The Jacanidae are an interesting assemblage of tropical water birds with
extraordinary long toes and claws which allow them to spread their weight
so they can walk on lily pads and other floating vegetation.
The name "Jacana" is actually a Portuguese language word based on the Tupi
Indian name for the bird. It supposedly should be pronounced Zha-seh-NAH
but very few people pronounce it that way.
See: http://www.birds.cornell.edu/crows/birdname.htm
A poll conducted by one web site found that most people pronounce it
Jah-KA-nah.

...but that is out of a sample size of only 66 participants. It is often
spelled Jaçana so the "c" should probably be soft.
My recommendation is to abandon this odious name entirely and use an
alternate such as "Lilly Trotter" or the more evocative "Lotus Bird."
The Northern Jacana is polyandrous with females defending territories that
may have multiple nests and multiple males who incubate the eggs and care
for the young.
They are very common at CATIE and we saw both adults and immatures. This
is an immature.
Three subspecies are recognized. This is the nominate southernmost
mainland race which ranges from Belize to Panama and which is sometimes
called the "Central American Jacana." However it differs from other races
in minimally smaller size and the three named races are doubtfully valid.
