Do Mother Hummingbirds Sleep?
Hummingbirds have voracious appetites, eating the human equivalent of an entire refrigerator full of food every day. Even sleeping hummingbirds have huge metabolic demands that must be met to survive the night. They conserve energy by going into nightly torpor, drastically lowering their metabolic rate and body temperature. The hummingbird behavior shown here is torpor, and is no cause for alarm.

But can nesting females incubate their eggs well using torpor? A group of researchers, including LMU’s Center for Urban Resilience, aim to find out by using remote thermal sensing technology to run a comparative analysis between multiple nests in different micro environments. Hummingbirds provide an optimal species for study of the physiological mechanisms animals use to cope with extreme limitations. And a better understanding of these mechanisms may have broader application in medical technology.
If you wish to help, the project leaders are crowd-sourcing the purchase of equipment needed for the study, with a goal of $4900. [Jane Beseda]
Sharing Venice Beach with Least Terns
People, crows and Least Terns are learning to be good neighbors at the Least Tern nesting enclosure on Venice Beach, thanks to research led by the LMU Center for Urban Resilience (CURes), and the efforts of local citizen scientists. We all use the beach in close proximity to each other because the enclosure is the only stretch of sand that is not groomed between Santa Monica and San Pedro.
The North American Waterbird Conservation Plan lists Least Terns as a Species of High Concern, so helping to preserve their nesting habitat is an important element in reversing their steep decline. CURes is also studying how to mitigate crow predation of eggs and chicks to boost survival rates at the enclosure.
Full Beaver’s Moon & Supermoon! Update – November 14, 5:52 AM PST
Here’s another update from SMBAS Blog on that large, disc-like, shining object which has frequently and mysteriously appeared in our nighttime sky this year (known to the cognoscenti as the moon).
Full Beaver Moon, Nov. 17, 2013

Nov. 14, 5:52 a.m. PST — Full Beaver Moon. Now it is time to set beaver traps before the swamps freeze to ensure a supply of warm winter furs. Another interpretation suggests that the name Beaver Full Moon comes from the fact that the beavers are now active in their preparation for winter. This full moon is also called the Frosty Moon.
November 12, 2016 moon, approaching full supermoon status (Jim Kenney)
This is a Supermoon (or perigee moon or perigee-syzygy), because the full moon is at perigee (closest point to earth) on the day it rises. It will also be the closest – 221,524 miles – it’s been since January 26, 1948. It will almost certainly be the brightest and largest full moon of your lifetime. Don’t miss it. The night of the 13th or early morning of the 14th are the best viewing times. This supermoon will appear 14% larger and 30% brighter than do full moons at apogee (farthest point from earth).
Effects on the high and low tides will be dramatic, and if there are any coastal storms nearby, batten down the hatches and watch out for flooding. Such extreme tides are called “perigean spring tides” with reference not to the season “spring,” but to the German springen “to spring up” or “arise.”

Chinese: White Moon; Celtic: Dark Moon; English Medieval: Snow Moon
Dakotah Sioux: Moon when horns are broken off
The Old Farmer’s Almanac has a page for each full moon, which has tips on times to harvest, fish and set eggs, things which every Los Angeles Westsider worth their salt must know. The best days for setting eggs are the 15th & 16th. Now you know, so you have no excuses.
Note: Pacific Daylight Time started March 13, 2016 at 2 AM (becoming 3 AM) and ended November 6, 2016 at 2 AM (becoming 1 AM). But you knew that.
The next significant full moon will occur on Dec. 13, 4:05 p.m. PST. Keep an eye on this spot for additional late-breaking news on this unprecedented event.

Halloween Celebrated at Butterbredt – October 29, 2016
A pair of Jack-O-Lanterns (Roxie Seider 10-29-16)
This year, the weather was warm and it seemed as though the migration was not yet occurring since the number of birds were down. The rabbitbrush was blooming but was not quite at the height of bloom (they’d be at their best in another week). On the drive to the spring, we saw a Greater Roadrunner actually flying across the road instead of running. It’s always a shock to see Roadrunners fly (or Soras for that matter). On the walk down the dry riverbed we came across the Horned Owl. It’s bit of a contest for who can find the Horned Owl first. Somehow someone always does even when we have almost lost hope. Found the Ruby-crowned Kinglet and of course lots of White-crowned Sparrows. Not a common bird at this spot was the Sharp-shinned Hawk.
Covey of California Quail (Roxie Seider 10-29-16)
Back at Keith’s home, we were carving pumpkins while California Quail kept themselves busy eating the bird seed that Keith always supplies for them.

Of course everyone stopped carving when someone spotted a couple of Red-breasted Sapsuckers. After dark, we lit the pumpkins and Chuck Bragg awarded each person with a prize.

Butterbredt never disappoints anyone. The air is clear so the color of the birds are much brighter and there is that quality of relaxation the desert inspires. If we get some good winter rains, the flower show in the spring (our April 30 trip) will be absolutely fabulous. [Jean Garrett]
