Announcing….A story set in Madagascar!

I’ve written a children’s book about Mouse Lemurs and baobab trees, illustrated with some amazing AI art created by daughter Alison (the person who got me started on this blog more than 12 years ago). 

Back and front covers of the book. Click on the image to enlarge it and read the brief description of the story.

The book was inspired by my recent visit to Madagascar, specifically by the incredible wildlife and plants we saw and the stories we heard about them. The visit there was enlightening, but at the same time depressing, because we were made aware of how precarious survival of native species is in the face of escalating human development. And so another reason for writing this story for kids was to highlight the unique biological relationships of plants and animals in Madagascar and raise awareness of their fragile existence. 

A couple of examples of the artwork and story line:

Luna’s Quest was published on Amazon Kindle and is now available for purchase.

As mentioned in the book description on Amazon, proceeds from sale of the book are to be donated to conservation efforts in Madagascar, specifically (at this time) to the Lemur Center at Duke University. I think the story content is appropriate for ages 3-12; try it out on your kids, grandkids, nieces, nephews, etc.

Several pages at the end of the story are devoted to some description of the natural history of the main characters of the story and discussion questions for Young Readers.

Remembering the year that was…

This year was an amazing time of one adventure after another…as we made up for the Covid isolation period and two years of postponed trips. So many beautiful places, beautiful animals, beautiful landscapes, and amazing people that we met. Here’s a snapshot of the year in review.

(Note: if you’re interested in seeing more and perhaps better photos of any of the activities mentioned below, go to the main page of the blog: https://bybio.wordpress.com and there should be a pull-down menu for the Archives with months and years of the blog listed near the top right of the main page. Just click on the month of interest, and scroll down through the days to see more of what I have summarized here. IPhone and iPad users may have to scroll to the bottom of the main page to see the dialog boxes with the months listed.)

The highlight of a trip to northern Minnesota to photograph the winter avian residents there was watching a very cooperative Great Gray Owl get four mice (from under the snow) in just four attempts — 100% success!

We took the long-awaited, much postponed cruise down the west coast of Mexico and Central America through the Panama Canal, ending up in Florida. Birding from the ship turned out to be a big plus.

Photography buddy Debby invited us to stay at Hilton Head, SC for a week to marvel at the huge numbers of shorebirds and others that overwinter in this milder mid-Atlantic climate.

As a prelude to our birding adventure in Spain in April-May, we took ourselves sight-seeing in Portugal, with a few days birding and exploring Lisbon, a train ride to Porto, and a few days there before ending the prelude in Madrid (a much more beautiful city than I remembered).

Birding extravaganza in the plains, forests, shore, swamps, and even in old cities in the Extremadura region and Donana national park in southern Spain with Ruth Miller and Alan Davies — birders extraordinaire

The annual family hike in our favorite haunts of the Desolation Wilderness of the Sierra Nevada mountains of California took place early this year (to avoid a repeat of the disastrous smoke and fire threat we faced last year on the hike in August). We were rewarded with 100% warm, sunny days and no bugs!

Some of the family rode an airplane home from the Sierra hike, but two grandsons were kind enough to keep their grandparents company on a road trip from California through Nevada, Wyoming, Utah, Colorado, Nebraska, and South Dakota on the way back to Minnesota. Sights were seen and adventures were had along the way.

Although tamer than the previous months of travel, the backyard did not disappoint in bringing wildlife and beautiful scenes for photography. I realize in writing this now that I forgot to include the visit from the kit fox and its mama in August.

We always make at least one trip out to the central Minnesota prairie during the summer, and this year we found ground squirrels and monarch butterflies at Fort Riley state park. The tom turkeys visited the front and the back yards often, but without their girl friends.

A trip to eastern Europe (the Balkan countries) was a premier highlight of the year. It was definitely a learning and discovery adventure since we knew nothing about this part of the world. Croatia, Bosnia-Herzegovina, Montenegro, and Slovenia — all beautiful, all very interesting though with tragic stories from inhabitants, and all easy to travel around with lots of friendly folks that spoke English.

As always, the fall color spectacle in the Twin Cities did not disappoint. The colors remained vivid for a long time, even into November before the trees finally gave up with the snowfall that began late this year on Nov. 12.

The forest outside became a fairy land of white-encrusted branches after the first major dump of very wet snow in December. Inside the tree was decorated with lights, mementos, and presents. Happy holidays!!

the Monarch magnet

Meadow Blazing Star attracts butterflies like catnip attracts cats. They stay on the plants for hours, flying around the flowers, dipping into them, chasing each other, and just generally hanging out by the vibrant purple blooms. I highly recommend it for your garden.

Monarch butterflies are especially fond of this tall (about 5 feet) spike of purple-pink blooms that are so highly visible and last such a long time in the garden.

The individual flowers of meadow blazing star are densely packed on a very long stem. I don’t know if this species of Liatris has more nectar than other blazing star species, but there are so many flowers and such a long blooming time, it provides a stable nectar resource for all sorts of insects.

An occasional bumblebee might try to land on these flowers, but the Monarchs usually chase them off.

We found an isolated stand of meadow blazing star in a prairie area at Fort Ridgely State Park on the Minnesota River near New Ulm, and this stand too, was a magnet for the Monarch butterflies with more than a dozen of them flying around the flowers continuously.

These Monarchs are most likely the final generation of the summer — the individuals that will fatten up on rich nectar resources from blazing star and other flowers and then begin a 2-3,000 mile journey to their overwintering sites in montane forest areas of central Mexico. Flying about 50-100 miles a day, it will take them more than two months to complete their migration. They depend on finding more nectar resources as they travel south through the American midwest, then south to Texas, and on through northern Mexico — an amazing feat of stamina and navigation in order to return to their overwintering site.

Chiracahua beauty

The Chiracahua mountains of southeastern Arizona offer a multitude of scenic vistas, as well as a bounty of incredible wildlife to see.

There are a lot of canyons formed by rivers running down from the peaks of these 6-8,000 foot mountains. This is the entrance to Cave Creek canyon, one of our favorite places to stay and explore.

Rock formations and cliff faces line the sides of the canyons. You can easily see the altitudinal changes in vegetation as you ascend to mountain peaks.

The Chiricahua Mountains rise more than 6,000 feet above the desert floor that surrounds them, making them “islands in a sea of desert”. A variety of life zones occur along a gradient from hot, dry desert to cool pine forest at peak elevation, which means these montane islands are a hot spot of biodiversity. 

We found a giant meadow of blue flag iris at Rustler Park, up at 8200 feet. Lots of butterflies and Anna hummingbirds flitted around these flowers sipping their nectar.

I think this might be the Western Pygmy Blue butterfly on the iris. These are one of the smallest of the southwestern butterflies, only 1/2 to 3/4 inch across. They can be found right out on the desert floor, as well as in the canyons and mountains. The caterpillars manage to survive on a diet of desert saltbush in the most arid desert conditions — amazing!

On the other end of the size spectrum were these gigantic Two-tailed Swallowtail butterflies, with a wingspan ranging from 3-6 inches, making it the largest Swallowtail in western North America. This species is the state butterfly of Arizona.

Adults only live 7-14 days and feed only on nectar, but the caterpillars prefer chokecherry or poplar leaves, and are a striking orange color with a big eyespot on their rear end to deter predators.

The Swallowtail I was photographing suddenly took off — and here’s the reason why. An aggressive little male Anna’s hummingbird, about the same size as the swallowtail just buzzed in for a drink of iris nectar.

it’s feeling fallish

We spent a beautiful morning walking along the St. Croix river at Afton State Park recently, and I noticed that it seems more like fall weather now, and a lot less like summer. What a difference a couple of weeks makes in the climate here.

The beach along the Minnesota side of the St. Croix river is deserted…just the way I like it. There are a few warblers around, geese are flocking up in preparation for migration, and the last of the summer wildflowers are holding onto their blooms, just a little longer.

A somewhat bedraggled Great Spangled Fritillary was foraging on the Sneezeweed flowers — just about the only wildflowers left along this shoreline of the river. This is one of the largest, and longest lived butterflies here in MN. It mates in June but doesn’t lay eggs until August and September, somewhere near a patch of violets, on which its larvae will feed in the spring.

Cedar Waxwings were acting like flycatchers as they perched and then sallied out to catch whatever insects were flying by their perch.

And the ever-present and numerous Canada Geese are now gathering in large flocks to prepare for migration. Here they come downriver right at us…

They fly so closely together you would think their wings would get in the way of each other. In fact, so close that two birds on the right side of the photo look like one bird with four wings!

Nothing symbolizes fall in Minnesota like these flights of Canada Geese.

Fall may be my favorite season, even though it leads into my most dreaded season of bitter winter. But I love the fall weather and color as the landscape begins to glow.

Blooms in the backyard

In the Minnesota backyard, some of the summer blooms are in their full glory, particularly the purple coneflower. Butterflies and bees are drawn to these flowers…

A Great Spangled Fritillary stopped by…

And examined each of the disk flowers in the flower head intensively.

I caught the approach of one of the honeybees buzzing the coneflowers.

And was able to zero in on the bee when it landed.

Even the Goldfinches were checking on the flower heads, I suppose to see if they had made any seed yet. But these flowers have just opened up in the last few days.

A hike in a Sierra meadow

There are lots of trails to explore in the Lake Tahoe basin, and we took the grandkids on a “walk” from their cabin on Fallen Leaf lake all the way to a swimming beach on Lake Tahoe — an almost 7 mile hike. Naturally, there were a number of stops to rest and swim at places along the way, and there was a promise of ice cream at the end of the hike, and that’s all it took to get the kids there.

The water of Fallen Leaf lake is as clear as that of Lake Tahoe, but right now the water near shore is more of a greenish color due to all the pine pollen accumulating there. If the glaciers that created it had continued to carve their path from the Glen Alpine valley, this lake would simply be a bay of Lake Tahoe.

The trail along the east side of the lake wanders through countless meadows and stands of Jeffrey pine (the one that has a scent of vanilla wafting from the cracks in its bark). The tall meadow lupine was in full bloom.

Another blue-purple flower that I thought was forget-me-not turned out to be Pacific Hound’s Tongue, so named for the shape of its basal leaves that resemble a dog’s tongue. The flowers were loaded with small Two-banded Checkered Skipper butterflies feasting on nectar.

Juncos are already far along in their nesting cycle, feeding their rapidly growing chicks.

A Red-breasted Sapsucker checked us out as we walked under him on our trek by the salmon run on Taylor Creek. I wonder if this is the same bird we saw here in April at this spot?

White-headed Woodpeckers are somewhat common in the pine forest here in the Tahoe basin. This female was feeding chicks in the nest (on her left) and not at all shy about us walking near her.

Flowers of the desert

Although we have been a little early in some places and a little late in others, we still have seen some of the spring wildflower show as we travel.

One of the most exotic flowers we saw were on this claret cup cactus, actually an endangered species found only at the intersection of Arizona, New Mexico, and Mexico — which is exactly where we were when we saw it. The plant puts out brilliant scarlet flowers on cylindrical stems that mound together into a cactus clump.

The color of the flowers suggests it might be pollinated by hummingbirds, although the shape of the flower is wrong. However, the “flower” is actually the outer sepals and petals combined, and the nectar reward for the hummingbird pollinators is in the central chamber surrounded by hundreds of thready stamens.

Cylindrical flowers of the Ocotillo are the more typical hummingbird floral type, but a number of other birds enjoy these flowers for their nectar, as well as the insects they attract.

Why bother probing into the flower for nectar when you can just rip the flower off the stem and eat the whole thing, as this male Pyrrhuloxia is doing?

Looking for insects on unopened Ocotillo buds? A male Gila Woodpecker might enjoy both a nectar and an insect reward from these flowers.

A female Rufous Hummingbird foraged on a bunch of Penstemon flowers in the early morning at Cave Creek ranch in Portal Arizona.

A Clear-wing Moth and Pygmy Blue butterfly foraged on the bush lupine right outside our room at Cave Creek ranch in Portal Arizona. This plant had so many flowers and apparently so much nectar, it was constantly moving with the all the butterflies and bees swarming on it.

The Southern California deserts didn’t receive enough rain this year to produce much of a wildflower show, but the Desert Agave still bloomed here, along with many Ocotillo plants, giving this desert in Anza Borrego State Park some color. The Agave plants only send up one flower spike in their lifetime, as tall as the plant’s energy resources will allow, to attract bats to pollinate them.

look-alikes (and not)

The Grass Lake slough at Snail Lake regional park is teeming with butterflies, especially Monarchs, which may be congregating here for their southward migration.  The Monarchs especially seem to like the meadow blazing star and don’t even mind sharing it with a lot of other butterflies, bees, etc.

The number of flowers present on meadow blazing star is one reason that butterflies congregate on it. The fact that it provides a lot of nectar at a time (late August) when butterflies are migrating is another.

Plenty of nectar to go around for Painted Ladies (also migrating by the thousands in late summer), Monarchs, bumblebees, honeybees, and a few stray beetles.  The orange, black, and white pattern of the Painted Lady is similar to that of Monarchs, but they are not mimics and the two are easily distinguished from one another.

But one of the many Monarch butterflies I photographed wasn’t a Monarch, but a Monarch mimic, the Viceroy, and these two unrelated species ARE difficult to tell apart.  Can you spot the difference(s)?

Both species exhibit the bold orange and black pattern on the wings as well as the pattern of white dots on the black head and thorax of the insect. 

The biggest difference in coloration of the two species is the bold black horizontal (sort of) stripe on the hind wing of the Viceroy, seen from above or below.  The thick black lines on the hind wing of the Viceroy are similar to those of a female Monarch but are much bolder than the male Monarch’s, which also has a distinctive dot on each hind wing.  In addition, Viceroy butterflies are smaller in size, only about 2/3 the size of a Monarch.

But where Monarch caterpillars grow up eating milkweeds containing poisonous cardiac glycosides which they sequester in their bodies (and wings), Viceroy caterpillars eat willow, poplar, and cottonwoods — not at all poisonous. Bird predators find Monarch butterflies extremely distasteful and will regurgitate or spit them out. Viceroy butterflies that most closely resemble their poisonous cousins in coloration are better protected from predation, and thus, the mimics survive to reproduce.

And then there are these two, apparently dissimilar butterflies, flitting around the same plants, often displacing each other from the same flowers.

The Eastern Tiger Swallowtail comes in two colors: yellow and black, and black.

Not at all look-alikes, in fact, color-wise, they couldn’t look more different, except for the pattern of white dots around the margin of the wings and the distinctive iridescent blue splashes of color on the back end of the hind wings.  So, what’s going on here?

Male Eastern Tiger Swallowtail butterflies are almost always yellow with black stripes.  Females on the other hand vary between yellow morphs and black morphs.  And, the black morph is more commonly found in the southeastern U.S. where a similar-colored, poisonous and unpalatable Pipevine Swallowtail butterfly occurs.  These are the “look-alike” models for the Tiger Swallowtail (and other Swallowtail butterfly species) to copy.  Interestingly, the proportion of female black morphs of the Tiger Swallowtail is higher in southern populations because of genetic (sex-linked) process that makes black morph females produce mostly black morph females, and yellow females produce mostly yellow females!

Bottom line:  you have to look closely when identifying a butterfly, because it might be a mimic!

it’s not always a perfect fit

While waiting for the hummingbirds to show up to have their photos taken last week, I got plenty of time to watch some insect pollinators in action.  Some plants are obviously not fussy about what or how many pollinators they attract, so they put out a vast array of flowers — like a buffet table.

Black-eyed Susans and Purple Coneflower put their pollen and nectar up for grabs on the tiny disc flowers at the center of the flower. All comers are welcome to partake here — in this case, a Tiger Swallowtail was dipping its long proboscis carefully into each of the tiny openings of the disc flowers.

But some plants are fussier about which pollinator they cater to and which they can physically exclude.  It was amusing to watch several different bee species work the plants with tubular flowers, especially the ones with deep necks, like Salvia and Bee Balm.

A slender honeybee fits just perfectly into the deep corolla of a Salvia plant, as it crawls down to the base where the nectar is located.  Bumblebees would not fit here.

Both honeybees (above) and common eastern bumblebees (in this photo) “flock” to the Hyssop plants in great numbers.  But you notice that the while honeybee’s head fills the flower opening, the bumblebee’s head is too big, and it must rely on a long tongue to reach the nectar at the base.

Sometimes smaller is better, as far as pollination of the flower is concerned, because the smaller honeybee does a better job of contacting the flower’s reproductive parts and transferring pollen from one flower to the next.

Lobelia flowers were a perfect fit for the smaller worker bumblebees, but that didn’t keep larger-bodied bumblebees from trying to get its nectar.

Look what happens when this medium-sized bumblebee tries to get into the Lobelia flower.

This bumblebee is too big to fit into the flower opening, while another, smaller worker bumblebee, (below) crawls right in.  And notice how nicely that smaller bee contacts the protruding (white) stigma (the female reproductive part) of the flower as it enters and exits.  No doubt this bee will transfer pollen effectively.

This bee was able to work itself all the way into the flower, so that just the back legs were dangling outside.

Meanwhile, tiny little forget-me-not flowers, with their miniscule central opening, require the services of small bees with slender tongues to reach the chamber with the nectar.  Sweat bees are just the right size, and I found two different species hovering and probing the flowers.

That’s a pretty tiny opening to access this flower for its nectar supply.

Green sweat bees are common in the garden — I hadn’t noticed the black variety before today.  The green one looks well dusted with pollen.  Both species have sleek, almost hairless abdomens, unlike bumblebees and honeybees, but have lots of short hairs on their heads and abdomens, great places to collect pollen as they search flowers for nectar.
