Biology is Life... and Death...
The words of Dr. Gary Booth have been echoing in my head this week... "Behold, Biology IS life!"
Unfortunately, we have learned this week that biology is also death...
On the exploration of life, our little Wolf Cub Scout went on a delightful nature walk with dad in order to identify four different animals that live in our area. The two of them had a great time! ...
Well, a mostly great time... as long as the pokey weeds stayed out of their socks. But the boys were very successful in finding some beautiful bird life out on the wetlands, including...
Male Mallard duck taking flight.
A Snowy egret striking a pose in the mud.
A blue heron striking almost exactly the same pose.
Lots... and I mean LOTS and LOTS... of these little snails peppering the mudflats.
This little Marbled Godwit spells death for those little snails... watch out for that beak!
After coming home, Larry named these four birds and told me how to identify them--by their color, size, and length of leg or beak. It was very helpful that dad had taken pictures :) Call of the Wild, Requirement 3: COMPLETE!!
During our research we learned that the Bar tailed Godwit (the species on the Asian side of the Pacific) have been known to fly over 7000 miles non stop. One named E7 flew from Alaska to New Zealand in one flight! That such a small bird is the record holder for longest single flight is amazing.
**Fair warning: this rest of this post is kind of a downer...because biology is Also... Death...**
For Xochitl's birthday, we took on a month-long science project: trying to incubate and hatch quail and chicken eggs. We tried this about a year ago with four little chicken eggs... none of them hatched and only one had developed at all. This time, we had 12 chicken eggs and four quail eggs. None of the quail eggs made much progress, but as for the chickens, we were able to witness a lot of growth and learn a lot about the hatching process.
We tucked our little eggs into incubators like this on April 20, to await a hatch on May 11. We turned our chicken eggs twice each day at 8am and 8pm (I know there's a lot of different ideas about how often and when to turn the eggs... that's just what we did) and monitored their temperature closely, just as the incubator instructions said we should...
(The eggs are marked with X on one side and O on the other so it's easy to tell if they've been turned)
About 12 days after starting the incubation, we "candled" the chicken eggs, meaning that we held a bright light underneath them to see if any embryos were forming. It's really amazing!
So we waited. Waited for the little chirps we were supposed to hear from inside the shells. Waited for the eggs to wiggle to and fro as the chicks positioned themselves correctly. Waited and watched for any little pip or crack to appear. Nothing. Day 21 (normal hatch day) came and went... as did days 22, 23, 24, and 25. Our eggs were just as still and quiet as they had always been.
Finally, at the end of day 25, it was time to call it quits. I put on my Biology teacher hat and prepped for the "egg-topsy" to find out if anything had developed.
I'll spare you any nasty details... suffice it to say that most of the eggs had not developed and some appeared unfertilized.
But then there were four... four beautiful fully formed chicks, dead in the shell, who had made it all the way to the last week, but for one reason or another, didn't make the hatch. Was the temperature wrong? Humidity too high? Too low? Not enough air flow? Not positioned correctly? I'll never know...
It was very interesting to examine the first little lifeless chick...but as the second and then the third appeared, I felt that Biology teacher hat falling off as I saw the sad faces of my kids and felt myself get teary-eyed for these little chicks that didn't make it. I knew from the beginning it was a long shot... it's a very delicate and intricate process to get eggs to hatch, but I couldn't help soaring up on the wings of anticipation, hoping for darling little fluffy chicks to appear... I felt invested in their survival, and felt that I had failed them to somehow.
But such is life. Sometimes, the circle of life is very small. Such are the ups and downs of the study of life...and death.
