, food and water in heated birdbaths when nothing much is around in winter and we help with guarding their nesting box during their breeding season.  Since they have become our resident birds, they have started their nesting early.  Last year they had two broods and this year they have already started a second brood while still feeding their chicks from the first brood.

They started the first brood in April. Once the female lays eggs, we start to monitor the nest box weekly to make sure they are fine.  Four out of five eggs hatched with the 1st brood.

May 7th – not much feathering and eyes still closed
May 14th – They are much bigger and have feathers. This was our last photo because we don’t want them to fledge too early

We stopped checking their nest box when the chicks have full feathers.  If they fledge too early, out of concern for their own safety, they could become other birds food.  So we don’t want to stress them with visits.

The second nest is right by our vegetable garden and the green pole is only a couple of feet from the front of the nest box.  Hopefully there will be another three or more chicks from the second brood.

Eastern Bluebird

The weather is still too cold for spring.  Night time temperature a little bit above the freezing point most nights.  Making matters worse, we had an ice storm four days ago.  The birds, on the other hand, seem to know better since they have started to shed their winter down.  This is the time of year I see a lot of fine feathers blowing in the garden or floating in the birdbaths.    The male American Goldfinches have almost completely turned bright yellow by now, their summer color.

Most of our birds have just started to claim territory and are checking available nest boxes.  Some have already paired up with  mates.  The Eastern Bluebird (Sialia sialis), on the other hand, has already laid eggs.  I thought they had only built their nest since it’s still very cold.  I always monitor our nest boxes in the garden to make sure that there are no House Sparrows (Passer domesticus) nesting there.  Once I saw the female Bluebird leave the nest box, I had to take a peek.

A surprise!

They never left us this past winter anyway.  I think they probably felt comfortable here with food, water and roosting box to take shelter in during winter.  And, plenty of food in spring and summer.

I hope they will have two broods this year since they’ve started the first one early.  There really is no such thing as too many Bluebirds.

Eastern Bluebirds Have Settled

However bad this last winter was, the Eastern Bluebirds (Sialia Sialis) elected not to leave us for warmer digs down south.  Maybe because we provided everything they needed here: food, water and places to roost inside from the cold wind and snow.  This last winter was the first time that they were really present on an almost daily basis.  Once the weather started to get warmer, they started to seriously look for a place to nest.  From an initial flock, there are only four left now.  They have made their territorial claims.  I don’t know whether the pair that is nesting in one of the nest boxes now is the same pair that nested in there last year.  I was unable to find any information on whether they try to nest at the same place every year as the Tree Swallows do.

Last Sunday, Easter Sunday, I spent all day in the garden.  Aside from doing the usual garden chores I also checked on the new residents.  Who’s just come back, who’s nesting where and also monitoring the House Sparrows (Passer domesticus) at the nest boxes.  The American Robin (Turdus migratorius) is still battling his image in the bay window on a daily basis.  A female Northern Cardinal (Cardinalis cardinalis) is building her nest in the front Azalea.  Two pairs of Tree Swallows (Tachycineta bicolor) are taking up residence in two of the nest boxes, one of which is the same as last year.

In the end, to my surprise, I found my favorite Easter eggs.  A pair of Eastern Bluebirds have laid four beautiful blue eggs.  I hope it’s not too cold for them at night (still below 40ºF most night) for them to hatch.  I hope to see them start bringing food in for their young in a little over a week.  And then, start a second brood…

Empty Nests

Time to Clean Up

We’ve been doing pretty well with the birds this year. So far we have hosted a few families – three House Wren, three Tree Swallow, and one Eastern Bluebird.  These are just the ones that used the nest boxes we put up in the garden.  The first Wren family has already fledged.  There were five chicks, but only four of them made it.  The second and third are still feeding their chicks, three in each nest.  Chicks from two Tree Swallow families had fledged few of weeks ago, four in the front yard and three in the back yard.  The chicks from the back yard were the ones who conducted their flight training over the garden.  The third Swallow family’s chicks, three of them, just hatched recently, although I think it’s a little late for the swallow.  I hope the chicks will be strong enough to migrate south in late summer.

A family of Eastern Bluebirds had settled in the old Swallow house after they were chased from their original choice by a House Sparrow.  They successfully raised three chicks.  They might start a second brood since we still hear the male calling from high up in a tree.  It would be really great if they do.  They are incredibly beautiful birds to watch.

But now it’s time to clean up.  I waited until the chicks were no longer coming back to roost in the nest boxes before I removed them for cleaning.  It dawned on me when I opened nest boxes, one after another, that this is probably how the phrase “Empty Nest” came to be; when the kids are grown up and have left to live their lives.  It was a sad moment but satisfying at the same time.  I’ll put the clean nest boxes back up after they have dried so the birds that want to start a second brood will have a chance to do so.

I’ve been keeping track of who nests where, so it’s a good thing to recognize the nest construction technique of each bird.  I am always fascinated by the Tree Swallow’s nest.  They line their nest with feathers, mostly white ones on top of a woven grass platform.  The images below are a little bit yucky since a few chicks were in there previously.  I think they are pretty interesting though, to see how different birds build their nests.
