American Sports Championships

We here at Mercenary Ornithology sometimes dabble in other subjects.  With the NBA and NHL playoffs starting, we decided to take a look at how long each North American city’s championship drought is for the four most popular sports (Football, Baseball, Basketball, and Hockey).  We gathered our data from Wikipedia and included all years for each sport starting with the first year its current championship format was created (1903 – MLB World Series, 1927 – NHL Stanley Cup, 1950 – NBA Finals, 1965 – NFL Super Bowl).  Note: the championship is noted in the year it occurred in with the exception of the NFL, which is considered to have occurred the previous year (as that’s when most of the games were).

Current Championship Droughts for North American Cities

A few notes on data analysis:

-Minneapolis and St. Paul have been lumped as “Twin Cities”.

-Strike/Lockout years do not have a champion, but DO add to the number of losing seasons. Luckily there weren’t too many of those, but the numbers are slightly off.

-I’m sorry, Cleveland.

-New Jersey teams with “New York” in the name were considered to be New York teams.

-Sorry Canada, I didn’t include Grey Cup victories.

Perspective on the Californian Drought

The fabled El Niño is upon us, and it has been raining in California lately. A LOT. To illustrate, here is a graph of the water levels (as provided by the USGS) at the reservoir in Bridgeport, CA over the past year. (I chose the Bridgeport Reservoir because I used to live near there, and I have a personal connection to the place, but the patterns I’m illustrating are true of many reservoirs across the western US.)

1 Year Reservoir Storage

However, I want to remind people not to be too quick to celebrate. If we consider a broader perspective and look what how much water has been in the reservoir over the past twenty years, what we see is not so encouraging. Water levels are still near the lowest recorded during that period.

20 Year Reservoir Levels

California has done an amazing job changing their water usage during the drought. Bay Area residents successfully reduced their water consumption by over 20% since the beginning of the drought, and statewide there has been a 13% reduction in residential water use. However, we need to continue being mindful of water resources. The bountiful rains of El Niño do not mean our problems are solved yet.

Have We Reached Peak Attenborough?

David Attenborough actively attenboroughing

David Attenborough actively attenboroughing

David Attenborough has been influential to my life in many ways. He inspired me to become an ornithologist and his documentaries are what gave me the comfort and solace I needed to finish my degrees in ecology with some semblance of sanity left.

While on recent extended spree of documentary watching (which might speak to my current mental state, but we won’t get into that), I noticed that it seems like the older Attenborough gets the more prolific he becomes. In 2015 alone he wrote and narrated three episodes of Conquest of the Skies where he discusses the evolution of flight, a documentary called Paradise Birds, six half-hour episodes of Natural Curiosities a program where Attenborough delves into the history of our understanding of the natural world, and narrated seven episodes of The Hunt and four episodes of Wild Canada. Two new programs are already announced for 2016.

Of course, I needed to test this hypothesis empirically. Is David Attenborough becoming more productive as a writer and a narrator through time? I looked at the 63 years of documentary films he has made to find out if this is true. In exploring this question, I also learned the disturbing fact that in the early 1970’s we almost lost David Attenborough the natural historian and might have found ourselves in a reality where instead there was only David Attenborough the executive. These graphs tipped me off to the fact that there exists a parallel universe without The Life of Birds where I am not an ornithologist but instead a statistician or a drug addict (or perhaps both).

Attenborough2HoursAsNarrator

Hours of documentary film narrated by David Attenborough released each year.

Attenborough2NumberofDocsWritten

Number of documentaries or documentary series’ episodes written by David Attenborough released each year.

As you can see, my original hypothesis appears to be correct in terms of narration. Using a linear regression model, we find that as the years progress, the total hours of film where David Attenborough acts as the narrator or presenter is increasing significantly (R2 = 0.53, F(1, 61) = 70.8, p < .0001). As of now, you could watch 23 straight days of David Attenborough’s documentaries without re-watching anything (assuming you can find all of his work, but some of it seems to have been lost to time). As a writer, his work has remained more consistent through time with him writing a new major series once every few years or so with smaller projects interspersed in between. We see no significant trend in productivity as a writer over time (R2 = 0.025, F(1, 61) = 70.8, p < .113).

In both writing and presenting, however, there is a noticeable gap in his work as a documentarian in the late 60’s and early 70’s followed by a sudden spike in 1973. I looked up a biography of David Attenborough to see if I could find an explanation for this, and I discovered that this is the point where we nearly lost Attenborough as we know him. In 1965 David Attenborough took a job as controller of BBC2 then in 1969 he became director of programs for both BBC1 and BBC2. 1973, where the graphs suddenly spike, is when he resigned from his prestigious position and returned to being a natural historian. (He did what so many people can never bring themselves to do; to turn their back on a “good job”, a position of importance and power for something different.)

This is not to discount his accomplishments at the BBC. He introduced color TV to the UK through The World About Us and was responsible for signing Monty Python’s Flying Circus. However, he has given so much as a naturalist and writer, and I don’t want to be in a world without that. I hope he keeps making documentaries and this positive trend continues. I’m not ready to see peak Attenborough yet.

To create these graphs, I needed to track down a comprehensive 
filmography of David Attenborough’s work, which proved to be 
more difficult than expected. Project Gutenburg and IMDb have 
good but incomplete records of what Attenborough has contributed 
to. I also incorporated information from miscellaneous sources 
like filmhistory.org, the New York Times movies and television 
section, amazon.com, and PBS NOVA’s website where there are records 
of shows not mentioned in my two main sources. Information about 
some of his most groundbreaking work like “The World About Us” is 
lacking; of the nearly 500 episodes made, he narrated about 50, but 
I can’t find anywhere that says when or for which. For situations 
like this where he was an occasional narrator but more detailed 
information is missing, I assumed his narration was roughly evenly 
spread out through the life of the series. For some of his older 
programs where there is no information about the length of the show, 
I assumed 30 minutes per episode because that was the typical length 
of his other shows produced in that era. In trying to compile a 
complete list of his work, there are still probably programs I missed.

From the Brink: The Return of the Canada Goose

CANG

Average number of Canada Geese per Breeding Bird Survey route in each U.S. state over four year intervals (map made in QGIS).

On April 1, 1963, the U.S. Fish and Wildlife Service issued a press release with the title, “GIANT CANADA GOOSE, LONG BELIEVED EXTINCT, REDISCOVERED IN MINNESOTA”. It was not an April Fools joke. Due to hunting pressure and loss of habitat, the subspecies of the Canada Goose that lived in the eastern United States had been nearly wiped off the face of the planet.
