Readers’ wildlife photos

See new addendum below.

Reader Scott Ritchie photographed a bird in Costa Rica that I also saw there. It’s nearly invisible and was pointed out to us by a boatman. Scott’s captions are indented, and you can enlarge his photos by clicking on them:

A bird of the day from Costa Rica. The Great Potoo [Nyctibius grandis]. They are “related” to frogmouths, and certainly resemble them in looks and behaviour. They sit motionless atop branches, resembling a dead stump. And they have a bizarre nighttime call, ghost-like. Once thought by locals to be a spirit or ghost. At night, they take large insects on the wing.

Can you spot the potoo (an immature Great Potoo) in the 1st picture? I love the old stump festooned with bromeliads and orchids. Atop this the potoo surveys his paddock kingdom.

JAC: This is the most cryptic bird I’ve ever seen.  Note that natural selection has molded not only its appearance but also its behavior: it sits motionless at the end of a branch, looking just like the end of the branch!

But wait! Scott sent two more pictures of a similar species with this caption:

For comparison, here are Papuan Frogmouths (Podargus papuensis) from Cairns (OLD photo). Note chick in first shot.  They like sitting IN the forest in contrast to the Potoo.

Not an AI photo!

I saw a picture of this thing on my Facebook page, and automatically assumed that it–or at least its color–was fake.  But here’s a real photo of the Conehead Mantis (Empusa pennata) from Wikipedia.  An excerpt from the article:

Empusa pennata, or the conehead mantis, is a species of praying mantis in genus Empusa native to the Mediterranean Region. It can be found in Portugal, Spain, southern France, Italy and on the mediterranean coasts of Morocco, Algeria, Tunisia, Libya, Turkey and Egypt.[1] Because of its cryptic nature, or also possibly because of its fragmented, low-density populations, it is rarely encountered in the wild.

They’re incredibly cryptic, as well as patient, as the video below shows:

A short video which shows the main features. Ah, the marvels of natural selection, which, it seems, can do almost anything.

Spot the fawns!

July 6, 2024 • 8:15 am

In lieu of a Readers’ Wildlife today (I’m running low again), we’ll have a “spot the. . . ” feature sent in by reader Charles Schwing.  Here’s his lead-in:

I noticed an adult doe relaxing in our backyard in Napa, California, and chewing her cud. Knowing that this time of year there will usually be a fawn or two accompanying each doe, I started looking. It didn’t take long to spot
one – located where we often see backyard deer. Closer inspection revealed a second fawn.

As I was searching for the young ‘uns, the “Spot the …” WEIT posts came to mind. I especially liked the idea of a “Spot the fawn” challenge since the fawns are themselves spotted. Indeed, it was the spots that caught my eye and revealed the second fawn. I apologize for the low resolution of my 20+ year old digicam. This challenge would be much easier with more pixels. I also wish I’d snapped a pic of mom, but shewas gone by the time I thought of submitting this. Happy non-lethal hunting.

Very often, a mother deer will leave her fawns alone when she goes off to graze, and they remain still while she’s gone, often lying down. If you find one or two fawns alone in the forest, don’t try to rescue them, for mom will be back soon.

Can you see the two fawns in this photo, which I consider “medium hard”.  Please just say “yes” or “no” in the comments and don’t give away their location.  At the very least you’ll see how good their camouflage is.

Click the photo to enlarge it, and I’ll put up the reveal at 11 a.m. Chicago time.

Best-camouflaged animals

Here’s some Friday “gee whiz” evolution. A video showing what the maker, who speaks in what I think is Hindi) considers the “Top Ten Invisible Animals in the World”. But you don’t have to understand Hindi to marvel at how evolution has led to crypsis (camouflage). Note that it involves a combination of evolution of both morphology and behavior.

The list given:

Video Summary:-

1. Oak Leaf Butterfly
2. The Right Eyed Flounder
3. The Buff-Tip Moth
4. The Devil Scarpion Fish
5. Dacorator Crab
6. Eastern Screech Owl
7. Pygmy SeaHorse
8. Leaf Tailed Geeko
9. Leaf Insect
10. Leptocephalus

Spot the hen!

This one is pretty easy—so easy, in fact, that I won’t give the answer.  It’s a photo of a single mallard hen resting under a tree in yesterday’s heat. I put it up just to demonstrate how cryptic these females are in a woodsy situation.  The colorful drakes, of course, would stick out like a sore thumb: the price they pay (via predation risk) for being attractive to the hens. Clearly the risk of predation is outweighed by the “need” to attract a hen.

We have a tripartite piece today, with everyone’s notes and IDs indented:

First, from biologist/naturalist/photographer Piotr Naskrecki‘s Facebook page, a wonderful grasshopper from Mozambique. It was such a good example of crypsis that I asked him if I could post it here, and he kindly gave me permission. His caption:

Although one of the largest insects in Gorongosa, the Gladiator grasshopper (Acanthoxia gladiator) is also one of the most difficult species to find. Not surprisingly so. Its coloration and the body form are designed to look just like a dry stem of grass. Both its head and the abdomen carry long, blade-like extensions (hence the name) that make the illusion complete. The grasshopper fauna of Gorongosa is incredibly rich, with over 160 species that we have recorded so far.

Spot the grasshopper!

A lovely bird from Duncan McCaskill of Canberra, Australia:

Here are a few photos of just one bird, but a very special bird. Back in mid-January, at the height of our severe summer when a lot of the country was on fire, a spectacular and very special bird turned up in a small patch of woodland in Canberra: a Regent Honeyeater (Anthochaera phrygia). The Regent Honeyeater is a critically endangered species, with a population estimated to be only around 350 individuals, scattered over a range exceeding 600,000km2. They were once fairly common throughout south-eastern Australia, and were seen in the suburbs of Melbourne and Sydney, but the population has declined with land clearing of their woodland habitat, and crashed from the 1960s to the point where is it on the verge of extinction.

When the presence of this bird in January was reported in birding circles, birders from far and wide went to see it. It remained in the area for a week or so and seem unbothered by the attention of birders. There were around half a dozen people watching it when I visited.

It was named Regent Honeyeater in the early twentieth century due to its black and gold colouring which is similar to that of the Regent Bowerbird (Sericulus chrysocephalus), which in turn got its name a century earlier due to its resemblance to the colourful attire of the Prince Regent of Britain (later George IV). Prior to the twentieth century, it was known has the Warty-faced Honeyeater, an unattractive but accurate name.

With an insect (I think it’s a winged ant):

The woodland was bone-dry, like the whole region.  Many of the trees looked like they were severely stressed, if not dead. But one large, old Yellow Box (Eucalytpus melliodora) was in flower, and this was the reason the bird was there. Here it is feeding on a flower in the canopy of the Yellow Box:

 

From James Blilie:

I’m not the big wildlife photographer in the family—that’s my son, Jamie. But I did get these this winter.  Birds on one of our feeders in a snow fall.
