‘You’re Invisible, But I’ll Eat You Anyway.’ Secrets Of Snow-Diving Foxes : Krulwich Wonders… : NPR
how does an above-ground fox catch an underground mouse? Well, the answer is nothing short of astonishing.
Remarkable video and conclusions. (A pox on anyone who would kill such a magnificent creature.) [via a favorite blog: https://www.southernrockiesnatureblog.com/
Southern Rockies Nature Blog: What Would a Mountain Lion Eat for Thanksgiving?
Deer, you say? That might be a good answer, insofar as a common formula is that an adult must eat a deer-size animal every week to ten days. But down on the Rio Grande north of Albuquerque, researchers at the Pueblo of Santa Ana Department of Natural Resources collared and tracked one male who specialized in badgers.
I wonder if the same people who hate coyotes also hate cougars.
Meet The Rare Sea Wolves Who Live Off The Ocean And Can Swim For Hours – Healthy Food House
McAllister explains: “We know from exhaustive DNA studies that these wolves are genetically distinct from their continental kin. They are behaviourally distinct, swimming from island to island and preying on sea animals. They are also morphologically distinct — they are smaller in size and physically different from their mainland counterparts.” Paquet maintains that these types of coastal wolves aren’t an anomaly, but a remnant: “There’s little doubt these wolves once lived along Washington State’s coast too. Humans wiped them out. They still live on islands in southeast Alaska, but they’re heavily persecuted there.”

Cacao came from a region 1,200 miles south of Chaco, so its presence at Chaco a millennium ago, as well as the discovery there of thousand-year-old parrot feathers and skeletons, indicates that the early Pueblo people who lived at Chaco were exchanging goods with their southern neighbors before the Spanish arrived around 1500.

The Moon brightens the evening sky this week, waxing toward the Full phase as she courses through the late autumn and early winter constellations. Full Moon occurs on the 13th at 7:06 pm Eastern Standard Time. December’s Full Moon is known as the Moon Before Yule in the skylore of European Christianity. Other names, such as the Cold Moon, Big Moon, and Long Night Moon, reflect the influence of Celtic and Native American lore. December’s Full Moon occurs near Luna’s most northerly declination for the year, flooding the winter landscape with her pale light. This year she appears a bit brighter than usual thanks to the Full phase occurring near the Moon’s close perigee, which falls on the 12th. On the evening of the 12th you’ll find the nearly-full Moon pass through the heart of the Hyades star cluster which forms the “face” of Tauris, the Bull. Watch Luna creep closer to the bright star Aldebaran as the evening passes. At 11:07 pm EST the star will wink out as the Moon’s limb covers it. You can see it re-appear at 12:21 am.
The Full Moon washes out the annual Geminid meteor shower, which peaks on the night of the 13th. This is normally one of the year’s most reliable showers, and under dark skies it usually produces one or two “shooting stars” per minute. The meteors are generally slower than the August Perseids, and the radiant, in the constellation of Gemini, is well-placed after around 10:00 pm. Bright moonlight will hamper the number of meteors that the average observer will see this year, but a patient observer may be able to spot 20 or so per hour, even from urban locations.
2016 Ends with Three Supermoons
Since the moon’s orbit is elliptical, one side (perigee) is about 30,000 miles closer to Earth than the other (apogee). The word syzygy, in addition to being useful in word games, is the scientific name for when the Earth, sun, and moon line up as the moon orbits Earth. When perigee-syzygy of the Earth-moon-sun system occurs and the moon is on the opposite side of the Earth from the sun, we get a perigee moon or more commonly, a supermoon!
This coincidence happens three times in 2016. On October 16 and December 14, the moon becomes full on the same day as perigee. On November 14, it becomes full within about two hours of perigee—arguably making it an extra-super moon.
The full moon of November 14 is not only the closest full moon of 2016 but also the closest full moon to date in the 21st century. The full moon won’t come this close to Earth again until November 25, 2034.
Full Moon occurs on the 16th at 12:23 am Eastern Daylight Time. October’s Full Moon is popularly known as the Hunter’s Moon. The geometry of the Moon’s path in the sky is similar to last month’s Harvest Moon, so the interval between successive moonrises around the time of Full Moon causes Luna to appear to rise at nearly the same time for a few nights. In September this phenomena was used by farmers to use the light of the rising Moon to help them bring in more crops. This month hunters have a bit of extra light to pursue game across the stubble of the harvested fields.
I’m linking to this capture the map by Catherine Gilman of these pre-Hispanic cultural areas. I have not heard of Patayan or Trincheras cultures.

[Aaron Wright is] also in the midst of applying for a series of grants to continue our research along the lower Gila River. These efforts are designed to expand our knowledge of the Patayan tradition, at least how it was expressed in southwest Arizona. Patayan is the least understood late prehispanic cultural tradition in the U.S. Southwest. Some may even claim that Patayan isn’t even a Southwestern archaeological tradition: don’t believe them! Granted, Patayan isn’t covered in our college courses on Southwest archaeology, but this is because little research has even been done on this aspect of the past.

Along the lower Gila, Patayan is expressed in fabulous geoglyphs and extremely dense galleries of rock art adorning black volcanic cliffs and weathered granitic boulders. It is also found among the dozens of villages sites strategically placed to harness floodwater from the lower Gila in order to irrigate crops of corn, melons, gourds, and cotton. Yes, I’m talking about sedentary agricultural villages. Are we to believe that the rock art and geoglyphs were crafted by phantoms? The lower Gila contains some of the best-preserved, and most of the only extant Patayan villages. This is because damming and extensive agriculture have obliterated much of the Patayan signature from the valleys of the lower Colorado River, the epicenter of the Patayan World.
The Sky This Week, 2016 August 9 – 30
Full Moon occurs on the 18th at 5:27 am Eastern Daylight Time…. August’s Full Moon is popularly known as the Corn Moon, Grain Moon, or Sturgeon Moon, indicating the time of year when crops mature for the harvest and fish return to their spawning grounds.
Full Moon occurs on the 19th at 6:57 pm Eastern Daylight Time. July’s Full Moon is popularly known as the Hay Moon, Buck Moon, or Thunder Moon, with the latter being particularly appropriate for this time of the year.
from The Sky This Week
Great stuff, as usual, from The Sky This Week.
This is a good week to try to make sense of the sheer scale of the cosmos as we have a variety of bright objects that we can look at and think of in terms of distance as well as brightness. The first thing we need to do is find a convenient “measuring stick”, and fortunately the laws of physics provide us one that’s good for measuring vast distances. Light, the essential “messenger” of all celestial objects, travels at a finite speed that amounts to about 300,000 kilometers (186,000 miles) per second, so if we can measure the time it takes light to reach us from an object we can gauge its distance.
When we look at the Moon, we see it as it appeared a just over a second ago. Light from the Sun takes eight minutes to get from there to here. The ruddy glow of Mars is five minutes old by the time it arrives here at earth. Giant Jupiter’s bright glow has taken 50 minutes to cross the gulf of space that separates us. … Our last bright planet is Saturn, and the view you’ll get of his wonderful rings tonight will take 77 minutes to get here. Far-flung Pluto, which marked the edge of the solar system when I was in school, is still relatively close-by, just under 4.5 hours at light speed.
Now let’s jump to the rising stars of the summer Triangle in the eastern part of the sky. Bright Vega, highest and brightest star of the trio, is located at a distance that takes light 27 years to cross! Altair, southernmost of the three stars, is even closer, a mere 16 “light years” away. Looking at the last, northernmost member of the triangle one would naturally assume that Deneb would be a similar distance from Earth, but here is where assumptions break down. Vega and Altair are relatively bright “normal” stars, but Deneb is a “blue supergiant” star that shines with the equivalent light of 100,000 suns! Its distance is some 100 times farther away than Altair, so the light you see from it tonight started its journey toward us when Constantine was Emperor of Rome. And we’ve barely ventured into the vast starfields of the Milky Way.
from The Sky This Week
From The Sky This Week: The Moon waxes in the evening sky this week, passing through the summer constellations along the southern reaches of the ecliptic. Full Moon occurs on the 20th at 7:02 am Eastern Daylight Time. June’s Full Moon is popularly known as the Strawberry Moon, Rose Moon, Mead Moon, and Honey Moon. Each of these names not only indicates something indicative of the month’s flora, they also refer to the warm tone that the Moon can take on a warm June evening due to her southerly declination. Look for the Moon a few degrees north of the bright star Spica on the evening of the 14th. On the 16th and 17th she accompanies ruddy Mars across the sky, and on the 18th she passes just over two degrees north of yellow-hued Saturn.
The summer solstice falls on the 20th at 6:34 pm EDT. At this time the center of the Sun’s disc stands directly over the Tropic of Cancer north of the Hawai’ian Islands. While astronomers consider this to be the first day of summer, many traditional calendars observe it as “Midsummer’s Day”, commemorating the year’s longest day. Here in Washington Old Sol is above the horizon for 14 hours 54 minutes. Add in the times of morning and evening twilight and the duration of astronomical darkness amounts to a paltry 5 hours 8 minutes. The farther north you go, the less the duration of night becomes. Cities such as Paris and London never experience total darkness at this time of the year, and places north of the Arctic Circle see the Sun above the horizon for a full 24 hours. The Sun appears to hover near the Tropic of Cancer for a week or so around the time of the solstice, and most of us probably won’t notice the changing times of sunrise and sunset until well into July.
