Size Matters Among Bowerbirds

All the world’s a stage” wrote the Bard and now we find it’s true for flashy bowerbirds as well.  Havent we, at some time, marveled just a bit at the bower bird’s attention to presentation and detail. According this report male bowerbirds select the size of objects to enhance the perspective effects of distance from the perspective of the female.  These effects exist in the fun houses of amusement parks and museum dioramas.  Bowerbirds use the effect to make the male seem larger.  How do the birdbrains do that?

About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
