What Monarch Butterflies Need | Los Angeles Times

You can Guide Monarchs Back to their Throne
Numbers in the West have Plummeted. Here are 7 Things Gardeners Can Do.
New York Times | Jeanette Marantos | 27 February 2021
The Los Angeles Times had a full-page article on Monarch Butterflies in their Feb 27, 2021 Saturday section. If you’re at all interested in Monarchs – how are they doing, what’s good for them, what’s bad, and so on — I highly recommend it. You’ll almost certainly learn something new. Click on the link above.
If you’re not sure you want to read the original, I’ve listed a few factoids and excerpts below. Perhaps they’ll pique your interest and you’ll read the original. There’s a lot you can do to help the Monarchs, and they really need our help.
Monarchs breeding in the western U.S. migrate to coastal California. They overwinter in a few locations from Mendocino to Baja. They don’t go to the central highlands of Mexico.
They’re on the verge of extinction. Habitat destruction, insecticides, herbicides — and our good intentions, all contribute to their vanishing.
Eastern Monarchs dwindled from 384 million in 1996 to 60 million in 2019 — an 84% decline. Western Monarchs dropped from 1.2 million in 1997 to 30,000 in 2019 — a 97.5% drop. The 2020 24th Western Monarch Thanksgiving Count yielded only 1,914 butterflies total — a 93.6% drop from the prior year.
Pacific Grove, a famous Monarch Winter sanctuary, saw a decline from 45,000 butterflies in 1997 to none in 2020.
The showy Tropical Milkweed (Asclepias curassavica) you have in your yard may be killing them. Most SoCal nurseries have only tropical milkweeds, which bear feathery purplish-green leaves and deep orange flowers.
Tropical Milkweed doesn’t die all the way back during winter in SoCal, as does native milkweed. That permits protozoa parasites (Ophryocystis elektroscirrha) to multiply on the plants. When the caterpillars hatch, they eat the protozoa along with the leaves. Scientists believe that when a caterpillar eats too many such protozoa, it sickens and weakens the adult monarchs, interfering with their migration patterns, mating success, flight ability and lifespan. Milkweed blooming during winter may also disrupt their migration patterns.
Travis Longcore of Los Angeles Audubon Society and Urban Wildlands Group says that cutting tropical milkweed right down to the ground and keeping it trimmed until April will kill any overwintering parasites.
Here’s seven things you can do, with complete explanations in the LA Times article:
- Grow Native Milkweed
- Make Sure It’s Organic – they won’t have systemic pesticides in them
- Lobby Your Garden Center – to carry Native Milkweed, not Tropical (or Mexican) Milkweed
- Plant Lots of Nectar Flowers – the butterflies eat nectar, caterpillars eat only Milkweed leaves
- Don’t Try to ‘Rescue’ Monarchs – raising them indoors doesn’t help
- Keep an Eye Out – The Xerces Society wants photos
- Don’t Use Pesticides or Herbicides
All data below is from WesternMonarchCount.org
The Western Monarch Thanksgiving and New Year’s Counts are the product of annual monitoring efforts by volunteer community scientists to collect data on the status of monarch populations overwintering along the California and Northern Baja, Mexico coast (and a few sites from inland areas of California and Arizona). Thanks to the extraordinary efforts of these volunteers, we have 24 years of data demonstrating that monarchs have undergone a dramatic 99.9% decline in the western U.S. since the 1980s. The data collected by volunteers are compiled and entered into the Xerces Society’s Western Monarch Overwintering Sites Database which also includes many historic counts and survey efforts. Contact wmtc@xerces.org if you are interested in obtaining a copy of the entire database.
In 2020 only 5 of these sites were surveyed and no Monarch were found

The palm cockatoo is thought to be the only bird species to use tools musically – drumming wood to attract a mate.
The largest cockatoo and the largest member of the order of parrots is found only in Australia and neighboring New Guinea. The species is facing a dramatic population decline, scientists say.

Oystercatchers at Malibu Lagoon, 22 February 2021
[Posted by Chuck Almdale]
The weather really was perfect. The temperature started at 65°F at 9am, rising to 74°F by 11:30. A slight breeze rose as the day warmed, keeping it very pleasant. We never needed to add or shed clothing. While descending Malibu Canyon Road we saw a light brown haze stretching south from Santa Monica over the bay, but at sea level we couldn’t see it, and the sky was a cloudless pristine blue.
Low tide and high water at Malibu Lagoon (L – L. Johnson 2-22-21, R – G. Murayama 7-31-20)
Very few, if any, surfers graced the water. Tide was very low, heading lower to -0.13 ft. at 1:14pm. A high-pressure zone in the desert was blowing from land to sea, hence the smog layer. When there’s little swell, such winds flatten whatever waves there are. I saw one paddleboarder over by the pier.

There were seven birders, all masked – save for one nose – and ready to bird. Bring ‘em on!

Well…we had a good variety of ducks, a fair number of gulls and good diversity but low counts of shorebirds, but the passerines were conspicuous by their absence. Not even a mockingbird!

I would not be surprised to find at least two pair of Canada Geese nesting this spring at the lagoon. They seemed to quite like the easternmost sand & brush island – one pair at each end – but last month a pair seemed to be very interested in the area near the “osprey perch” at the western island’s east end. With eight geese honking and fighting, if they pair up there’s plenty of room.
By the time we got to the ocean, the tide was really, really out, with perhaps more rocky reefs exposed than I’ve ever seen before. [I have a sneaking hunch that I think this every time the water is really low.] Back home, I checked to see how accurate this memory is. Not bad, as it turned out. During the exactly 200 visits since 6/27/04, there have been only 17 dates with negative tides, the lowest being -1.10 ft on 4/23/13 (on-line table now says -1.06 ft). So…today’s -0.17 ft. was not the lowest, but not far off.
The high offshore rocks near the Malibu Colony had an assortment of cormorants – five Brandt’s among the Double-crested, plus a sleeping Harbor Seal at the other end, well away from the potentially noisy and annoying birds. Several of the Brandt’s had breeding-blue gular pouches and white cheek plumes. These birds usually leave about the time they develop these features, so we don’t see them every year.

The most interesting birds were the oystercatchers – three Black and one not-Black. They were all out on the exposed rocky reefs among the gulls. The three Blacks even left the rocks and ran around on the sand, unusual for Oystercatchers. One even took a bath in the waves with a gull. Quite astonishing!

I wrote a long blog in March 2020 about the oystercatchers at and around Malibu Lagoon so if you want to know everything I know about them, read it here. It’s a tricky call. “Frazar’s” American Oystercatcher breeds around the Sea of Cortez and on the west coast of Baja, and they look very much like our bird here. Black Oystercatchers also breed on the west coast of Baja and will hybridize with the Frazar’s. They do not hybridize with Frazar’s breeding around the Sea of Cortez. In Southern California we can have four types of Oystercatcher: Black (by far the most common), full American (least common, coming from Gulf of Mexico), Frazar’s (either side of Baja), and hybrid Frazar’s/Black (west coast of Baja).
Hybrid Oystercatcher or American “Frazar’s” Oystercatcher (H.p.frazari) — a close call.
The stance of the right-hand bird reminds me a bit of Mae West. (All 4 photos C. Tosdevin 2-22-21)
A bird rated 30 or higher on the the Jehl Scale is supposed to be an American. I rate this bird overall 28-33 of 42 points. Some criteria are difficult to impossible to see. Upper Tail Coverts – 2-3, Tail – 2, Chest – 3, Belly – 6, Under Tail Coverts – 3-4, Thighs – 4, Greater Secondary Coverts – 2-3, Extent of Primary Wing Stripe – 1-2, Underwing Coverts – 2-3, and Axillars – 3. The Jehl Scale is given at the end of the March 2020 blog, and can be downloaded or printed here.
This bird, in my inexpert opinion, is on the borderline between Hybrid and H.p.frazari. I feel it ought to have a bit more white going up the shoulder between black breast and wing. I also think this is one of the birds in the March 2020 blog, which I couldn’t reach a firm conclusion on. It probably spends most of it’s time along the wet rocky areas within a few miles of Malibu, and drops in at Malibu when the tide is low.
Two Western Snowy Plovers (L – R. Juncosa R – C. Tosdevin 2/22/21)
I waded across the outlet stream, opting for wide and shallow rather than narrow and deep. The water rose halfway up my shins — more where the sand was very soft and I started sinking in. Icy cold! I though my feet had fallen off by the time I got across. The point of crossing was to search all areas for Western Snowy Plovers which we hadn’t seen on our trip down the wide beach. Of course there were none. Back across the stream and westward we walked, finally finding 27 birds in their little sand-pockets, inland of the berm.

A magnetic field reversal 42,000 years ago may have contributed to mass extinctions | Science News
[Posted by Chuck Almdale]
The topic of reversals of the Earth’s magnetic field has interested me for over 50 years. In the 1920’s it was discovered that some volcanic rocks were magnetized with polarity opposite to the local magnetic field. In the 1950’s, when research vessels were taking core samples of the floor of the Atlantic Ocean, they discovered that magnetic polarity of the sediments ran in north-south bands, and occasionally the polarity reversed.
This led to the theory that the sea floor is spreading out in opposite directions from the Mid-Atlantic Ridge, that “new rock” emerges at the ridge, that the earth’s crust is made of large continent-sized plates which “float” on underlying mantle rock, emerging in some places and diving under other plates in other places. The ensuing science of Plate Tectonics leapt to the forefront of geology, while the phenomenon of magnetic field reversals stayed in the background, useful for measuring crustal movements, but not much else.
When the Earth’s magnetic poles reverse, the field strength dwindles (at an unknown rate) to the zero point, then builds back up but with the north pole now at the south and vice-versa. What we currently call the “north magnetic pole” is actually the Earth’s magnetic south pole, and vice-versa for the “south magnetic pole.” Check the diagram below. I presume, but feel free to check elsewhere, that when our magnetic poles next flip, our compass needles will all point south.
For me, it’s this dwindling and zero-point of field strength which is of interest.
From Magnetic Field of the Earth
Our magnetic field protects us from incoming charged particles — cosmic rays — by deflecting them magnetically. Decrease the field and more cosmic rays come down to the surface. At the zero point of field strength, there’s only atmospheric gas molecules to stop them. In the 1960’s I learned that such charged particles are important causes of genetic changes, i.e. mutations. These protons, etc. come whizzing in from outer space, bang into our DNA molecules, knock a base pair or two around, and if it happens inside a spermatozoa or ova, the animal or plant born with that change is a mutant.
Many such mutations have no physiological affect whatsoever, causing only “genetic drift.” Many others are detrimental — with complex creatures, it’s easier for things to get worse rather than better. A few mutations bring an improvement: possibly the offspring will be stronger, faster, smarter, on any of a million other ways to “improve.” This is where natural selection comes in; the environment weeds out faulty genes and their owners, and — on average — good genes enable their owners to have more offspring. Evolution happens.
In the 1990’s, after his talk at a meeting I asked a geologist: “If huge numbers of incoming cosmic rays during these zero-point magnetic field events cause mutation rates to explode, wouldn’t a lot of animals die — from cancer, say — and greater numbers than usual of beneficial genes appear? Perhaps this has something to do with Gould and Eldredge’s theory of punctuated equilibrium? Nothing much changes for hundreds of thousands of years, then a magnetic pole reversal occurs, and suddenly new species appear and others disappear.”
“Interesting idea,” he said. “Possibly true, but I don’t know how anyone is ever going to be able to test it, or prove it, or disprove it.”
Time moves on, discoveries are made. Apparently we’re getting closer to testing and proving this idea.
ScienceNews.org | Carolyn Gramling | 18 February 2021
A flip-flop of Earth’s magnetic poles between 42,000 and 41,000 years ago briefly but dramatically shrank the magnetic field’s strength — and may have triggered a cascade of environmental crises on Earth, a new study suggests.
With the help of new, precise carbon dating obtained from ancient tree fossils, the researchers correlated shifts in climate patterns, large mammal extinctions and even changes in human behavior just before and during the Laschamps excursion, a brief reversal of the magnetic poles that lasted less than a thousand years. It’s the first study to directly link a magnetic pole reversal to large-scale environmental changes, the team reports in the Feb. 19 Science.
During a reversal, Earth’s protective magnetic field, which shields the planet from a barrage of charged particles streaming from the sun, can lose strength (SN: 1/28/19). So some researchers have suggested that these flip-flops may be linked to extinction events (SN: 11/19/20).
Kauri trees (one shown) have grown in New Zealand for thousands of years. By analyzing tree rings of preserved trees in the Ngawha swampland, scientists identified evidence to suggest a magnetic pole flip around 41,000 years ago.Mark Meredith/Moment/Getty Images
