Delicious little wild strawberries
grow in a sandy patch of soil in the woods where I walk. The birds usually
snatch them before I get a chance, but this year they are all mine.
Across the lake a friend notes
that the red currents on her bushes have ripened but have yet to attract any
birds.
The woods seem quieter this year. The gulls, whose numbers grow each year,
continue to complain as they circle the lake. But within the trees there is
less flickering of wings and only occasional bird song.
Where are all the birds?
We once were visited by squadrons
of birds, either locals or transients just passing through. Almost daily we
were amused by the antics of the nuthatches as they walked the trunks of trees
upside down. Grosbeaks and finches added colour to our dull days.
There was always noise in the trees
around us. Scolding from the blue jays. The dee, dee, dee calls of the
chickadees. The morning and evening moaning of the doves. And, of course, the
non-stop warbling of the vireo that decided that the best place to sing at dawn
was outside my bedroom window.
We don’t feed the birds like we
used to and perhaps that’s why I don’t see or hear as many. Rampaging bears
smashed most of our birdfeeders a couple of years back and I haven’t got around
to replacing them.
However, there is little doubt
that bird populations everywhere have declined and continue to decline. Birds
are among the most studied critters on earth and any of the many reports about
them do not make for happy reading. Losses over the last 40 years are in the
billions.
Our birds are dying off for many
reasons. Habitat loss is the main one. When we cut down a patch of woods to put
up a shopping mall, we eliminate the homes of thousands of birds. When we slash
and burn tropical forests for plantations we eliminate the habitat of many of
the migratory birds that spend summers with us.
New reports show that the
increasing number of wind turbines are killing hundreds of thousands of birds.
There are many other obstructions, however. Millions of birds in North America
die each year after crashing into communications towers, the plate glass on
high-rise buildings, power lines and guy wires.
Now there are studies claiming
that cats kill billions of birds. The U.S. 2014 State of the Birds report
claims that domestic cats kill 2.4 billion birds every year in the United
States and 196 million in Canada.
Yes, cats do indeed kill birds but
by the billions?
It’s difficult to put much faith
in many of the statistics now tossed around about bird losses. We have to
suspect everything we read because we live in a marketing society drifting into
the Donald Trump School of Communication.
But exact numbers do not really
matter. Throughout the world our birds are disappearing. Martha, the world’s
last known passenger pigeon, died 101 years ago. She was one of 100 species of
birds that have become extinct in the last 400 years.
The watch list of birds nearing
extinction continues to grow. About 1,200 bird species, roughly 12 per cent of
all bird species, are endangered, threatened or vulnerable, says the
environmental group Endangered Species International.
When birds disappear so do other things. Some
birds are important pollinators. Some are seed dispersers important to plant
reproduction. Woodpeckers, for instance, pound at trees and create cavities
that are important to insects and other living things.
When birds disappear so do some flowers and
plants and insects. It’s a chain that
when broken changes our world, sometimes in tiny ways, sometimes in large,
critical ways.
But for all the studies and
reports on what is making the birds disappear, one thing is definite. Almost
everything that is killing the birds is created by human beings.
When we walk into the woods and
notice fewer flickering wings and less birdsong, we have to ask ourselves if
there are ways that we can be living differently.
