If You Touch a Baby Bird, Will Its Mom Abandon It?

When I was a kid, our living room opened out onto a back deck through a set of French doors. A pine tree stood over the deck, providing a home for countless birds. Baby birds would regularly fall from their nests onto the deck, and would lie there crying in full view of my brother and me as we sat on the floor watching TV. Our parents always told us that we should never attempt to rescue these birds, no matter how long they were out on the deck, because our scent would cause their parents to reject and abandon them.

Some of these babies would get their act together and find their way back into the nest. Some would get dragged off by neighborhood cats. A few got plucked off the deck by hawks (and, once, devoured as I watched). Whatever happened to the birds, though, my brother and I dutifully listened to our mother.

These days, I feel bad about that. It turns out my mom is full of baloney.

Scent of a Human

Birds will not readily abandon their young because they “smell humans.” For one thing, birds don’t have a great sense of smell. Their olfactory bulbs are small and simple compared to other animals (although this wasn’t always the case, and there are exceptions to the rule, like the turkey vulture, albatross and kiwi), and they’re not going to be able to pick out your scent from all the other smells hitting their beaks at any given moment.

Even if they could detect your scent, and make a negative association with it, they’re not just going to up and leave. You wouldn’t abandon your kids and home at the first sign of danger, would you? Even if you didn’t love either all that much, you already went through the trouble of painting the living room and changing all those dirty diapers, right? Birds will make that same simple economic decision. They’ve invested a lot of time and energy in those babies and they’re not going to give them up for nothing. Mess around with a nest before the eggs are laid or before they hatch, and a bird might re-nest elsewhere, but once the kids are in the picture, they’re no push-overs.

Rescue Mission

So, my mother is obviously no ornithologist, and she’s not your mom, so feel free to ignore her advice. (Sort of. Let me explain.)

There are two types of baby birds you’re likely to encounter on the ground: nestlings and fledglings. Nestlings are featherless or fuzzy and are too young to leave the nest. Fledglings have their feathers and are old enough to leave the nest and be on the ground, making their first bold steps away from home under the watchful eye of mom and dad.

Fledglings you should leave alone. They’ll usually sit around for a few days outside the nest before their flight skills develop enough that they don’t need their parents. If you’ve got a fledgling near your home and are worried about predators, ask your neighbors to keep their cats inside. Hawks? Well, that’s just the circle of life.

Nestlings, though, could probably use a helping hand. Pick them up and put them pack in the nest, and their parents will not think any less of them if they smell a little bit like a human. What you should not do is take the little guys inside and try to care for them yourself. Sure, you’re at the top of the food chain. You’re smart and civilized and have dominion over the natural world. But you are not a bird. You will make a lousy bird mom.

What’s the Difference Between Prison and Jail?

Many people use the terms jail and prison interchangeably, and while both terms refer to areas where people are held, there's a substantial difference between the two methods of incarceration. Where a person who is accused of a crime is held, and for how long, is a factor in determining the difference between the two—and whether a person is held in a jail or a prison is largely determined by the severity of the crime they have committed.

A jail (or, for our British friends, a gaol) refers to a small, temporary holding facility—run by local governments and supervised by county sheriff departments—that is designed to detain recently arrested people who have committed a minor offense or misdemeanor. A person can also be held in jail for an extended period of time if the sentence for their offense is less than a year. There are currently 3163 local jail facilities in the United States.

A jail is different from the similarly temporary “lockup”—sort of like “pre-jail”—which is located in local police departments and holds offenders unable to post bail, people arrested for public drunkenness who are kept until they are sober, or, most importantly, offenders waiting to be processed into the jail system.

A prison, on the other hand, is usually a large state- or federal-run facility meant to house people convicted of a serious crime or felony, and whose sentences for those crimes surpass 365 days. A prison could also be called a “penitentiary,” among other names.

To be put in a state prison, a person must be convicted of breaking a state law. To be put in a federal prison, a person must be convicted of breaking federal law. Basic amenities in a prison are more extensive than in a jail because, obviously, an inmate is likely to spend more than a year of his or her life confined inside a prison. As of 2012, there were 4575 operating prisons in the U.S.—the most in the world. The country with the second highest number of operating prisons is Russia, which has just 1029 facilities.

What Do Morticians Do With the Blood They Take Out of Dead Bodies?

Zoe-Anne Barcellos:

The blood goes down the sink drain, into the sewer system.

I am not a mortician, but I work for a medical examiner/coroner. During an autopsy, most blood is drained from the decedent. This is not on purpose, but a result of gravity. Later a mortician may or may not embalm, depending on the wishes of the family.

Autopsies are done on a table that has a drain at one end; this drain is placed over a sink—a regular sink, with a garbage disposal in it. The blood and bodily fluids just drain down the table, into the sink, and down the drain. This goes into the sewer, like every other sink and toilet, and (usually) goes to a water treatment plant.

You may be thinking that this is biohazardous waste and needs to be treated differently. [If] we can’t put oil, or chemicals (like formalin) down the drains due to regulations, why is blood not treated similarly? I would assume because it is effectively handled by the water treatment plants. If it wasn’t, I am sure the regulations would be changed.

Now any items that are soiled with blood—those cannot be thrown away in the regular trash. Most clothing worn by the decedent is either retained for evidence or released with the decedent to the funeral home—even if they were bloody.

But any gauze, medical tubing, papers, etc. that have blood or bodily fluids on them must be thrown away into a biohazardous trash. These are lined with bright red trash liners, and these are placed in a specially marked box and taped closed. These boxes are stacked up in the garage until they are picked up by a specialty garbage company. I am not sure, but I am pretty sure they are incinerated.

Additionally anything sharp or pointy—like needles, scalpels, etc.—must go into a rigid “sharps” container. When they are 2/3 full we just toss these into one of the biotrash containers.

The biotrash is treated differently, as, if it went to a landfill, then the blood (and therefore the bloodborne pathogens like Hepatitis and HIV) could be exposed to people or animals. Rain could wash it into untreated water systems.
