New Companion

Thursday morning we got news about a new chicken , a rooster was joining the family. It wasn't until Saturday when my dad, my brother and my mother went to pick it up at a farm near Washoe Lake. Of course  the hens didn't have a clue that their new partner was joining  the clan. I walked outside our backyard to take some cool air and to take a look at the chickens. I wondered what they see when they see us , I made some research to find out what the world is to them. Chickens have tetra-chromatic vision that means that they see 4 different wavelengths(Blue, Red, Green and Ultraviolet) , while mammals are tri-chromatic ;we see only 3 different wavelengths(Blue, Green and Red). That means chickens see completely different things than we do! Their night vision is poor, this is caused by the lack of light sensing cones inside their retina. Their motion sensing is a bit better than humans but not as good as hawks. Birds and mammals have a structure in their eyeball called the fovea. This natural instrument makes the images appear bigger. The second one found in birds is used to make objects at distance look bigger and clearer. Because of this instrument they wobble and tilt their head when their looking at something at distance.
Saturday morning the rooster decided to make its fancy crowing sounds and scared me too death when i was asleep. I woke up frantically asking my brother to put a blanket around it so it " thinks its night" and it will stop crowing.  I made some research on why they crow. It turns out that they just crow when its morning or dawn.

  1. How does seeing the wavelength ultraviolet affect color, would it be like looking throught 3D glass?
