One thing I love about visiting my parents in Florida
It got me thinking, (my mind never stops) why are the male birds
We have many goldfinches in the backyard. There's a niger seed mesh feeder that gets a lot of traffic. Sometimes there are 6 or 7 birds feeding with more waiting in the dogwood tree for their turn. The males are bright sunshine yellow while the females are somewhat of a putrid greenish brown color.
My favorite and the most elusive is the Baltimore Oriole. The male is a very flashy bird, bright orange and black. Tonight we had a male and female in the weeping cherry tree. I was thrilled.
The blue jay, another looker, is a rather mean and aggressive bird. They don't share well at all and chase other birds away from the feeder. I couldn't find a picture of a female but I'm sure she's quite drab compared to the male.
I did some checking about this subject and found that the females are the ones attracted to the bright colors. The males couldn't care less about the looks of the females. Very different from the human species. There are less female birds than males and the male has to really look good and stand out so a female will choose them for their mate. The colors make them easier to see also when it comes to territory. Other males can see them and know that this area is taken.
Also birds can see more colors than humans. While humans have 3 cones in their eyes, birds have 4.
