The blueback trout (Salvelinus alpinus oquassa), a rare jewel from the Maine woods. In the mid 1870s, they were thought to be competed out by introduced Atlantic Salmon and smelt. William Converse Kendall predicted they would be in other northern Maine waters in 1914, and they were found in 1948.

The figure is from "The Circulation of the Oceans" by Walter Munk. I found it in my guide to Oceans by Karl K. Turekian, 1968.

The pattern of clockwise ocean currents in the northern hemisphere and counterclockwise in the southern hemisphere can be explained by the westerly winds blowing W to E at 40°N and 40°S and the trade winds blowing from E to W just north and south of the equator.

I was rereading Tinbergen's "On aims and methods of Ethology" this morning and was awakened by this: "It seems to me that...we...will always need naturalists and observers as well as experimenters; we must...not discourage the [person] with a gift for observation."

I have the gift for observation.

The black bellied whistling duck (Dendrocygna autumnalis) is biparental with both sexes incubating the eggs and caring for the young. There are many records of unattended egg dumps and of up to 65 eggs in a single hole.
