Whooping Crane with Sandhill Cranes by Jody Zamirowski |
Birds, like all natural resources, demand conservation
(published 5-19-14)
An extinct bird, the passenger pigeon, is getting lots of attention this year. I’m good with that, and hope you are, too. Every so often we need to pause from the “joy of birding” and think about the serious stuff.
An extinct bird, the passenger pigeon, is getting lots of attention this year. I’m good with that, and hope you are, too. Every so often we need to pause from the “joy of birding” and think about the serious stuff.
Extinction is about as serious as it gets, and 100 years ago
marked the end of the line for “Martha,” the world’s last passenger
pigeon. She died in the Cincinnati Zoo
on September 1, 1914. The story of Martha and her doomed species is well told in
“A Feathered River Across the Sky,” a new book by Joel Greenberg. The author chronicles how the most abundant
bird species in North America dropped from 4 billion birds to none in 50 years.
That seems impossible but it really happened.
Audubon magazine last
year estimated that 1,200 bird species face extinction over the next century,
with many more suffering from severe habitat loss. There are roughly 10,000 species of birds in
the world.
More bad news: The
American Bird Conservancy says fully one-third of species in the United States
continue to decline as their habitats are lost or degraded to the point of
being unproductive.
As we go about our birding lives, playing our listing games
and chasing lifers, these realities hover in the background like a dark
cloud. It’s pretty obvious to avid
birders that certain birds are in short supply around here, such as
black-billed cuckoo, cerulean warbler, golden-winged warbler, grasshopper
sparrow, rusty blackbird and upland sandpiper. Older watchers may recall when
all six were considerably more common. My
last cerulean was in 1998!
Twenty-five bird species are considered endangered in
Illinois, with five more listed as threatened.
Fortunately, a lot of good people care about saving our
birds. Species once on the brink of extinction have been rescued, a list that
includes bald eagle, wood duck, great egret, snowy egret, wild turkey,
Kirtland’s warbler and Eastern bluebird.
The whooping crane population once fell to just 8 birds; now
it’s up to about 500. A captive breeding program saved the California condor
but its future, like the whooper’s, is far from secure.
Success stories can be found locally, too. A really good one surfaced this spring when
the Bird Conservation Network and Audubon Chicago Region released a population
trends study on breeding birds for the period 1999-2012. The report shows that
about half of our locally breeding species have stable or increasing
populations. In fact, birds including Eastern bluebird, orchard oriole, Henslow’s
sparrow, bobolink and dickcissel were found to be bucking a national trend by growing
their numbers here in northeast Illinois. (To see the report, go to
bcnbirds.org.)
The findings are a tribute to the dedicated work of more
than 250 volunteer bird monitors who devoted thousands of hours to collecting
population data based on a standardized protocol known as “point counts.” Data
from DuPage County account for 25-30% of the 14-year database.
“The trends data show the positive impact of active
restoration and management of the native bird species in our natural areas and
wild places,” said Bob Fisher, an avid Downers Grove birder and past president
of Bird Conservation Network.
Importantly, Fisher added, the data indicate where more work
is needed. Certain ground and low-nesting woodland bird species are declining.
Land managers face the challenge of how best to remove non-native understory
vegetation, replace it with natives, and then prevent over-browsing by the region’s
abundant deer population.
Like I said, serious stuff, and the deeper we get into
birding the more we tend to care about bird conservation. It’s a natural progression. If you are looking for ways to help, the BCN
website is a good place to begin. Bird monitors are always needed.
You might also Google “ABC’s Top Ten Tips for Bird-Friendly
Living” for a handy guide or check out “101 Ways to Help Birds” by Laura
Erickson.
There are many organizations worthy of your cash. It’s hard
to choose. But one of the best ways to spend 15 bucks is also one of the
easiest: buy a federal duck stamp the next time you visit the post office. I
love that program and I’m not even a hunter.
Finally, speaking of stamps, I’m fairly giddy about the new
songbird series issued by the USPS. Buy some and use them on your envelopes.
The stamps may not help birds directly but they sure will get noticed, and that
has to be good.
