Lately, I've noticed that Caligula (O. Briareus) is more likely to come out of his den if I am wearing white clothing and is more reserved when I wear dark clothing. Just a minute ago, I was trying to get him to come out for a guest. He peered out from behind the rock at me while I was wearing a black sweatshirt. Almost immediately after I took off the dark sweatshirt in favor of my white undershirt, he came out to investigate. I have recorded similar behavior on several occasions. When Caligula is showing dark colors like red and brown he tends to be scared or angry. White and light blue seem to signify calmness. I think he sees my dark clothes as an indication that I might be aggressive and the opposite for light colored clothes. Has anyone noticed this type of behavior? What do you think? Is it just a coincidence?
