Transformer Screech Owls - Taking Camouflage to a Higher Level

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.

     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,

     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.

Video of Transformation

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!

Screech Owl not particular interested in humans!
