Songbirds fly coop long before tornadoes arrive in
Tennessee[/center]
Thursday, December 18, 2014
By Will Dunham
WASHINGTON (Reuters) – You might want to be careful about who
you call a birdbrain. Some of our feathered friends exhibit
powers of perception that put humans to shame.

Scientists said on Thursday that little songbirds known as
golden-winged warblers fled their nesting grounds in Tennessee
up to two days before the arrival of a fierce storm system that
unleashed 84 tornadoes in southern U.S. states in April. :o The
researchers said the birds were apparently alerted to the danger
by sounds at frequencies below the range of human hearing.

The storm killed 35 people, wrecked many homes, toppled trees
and tossed vehicles around like toys, but the warblers were
already long gone, flying up to 930 miles (1,500 km) to avoid
the storm and reaching points as far away as Florida and Cuba,
the researchers said.
Local weather conditions were normal when the birds took flight
from their breeding ground in the Cumberland Mountains of
eastern Tennessee, with no significant changes in factors like
barometric pressure, temperature or wind speeds. And the storm,
already spawning tornadoes, was still hundreds of miles away.
“This suggests that these birds can detect severe weather at
great distances,” said wildlife biologist David Andersen of the
U.S. Geological Survey and the University of Minnesota, one of
the researchers in the study published in the journal Current
Biology.
“We hypothesize that the birds were detecting infrasound
from tornadoes that were already occurring when the storm was
still quite distant from our study site,” Andersen added.
Infrasound is below the normal limits of human hearing, but some
animals can hear it.
The warblers came right back home after the storm passed, said
fellow researcher Henry Streby, an ecologist from the University
of California, Berkeley.

Golden-winged warblers boast gray plumage marked by patches of
yellow on the head and wings. They weigh about 0.30 ounces (9
grams) and have a wingspan of about 7.5 inches (19 cm).
The warblers spend winters in Central America and northern South
America before migrating back to the Appalachian Mountain region
of the southern United States and the Great Lakes region of the
United States and Canada to breed.

[center]Why woodpeckers don’t get headaches[/center]
Tibi Puiu March 23, 2017
Your typical woodpecker will bang its head against wood 20 times
per second, accelerating 1,200 times more than gravity. In an
average day, a woodpecker does this around 12,000 times. Despite
the serious head banging, the woodpecker suffers no concussions
or any kind of head injury. What’s this bird made of?

[center]Credit: Pixabay[/center]
To get to the bottom of things, a team of researchers from
Beijing and Hong Kong zoomed in on the woodpecker’s behaviour
closer than anyone ever had. The birds were put inside a special
chamber where two synchronous high-speed cameras recorded their
pecking, and a force sensor measured the peck force.
The birds’ heads were also scanned with x-rays and an electron
microscope to image the bone structure. Preserved woodpecker
skulls were also placed in a material testing machine and
crushed for science. This data was then used to build a 3D model
of the birds’ heads which they can then smash in simulations,
without hurting any actual live woodpeckers.
This battery of tests revealed the woodpecker’s skull is
unsurprisingly very sturdy, unlike most birds whose skulls are
fragile. It’s made out of extremely strong, yet compressible
sponge-like bone. The spongy bone is unevenly distributed around
the skull, being most concentrated in the forehead and the back
of the skull. Additionally, the beak and skull are connected by
an elastic tissue which helps cushion the blow.
Inside the skull, the woodpecker’s brain is also armoured.
Unlike human brains which are floating about in a pool of
cushioning cerebrospinal fluid, the woodpecker’s brain is very
tightly enclosed in the skull, with little or no cerebrospinal
fluid. This means its brain doesn’t move about very much and
collision force is spread out evenly over a larger area.
Probably, this is the most important feature that helps
woodpeckers avoid concussions.

and beak bone of the great spotted woodpecker and the lark

woodpecker and (d) lark. Credit: PLOS ONE[/center]
The beak’s construction also helps a lot. The outer tissue of
the upper beak is longer than the lower beak, but the bone
structure of the lower beak is longer and stronger than the
upper one. This overbite divests impact stress away from the
brain and distributes it around the lower beak and bottom parts
of the skull.
When you’re hammering out at over 1,000 g, you better wear some
protection goggles. Woodpeckers have so-called nictitans — thick
membranes beneath the lower lid of the eyes — which protect them
from debris. The nictitans also act as seatbelts for the eyes,
fixing them in place so the retina doesn’t tear and the eye
doesn’t pop right out the skull for that matter.
The high-speed cameras also revealed the woodpeckers vary the
paths of their pecks. As they constantly move their heads and
beaks around, so fast that’s impossible to see with the naked
eye, the birds essentially minimize the number of times in a row
that the skull makes contact in the same point.
The researchers say 99.7 percent of the energy from striking a
tree is absorbed by the woodpecker’s body, and only 0.3 percent
actually impacts the brain. This energy mostly heats the brain,
so to cope woodpeckers usually peck in short bursts with breaks
in between. Researchers suppose these brief breaks serve to cool
the woodpecker’s brain.
Findings appeared in the journal PLOS ONE.

[center]Which Animals Use Starlight to Help with Navigation?
HTML http://dl3.glitter-graphics.net/pub/1726/1726203ha2mjbxeje.gif[/center]
It’s not rocket science, but a male dung beetle’s quest to
navigate a newly-formed ball of dung in a straight line -- in
order to avoid marauders who might steal the dung, and to get
back to his mate as quickly as possible -- does require a
certain amount of expertise in celestial navigation. In a 2013
study published in Current Biology, zoologist Marie Dacke’s team
determined the dung beetle can find its way using only the Milky
Way as a guide. Birds, seals, and humans have been known to use
stars for navigation, but this was the first evidence that
insects can do so, too.

•Researchers placed African dung beetles in a planetarium, and
found that they could navigate just as easily with only the
Milky Way visible as with a full starlit sky. Under overcast
conditions, the beetles lost their way.
•Dacke's previous research showed that dung beetles use the Moon
and celestial polarization patterns to keep moving in a straight
line. Now they know that nocturnal beetles can stay on course
even on moonless nights.
•“It was assumed insects could not use the stars because their
eyes don’t have the resolution to see them,” explains Dacke.
Navigating using the entire Milky Way eliminates the need to see
individual stars, she says.

[/center]
May 4th, 2017 at 5:05 pm by Elena Motivans
Although it looks like a regular salamander, the yellow spotted
salamander is completely unique because its embryos use the sun
for energy. They have algae inside of their cells that give them
oxygen and carbohydrates. This feature that though, of course,
necessary in green plants, is not so common in animals. A sea
slug, aphid, and hornets are other creatures that share this
ability. However, the yellow spotted salamander (Ambystoma
maculatum) is the only known photosynthetic vertebrate! In fact,
before this finding, it was thought to be impossible.
What is yellow spotted and secretly green?
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp
Yellow spotted salamanders actually look pretty normal; they
aren’t green or anything. As the name suggests, the salamander
is black with yellow spots. It is very common in North America.
However, while the embryo is developing it undergoes
photosynthesis. The reason why has to do with the salamander’s
life history. The adults go to pools of water to mate and breed.
Yellow salamanders only breed in ponds without fish because,
otherwise, their larvae would be gobbled up. However, fishless
ponds don’t contain very much oxygen. This problem is solved by
adding algae into the mix.

It has been known for a long time that the eggs have a symbiotic
relationship with algae; the eggs are bright green. Only
recently, a researcher from Dalhousie University in Nova Scotia
discovered that at a certain period in their development,
embryos contain algae within their cells. Part of the green
colour of the eggs comes from the embryos themselves.
A two-way relationship
The algae only move into the embryo after parts of the
salamander’s nervous system has developed. Looking at time-lapse
videos, you can see a flash of green at this time, which is a
small algae bloom. The developing embryo releases nitrogen-rich
waste at about this time, giving the algae food. Some algae
could make it in the embryo at this time.
Once in the salamander, the algae stick near its mitochondria.
Mitochondria create energy for animal cells from oxygen and a
metabolic form of glucose. The algae appear to be giving oxygen
and carbohydrates (the products of photosynthesis) directly to
the salamander cells that contain them. The salamander could be
using these byproducts to help its own energy production. In
return, the embryo gives the algae nitrogen-rich waste and CO2.
The algae have also been found in the oviducts of female spotted
salamanders. The mother may have the algae already and be
passing it down to its offspring by putting it into the egg sac.

Uncommon ability
HTML http://dl3.glitter-graphics.net/pub/465/465823jzy0y15obs.gif
The yellow spotted salamander is the first vertebrate to have a
photosynthetic symbiont. Before, it was thought to be impossible
because vertebrates have an adaptive immune system that should
destroy any foreign biologically material. Therefore, it was
believed that vertebrates weren’t able to have a symbiont living
in them. The spotted salamander may have gotten around this
obstacle by turning their immune system off or by the algae not
being recognised as foreign. However, the real answer isn’t
known yet.
As mentioned, photosynthetic animals are extremely rare and all
of the other known cases are invertebrates. The others use
slightly different methods to harness solar energy, most
commonly by containing some form of microalgae or cyanobacteria
inside of them. For example, the emerald green sea slug, Elysia
chlorotica, even has genes to sustain the chloroplasts that it
contains. It can live for up to nine months without eating
anything :o.

as long as the body.[/center]
A bit differently, oriental hornets (Vespa orientalis) conduct
electricity from their exoskeletons, silk, and comb walls. The
hornet’s yellow bands contain xanthopterin that absorbs light
and turns it into electricity. Unfortunately, this same material
makes an inefficient solar panel.

able to photosynthesize. It has shattered previous perceptions
and [i]opened the idea that other vertebrates may also have a
symbiotic relationship with algae.

[center]Which Animals Have the Best Night Vision?
🐸[/center]
Human vision relies on cells in the retina that are known as
rods and cones. Cones help us to see color, but only when there
is enough light. Rods take over in low-light conditions, but we
see only black-and-white images. Frogs and toads, however, have
two types of sensitivities in their rods, allowing them to see
colors even in the dark. In a series of experiments in 2017,
researchers put frogs in completely dark environments and found
that they were able to discern colors and find the exit -- much
like the conditions they frequently face in real life.
Never in the dark:
“It’s amazing that these animals can actually see color in
extreme darkness, down to the absolute threshold of the visual
system,’ said professor Almut Kelber. “These results were
unexpected.”
In other experiments, researchers studied how frogs and toads
use their color vision when searching for a mate or hunting for
food. Turns out that color means little in the hunt for a
significant other.
Frogs are nocturnal, and their night vision benefits from a
layer of tissue in their eyes called the tapetum lucidum.
Animals with this tissue (such as cats) appear to have
“eyeshine” in photos.

It is absolutely laughable to claim that they "evolved" this
simply because, without it, combined with some other special
abilities only owls have among birds of prey, they would NOT be
able to pinpoint prey not visible beneath snow or foliage,
something they MUST be able to consistently do in order to
survive (owls hunt in conditions, mostly nocturnal, that other
birds of prey cannot hunt in).

er]
Owl eyes are huge in relation to their skull for a very specific
reason (to capture more light in the first place). But that
large eye size works together with another light capturing
ability unique to owl eyes among birds of prey. That is, they
have a lot more rods (needed for night vision) than cones
(needed for daylight color vision), so they lose color vision,
but have extremely powerful night vision.
There is much more to the OBVIOUSLY INTELLIGENT DESIGN of owl
anatomy and physiology, from the larger wings for vertical
takeoffs (for nest defence) and slow, almost hovering, flight
for hunting, to sound absorbing wing and body (owl feathers are
NOT wax covered - not waterproof like noisy duck wing feathers
-, which is the reason owl wings are, with the aid of a couple
of other specialized feather features, nearly soundless in
flight - no other bird can fly as quietly) quiet design to sound
capturing and concentrating facial feathers to 270 degree
pivoting head (including special vertebra that prevent blood
flow from being cut off during extreme head pivots).
It is laughably illogical AND unscientific to claim that owls
"evolved" this set of sensory tools, one by one, at random,
while the "small eyed", "low rod count", "symmetrical ear
placement", "waterproof winged" and so on owls all "died off" as
the "survival of the fittest happy mutations" all came together
in some owls by good Darwinian luck to produce modern day owls.
WHY? Because, as the scientific evidence presented in this video
proves, these abilities work successfully ONLY if they work in
concert. In order for all these sensory abilities to work IN
CONCERT, they had to have been SPECIFICALLY designed to work as
a team. The owl is a night hunter that uses ALL of its
specialized sensory equipment to survive and thrive. Take away
any one of these sensory tools and its survival is in jeopardy.
It is a sad commentary on the willful denial of too many modern
day scientists of God's incredibly complex and beautiful
intelligent design of everything that lives in our biosphere in
general, and owls in particular, that they cling to Darwinian
nonsense.
Too many modern scientists just do not want to hear the truth
that NATURE was created by God.

start, period.

Here's more about the owl, a highly specialized night hunter,
that evidences intelligent design. The shape of owl eyes is
unique. As discussed above
HTML http://renewablerevolution.createaforum.com/general-discussion/darwin/msg12527/#msg12527,<br
/>owls can rotate their head 270 degrees. The owl eye anatomy an
d
physiology is more evidence that the ability to rotate 270
degrees laterally and 90 degrees up and down could not have
"evolved".
WHY? Because the owl head must rotate that much to work in
concert with the owl eyes. They work ONLY as a unit. You see,
the owl eyes are fixed in position. They cannot move.
They are also elongated to enhance night vision by concentrating
the rods along the elongated tube design.
So, the head, the fixed eye position, the elongated eye shape
that concentrates the rods for even more superior night vision
than would be possible with the same rod count (if the eye was
movable and rounded) that enables night vision AND the vertebra
in the neck to avoid pinching off blood flow all work as a unit.
All the separate biological anatomical parts of this unit simply
would not make sense in the absence of all the others. With eyes
that are fixed in the head, the head HAD to be able to turn so
many degrees. The vertebra HAD to be designed to allow normal
blood flow during extreme head rotation or there would be no
advantage to the fixed binocular eyes and 270 neck rotation.
What's more, the differential ear position, combined with the
fixed position of the binocular eyes, though not discussed
below, obviously aids the owl in postioning its body properly to
strike at the prey as it swoops down after pinpointing the
prey's location. You see, the strike of an owl has been measured
at 12 times its body weight. [img
width=50]
HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/1/3-120818180835-1626482.gif[/img]<br
/>It is essential for the owl to be in exactly the right positio
n
to avoid injuring itself when it strikes the prey and the
ground. The video below shows some owls in action. Notice how
the head and the talons are always in the same position relative
to each other when the strike occurs.
[center]
HTML https://youtu.be/pjTfqOrVJRI[/center]
Though not obvious to the casual observer, owls can only strike
that hard in a narrowly defined body position in order to avoid
injury to themselves. That is how they are able to kill their
prey so quickly.
To claim all this magnificent chorus of mutually reinforcing
abilities "evolved" by chance, when they all had to be there at
the same time to work properly, is pseudo-scientific Darwinian
straw grasping baloney.
An owl friend of mine has a few words to say to the Darwinist
true believers:

[center]What’s Unique about an Owl’s Eyesight?[/center]
Owls can rotate their heads about 270 degrees in either
direction, and up and down about 90 degrees, without moving
their shoulders. This maneuverability is key to their ability to
spot prey, especially when you consider that an owl doesn’t have
eyeballs. Their eyes are shaped more like tubes, and are held
rigidly in place by bones called sclerotic rings. Their eyes
consist of densely packed retinal rods -- about a million rods
per square millimeter -- which help them see in all kinds of
light conditions.
The eyes have it:
✔ Owls are farsighted, and they can’t focus on objects
that are very close. Whisker-like bristles located near their
beaks help them detect objects at close range.
✔ Owls have binocular vision. Binocular vision is the
ability to see an object with both eyes, at the same time. This
visual acuity increases the owl’s depth perception.
✔ Owls have three eyelids. The upper eyelid closes
downward when the owl blinks, and the lower eyelid closes up
when the owl sleeps. The third eyelid provides translucent
protection, moving horizontally while still allowing the owl to
see.

The superb lyrebird is one of Australia’s most beloved birds.
The likeness of this peacock-like songbird even appears on the
Aussie 10-cent coin. Aside from the male’s energetic courtship
display during mating season, the lyrebird’s most amazing talent
is its ability to mimic just about any sound. In the wild, males
can flawlessly imitate about 20 different bird species, and can
even re-create the sound of flocks of birds flitting through the
forest. Lyrebirds in captivity have been heard imitating many
other natural and mechanical sounds, such as the click of a
camera shutter, the sound of a chainsaw [img

Lyre, lyre, pants on fire: :D
✔ The crafty lyrebird’s best imitation may be that of the
distinctive laughing kookaburra’s call. Females also sing
occasionally, but not with the same gusto as males.
✔ Lyrebirds living in Australian rainforests sing
throughout the year. They are particularly vocal between June
and August, when they sometimes sing for up to four hours a day.
✔ Lyrebirds live and roost on the ground and have strong
legs and short, rounded wings -- but they’re poor fliers, and
rarely take to the air, except for short stints of downhill
gliding.

Sense of Danger explores the previously unexplained phenomenon
of how animals around the world use their innate senses to
predict approaching disasters. This film produces evidence from
looking at major worldwide disasters, including the tsunami in
Thailand and earthquakes in San Francisco and Turkey. It also
looks at the 1975 earthquake in China, the only major earthquake
in history predicted by animal instinct – which saved 200,000
lives.
Do our animal friends possess a special sense, well beyond human
ability, that serves as an efficient early warning system in
times of danger? [img

/>New Research Has Answers[/center]
The synchronous display of the Photinus carolinus firefly is so
mesmerizing that it draws more than 12,000 visitors a year to
one of the species' chief staging grounds in the Elkmont,
Tennessee section of Great Smoky Mountains National Park. But
despite the event's popularity, many questions remain about how
and why the fireflies are able to choreograph their light show.
To help shine some light, a trio of researchers from the
University of Colorado used 360-degree video recordings and
three-dimensional reconstructions to "quantif[y] and
characterize precisely" key aspects of the fireflies' behavior
for the first time, as lead author Raphaël Sarfati told
EcoWatch.
"There's a couple of results in the paper that we think draw a
broader picture of how fireflies communicate and interact when
they are in their natural environment," he said.
