Eastern Screech Owl Camouflage and Defensive Techniques - A Mini-Documentary. YouTube videos of a White-faced Scops-Owl "performing" by being frightened (i.e. abused) into changing it's appearance on a Japanese TV show for laughs led to names such as Transformer Owl, Evil Owl, Dracula Owl etc. In fact, many small owls use "Concealing Postures" or the German word "Tarnstellung" to survive in a very hostile world. Perhaps the very best small owl that does this and so much more is the relatively little observed or studied Eastern Screech Owl. Hours of footage over two years of one female Red-Morph Eastern Screech Owl guarding her nest box in Florida were combined into this short mini-documentary so that these amazing creatures can be appreciated for their tenacious survival instincts and dedication to raising their young in a natural environment.
The Real, Wild "Transformer Owl "! They have been called Transformer Owl, Shapeshifter Owl, Evil Owl, Dracula Owl etc. In fact, many small owls use "Concealing Postures" or the German word "Tarnstellung" to survive in a very hostile world. Far from evil or scary, they are amazing small creatures that have unusual adaptive ability to change their appearance. Perhaps the very best small owl that does this and so much more is the little observed or studied Eastern Screech Owl. Hours of footage over two years of one female Red-Morph Eastern Screech Owl guarding her nest box in Florida were combined into this short mini-documentary so that these amazing creatures can be appreciated for their tenacious survival instincts and dedication to raising their young in a natural environment.

A Green Lacewing Larvae uses its prey's corpses as camouflage. I noticed this strange creature moving on our Mango Tree and took a closer look. When it is still you can not see it as it attaches the bodies of ants, aphids, small beetles and some of the smallest spiders I've ever seen to its back in a pattern to blend in with the mottled tree bark of the Mango tree. How it does this must be an amazing sight - there are literally dozens of dead bugs attached to its back. The larvae is known to attach debris to itself and is sometimes called the "trash bug". This blog goes into more detail on this fascinating insect. Apparently sightings of this behavior are rare as the disguise is so effective. In the video you will see how the bug blends right in with the tree trunk. And this little bug really moves fast even though it is extremely top-heavy, so it is difficult to get clear video and stills without injuring it - I briefly captured the bug for filming and then returned it to the tree to continue its beneficial work of preying on aphids and the like. This is one of the most beneficial of insects and one can buy the larvae to help control insects on fruit trees and gardens. I do not use pesticides on the trees as it indiscriminately kills beneficial insects - I just let nature take its course. "Whistling Down the Road" courtesy of YouTube audio library.
Note: We were fortunate enough to make some fantastic observations and videos of unique Screech Owl behavior in our backyard during the nesting season this past May. These dynamic little owls are a lot more complex and intelligent than any literature I've read gives them credit for. This Blog will be edited with more details and analysis over time.
We hoped the Screech Owls were going to come back this spring after success in 2011. However, in late December 2011 the nest box was taken over by squirrels and stuffed with twigs. After cleaning it out, wood rats tried to move in, and then the squirrels started coming back - that's a story for another blog post. It was clear the location up on a 12 foot high 2x4 on our back fence in the woods wasn't going to work - it was a jungle back there and there was no chance of a successful season with the box in that location. As a last resort, I put the nest box only about 8 feet off the ground at the gable end on an aluminum outbuilding in January, installed the nest cam and we waited. Not the best location, but a safe location that no critters could get to.
The grey male and red female could be heard, and occasionally seen, courting in early March. They were first seen inside the box on March 10th and the first egg was laid on March 13th - success! Everything went smoothly with lots of activity inside the box and frequent nighttime feeding by the male Screech Owl. The female only left the nest briefly at night - a routine had set in.

A video showing the parents on the job in the positions in the photo above
April 18th - I walked around the back of the "shed" and came face-to-face with a big pair of yellow eyes about 6 feet off the ground right in front of me at eye level - stopped - what was that? - and then it was gone. I approached slowly and it was the male grey Screech Owl. He would not look at me, I backed off and he squinted, but didn't move. I left him alone, but came back each evening and walked slowly along the fence line looking in the dense oaks and pepper trees and found him there each day in various different positions and started to film him at a distance with a telephoto lens He had probably been there since March waiting to start hunting and feeding as soon as it got dark,

Transformer Owl Part One - The "Predator" Effect.
Looking at the tapes from May first I saw the cloaking behavior from the male owl similar to when we first met, although not as extreme as I saw that first night. He was apparently reacting to me watering the plants and moving closer with the hose as the video ran on a tripod. This is shape-shifting at its best. He never really "warmed" up to us over two months and never once faced us with both eyes fully open.

Transformer Owl Part Two - Extreme Danger
The red female Screech Owl moved out of the nest box for the most part on May 2nd as it was getting hot and crowded in there. She set up her post to guard the nest in a Palmetto Tree near and above the nest where she could come to the rescue during the day if needed. She did an amazing job of finding spots with red color that she could blend in with. But she was in the open in the daytime - a very dangerous position for her. Here she spots a large Red Shouldered Hawk on the house rooftop - she is at 12 feet and looking up - the reaction here is fierce and immediate. In the daytime the big hawk could have her for lunch in a heartbeat The Hawks rule the daytime skies - the Owls the night!

Red Shouldered Hawks in the backyard use the same perches in the daytime that the owls use at night!
Transformer Owl Part Three - Mild Danger - Amazing Slow Transform
The red female had found the perfect spot to sit in the daytime on the cut end of an old reddish brown Palmetto Branch next to another red/brown branch. Here a large Raccoon rummaging around in the daytime is scared and runs through a pile of old wood and brush and climbs the fence right below the owl. She is initially on high alert by the noise and then assess the situation and slowly transforms into a branch as the Raccoon walks by on the fence just below. Since the Raccoon was so close a slow but complete transform seemed to be her choice to avoid attracting attention.

Transformer Owl Part Four - Minor Threat
Later the same Raccoon is walking along the fence below the red female and you can see by her reaction she is on guard and does a slight transformer move as she does not sense significant danger - but she is watchful and ready.
Not Too Worried
Transformer Owl Part Five - Meh - You are not worthy! Here I'm coming to get the camera after running 14 minutes of video and as I come around the shed into view the female is initially mildly concerned, but when she sees it's me she give a rather indifferent expression and goes back to relaxing. Their situational awareness and ability to parse threats and respond to many different scenarios is amazing!
