Maggie's FarmWe are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for. |

Friday, February 20. 2009Rethinking Plate TectonicsWhen the Dylanologist took his Geology 101 back in college he was taught, just as everyone else has been since the mid-1960s, that the process of plate tectonics (or "continental drift") explains the arrangement of the continents and the obvious matching coasts of Africa and South America. The continents were at one point all stuck together as Pangaea, and then, for some reason, they split right down the middle and were pulled/pushed apart from each other, riding right over ocean crust. Yet, what we were never shown was this map, which shows that nowhere on earth are there seafloors older than 180 million years (blue is oldest, red youngest; by contrast continental rocks date back nearly 4.3 billion years). Not only that, but the fastest rate of spreading is in the Pacific, which is presumed to be shrinking from both sides.
Geologists explain this conundrum by saying that all of the older seafloor has been "subducted" under to continents, and has vanished without a trace. Yet what is driving this activity? Are the ridges pushing the continents apart, or are the subducting seafloors pulling the ridges apart? If the push force is the driver, why is there so much spreading in the Pacific? If the pull force is stronger, how did spreading start in the first place between two connected continents? Geologists themselves don't have a good answer, admitting that they have no clear explanation, and physics suggests that neither force is anywhere near strong enough to cause entire continents to slide across the planet, or to build up huge mountain chains. What if the answer is much simpler? What if there is no seafloor older than 180 million years because, 180 million years ago, there was no seafloor? We know that sea levels were far higher than today 100 million years ago, covering much of North America (hundreds of feet higher than they would be even if all today's ice caps were to melt). There are fossils of extinct sea creatures which lived 200 million years ago high up in the Himalayas. In the Cambrian, it is widely accepted that virtually all of North America was submerged. Before 450 million years ago, we have no evidence for any life on land, despite the fact that life had existed for over 3 billion years at that time. Did life take 3 billion years to move to land? All of this implies that the earth may have grown in size, and that the linked lines of seafloor expansion on the map above, rather than being pressure points pushing out, are simply the places where a growing earth has cracked the outer crust and is filling it in with new material. Ed note: In science, the truth is always a moving target. Science is all about theory du jour, not Truth. Religion is about Truth, but science is about theory-making, theory-testing, and theory-changing. Every theory is supplanted, eventually. Scientists know that. Theory-imagining is what makes science creative and fun - an art, in many ways. There never will be any such thing as "settled science."

Wednesday, February 4. 2009Name that duckThe one in the air, not the Canvasbacks in the water. Photo from the Ducks Unlimited 2008 members' photo gallery.
Saturday, January 31. 2009Winter RobinsOccasional commenter and blogger Retriever sent us this photo of American Robins eating old rotting apples last week, in Massachusetts. People talk about the first Robin of Spring, but these woodland thrushes, who like fruit and berries, winter in almost every state in the US. They are migratory (Turdus migratorius), so our winter birds here probably breed in northern Canada. They all go south, but only so far. The cold doesn't bother them at all, nor does global cooling.
Tuesday, January 27. 2009Winter WaxwingA reader sent a nice photo of a Cedar Waxwing in an apple tree in Lenox, Massachusetts, taken this past weekend. These birds can be seen in every state in the US either as breeders, migrants, or over-wintering. These are usually flocking birds, and fruit is their favorite food. They have been known to get drunk or die from eating rotten, fermented fruit. They will roam the countryside all winter, stripping trees and vines of their remaining fruits and berries. That's why you will never see them at a bird-feeder. You can read about this elegant songbird here. Interesting detail: the orange at the tip of the tail indicates that this bird ate plenty of Japanese Honeysuckle berries (an invasive alien species) when those feathers were growing.
Sunday, January 25. 2009Duck of the Week: CanvasbackThe "Can" is probably the most sought-after duck for hunters (but I know I have described Mallards and Black Ducks similarly). Not only is his 60 mph flight a challenge, but he is considered the most tasty duck at the table. He is probably tasty because, despite being a diving duck, he prefers plant material. He's fairly large, too. He breeds in the West and Northwest up through Alaska, but winters all along the Eastern Seaboard. You can read about them here. Gwynnie took this photo of a male Can in breeding plumage on Saturday in CT. The sloped head is diagnostic, even in poor light. I suspect that he used a long lens:
Friday, January 16. 2009January birdsIn the snow and cold (13 degrees F yesterday morning, 9 this morning), we had hungry Gray Squirrels but not much of a variety of birds: Cardinal, Chickadee, Blue Jay, Mourning Dove, Song Sparrow, English Sparrow, Red-bellied Woodpecker, White Throated Sparrow, SC Junco. Boring. The problem is the rats at night, picking up the cherries fallen off the plate, as it were. It gives some fun for the pup, though. But you hate to get licked on the face by a pup who just ate a rat. Our Great Horned Owls need to get busier. I hear them at night. They like it here in the winter. Lots of rats. I think they ate most of the bunnies already.
Monday, January 12. 2009Name that birdIn the interest of improving the bird interest among our readers, a reader took this photo this week of these hardy shorebirds on the CT coast, not yet in their breeding plumage. Can you name it?
Wednesday, January 7. 2009A bad-ass Texas rabbitMonday, January 5. 2009Gull du Jour: Ring-billed GullA reader took these photos this weekend on the CT shoreline. That is the common Ring-billed Gull (sometimes known as the Parking Lot Gull), an inland, fresh-water breeder. They head for the coasts when the fresh waters freeze up.
Gulls take seveeral years to reach maturity and to earn adult plumage. These, I think, are second-year Ring-billed gulls hunting in the surf. First year birds would have a darker brown plumage:
And a good portrait:

Friday, January 2. 2009Hooded MergansersTwo males and a female, in their breeding plumage already. A reader in CT took this shot on the 31st on a stream-fed pond in southern CT. (No idea why it isn't frozen over. Maybe brackish.) You can read about the fine Hooded Merganser here. I don't shoot Hoodies, but I know folks who will shoot the males for mounts. I think a photo is better.
Wednesday, December 31. 2008Who ate my sparrow? (photos)From my window, this afternoon:
More photos of this happy bird below the fold. Editor: Darn nice pics, Gwynnie. Given his hunting success around your bird-feeder, he'll be back often. My diagnosis is in the comments, so folks can make their own minds up first. Continue reading "Who ate my sparrow? (photos)"

Monday, December 29. 2008Red Tail
They usually miss them. This guy came out of nowhere, fast, like an Israeli jet. Nature red in tooth (?) and claw. Those squirrels are over-fed and full of juicy fat. Happy dining, pal. Now I wish the Sharpies would pick off the rest of my pesky English Sparrows.

Wednesday, December 24. 2008A Cold Winter, and Christmas Eve Birds
Long Vs of Canada Geese have been honking high overhead all week, heading south, fleeing the snow cover in search of open fields for grazing. It's a sight and sound to lift anybody's spirits. All we have at the bird feeders now are White Throated Sparrows, Juncoes, Mourning Doves, Cardinals, Black-capped Chickadees, and Blue Jays. Kinda dull at the bird welfare office here, but we are always glad to help out at Christmastime. I did see one shivering Mockingbird. Where are the Goldfinches and all of the interesting sparrows? Even our semi-tough Carolina Wrens seem to have taken a hike south. I think they are all fleeing global cooling and sitting on lawn chairs in patios in Key West, sipping Rum Punches. If they weren't bird-brains, they would stay there.

Monday, December 8. 2008Our Ducks Unlimited EventRegular readers know that Maggie's Farm is a big supporter of Ducks Unlimited, one of the major conservation organizations in North America. The 1,000,000 members of DU now protect over 12 million acres of wildlife habitat. That is a heck of a good cause. We like to have fun, too, while raising $ to protect habitat. I took some photos of our annual event (which is mainly a boy's-night-out). Our raffle girls (with their scary boss on the left who insisted on joining the photo): More photos on continuation page - Continue reading "Our Ducks Unlimited Event" Wednesday, December 3. 2008Free lunch for migrating hawks

Monday, December 1. 2008Dog of the Week: Red Fox
Then we saw the fox. They must have moved in recently. The diminutive Red Fox is the most widely distributed predator in the world, from Asia through Europe and North America. (Yes, he is a Fox and she is a Vixen.) While our American Red Fox is likely a descendent of foxes imported from England for hunting, there was a pre-existing Red Fox here which inhabited boreal regions of North America. In the US, they are hunted with horses and hounds, but I don't know anyone who shoots them for fun. In the UK, our cousin Mr. Free Market loves to blast them, but he is a deeply disturbed individual (like all Capitalist gun-lovers), and he also tries to protect his pheasants. I tend to feel happy when I see one, which is not often, at dawn, trotting across a meadow. I think I have liked them since Roger and the Fox was a favorite of mine around age 6. They are increasingly semi-suburban, but are basically a rural animal. These nocturnal handsome bushy-tailed guys are mainly mouse, fruit, and bug-eaters, but they have been known to steal a chicken or young pheasant. Both coyotes and wolves will kill foxes. A bit about their range and natural history here. More here.

Monday, November 24. 2008BrantA flock of Brant ("Brent" in the UK) over Long Island Sound this weekend. Thanks, reader.
Thursday, November 20. 2008Ancient turtleWell-preserved Jurassic turtles found on Skye. They call it a missing link between land and aquatic turtles. Today, we still have many species that do a little of both, like North America's wonderful Wood Turtle, which swims and hikes. Tuesday, November 18. 2008Rodent of the Week: He is smarter than I am
I think it's been a long time since American kids went out with their .22s to get a mess o' savory squirrel in the oak trees for the family stew-pot. Like everybody else around here, my main problem with these crafty acrobats is that they eat me out of house and home on my bird-feeders. (Plus, these sneaky little terrorists almost blew me up when they chewed through the hose of my grill's propane tank.) The ongoing war of brains continues at Maggie's Farm and, thus far, the Grey Squirrel still wins. Here's some advice on Squirrel-proof bird feeders. Wki has a good summary on the Eastern Grey Squirrel. Here, we have the black version too, but not many.

Wednesday, November 12. 2008Duck du Jour: The American Black Duck
Unlike most dabbling ducks, Blacks are happy breeding on either freshwater ponds and marshes or in salt marshes. Some studies in recent years indicate a significant reliance on beaver marshes for breeding habitat. You can read about the American Black Duck here. Photo from that site.
