A couple weeks ago I posted the Top 100 Most Reported Species in eBird in North America. It was data from all years 1900-2012 as of 2/22/2013. I actually summed up the total of all positive checklists for every species in North America reported to eBird (restricted to only species listed on the American Birding Association’s Checklist of Birds of the ABA Area). Today I am making a file available that lists all 932 ABA species reported to eBird during that time period. This is a CSV file (comma separated values) so you can download it and put it into most spreadsheets. Even if you do not have a spreadsheet, you can still view the file as a text file.
Have you ever wondered what birds were most commonly reported to eBird? I have collected data from eBird for the years 1900-2012 (all months/weeks) as of 2/2/2013. Data has been rolled up by State/Province for the Lower 48 States, all of Canada, and Alaska (but not Hawaii).
Yes. I know 2015 is almost here and this is data through 2012. But I’ve done all this in my “spare” time. I will update it when I get a chance. For now, I find this stuff still very fascinating. Oh, one other thing. This is still 2012 taxonomy, too.
The number of positive checklists (those checklists submitted indicating a positive sighting–either 1 or more birds) has been summed for each species out of nearly 6 million checklists. Want to know the species with the most positive checklists? The birds that are most commonly reported in all of North America? Here you go! Continue reading →
Yep. I am hitting the road again. Another 5,000 miles and lots of birds! I will be making some updates here, but hope to update Facebook & Twitter daily. I hope you will be able to follow me vicariously. And, for those of you in my path, maybe you can bird with me. Much of this itinerary is in flux–quite optional. I’m hoping to have some fun seeing and photographing birds along the way. I just got a PhoneSkope adapter for my iPhone and Swarovski telescope. This will be a good test and you all will be my Quality Assurance team to rate the pictures. And I will be eBirding along the way, too.

Macro trends? What??!!? Haha. I will get to that in a moment. It’s been a month since I last posted here. Sorry. In that month I drove from Colorado to Virginia for the Eastern Shore Birding Festival. I had a great time in Cape Charles, VA. I drove home to Ohio and worked for a week and then headed back south to North Carolina’s Outer Banks for the Wings Over Water Festival. It was a terrific week packed full of fun events and lots of birding. I worked last week and my schedule finally caught up with me. I was down a couple days with a cold. Ok. I still have a cold but I’m functional…sort of. When I finish this week I will drive to Massachusetts for Athol Bird and Nature Club meeting and some New England winter birds.
Greetings from Nebraska! I’m en route to Brighton, CO for the Rocky Mountain Bird Observatory’s BBQ with the Birds on October 5, 2013. I just had a great weekend at Pt. Pelee with the Ontario Field Ornithologists. More on that in another blog.
Previously I posted 2014 Target Birds 1-10 & 11-20 & 21-30. Today we will look at 31-40. These represent the most commonly reported birds in Panama in late January in eBird. I am using what eBird refers to as Frequency of Checklists. This is a number that uses the total number of checklists that have a particular species checked divided by the total number of checklists submitted. It is the percent of checklists that have reported this species. eBird data was accessed on 8/26/2013 to retrieve this list. Late January? Yes. This is to coincide with Wildside Nature Tours trip Panama Canal Zone and Pipeline Road Birding with Greg Miller, January 18-25. Ready for those target birds? Here we go:

Do you have a nemesis bird (or two)? Did you ever wish for a list of species with “Best Bets” for location & timing? Well. Here it is–the long-awaited Species breakdown for the Impatient Birder. The Top 10 Best Bets for over 900 species are listed in 6 PDF documents–they are split into 50-page segments. These documents are free for download. (but they are fairly large)

Most Frequently Reported Birds in Panama for late January #21-30
I hope you enjoyed the Top 10 Most Frequently Reported Birds in Panama in late January that I posted last week. Again, I am using eBird data for the entire country of Panama, the last 2 weeks for all years. There is not a ton of data, but it is way better than nothing! I am using data I collected July 13, 2013 (last month). And all of this is preparation for my trip to Panama January 18-25 with Wildside Nature Tours. You can sign up for the trip and come birding in Central America with me at this link: Panama Canal Zone and Pipeline Road Birding with Greg Miller
As I said before, some of Panama’s most common birds are birds that you will recognize from North America. Like this one:

Uh-oh. A little bit–ok, A LOT–of eBird geeky stuff lies ahead…
I spent the last few days wrangling some eBird data for the state of Ohio. I processed year list data for 10 individual years, 2003 through 2012. What comes next is me…tinkering with data I downloaded from http://ebird.org on 6/26/2013. eBird is a Citizen Science online project containing over 100 million bird sightings worldwide. And it is growing every day. eBird allows ordinary birders to enter their bird sightings online and stores them in a database. I downloaded data from this database into spreadsheets to create the final report available as a free download below in .PDF format.
A total of 32,307 checklists were submitted to eBird for the state of Ohio in the 5 years 2003 through 2007 representing 339 species. For 2008 through 2012, 97,837 checklists were submitted to eBird for the state of Ohio and a total of 357 species were recorded. The combined total number of species for the 10-year period 2003-2012 was 368 species of birds.
Of the 368 species, 274 species were recorded in each of the 10 years between 2003-2012. In fact 28 species were reported in every week for the entire 10-year period.
Of the 368 species reported, 241 showed an increase in % of checklists. In other words, about two thirds of these species were reported on a higher proportion of checklists in the second 5-year period than in the first 5-year period. Some of this may be attributed to the large increase in the number of checklists between the periods. But 127 species showed a decrease despite three times the number of checklists in 2008-2012.
The 10-year Difficulty Code is a number derived using the logarithm of the percent of checklists for a species for the entire 10-year period. So a Code 1 species is up to 10 times more common than a Code 2 bird. Likewise, a Code 2 bird is up to 10 times more common than a Code 3 bird. That same Code 3 bird is up to 100 times less common than a Code 1 bird. And when “common” is used, it isn’t true abundance. First, frequency of checklists is only the percent of checklists on which a species is checked as seen. Also, this represents what is submitted to eBird. Not everyone uses eBird so the data that exists there is but a sample of reality. Still, over 100,000 checklists represents a body of data that is quite superior to “I am pretty sure there are a lot less Canvasbacks in Ohio. I don’t see as many as I used to.”
I just finished this report and have not had much time to review it yet. But, I was so excited about it that I decided to make it available for others to look at it. I hope you find it as interesting as I did.

Northwest Ohio in May is…for the birds. No really. It is a very birdy place. It has been my favorite place to visit on the North American continent in May for more than 30 years. And I cannot wait to go back there again this May. It is home to one of the most amazing displays of bird migration. There are many migration hot spots in the East. Your home state probably has a few good areas. And maybe you have ticked all 37 species of eastern wood warblers that occur here in Northwest Ohio, seen all the thrushes, tanagers, buntings, and orioles (and many, many more species). So why visit Biggest Week? Aren't there huge crowds of people? Isn't it hard to find lodging and places to eat? Can't I see all those birds somewhere else? Even if you have all these birds, you should visit this area of Northwest Ohio at least once in your life and experience it for yourself. Yes. There are huge crowds. But with a little planning and patience, your experience should still be unforgettable–even if you don't enjoy big crowds. For lodging and food you should also plan ahead or you will find yourself 30 minutes (or more) away from the comforts and conveniences “civilization”.
