Big Year 2015

The old year closes tonight, and with it closes another chapter of Big Year birding.

This year, Charlie Lyon is leading the pack of contenders in an attempt to regain the lead he held for a decade. When Charlie competed against Mark Swan in the early 2000s, ground rules were followed to maintain a level playing field. The rules were based on the honor system because birders don’t have the wherewithal to document every species they see. Beyond the expected species, however, rarities that were claimed by competitors had to be documented and accepted by the Louisiana Bird Records Committee to see that they were accurately identified.  Obviously, included species had to be on the state checklist so that listers didn't pad their lists by claiming emus and Muscovies. Such ground rules are standard fare for Big Years to prevent confusion and disputes.

When Jay Huner was trying to set the Big Year record a few years ago, it became apparent that the number to beat was a matter of debate and that there was no checklist available to verify the number. That issue still hasn't been resolved.  Some of the birds in the claimed total of 356 aren't on the state list, and not all of the included rarities were accepted by the records committee. The obvious conclusion is that the current record is less than the originally reported 356.       

This year the same issue is in play and has to be dealt with because Charlie has registered a competitive figure—356 species.  However, Charlie’s total of 356 for this year as calculated by eBird is also artificially high because it includes at least two of the same non-checklist species (Canada Goose and Monk Parakeet) that the leading list contains. Charlie’s list also contains several rarities that need to be accepted by the records committee in order to remain countable.  Charlie understands that this process comes with the territory. 


The trick now will be to compare lists and see what counts and what doesn't.  

Competitors, feel free to submit your lists and comments.

2015: The blur that was.


In no particular order, images from a year I barely remember. But it was fun.

The "Canada" Goose Challenge


Below are pictures of "Canada" geese, both Canada and Cackling. Which are which? Read on. 


a. Cackling Goose and Greater White-fronted Goose. Cacklers can look small, but some are larger than Specks. The bill of this Cackler looks a bit long and thin here, but part of that is the light and lack of focus. Because of the variation in size, bill length, and changes in posture that can make some birds look long-necked, some Cacklers invite confusion with Canadas. 11 Jan 2009, Thornwell, LA. 

b. Ditto for Bird B. This Cackler looks large, but a close look at this small image shows a stubby bill and angled head. 11 Jan 2009, Thornwell, LA. 

c. This bird shows a stubby bill with slightly concave "droop" at the tip and a blocky head that identifies it as a Cackler. 20 Feb 2011, Cameron Prairie NWR. 

d. The curved and sloping head and long slender bill is a dead giveaway for a Canada. 6 Feb 2010, Wright, LA. 

 e. The blurry photo makes the bill look thin, but not long. The shorter bill, steep forehead, and angular peak in the rear crown show this to be a Cackler. This is the same bird as in Photo C, but note the different look in the different posture. 20 Feb 2011, Cameron Prairie NWR. 


f. All of these birds show small stubby bills and angled heads--obvious Cacklers. 11 Jan 2009, Thornwell, LA. 

g. This view of the same bird from Photos C and E shows the same stubby bill and blocky-headed look as the birds in Photo F. This bird was injured and often looked longer-necked than this as it stretched out its neck to pull itself forward; see additional photos at 
http://losbird.org/lbrc/goosebbb.htm. The long-necked look caused speculation that the bird might be a Canada Goose, but closer study proved that it was indeed a Cackling Goose. 20 Feb 2011, Cameron Prairie NWR.
