COOTS FIGHTING & THE CARIBBEAN COOT DEFEATED
These coot fight images are from Phil Lanoue, whom I have featured before. He is a master of bird sequences, magicking a whole avian story or drama in a few clear, sharp photos. These types of image are well beyond my skills and my camera limitations. Here are 2 males battling over a female which, by the final aggressive image in which dominance is asserted, has disappeared for the picture…
The other battle in Coot World occurred in 2016 when the endemic Caribbean Coot (formerly Fulica caribaea) was defeated by the combined forces of the American Coot (Fulica americana) and the all-powerful AOU, official arbiter of bird categorisation. They are now joined as a single species, the differences between the two types being considered insufficient to warrant separate species status. The familiar American version looks like this (note the red area on the shield above the beak):
The ex-Caribbean Coot, has white frontal shield that extends to the top of the head. When I was compiling ‘Birds of Abaco‘ in 2013, there was already a question mark over the separate species status, with many regarding it as a sub-species of the American Coot. I wrote: “There is an intriguing debate, a small book in itself, about the existence as a distinct species of the Caribbean Coot, with its white frontal shield. Many field guides include it separately, some with the rider that it is ‘unrecorded in the Bahamas’. The Bahamas Bird Records Committee does not recognise it, and Hallett, among other experts, views it simply as an American Coot variant. The image below of the two coots together is included to illustrate the visible difference between the birds. The genetic debate is fortunately outside the scope of this book”. That said, I pigheadedly went ahead and included it as a separate species anyway…

The research that led to the reclassification was based on the fact that breeding biology suggests that different species favour their own species for breeding. Research by Douglas McNair and Carol Cramer-Burke indicated that there is little or no ‘reproductive isolation’ of the sort to be expected in different species. The coots had no particular preference in their choice of mate. Also, they sound alike.
