Some of the world’s most intricate
architecture is not always constructed by
humans. Sometimes the most skilled architectural
wonders are designed by nature. Gretchen Cuda reports on an exhibit that celebrates
birds’ nests:

Judith McMillan didn’t find her inspiration in tree branches. She found it in the
basement of the museum where she works. She was rummaging through drawers
there when she came across a hundred-year-old collection of bird nests.

“This Museum must have 10 cabinets full of bird’s nests.”

She was fascinated and immediately knew she had a new subject for her art.

McMillan is a photographer who has been volunteering at the Cleveland Museum of
Natural history for 20 years. In her latest exhibit, titled “Nesting”, she captures some
of natures most inspiring, and often overlooked architecture – the nests of birds.

“I was looking for nests that were different from each other so that you could see that
these birds were little architects. And there were so many different kinds of materials
used – and then the eggs could be so different. Some with little tiny speckles, some
with different colors some with little calligraphic streaks around them, so it was that
variety that I wanted to capture.”

All the photographs are in black and white – because she really wanted people to
concentrate on the architecture without being seduced by the color. She’s fascinated
by the way different birds chose very specific materials to work with – everything
from marsh reeds, grape vine, or little knotty twigs – like this one.

“This is a vermillion flycatcher – it’s almost like it’s made of pick up sticks in the way
their pushed together.”

And to emphasize the diversity of structures birds can create she shows me an
Orioles nest that’s five inches deep and formerly hung like a basket from a tree.

“I actually had to shine a flashlight down in it when I was taking the photograph in
order to get the eggs to show up.”

Most of the nests and eggs were collected around the turn of the 20th century by
amateur naturalists who never thought twice about disturbing the natural wildlife.

But the practice eventually fell out of fashion as people became more
environmentally conscious and large nest and egg collections were often turned over
to museums – explains Andy Jones the museum’s ornithologist.

“People whose grandfathers were dealing with eggs as a hobby, well their
grandfathers are passing away and so they contact their local university or natural
history museum, and say, ‘hey do you want these?’”

Those specimens were originally collected just because they were pretty. These
days, they’re still beautiful, but they also serve a scientific purpose. Scientists can
look at things such as the thickness of the shells, or the type and number of birds
found in a specific location and tell a lot about the birds. They can see where birds
used to live and how far their territories reached. They can even tell if a bird that’s
extinct now once lived in an area.

Judith McMillan hopes her photographs will not only show how beautiful the birds’
handiwork was, but will also inspire people to do something about saving the birds
that are still here.

“I didn’t understand until I started using a camera myself how you can isolate
something and make people look at it differently–And I hope through my
photographs I’m getting people to take a fresh look at things. It’s hard to have an
appreciation of nature unless you really look at it and start to really care about it.”

Recent surveys have found that many songbirds are disappearing. If people don’t
start caring, those photographs and drawers full of nests might become the only
reminders of many more species that go extinct.

The High Costs of Empty Parking Lots (Part Ii)

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this second report in a two-part series:

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this report:


If you had to pay for a parking space, would you think twice before making a frivolous trip, say, to a convenience store for a candy bar?


City planning researcher Donald Shoup bets you would stay home if you had to pay, or maybe you’d walk instead. That’s a point he makes in his recent book, The High Cost of Free Parking. In it, he tries to show that free parking entices us to waste gas. He says paved lots also compete for better uses of land, like parks or housing. Shoup says the problem’s very real – but to see it, you need to step out of your automobile.


“Any view of suburbia from the air will show you a lot of parking lots and a lot of these parking lots will have empty parking spaces.”


I decided to take a look at what’s Shoup’s talking about in Lincolnwood Illinois, a Chicago suburb. I cheated by skipping the air fare, though. Some new Internet sites can provide satellite photos of your area. I joined two of Lincolnwood’s city planners, Tim Clarke and John Lebeque, in their office to get a birds-eye view of their home turf.


Clarke: “The plus is closer.”


Allee: “Right, and go ahead and see if you can find… There it is. Lincolnwood.”


Clarke: “Wow.”


Lebeque: “Whoa.”


Allee: “So find a retail strip.”


Turns out, Donald Shoup was right. Within a minute, we find a popular grocery store, with a huge parking lot. Tim Clarke recognizes it.


“It’s probably one-third filled. I’m not sure when this aerial was taken. I’ve never seen the parking lot full.”


So why should a busy store’s parking lot be two-thirds empty most of the time? Shoup says it’s the cities’ fault. Cities make the rules. They say how many spaces each new business, house, and apartment building must provide.


By his estimation, city government does a poor job at guessing how much parking we really need. Shoup says governments force businesses to provide enough spaces to meet peak demand, such as the day after Thanksgiving, the busiest shopping day of the year.


“Everyone understands the advice, don’t build your church for Easter Sunday, but we build our parking for the week before Christmas.”


In other words, cities tell stores to build parking for the year’s busiest two weeks, even if most of the spaces are empty the rest of the time. He says, without city pressure, a lot of businesses would create smaller lots or they’d sell off parking space they don’t need.


Tim Clarke, the Lincolnwood planner, says suburbs do err on the side of too much parking, but they’re often planning for future growth. He gives an example of a small Lincolnwood dental practice that had 7 examination rooms, but only used three of them. The dentist wanted to build fewer parking spaces than the village required, because it was small and family-run.


“But one could imagine that that family at some time in life would sell that business and someone would come in and want to use all 6 or 7 examining rooms at one time.”


So city planners have to look at the long term use of a building.


Many of Lincolnwood’s largest retailers actually build more than they need to. Bob Johnson runs a Lowe’s Home Improvement store built in late 2003. He says stores like his don’t gamble with having too few spaces.


“I think customers are going to shop, again, where they feel most comfortable and what’s convenient for them. The key word there being convenience. If they’re inconvenienced, they might drive another couple blocks down the road.”


Shoup says that’s a calculation that businesses have to make. He says market forces can help decide how many spaces should be built, but government should not force retailers to have too many spaces. Nor should it force them to offer only free parking.


In fact, Professor Shoup says cities, especially suburban cities, could use land more efficiently if businesses controlled demand for parking like they control everything else: by setting the right price.


“I’m just saying that cities should not force anyone to provide more parking than drivers are willing to pay for.”


Killing our appetite for cheap, abundant parking could be difficult, but Shoup says pressure’s building for change. He says, as suburbs grow, space gets tight. And that raises prices for all land uses.


“I think most people now are focused on the high cost of housing. I think we’ve got our priorities wrong if housing is expensive and the parking is free.”


In his battle against too much parking, Shoup says the most effective weapon might be a little comparison shopping. Free parking might not seem so cheap once it’s compared to the cost of other needs.
