Common Knowledge: Loons are driven off lakes by boaters. The literature from the 1970s and 1980s makes it clear that there was a reduction in loon populations on lakes that were previously more isolated, and have become more accessible, and suffered greater amounts of boat traffic.

In fact, I just spent the last half hour watching Mom and Dad loon (whom I cannot tell apart, by the way) feeding Junior I and Junior II (whom I also cannot tell apart) what I have determined to be mostly crayfish, but also the occasional minnow.

edyong | February 23, 2009In late 2007, seabirds off the coast of California began to die in record numbers. The waterproof nature of their feathers and been wrecked, and they were soaked to the skin. Without an insulating layer of air trapped within their plumage, the damp birds were suffering from extreme cold. These are exactly the type of problems that seabirds face when they blunder into oil spills, but in this case, not a drop of petroleum had entered the water. The problem was a biological one.
At the same time, Monterey Bay in California was plagued by a massive "red tide" - a bloom of microscopic algae…
