Readers’ wildlife videos

Robert Lang, reader, physicist, and origami master, sent us some lovely videos he took from his California studio. These were sent on May 14, and Robert’s captions are indented.

These all come from a camera I have set up outside my studio window, so it’s capturing pretty much the view I have during the day at work (the animal visits are great, but my productivity has taken a nosedive). The critter cam has an IR feature, which lets me also get visitors who only show up at night. That’s when I’ve had most of my Gray Fox (Urocyon cinereoargenteus) visitors. (They are honorary cats, I hear.)

The meadow (mostly bare this spring, due to the poor rains this past winter) is prime habitat for California Ground Squirrels (Otospermophilus beecheyi). Sometimes, though, the Western Gray Squirrels (Sciurus griseus anthonyi) come out of the trees, like this one.
I get visitations from two types of rabbits: Brush Rabbits (Sylvilagus bachmani) and Desert (or Audobon’s) Cottontails (Sylvilagus audubonii). These are the latter. They’re distinguishable by (among other things) the black rim on their ears (which the Brush Rabbits lack; also the Brush Rabbits stick close to the brush line at the back of the lot, so I rarely get videos as they’re too far away.) These are being a bit frisky with each other.
I’ve seen way more rabbits this year than in previous years (and not many bobcat or coyotes). There’s probably some sort of relationship there.
We get lots of California Mule Deer (Odocoileus hemionus californicus). This one is ready for her close-up, Mr. DeMille.
And the grand finale, from this morning: an American Black Bear (Ursus americanus). Although California extirpated its grizzlies from everywhere but the state flag back in the 1920s, the Black Bear continues to spread throughout the state. They regularly come out of the mountains to visit the adjacent neighborhoods, and in recent months, a mother and two cubs have become downright famous in Altadena via postings from neighborhood security cameras. Despite the name “black bear,” their color is highly variable; the ones around here range from rich brown (like this one) to nearly blond.

Our friend Tara Tanaka (Vimeo site here, Flickr site here) lives on a plot of land in Florida that includes wetlands, and she often films the residents. Today she’s sent us another of her videos, this time of red-bellied woodpeckers (Melanerpes carolinus) raising their young. There’s a scary snake, but it doesn’t get any of the birds.

Tara’s notes are indented, and be sure to enlarge the video when you watch it.

On Feb. 8th we observed this pair mating and their newly excavated cavity in a dead maple tree on the edge of the swamp.  The cavity is very well hidden behind dead branches and Spanish moss, and they even built it right under an overhang of separating bark that keeps the rain out.  I recognize this male’s distinctive face and have been photographing him for years.  I’ve been watching this female for at least two years – she drinks from the hummingbird feeder right in front on my PC.

The first clip was recorded on Mar. 23rd, and at the time we didn’t know if they had hatchlings yet or not, but I’ve since learned that incubation only lasts about 12 days for this species.  From the detailed information I was able to find on birdsoftheworld.org, these nestlings are approx. 15-20 days old, and will fledge at around 24-27 days.

On Apr. 26th my husband heard and saw the parents very upset – vocalizing and flying back and forth from the nest tree to the large water oak a few feet away.  After much searching, we found a large gray rat snake in the water oak trying to find a path over to the dead tree where the nestlings sat helpless in their cavity.  As soon as we saw the cavity in the maple tree in February we wrapped the bottom of it with wildlife netting to prevent any rat snakes from reaching the nest.  We have already removed one snake that became entangled in the netting and relocated him far away, so it was not possible for the snake to get up the maple, but his determination had him trying to reach the nestlings from another tree.

I always keep water in a small vase mounted on a tree right in front of my office window that I put up just for the woodpeckers, but other birds use it too. Woodpeckers drink from knot holes in trees, but they have become used to the fresh water and drink from it multiple times a day.  During last year’s nest season we had a severe drought, and I think that the constant (the female is drinking now 😊) supply of fresh water, peanut halves and Bark Butter allowed them to raise three healthy young that they brought to my feeding station as soon as they fledged.  In one video this year I even saw the female feeding Bark Butter to a nestling, however both parents typically arrive with beakfulls of grubs and other insects.

I’m sure I’m seeing at least two nestlings – there may be three.  I’ll be holding my breath until they make it out safely!

When it rains it pours: Tara Tanaka has graced us with another video, this time with the mating display of a male great egret (Ardea alba), the formation of a pair bond, and the beginnings of a nest. It is so beautiful that it made me tear up. And the male bringing sticks for the nest is fantastic. Be sure to watch this on the big screen.

Her video notes:

This is the closest Great Egret nest site in our backyard wildlife sanctuary – approximately 250’ away. There hasn’t been a nest here is a couple of years due to low water, but the afternoon before last I saw a male displaying on a branch, and the next morning he had already attracted a mate. He repeatedly brought branches from across the pond, and with sometimes questionable hand-offs she skillfully wove the sticks into their growing nest.

We are really running low on readers’ wildlife photos, so if you have some good ones, now’s the time to send them in.

Today we have two videos by the late photographer and naturalist Andreas Kay from Ecuador.  The first is a caterpillar presumably mimicking a feather—a form of mimicry new to me.  Andreas’s YouTube notes:

This Caterpillar filmed near Mindo in Ecuador looks like a feather which presumably gives it an advantage in the struggle for survival since predators such as birds will not perceive it as food. There are more than 3500 species of butterflies and some 10000 of moths in Ecuador and their larvae have evolved different strategies to escape predators. Some hide in the vegatation due to camouflage coloration, others resemble a stick or moss or mimick bird droppings.

Bagworms build cases out of silk and materials such as leafs, wood and soil as camouflage, such as this Pagoda bagworm: https://rumble.com/v48got. Other caterpillars on the contrary are highly colorful (aposematic coloration) to warn potential predators that they are unpaltable or even toxic or have venemous spines. Some caterpillars expose fake eyes to deter predators, such as this snake mimic caterpillar from Ecuador: https://rumble.com/v311ab

But this is an exceptional case of a caterpillar disguised as a feather. It even makes steps back as it moves as if it was agitated by the wind.

And some slow-motion photography of a beetle. The carapace could be regarded as vestigial wings, as it evolved from wings in an ancestor:

Tortoise beetles, Cassidinae own their name to the carapace under which they can find shelter like a tortoise, with the difference that their carapace can open for flight. This species with the scientific name Stolas coalita is from the Amazon rainforest of Ecuador.

Today we have two—count them, two—videos.

I had forgotten about the backlog of wonderful videos by the late Ecuadorian naturalist and photographer Andreas Kay, but he posted quite a few before he died at only 56. I’ll parcel them out over the coming months.  Here are his notes on a remarkable caterpillar that almost certainly deters predators by mimicking a snake. Note that, relative to the body, the “snake head” is upside down so, when presented by a clinging caterpillar, it looks like a right-side-up head.

Snake-mimic caterpillar, Hemeroplanes triptolemus, Sphingidae from the Amazon rainforest near Puyo, Ecuador. When disturbed this larva of a sphinx moth expands and exposes the underside of the first body segments, mimicking a snake head with black eyes and even light reflections. Sometimes it also strikes like a snake to deter predators such as lizards or birds. Photos here.

And Rick Longworth made this video, complete with music, of a den of foxes (mom plus kits). The play behavior of the kits is adorable. Rick’s notes:

Red fox (Vulpes vulpes). At the end of May, I noticed a group of about 5 or 6 young foxes across the Snake River at a distance of about one third of a mile from my back deck. The mother had dug a den in an earthen mound at the end of a utility road between two farms. At maximum magnification, the uneven heating of the atmosphere made the image quite unsteady.

We have two contributors today. First, Art Williams sent some photos and videos, which include a fawn. Remember, if you see a fawn by itself, especially a very young one, leave it alone, as it’s almost certain that it was been left to shelter place while Mom went off foraging. Only call for help if it stays in place and mom doesn’t return for a day or so. Art’s captions are indented.

Here are some photos and a video of the suburban wildlife around Loveland, Ohio, just outside of Cincinnati. The raptor is a juvenile red-tailed hawk, I think. He or she and mate have been very active, screeching their presence every morning, likely having a brood somewhere close by.

My wife noticed the fawn sunning itself in the yard and couldn’t have been more than a few hours old. Its mom had left to forage and he instinctively knew to head for the dappled shadowy cover of a nearby Hemlock tree. The link to the video shows just how wobbly the little guy is. It’s a little shaky and narrated by my over-concerned wife who fears the baby has been left by its mom. After several hours we were worried that it actually had been abandoned, but Mom came back eventually and the two scampered off into the woods.

JAC: Fawns are so beautiful! They’re the ducklings of mammals.

Art also sent a video he made:

And an astronomy photo by Tim Anderson in Australia:

This image shows NGC4956, a large barred spiral galaxy in the Centaurus constellation. It also shows a number of other, more distant galaxies dotted around the field of view. The galaxy was first observed by James Dunlap from Parramatta in NSW during 1826.

Today we have a video of an interspecific brawl sent by Swiss biologist Jacques Hausser and taken by his daughter in law in the town of Bassins (also Switzerland) last Friday. With permission, I put the video on YouTube so I could embed it.

Jacques’s title and notes are indented below. There are also three bonus photos:

Interspecific fighting for a nesting hole

This afternoon, Deny, my daughter-in-law, heard a great commotion, followed by a thump, and saw two birds fighting on the ground. She videotaped part of the scene, then brought me the two birds still clutching to each other. Unable to get them apart (the sharp claws of the swift were firmly hooked in the starling’s flesh) I had to bring them to a rehab center.

Why this fight? The neighbor’s house  was partly renovated this winter, and, quite typically, several nesting opportunities disappeared in the process, including probably the one of this frustrated swift coming back from Africa, who tried to expel the starling from its  nest – I found some eggs broken on the soil, too. I had planned to built swift nesting boxes, but with the Covid-19, my plans remained at the paper stage…

The cast of characters (be sure to put the sound up):

Starling: Starling, Sturnus vulgaris, and Common swift, Apus apus.
Interested onlooker and would-be actor: Domino, my cat [Felis catus].
Vocals: mostly carrion crow, Corvus corone, very interested too.

I asked Jacques if the birds would be okay, and apparently the swift was released swiftly (that’s a “Tom Swifty“, making it a double pun), but the starling, with a wound in the chest, will require more days of care, though she too will pull through (see below):

it was something not observed every day. The video was taken by my daughter-in-law Denielle Hausser. According to the staff in the rehab, the starling will be OK after some more days of care.
More information from Jacques:
Looking at the picture below from Professor David Norman of the Merseyside ringing group (reproduced with permission), you can understand the suffering of the starling! Although “Apus” means footless, swift have rather special “pamprodactyl” feet, with the four fingers usually kept more or less parallel in the front direction – to hang on vertical walls – but they can oppose fingers 1-2 to fingers 3-4 to grasp something – including perhaps each other in their aerial mating. Remember that swifts can stay in the air up to 9 months, loving, hunting, sleeping, and drinking on the wing. They land only for breeding, or when they are caught in a bad or cold weather.

Look at those swift talons!
I have a picture of the male (?) starling from the same pair.
The swifts are hard to photograph, but I have a very bad picture I like nevertheless.

Reader Rick Longworth sent us a largesse of not one, not two, but three wildlife videos he made. Turn up the sound, as there’s music or bird sounds, too. Rick’s captions are indented:

Fox squirrel (Sciurus niger) acrobatics. This fussy female is checking out the left over apples and crab apples from last season. She is very shy of my camera, so I had to shoot through window glass.

 

A pair of wood ducks (Aix sponsa) have been checking out my new duck box. The entrance hole is on the far side, and the female is trying to see if it suits her taste. The drake stands guard and fends off a competing female. I hope they stick around and raise a brood.

Origami artist and physicist Robert Lang has contributed several batches of photos to this site, and today proffers an especially nice contribution of photos and videos. Bocats! I’ll let him tell you about it.

This email combines two of the great passions of WEIT: Reader’s Wildlife Photos™, and kitties! Last year I moved to Southern California, and my studio window looks out into the Angeles National Forest, from which I get regular visitors of the four-legged and winged kind. In January, a mother bobcat (Lynx rufus) and her two kittens visited the meadow outside my window and spent some time playing together, giving me the opportunity to shoot the photos below:

When I asked which were the kittens, and which was mom, and whether there was a color difference, Robert replied.

Yes, the kittens are the oranger ones. In the videos [below], it’s a bit easier to tell, because the kittens are a bit smaller than the mother, but they’re close to full-grown.

But wait! There’s more!

I also shot two videos [JAC: and there are two more below these]:

 

That was early January. In late February, I walked out my front door and another bobcat was sitting about 20’ away. I didn’t have my long-lens camera with me, but shot two videos.

Robert added this:

I’d seen bobcats briefly twice before in the new studio, but usually it was just a glimpse as they went trotting by. This was the first time any stuck around. If indeed the second one was the same female, then it suggests that (a) my meadow is part of her home range, and (b) she’s comfortable with my presence (since she obviously knew I was standing there filming her), so I hope that means I’ll be seeing more of her (and her offspring)!

Note the origami sculpture:

 

When it walks away in the second video, it looks pretty heavy-bodied, which makes me wonder if it might be the same female, pregnant with the next litter (this would be the time of year for that).

This subject is especially fitting for WEIT The Website, because my wife’s copy of WEIT The Book has a hand-drawn bobcat in it, drawn by you in 2012!

Tara Tanaka (Vimeo page here, flickr page here) was so stimulated by some of the comments on her recent video—remarks about why a fishing egret would bob its head and neck—that she produced a new one, also showing a piscivorous bird (an American bittern) swaying its head and neck. I asked her how she thought this behavior was adaptive (if it is), and she replied: “I did some very minimal research, and it’s said to imitate grass swaying in the wind – which makes perfect sense for the Bittern; however, it seems to me that the Great Egret may be trying to distract the prey with the movement of its very visible neck, but that’s just my 2 cents.”

Here are the Vimeo notes; be sure to watch with sound on and the video enlarged:

I had so many comments on the way that the Great Egret moved its head and neck in the Great Backyard Bird Count video that I decided to reach back into some five-year old American Bittern footage that I’d been meaning to edit to show the master of bird swaying.

I regularly change the speed in my videos depending on what effect I’m trying to achieve, but I did want to mention that the flight scene at the very end was slowed down by 50 percent. The Little Blue Heron actually flies at the speed depicted in this clip, but the American Bittern has a very fast wing beat, twice as fast as in this video.

By the way, I’ve also discovered that Tara has a pair of cowboy boots, which are nice ones. Here they are, along with her omnipresent binoculars:
