A Recap’ of The Breeding Season

Eastern Bluebird

One of my fellow bloggers asked me recently how the Bluebirds fared this season.  A light bulb went on in my head how about a recap’ of this past breeding season?  The Eastern Bluebirds (Sialia sialis) have done quite well.  To our surprise, they have raised three broods this season however the broods may not be of the same pair.  I know one pair has raised two broods since their chicks were allowed to hangout by their new nest box when they started the second brood.  But the third which nested in the front yard nest box later in the season didn’t have any chicks around.

Below is my progressive observations of the second brood.

June 6th – Three eggs
June 17th – Five eggs
June 25th – All hatched
June 29 – Most of the chicks developed hard feathers. It was the last observation. We don’t want the parents and the chicks to get too anxious and try to fledge too early.
One cloudy day, the chicks were flying around, observing their parents and learning how to get food from the feeders.

In the years past, we have only observed Bluebirds raising one or two broods at the most.  Then to our surprise & excitement, we discovered a third brood in the front yard.  I have seen the Bluebirds on this nest box a few times but have also seen House sparrows (Passer domesticus) on it too.  The vicious House sparrows zoom into their nests, peck & break their eggs & will not let them have any peace.  However when we tried to trim the hedge by the nest box, the Bluebirds wouldn’t leave the area so we checked the box.  Bravo! What a pleasant surprise and hedge trimming was immediately suspended.

July 28 –  Four beautiful blue eggs. We promptly closed the box and leave the area.
August 6 – Three chicks
August 11 – All hatched
August 15 – Last observation

I don’t know how many of the chicks from these three broods have survived to adulthood.  What I do know is that we hear more of their calling in the air, around the yard, than years ago.  They  come to the feeders and baths year ’round.   They also look for places to roost in our garden in winter.

Three of them at their favorite feeder a week ago.
Looking for a place to roost

We have not yet had a heavy snow.  We will see more of them once the ground is covered with snow and the lake is frozen over.  I think they decided to stick around in winter because we have food, heated bath and warm places to stay.  We pretty much rolled the red carpet out for our avian friends.  The only exception is House Sparrows….for this bunch, it’s war.

    1. I think they were imported from Europe many years ago, now they have become pests. I love birds but the last straw with the House Sparrows was when I found they destroyed a Bluebird nest and shattered their eggs. This year they killed one of the Tree swallow babies. They are aggressive and mean. Not just territorial, but destroying indigenous birds every chance they get.
