June 4 - It looks like the
owlet in the foreground is trying to consume a meal without
interference from its sibling in the background.
|
|
June 3 - It could be that
this little rodent was captured by the owlets, which can begin
capturing prey at about 10 weeks of age.
|
|
June
1 - As the owlets prepare to leave the nest for good, they often
practice "pouncing" on inanimate objects such as the dead prey item in
the box.
|
|
May 31 - The oldest owlet is about nine weeks old. The
parents will continue to feed it for another 3-4 weeks—after that it will need
to hunt for its own food. |
|
May 29 - By mid to late summer these young owls
will be independent of their parents. They face many challenges, especially in
their first year of life, when mortality rates can be as high as 75%. |
|
May 28 - By eight weeks of
age, the only interaction parents have with young is to bring food to
the nest site. The parents remain in the vicinity and roost in a nearby
location.
|
|
May 27 - The cam host has
once again needed to straighten the camera angle. At least we can
confirm that all five owls are still in the box!
|
|
May 26 - Yes, that is how we feel when we are looking at you!
|
|
May 24 -
Whether it is the camera angle or the fact that two of the owls have
already fledged, we have only seen three owls in the box at any given
time in the past few days.
|
|
May 23 - As the Barn Owls spend more of their
time focused on the entrance hole in preparation for leaving the box, we manage
to capture a few partial shots of their now fully developed bodies.
|
|
May 22 - Spreading its wings, one of the owlets exposes the still developing primary and secondary feathers.
|
|
May 21 - Mmmm, dinner. Now
that the owlets are nearly adult size, the parents no longer enter the
nest, but will continue to deliver food items to the nest box.
|
|
May 20 - Space in the box is becoming rather scarce, as even the youngest of the owlets nears its adult weight.
|
|
May 19 - After a day of owlets messing with the
camera, the cam host managed to straighten the camera angle. As a result, we
see all five handsome owlets against the back of the box. |
|
May 17 - Caution: you may get dizzy if you stare at this image for too long. The
rambunctious chicks will not leave the cam alone. They seem to have taken some
enjoyment out of moving the cam out of alignment as well as continuing to stand
right in front of it! |
|
May 16 - "From the tall to the small." The oldest chick is now 49 days old,
first flight usually happens on day 55 and basic plumage is completed around the
same time. The youngest chick is now 40 days old. |
|
May 15 - An interesting image, while casting a pellet one of the owlets frames
the head of his/her sibling to make it appear like it is casting an owl head
instead! |
|
May 14 - FIVE LIVE OWLETS! We finally received our first image showing five live
chicks since the snake attack four days ago. So it appears that the snake only
killed one chick and left the scene hungry. |
|
May 13 - Frequently Barn Owls will remove the heads of prey before swallowing
them whole, but not always. |
|
May 12 - With the
excitement and sadness surrounding the snake attack, it has been
difficult to notice, but the confirmed FIVE owlets are on their way to
becoming handsome young Barn Owls. |
|
May 11 - Cannibalism. Shortly after the
young owlet was killed by the snake, it was consumed by its siblings.
Cannibalism does occur, but usually when the sibling dies of natural
causes.
|
|
May 11 - Dead Chick. We are uncertain if
the dead chick on the floor of the box is the same one that was killed
by the snake. Since yesterday's incident, however, we have only been
able to see four of the six chicks.
|
|
May 10 - Tragedy strikes!
Around 6:30 PM CT a snake got into the box and killed one of the
owlets. The snake is seen constricting the chick while the other five
chicks look on. The left arrow is pointing to the talons of one of the
chicks, presumably trying to fight the snake off of its sibling.
|
|
May 9 - Adult plumage. The owlets moved away from the camera for a grand total of about 3
minutes today to show off some their awkward looking, but fast growing, adult
plumage. |
|
May 8 - Say Cheese! Clearly Barn Owl chicks do not have much regard for observational
science as they continue to make themselves comfortable right in front of the
camera. |
|
May 7 - They may look like they are getting to be full grown, but they still
enjoy a good sleep lying down. They will not start to sleep standing up for
another few weeks. |
|
May 6 - The adult plumage is starting to become very evident on the older
owlets. They should be fully covered in adult feathers by 45 days. This does not
mean their feathers will be full grown, but they will be there none-the-less. |
|
May 5 - The facial disks of the older owlets are
starting to fill out and take on a more adult appearance. The younger chick in
the background still has a very slender look. |
|
May 4 - The female very rarely assists in feeding the
chicks now. This does not mean the younger ones will go hungry however as the
older chicks will often feed their siblings. |
|
May 3 - The older chicks are starting to slow down their
growth rates now as they are nearing their maximum weight, which will be reached
roughly around day 40. |
|
May 2 - Once the female starts to spend less time in the
nest the chicks start to take responsibility for nest sanitization. They scrape
feces and pellets over the edge of the nest with their feet, if the nest design
allows it. |
|
April 28 - At 30 days old some of the chicks are starting to be able to stretch
and flap their wings, but space is at a premium! |
|
April 27 - The chicks have been very active and quite comical as they have
"discovered" the existence of the cam in their box. |
|
April 26 - Contrary to what this picture looks like, there are actually very few
reported cases of sibling conflict among Barn Owls. The only cases of
cannibalism reported are after a sibling has died from other causes. |
|
April 25 - The owlets appear to be well fed as a whole rodent lays at the feet
of the six growing chicks with no real attention given to it for quite a while. |
|
April 24 - The older owlets are starting to show some adult plumage, especially around their faces, wing edges, and legs. |
|
April 23 - The arrows in both images are
pointing to what appears to be a young cottontail rabbit. According to the cam
host, one of the medium sized owlets was able to swallow the rabbit whole,
after many trials and tribulations!
|
|
April 22 - All birds of prey are born covered in small
feathers that puff up and turn into the white down we now see on these chicks.
The adult feathers will then grow on top of this soft layer. |
|
April 21 - Five of the six chicks line up for a family
photo (the sixth is hiding behind the big one). The
nest is starting to get a little crowded! |
|
April 20 - Several of the chicks are starting to display
feathering of the typical heart shaped facial disk that is characteristic of
Barn Owls. |
|
April 19 - Some of the older chicks may be able to eat
on their own now, but "Mom" still makes sure that her youngest gets proper
nourishment. |
|
April
18 - Gulp! By the time the chicks are two weeks old they are able to
swallow some of the smaller prey species whole. Seen here, one of the
older chicks takes down some sort of rodent. |
|
April
17 - For the first two weeks after the female stops brooding she will
continue to partition the food for the chicks, after that they are on
their own to fight over who gets to eat what. |
|
April
16 - With the female gone most of the time now, the chicks will have to
sleep in a huddle to maintain a constant body temperature. |
|
April
15 - One of the older chicks carries a rodent of almost equal size. The
older chicks have started to peck at prey items lying about the nest
box. |
|
April 14 - DINNER! Warning! Do not enlarge the image at left if you have a weak stomach! |
|
April
13 - By the end of the second week the chicks are able to walk around
the box and stand on their own, but they will continue to sleep lying
down until day 45. |
|
April 12 - The female is starting to spend less time brooding the young birds more time away from the nest, especially at night. |
|
April 11 - The female's massive outstretched wing shows, not only
the characteristic banding pattern of the Barn Owl, but also just how
far the chicks have to go before they are ready to "fly the coop." |
|
April 10 - It appears the last chick to hatch was viable and is
surviving despite the tremendous size difference between the siblings
that can be seen in this image. |
|
April 9 - The male's job has been growing in intensity as the
chicks get bigger and require more food. In a week or so the female
will be able to leave the nest and help him. |
|
April 8 - The female "scoops" in all of her owlets for another feeding; an ongoing process with 6 fast growing chicks. |
|
April 7 - One of the older owlets eagerly watches "mom" take apart
a prey item. They will start to eat on their own at two weeks, which is
not far off for the oldest owlet. |
|
April 6 - It is difficult to differentiate the six different
owlets, but the broken egg shell indicates that the final chick has
hatched. |
|
April 5 - When the female is not around to keep them warm the
chicks must huddle together to maintain what little body heat they can. |
|
April 4 - The female insulates the chicks with her wings while she
feeds them and incubates the last egg. She will continue to brood them
until they reach two weeks of age. |
|
April 3 - Unexpectedly, the fifth chick has already hatched. The
nest box appears to be getting pretty cluttered with chicks, eggs,
empty shells, prey items, feces, and pellets scattered throughout. |
|
April 2 - Sometime in the early afternoon the fourth chick hatched. All four can be easily distinguished in this image. |
|
April 1 - The female pulls apart a rodent to feed her hungry, and growing owlets. |
|
March 31 - Right around 8:00PM EST, the female stands over the newly hatched third chick. |
|
March 30 - A nice shot of the female feeding her chicks. In the
first few days the female will feed the chicks shredded pieces of prey
almost every hour. |
|
March 29 - Slightly ahead of schedule the second chick has already hatched! |
|
March 28 - Moments before the top image was captured, the first
chick emerged from the egg!
The arrow is pointing to the naked chick,
which lacks any feathering. In the center image the female
instinctively consumes the left over egg shell.
In the bottom image we
get our first clear look at the newborn owlet in front of the other
eggs. |
|
March 27 - The female seems to be intently watching and moving one
egg for the past several hours, we may have an owlet by morning! |
|
March 26 - A little over 11 hours after consuming a whole rat the female expels a large pellet. |
|
March 25 - The female deals with the remains of a very long legged
bird, an unusual prey species for a Barn Owl. Most of their diet
consists of small rodents. |
|
March 24 - It has been 17 days since the last egg was laid, but we are still seeing the pair mating several times a day. |
|
March 23 - Barn Owls typically eat more than 100 grams of food per day, that is over 20% of their body weight! |
|
March 22 - The average life span of a Barn Owl in the wild is a
little more than 20 months; that means that most adults only go through
one breeding season. |
|
March 21 - We expect the first of the six eggs to begin to hatch towards the end of this month. |
|
March 19 - The male enters the box with a fresh prey item for the female to consume. |
|
March 18 - It seems that "Mom" is getting a little tired of sitting
on the eggs. However, she cannot expect any relief because Barn Owls do
not share the burden of incubation with their mates. |
|
March 17 - Excessive prey, numbering between 30-50 individuals, can
regularly be found in nest boxes during incubation. One box was found
to have 189 carcasses! |
|
March 16 - Unlike most avian feathers, that have sharp, solid edges
that create noisy flight, owl feathers have ruffled edges that enable
almost noiseless flight, giving them their "ghost-like" reputation. |
|
March 15 - The female shows off the flexibility of her neck while
incubating the eggs, a process which typically lasts about 30 days for
each egg. |
|
March 14 - The average wing length of Barn Owls can vary
tremendously depending on the location they are found in, but in
general in the United States they range from 12 -14 inches per wing. |
|
March 13 - The female will continue to rotate all six eggs with her feet throughout the incubation period. |
|
March 12 - Barn Owls are known for having the most sensitive
hearing of all species measured, giving them very precise hunting
skills. |
|
March 11 - Warning! Do not examine closely if you are eating! |
|
March 10 - The male rarely appears in the box anymore except to
drop off food, which he will do in excess throughout incubation. |
|
March 8 - The female appears to be taking a break from incubating in order to stretch. |
|
March 7 - It has been three days since the last egg was laid. Today however, the female laid a sixth egg! |
|
March 6 - Even though the female is sitting on five
eggs, the male will continue to mate with her throughout the incubation
period. |
|
March 5 - The female is seen consuming a cotton rat, a common prey item in this part of the country. |
|
March 4 - Some time within the last hour, the female lays the fifth egg. |
|
March 4 - One of our first few images of a Barn Owl in
Texas reveals the female with four eggs. Because Barn Owls lay an egg
every two to three days, we estimate the first egg was laid on February
24. |
