Life and Death in the Backyard

Perhaps my greatest pleasure living in southern Delaware is my back yard.

I live in a development of three quarter acre lots.  I chose my corner lot because it is almost an acre and backs up to a farmer's field.  Beyond the field is Route 1.  I am far enough away from Route 1 that the constant traffic doesn't bother me but is rather like a living panorama.

The real panorama is what goes on in my backyard during the spring and summer months.  I love grow flowers and herbs.  I also love to provide a natural habitat for several native bird species.

I have my back yard lined with three blue bird (or swallow) boxes and one purple martin house.

The past two years I have had bluebirds take up residence in one of the bluebird houses and raise two batches of four baby bluebirds each season.

Each year I have had to fight the common house sparrow who are a non-native bird species.  The sparrows come in early and take over the bird boxes, fighting off and killing the native species of birds that I am trying provide a home for.

This year the sparrows have been particularly aggressive.  So aggressive that the bluebirds have given up even building a nest in the same box that they built in the past two years.

A pair of swallows is attempting to build a nest in that blue bird box. So far the sparrows have killed one of the swallows.  I came back from an errand one day and checked the box only to have a sparrow fly out of the box, leaving a dead swallow in the box.  That was two weeks ago.

Since then Bill has built a contraption to trap the sparrow in the box.  After I returned from my visit in Pennsylvania he showed me the male sparrow that he caught with a bottle that he put to the door of the bluebird house that he had trapped.  He intended to keep the sparrow for me but the sparrow died in the bottle.  He didn't know why it died because he left the lid ajar for air.  Maybe the bird died from shock that he was caught.  Good.  I was going to twist its neck anyway.

Since then another pair of swallows has been attempting to build a nest but without success.  Last Saturday I was checking one of the other bluebird boxes and I was shocked by what I found.  The sparrows had built a nest but to the side was a dead swallow.  As incredible as it seems, the sparrows were going to raise their young with a dead bird in their box!

I took the dead swallow out of the box and tore out the sparrow nesting.  Below is what happens when you let sparrows take over your bird boxes.
This is the dead swallow in the sparrow nesting.

Last year I wrote several blogs about my battles with the sparrows.  I never caught one last year but they never did raise any of their young in my backyard.  I lost count of the nest I tore out.  I threw out a total of 19 if the brown speckled sparrow eggs.  I don't have a problem throwing out the sparrow eggs but I don't think I could destroy young sparrows.  I'm not that ruthless.....yet.  

At the present time there is a sparrow nest in one of the purple martin apartments.  I'll wait until they lay their eggs and then I'll take out their nest, eggs and all.  There is a downside to this.  Last year when I tore out one of the nest the sparrow got into one of the purple martin apartment and killed three baby purple martins.

New Bluebird Nest!

New bluebird nest





















Purple Martin eggs




We have a new bluebird nest! After a delay of about ten days, mama and papa bluebird have built a new, neat nest. The bluebird pair is apparently the same because the Biggest Bluebird I’ve Ever Seen, is again perched atop the bluebird box. Of course there were a few forays into the bluebird box by the errant house sparrow but the Biggest Bluebird I’ve Ever Seen quickly took care of that unwelcomed intruder.

In a day or two I expect to see four small blue bluebird (what other color would they be?) eggs in the new bluebird nest. In about a month the new baby bluebirds will be grown and out exploring their new world just like their sisters and brothers are doing now.

The swallows have built a nest in one of the other bluebird houses. Their pure white eggs are nestled in another neat nest lined with white feathers. It’s interesting that each bird has its own unique nest. The Purple Martins don’t build so much of a nest as they line the bottom of their aluminum compartment with broad pieces of straw. The Purple Martin eggs are also pure white. Only the house sparrow eggs are a tan with brown dots. The house sparrow nests are a mess. Everything and anything is in their nest from trash to straw and plastic.

The Purple Martins quickly claimed the last compartment in their tall six apartment birdhouse when I removed the sparrow nest on Monday. From what I can tell the Purple Martins have already raised one batch of young ones and are now working on the second batch. I think the Purple Martins only raise two batches of young ones before they leave for the season.

This year, for the first time, both of the gourds hanging beneath the Purple Martin house area occupied by swallows. One gourd was occupied by another Taliban sparrow but it only took two cleanings to get that sparrow out of there. I think the house sparrows took up in my neighbor’s birdhouses.

Each evening Bill and I sit out on our deck and watch the Purple Martins sort out their pecking order. We enjoy their graceful swooping of the swallows over our back yard looking for a meal. The bluebirds seem to be more preoccupied with guarding their nest and feeding their young. They make no noise at all whereas the Purple Martins are always squawking about something. We will miss them all when they leave later this summer. Then the quiet in our backyard will be deafening.
