the year in birds: 2011

in Me

This tradition is now probably just for me, and my 3 remaining readers!

I took two international trips this year: one to the central highlands of Nicaragua, my second time in this area (you can read about the highlights here and here), and the other a quick trip to Honduras. Also a business trip to California, but no time for birding.

  • New life birds: 25. Most were from the Nicaragua trip. The last one was Chestnut-colored Woodpecker (Celeus castaneus) in Honduras.
  • Total life birds: 1198.
  • Total ABA-area birds: 579. No new species this year.
  • Total state birds: 312 (new this year was Brant).
  • Total birds in my home county: 263 (new: Lapland Longspur, Brant, Rufous Hummingbird, Short-eared Owl). I had 186 species this year.
  • Total city birds: 223 (new species this year: Lapland Longspur, Ross’s Goose, Barred Owl). I saw 160 this year.
  • Total birds at work: 195. Nothing new this year.
  • Yard birds: 136. Nothing new this year.

Happy New Year.

This is Christmas Bird Count (CBC) season, the roughly three-week period at the end of each year where teams of determined folks do single-day bird surveys of established 15-mile diameter circles (history here). Typically, participants are given a photocopy of a road map with the count circle drawn on it with that high-tech instrument, a compass. This can make for some imprecise boundaries, to be sure, and it is important to stay within the count circle in order to improve the scientific validity of potential analyses.

In 2005, I posted a tutorial on how to create a very precise circle in Google Earth that would show the exact circle boundaries and allow you to zoom in, check for promising habitats, save or print the whole circle or just a portion, and all the other cool crap Google Earth lets you do.

Since then, more people have created mash-ups and tools for Google Earth, and I’ve found one that is easier than the method in my previous post. For starters, it’s online and will put your circle on a Google map on the same page where you input your parameters. You can format the boundary line and fill various thicknesses and colors. And you can export your circle into a KLM file that will open in Google Earth, so you can save it, revise it, and enjoy all the Googly-goodness.

  1. Go to the Free Map Tools radius around a point page.
  2. Pick your radius. For a CBC, the radius is 7.5 miles. It will work for any type of circle, of course.
  3. You can zoom in on the map at the top of the page to pick the center of your circle, but for the sake of precision, input the official center by using decimal lat/long. The best way to get this data is to head to the newly revamped National Audubon CBC page, and query the historical results for data on the count circle you are interested in. Use the options to find the count you want — the years you look at really don’t matter. You just want to click on “Make a table” so you can look at the coordinates Audubon has of the count circle center. They’ll be right at the top of the table, in decimal degrees (clickable, actually, to Google Maps, but the map will only show the center point, not the circle itself). These are the coordinates you plug into the Free Map Tools page. If in North America, make sure you include the negative sign in the longitude, or else your circle will end up on the other side of the world. If you only have your center point in degrees-minutes-seconds, you can go to this page and covert it to decimal degrees.
  4. Choose your aesthetically pleasing options.
  5. Click on “Draw radius” next to where you entered your lat/long data.
  6. Presto. Your circle is on the map.
  7. To see your circle in Google Earth, scroll down to the “Google Earth KML Output” section, and click the “Generate KML” button. In the space below, a link will appear to the KML file. Click it.
  8. If you have Google Earth installed on your computer, you can choose to open the file right then and there. Or you can save the file and open it in Google Earth later.

There are other options on the page for viewing, saving, and/or linking to your circle as well. Happy bird counting!

electrifying!

in Flotsam and jetsam

Who knew there is a whole bunch of people on the photo sharing site Flickr that are enthralled with municipal electric delivery systems? Check out the enthusiastic comments on this photo from PowerLine1. Or this guy’s 1700 photos of power lines, arranged into sets by state (although rest assured he takes the proper precautions: “Specific names of transmission lines will not be listed unless it is a line that is being built or is below 345kV. I don’t want information from my hobby to get into the hands to others who would use my power line info/photos in their wrongdoing.”). This DIY’er has photos of his own poles. I had no idea so many people got a charge out of this stuff.

in Urban issues

The Rouge River is an urban river, and its urban character is nowhere better reflected than in its last few miles, after it passes through the campus of the University of Michigan-Dearborn and the Henry Ford Estate. As it approaches Michigan Avenue all sense of riverness ends: this is where the Rouge gets harnessed into its concrete straitjacket, and it remains shackled down to where it empties into the Detroit River.

The channel was built in the mid-1970s by the Army Corps of Engineers for flood control. We’ll leave the pros, cons, and results of that for another discussion. But, among other things, it was a feat of engineering. Consider these photos from 1971 from Wayne State University’s Virtual Motor City project.

That’s the Ford Rouge complex in the background of the photo above. It’s also in the upper right corner of the photo below, from the Corps, just after the channel was completed.

The Rouge is my urban river, concrete channel and all. Technically, you’re not supposed to walk along it, though it’s not unusual to see walkers and bikers. Although it looks calm enough, the channel is V-shaped and from 15 to 21 feet deep. It’s not particularly steep above the water line, but in places it can be slippery and the current is usually deceptively fast.

Frankly, there isn’t much to see and what you do see is fairly ugly.  It’s amazing to me the amount of plastic detritus I find in the wrack line. Much is unidentifiable plastic bits, but the majority is represented by plastic tampon applicators, followed by disposable lighters, prescription pill bottles, and ball point pens. People, quit flushing non-organic stuff down the toilet! I have also found, not once but twice, er, marital aids*.

Despite the general sterility of concrete, nature perseveres on the channel. Remarkable little ecosystems arise from the cracks and the accumulated debris.  There is also grassy and shrubby vegetation above the concrete banks, and some wooded patches on buffer property. In fact, the efforts of a few of us have managed to accumulate records for 154 bird species.

This stretch of the Rouge lies between two heron colonies, and they frequently fish along the river, as evidenced by this “graffiti.”

Other animals take advantage of vertical surfaces under overpasses to mark their territories.

And there is also evidence of them fishing in the river and creating their own little ecosystems.

This spring is the second wettest on record for Detroit; we’ve already had over 14 inches of rain in the last two months. Last week, the Rouge watershed had about 4 inches in one day. Here’s a typical view of the channel looking north from this point towards a large hotel.

And this was the view when the river crested on 26 May — well over the top of the concrete banks, something I have never seen.

And here is the view from the same overpass, looking downstream.

The river crested at over 5 feet above flood level. The argument could be made that the channel did its job, keeping water more or less within itself, and draining the watershed like a massive flume. On the other hand, just upriver on campus, the natural floodplain also did its job — the one nature intended. If more floodplain remained in the watershed, if far less land had been converted to concrete and other impervious surfaces, this much water would never make it to this point in the river, an enormous “flood control project” would not have been necessary, and a river would be just a little more free.

 

*Of course I have photos, and good taste is not one of my strong suits, but I think it’s best they remain unpublished. One has to wonder about the backstory, though. Both were inhumanly large (though not the inspiration for the title of this post) and probably could not have made it down the toilet. The first one was found in the general vicinity of an adult book store (the original 5th Wheel). It doesn’t take too much imagination — and you’d only want to partake in the minimum amount — to conceive a scenario on how it may have ended up nearby. We found it during a Christmas Bird Count, and took great delight in announcing it at the tally as “dicky bird sp.”  The second one, however, was quite a distance upstream. Further, it was sort of charred looking (a burnt weiner) and appeared thoroughly battered. Hopefully this was due to its arduous journey downstream from wherever it originated, and not [shudder]. Well, if that’s the most disgusting thing I discover urban birding, I’ll consider myself very fortunate.
