Talking Turkey

This being the holiday season, it seems appropriate that I break my two-week silence with something seasonal.  How about turkeys?  They are strange, interesting and mostly unknown to us except as a difficult cooking challenge in late November.

First, a little trivia:  turkeys have different names depending on their gender and their age.  Try to match the name to the type of turkey.  Answers are at the bottom of this post.

1. Gobbler a. Female adult
2. Jakeb. Male adult
3. Tomc. Hatchling
4. Poultd. Young male
5. Hene. Male adult (Yes, there are 2 of these.)


Before this spring, the most I knew about turkeys was how to cook one and that Ben Franklin thought they'd be a better choice for our national bird than the bald eagle.  Then one day, on a early spring hike, I got sucked in to the turkey world.  My husband and I both heard a peculiar cackling sound up ahead of us, and as we hiked nearer, the sounds became quite loud.  We easily located the sounds' sources: two tom turkeys up in two trees gobbling back and forth at each other, apparently arguing over who would be a better mate for the next female turkey that should happen along.  The turkeys displayed their stereotypical puffed-up colorful chest and tail feathers, looking like Liberace versus Porter Wagoner. 

My husband quickly figured out that the toms were as willing to gobble at him as they were to gobble at each other.  He had a rather long conversation with the toms, which got more interesting when the husband of another hiking couple joined in too.  What is it with guys and turkey noises?

It turns out that adult male turkeys spend a rather large percentage of their time agitated - either arguing with other males or trying to impress females.  When agitated, they puff up all their feathers and their featherless head skin rapidly changes colors from red to white to blue.  They also have erectile tissue on their faces (of all places!) that stands at attention when they are attempting to attract a mate.  All turkeys have extra flaps of tissue on their faces, but males have the snood (the fore-mentioned face penis), the wattle (hanging under the beak) and the dewlap (webbing connecting the chin to the neck), in addition to caruncles (warty growths on all adult turkeys).  Female turkeys are drab, less warty and less bald - though much more handsome than they sound from this description.

Domesticated turkeys are the same species as the wild turkey, but they have been selected for white feathers, extreme muscle mass, and quick growth.  Domesticated turkeys are so overgrown that it is physically impossible for a male turkey to copulate with a female turkey, and all domesticated turkeys must be artificially inseminated (there's a career for you!).  It is also nearly impossible for domesticated turkeys to fly after adolescence, as they are weighted down by their big, juicy light and dark meat.

Turkeys are social animals, and they will forage for food and hunt for mates in groups when given the chance.  Farmed turkeys grow better and faster when allowed to be near other turkeys.  But when grown with thousands of other turkeys in close conditions, as is the case with the standard large turkey barns, their social behaviors can lead to odd and grisly problems.  Any turkey with the slightest wound to its head will be quickly pecked to death by the other turkeys around it.  A single male turkey in a barn of all females will suffer a similar fate.  A female in a male barn will be trampled by the males attempting to mate.  Strange.  Turkeys are gender segregated and often have their beaks trimmed to reduce economic loss from turkey attacks.

Like the chicken, turkeys have light meat on their breasts and wings, since these muscles are less used by these non-flying birds.  The standing muscles in their legs are used constantly, so they are the dark meat. 

Light and dark meat a few seconds before being eaten.

There tends to be more fat stored in the turkeys' legs, which makes dark meat richer and moister in a cooked bird.  Turkeys are notorious for drying out as they cook because they take a LONG time to cook (much longer than you think).  Since they have so much more muscle mass than chickens, by the time heat from a cooking oven has reached the center of the bird, the outside of the bird has had all its moisture evaporated, becoming stringy and dry.  This problem is made worse by cooking a turkey with stuffing inside the body cavity.  When the bird is stuffed, it basically becomes a big ball of food that can only be cooked from the outside in.  The stuffing often is not cooked thoroughly and can carry salmonella (as my poor cousin discovered the first time she hosted the entire family for Thanksgiving).  Without stuffing, air from the oven can bring heat inside the bird, and the meat cooks from the outside in as well as the inside out.  When the cook bastes the turkey (pours the turkey cooking juices over the cooking turkey) a few times during the cooking process, the white meat can retain more moisture.  The cook can also cook the turkey at a lower temperature for longer to keep the surface of the bird from drying out.  Of course, there's always gravy.


Basting the turkey to keep the light meat moist.
Wild turkeys were over-hunted in the early 1900's, and they were nearly extirpated from North America.  Today their numbers have much improved, and there are enough turkeys to allow hunting in most states.  Estimates of the wild turkey population size in the US are around 7 million birds.  Wild turkeys are vastly outnumbered by their domesticated cousins, as the US produced around 248 million turkeys last year.  That's almost one turkey per person!

Congratulations on sticking with the turkey post.  You will be rewarded with answers to the quiz from the beginning of this post.  Hens are adult females.  Gobblers and toms are adult males.  Jakes are young males.  Poults are hatchlings (which are unusually able to run around and feed very quickly after hatching). 

I promise it won't be as long until the next post.  We'll get back to plants next time.

Of Birds and Meat

I saw two birds yesterday.  One was standing on the pavement next to Lake Michigan, and the other was chopped into bits in a pan in my kitchen (also next to Lake Michigan).

Inland gull hanging out in my town.

Chicken hanging out in my kitchen.
The first bird is a type I see nearly every day as I'm walking around town.  I know it's a type of seagull, though I don't know which type (never was a birder).  Seagulls are found anywhere there's water, not just at the ocean.  When they are found away from the ocean, they're often called inland gulls.  Seagulls are regarded as pest birds by some, but I love them.  They are great scavengers, and this gull no doubt is helping to keep our lake shore clean of all kinds of technically edible trash.  Seagulls are incredible fliers.  I watched one fly during the giant storm last week with gusts of wind up to 60mph, and it was doing just fine.  Since gulls are strong fliers, it means their wing muscles are strong, tough and dark in color (more on this in a minute).

All we have of the second bird to compare it to the first is its wing muscles.  Chicken's wing muscles (not the actual wings, but the breast meat - the part that actually pulls on the wings) are giant by comparison to the gull's, but despite their size, they are weak, flaccid and white.  Chickens don't use their wings, really.  Commercial chickens have been bred to have giant breast muscles, since that's the most commercially profitable part to sell in the US.   Chickens don't fly a lot when they have access to the sky, but when kept in confinement as they grow in a factory, they can't fly at all.  

The white color of commercial chicken breast meat arises from a combination of factors.  First, the genetic characteristic of chickens being more walking birds than flying birds means that their wings aren't adapted to being strong.  Secondly, these birds'  enforced lifestyle is one of all standing or sitting and no flying.  Muscles adapted to working hard, and muscles that are exercised are usually darker in color, most apparent in poultry meat.  Dark meat's color comes from its large quantities of a reddish-brown-pigmented molecule called myoglobin.  Myoglobin does the same thing as hemoglobin (the dark red protein found in the blood), but it is found in the muscles.  Hemoglobin and myoglobin both hold oxygen from the air we have breathed in.  For muscles that work harder and at fast speeds, the need for oxygen is intense.  Having myoglobin present to store extra oxygen means that muscles can work harder and faster.  Muscles can genetically have more myoglobin in them, and the quantity of myoglobin increases with increased muscle usage.

Though I have never eaten or dissected an inland gull, it would probably have dark breast meat, since it uses its wing muscles so much.  If you have ever eaten duck breast, you may have noticed that it was very dark - because ducks are good fliers.  Duck leg meat is usually lighter than the breast meat.

Time for lunch?
