I was excited about watching birds through the clear backed
Nest View Birdhouse I bought earlier this spring (read about it here).
Although I moved it to a bedroom window
and kept the blinds drawn, so as not to frighten the birds,
it sits quiet and empty.
I was disappointed...but all was not lost.
I absentmindedly listened to his instructions on
identifying the nest building habits of Sparrows, Wrens and Bluebirds
and his warning that he sometimes has to clean
House Sparrow nests out of his Bluebird house 3 times a day.
Was I in for a surprise.
We held our breath for the first sign of activity.
Within a week, there was nesting material in the house.
Identifying the nesting style wasn't necessary.
The House Sparrows taking up residence made their presence abundantly clear.
They were all over the house when no one was around,
but once I stepped foot out of the house, they were nowhere to be found.
I couldn't get a clear shot of them through the back door.
So, I one sunny morning I went out to wait.
The first to come out from hiding was Mr. Cardinal,
ready to put on a show.
Soon, friendly Robins joined in.
Seemingly without fear, they hopped ever nearer.
Blue Jay made a brief appearance on high.
It was a cold morning and I underestimated the tenacity of those Sparrows.
I gave up and went in without catching them on the house.
Their tenacity in claiming the birdhouse was unrelenting as well.
I did some research on House Sparrows and learned here that
"House Sparrows are non-native invasive pests, and are not protected by law.
They will attack and kill adult bluebirds (sometimes trapping them in the nest box),
and destroy eggs and young.
House Sparrow nests, eggs, young, and adults may be legally removed or destroyed.
It is better to have no box at all than to allow House Sparrows to reproduce in one."
Clearly, something had to be done.
I learned about mounting fishing line on the house,
which scares House Sparrows, but apparently doesn't bother Bluebirds here.
Our Bluebird house now looks like this.
The House Sparrows are gone...
we're still waiting for Bluebirds.
