Month: February 2009

Stargazers willing to brave the cold and stay up until midnight or later will observe  a once-in-earth’s-lifetime event this month.  Possibly with the naked eye, and certainly with binoculars, they will be able to observe the newly discovered Comet Lulin on its trip through the inner solar system.  Lulin is named for the Taiwanese observatory where it was first seen in July, 2007.

Comet Lulin will look like a greenish fuzzy blob, with a very bright center, and probably a tail.  It will appear much bigger than a star.  It should be brightest on February 24, its closest approach to the earth.  At that time it will be half the distance between the earth and the sun–about 38 million miles– away and traveling at 31 miles per second toward the outer part of the solar system.

“Around 1962, when we were living on Lake Erie, my parents took me on a special trip to see an eagle’s nest, thinking it might be my last chance for such a sight,” recalls naturalist Michael Arduser. 1962 was the year that Rachael Carson’s book Silent Spring made the public aware that widespread use of the insecticide DDT was decimating the country’s bird population.  Eagles and other raptors were especially hard hit.

Fortunately, in the long run their fears were not realized.  Although the country’s bald eagle population remained very low for nearly twenty more years, around 1980 the tide began to turn. Since then the eagle population has been steadily increasing.  In fact, Arduser, who is with the Missouri Department of Conservation, reports that the state now officially has 150 pairs of nesting eagles.  He and his colleagues think the actual number may be close to 200, up from zero pairs in 1980.

In 1978, the federal government listed the bald eagle as ‘endangered’ in 43 states, and ‘threatened’ in the other 5 of the lower 48.  From about 20,000 estimated nesting pairs in 1800, by 1963 only 417 pairs remained outside of Alaska.

The possible extinction of our national bird spurred regional recovery teams to undertake intensive programs to bring the eagles back.  These efforts were so successful that by 1995 bald eagles removed from endangered list, and upgraded to threatened.  Numbers continued to grow, and in 2007, the American bald eagle was “delisted” by the U.S. Fish and Wildlife Service.  Bald eagles have doubled in number approximately every five years.

“The eagle’s recovery is a testimonial to the resilience of nature, and also to people’s willingness to recognize problems and correct them,” says Arduser.
