“You’re a bird-brain!”
Did you ever hear that? It’s a derogatory statement and meant to degrade someone. But I identify with it because I am learning a lot from my fowl friends – my five chickens.
I’ve noticed that the birds often gather at the fence and look in the direction of the kitchen window. When I move around in the room, their heads follow my movements and they seem to be waiting for me to come out. But when they are standing in bright daylight, how can they see me through a window in a room with subdued lighting?
It was research time.
Of the many documents on the internet, I found an article by Cynthia Berger published on July 19, 2012 titled “True Colors: How Birds See the World.” That was an eye-opener. Using a device called a spectrophotometer (it measures light that is reflected from a surface), researchers found colors in the UV range that most birds can see.
Quoting from her second paragraph, “…systematic testing of bird vision revealed something unexpected: many bird species can see UV light. Scientists also have learned that many birds have plumage that reflects UV light.”
I had never thought about chickens being able to see differently from humans. Oh, I know chickens have enhanced hearing and smelling, but enhanced sight? Amazing.
I’ve always wondered how a bird can distinguish a male from a female, but now I know. Both males and females of barn swallows, mockingbirds, western meadowlarks (and many others) look remarkably alike to humans. But viewing them through the spectrophotometer we find they look totally different from each other. They, of course, have the same shape but different coloring. Another example: To humans, the blue tit male looks identical to the female. But looking at the UV reflection, we find a bright spot on the males’ head. The female spots that immediately and says “That’s my man!”
Female birds know which eggs are hers because various eggs reflect UV light differently. Choosing to raise her own offspring, some females either break or eject foreign eggs from her nest.
Birds will more readily eat food that reflects greater amounts of UV light. That explains another question I had: why do my chickens go for corn more than wheat? Corn reflects more UV. Also, insects reflect a higher amount of UV than green grass. Watch out, moths and bugs; my chickens are loose in the yard and you are doomed!
Speaking of moths, it’s fun to watch a hen run at full speed then half jump and half fly with neck fully extended to grab a moth or other flying insect out the air.
But all that helps to explain why the birds are at the fence looking in my direction: some of my clothing is reflecting UV light. They see me through the window, and they assume that I’ll bring food out to them. Sorry, chicks. I’ll feed you later.
When I think of birds’ ability to see what humans cannot see, it reminds me of spiritual sight. In Ephesians 1:18, the Apostle Paul said, “I pray that the eyes of your heart may be enlightened, so that you may know the hope to which God has called you, the riches of his glorious inheritance in the saints.”
“Eyes of your heart”? Sounds strange because blood-pumping hearts don’t have eyes. What Paul means is we have inner understanding, insight, the discernment or comprehension of spiritual reality as it pertains to Almighty God, and verified in the Holy Bible. I am not referring to Hinduism, Buddhism, spiritism, spiritualism, other religions, or any New Age idea. I am not talking about mindless concepts that exalt man, nature, familiar spirits, or demons.
An example of a mindless statement – proclaimed to be spiritual insight by Matshona Dhliwayo – is: “The Universe is one body; love is its heartbeat.” Not understanding either the universe or love, Dhliwayo is wrong on both counts.
True spiritual insight comes from God, and enables us to understand real life – both temporal and eternal – from God’s perspective. Second Corinthians 2:16 informs us that we can “have the mind of Christ”; that is, receive His thoughts. This requires us to stop being self-centered, and to become God-centered or Christ-centered.
As birds can see some of what humans cannot see, we can ask God to grant us wisdom and insight which would enable us to understand what we normally cannot “see”. That’s not being a bird-brain; it’s being in tune with God.
