There’s Never a John McCain Around When You Need One

I invite — beg for, actually — comment on this story from the Miami Herald. Speculation on the author’s use of the word “fruitless” is appropriate, although obvious.

A new study of white ibises by University of Florida researchers suggests the pollutant could have a far more profound impact than imagined: It turned a good chunk of a captive flock gay.

The study, published online Wednesday in a biological journal, documented a number of changes in the mating behaviors and reproductive success of four groups of ibises fed varying levels of mercury over a three-year period.

By far the most surprising effect was on the courtship inclinations of male ibises. In the first year, 55 percent of the males given the highest doses of mercury in their feed hooked up with other males during breeding season.

“They pretty much did everything except lay eggs,’’ said Peter Frederick, a UF wildlife ecologist who led the study. “They built nests, they copulated, they sat in the nests together…’’

Some males exhibited bi-sexual interests, changing partners when male-on-male efforts proved fruitless. That’s a common response in the wild after failed efforts, Frederick said.
