Today, May 16th, just so happens to be National Love a Tree Day! It’s the official day to celebrate all of life’s joys brought to us by the trees we share this planet with. Whether you love reading in the shade or taking a bite out of a fresh fruit pie, National Love a Tree Day encourages y’all to get outside and enjoy a tree.
A Changing Landscape
We all know many tree species live many many years; some live to be several thousand years old. According to the U.S. Forest Service, about 766 million acres of forest land exists in the United States today, a number that’s held steady since 2012. But the nature of our forests has changed over the last 400 years, due to changes in management practices and demand. Population growth, rural and urban development, along with a variety of land uses (like conversion of forests to agriculture use) resulted in a steady decline of forested acres between 1630 and 1910; a decline from 1,023 million acres to 753 million acres or 46% to 34% of the total land area in the U.S. Since that time until the present, where people choose to live and how the land is used has been constantly changing. While some urban forests increase, other areas see a decline. Tree planting programs improve landscapes but human activities and population growth continue to impact these ecosystems.
We All Benefit from Trees
Trees provide more than just beautiful landscapes and a shady canopy on a sunny day. They play a significant role in reducing erosion and moderating the climate as well as give us oxygen. Large quantities of carbon are stored in their tissues as trees remove carbon dioxide from the atmosphere. They provide habitat and structure for strong ecosystems.
How to Observe National Love a Tree Day
This is a good day to plant a new tree native to your area, or spend some time enjoying the beauty of the trees, Take time to learn how to care for the trees you have, too, whether you live in the mountains or the desert. Write down all the reasons trees are important to you. If you have a favorite tree, or a tree you’re not familiar with, begin a little research project about that (or those) species, and journal about your findings.
Of all the hummingbirds migrating through central New Mexico, the male Rufous ‘hummer’ (Selasphorusrufous) is the most spectacular. Showing up when our hot Summer temps begin to soar, he has two things on his mind ……. #1. find the best patch of nectar-rich tubular flowers, and #2. keeping that patch all to himself to refuel before completing his 4,000 mile migration from southern Mexico to southern Alaska. Upon arriving from Mexico, the flashy 2-1/2” long Rufous, garbed in a feathery cloak of flame colored oranges and reds, quickly lays claim to an area of sweetly blooming flowers that may include penstemon, columbine, scarlet gilia, Indian paintbrush, mint, lily, fireweed, larkspur, currant, and heath. Determined to defend his patch against all invaders, he performs a quick flower flyover. If satisfied the coast is clear (for now), he takes up a strategic observational post by perching on a nearby tree branch to watch for rival hummers.
Ever alert and constantly in motion, his perch gives him a great vantage point to scan the area by looking right and left/up and down, all the while making quiet chittering and chipping noises. If another hummer, and especially a male Rufous dares to enter his territory and sip from his flowers, oh no! Becoming highly agitated, the perched bird spreads his tail while flashing his colorful gorget (throat feathers) seconds before dive bombing his competitor, loudly screaming his alert call while attempting scare off the thief. If this tactic doesn’t work, i.e. the rival is determined to hold his piece of air space, a duel is declared.
Rufous hummers are well known for their aerial acrobatics. Perhaps you’ve witnessed their display, which likely put you in awe of this little powerhouse. If not, what you’ve missed is their incredible speed of initial attack, their precision, the cacophony of noise coming from such a tiny blur of a bird, the maneuverability of numerous aerial loop-de-loops and J-pattern sky displays allowing them to dive repeatedly at their foe, and their tireless determination in defending their rights to their flowers. It’s a spectacle you have to see to believe!
The Rufous will attack not only males and females of their species, but hummingbirds of all species, and even large insects, all with the audacity to steal precious nectar from his prized flowers.
And never, ever sit near or below a hummingbird feeder when there’s a Rufous in the neighborhood. I learned the hard way after being attacked over and over again by a surprisingly intimidating Rufous hummer. Despite being thankful I chose to wear a hat that afternoon, a large dose of common sense had me backing away from his feeder for fear he might have a stroke before drawing blood. My heart still races when recalling this thrilling yet scary encounter.
While reading about the Rufous, I learned that all ages and both sexes of this species are aggressive, even during their brief 1-2 week migration stopovers. This is certainly very good information to know about, having only witnessed males launch themselves at intruders, myself included!
Can’t wait for Rufous migration season!
Have you learned something new about this wildly fascinating and fiery hot hummer of southern Mexico, the Western US, Canada and southern Alaska? If you have a Rufous or any hummingbird story to share, please do! Oh, I also hope you’ve enjoyed my colored pencil artwork of a male Rufous about to sip nectar from a freshly blooming penstemon.

On a warm Spring morning, wandering around a grove of American Sycamore, I became curious about these magnificent trees: where in the US are they native; why are some leaves larger than the palm of my hand and some half the size; what about those odd pingpong sized seedballs lying on the ground everywhere you look ….. why don’t they roll away in search of an ideal spot to pop open so the seeds can germinate …… when the seedballs are kicked, stepped on or crushed beneath a car tire, do the 1,000’s of seeds inside blow away to sprout ….. are the seeds (all or some of them) even viable ….. do the seedballs make a good ink or dye or maybe they’re edible or even medicinal……. what, if any wildlife species eat the seedballs or seeds; and ooooohhhhhhh, sycamore bark! Why does this tree’s bark flaunt a pastel palette of greens, yellows and pinks. These and many more questions came to mind that it seemed about time the American Sycamore became a subject for my nature journal, until ……………..
There! In the tree above my head, I spotted a most curious thing. Parting a few of that sycamore’s beautiful Spring green palmate-shaped leaves was a bundle of dead brown and beige leafy bits and sticks all haphazardly glued together. Wishing to get a closer look at that elongated ornament shaped “thing,” I found it was securely suspended from a branch. Trying to puzzle out this fascinating mystery while searching for my pen knife, a stiff breeze blew through the tree. It was then a I noticed hundreds of those 2-3” long bundles all over the tree; from the base to its crown!
Curiosity is the Essence of Nature Journaling
What continues to draw me to nature and nature journaling after so many years are the surprises in the familiar and in the unknown. I know well enough that new encounters in nature are infinite; you just have to open your eyes and look. Having learned by carefully observing what appears to be familiar, often leads to new discoveries. That’s when my curiosity kicks into high gear ….. when it’s time to engage in some serious poking around to figure something out; to learn what the “thing” is.
Curiosity, for me, is the very heart and soul of nature journaling. The ‘art’ of curiosity even precedes skill in observation. It’s what drives me out the door in the morning and fuels my exploration. Curiosity fills the mind with countless questions if for no other reason but to develop a deeper understanding of the natural world.
But I “wax philosophical.” Needless to say, my curious discovery on that warm and breezy Spring morning prompted an abrupt change of mind for my next blog post (this post). Anxious to learn about the “thing” suspended from a tree branch, probably minding its own business, I proceeded to cut it down (along with two more) and popped them in a bag along with a few sycamore leaves and seedballs.
Later that same day …….
Upon completing my journal sketches of sycamore leaves and seedballs, and posting a few photos to iNaturalist for an initial ID, it was time to take a closer look at my discovery. Reaching into the bag for one of the “things” (wiping my hand free of spider webbing?), I placed it on my examination table surrounded by several hand lenses, a larger magnifying glass, a penknife, and 2 pairs of tweezers. Before beginning the dissection, I noticed about a dozen black pepper-sized bits moving about the “thing.” Thinking tiny spiders had come from the bag, I didn’t give them a second thought (should’ve been curious!).
This bagworm bag was the subject of my dissection. Notice the pepper-sized black dots next to the bag ….. those are wiggling 1st instar larva.

A Bagworm Moth!
How cool is that!?!

Dissection resumes ……
After finding out the “thing” I’ve been pondering over is the Bag of a bagwormmoth, I learned the Bag was built during last Spring, Summer and Fall by either a male or female bagworm moth. If a male, the Bag would be empty; if a female, the Bag would contain her remains …. she would’ve died last fall after a male fertilized 500-1,000+ eggs she overwintered inside her body until Spring when newly-hatched larvae would emerge from the bottom of the Bag and begin the species’ life cycle all over again.
The Bag, that took about 10 minutes and all my dissection tools to open, contained the black and mushy remains of a female and 100’s of wiggling/dancing larvae! They were on the move; escaping from the now wide open Bag, and quickly covering my examination table like a pepper grinder out of control.
And my effort to open the Bag? This made sense after reading about the high tensile strength of the silk they produce. These thin strands of silk, 10x stronger than that produced by silkworms, is used in abundance to construct their Bags.
The coolest thing ever! Notice the either late 2nd or early 3rd instar larva, no longer naked, but swaddled in very chewed up leafy bits glued together with strong silk. This dude was hiking up a sycamore branch, continually chewing, wiggling, and gluing.
After disposing of all the naked 1st instar larvae waggling and dancing across my examination table, I placed the dissected Bag, the two whole Bags, and collected leaf material into a clear plastic ziplock to observe what would happen. Over 10 days, the number of larvae multiplied and the naked 1st instar caterpillars grew in size (at least to 2nd instar) while building their individual Bags from tiny bits of leaf litter! Their wiggling dance seemed to be the way their silk strands wrapped and secured leafy bits around their bodies. It’s been fun to watch all the activity.
Have you ever encountered one or more of the 1,350+ species of bagworm moths? What materials were their Bags made from? Please share your experience with these fascinating members of the butterfly/moth family of insects.
