Are bird respiratory systems really more sensitive?

Are bird respiratory systems really more sensitive?

It’s generally regarded as a fact that birds have very sensitive respiratory systems, far moreso than humans. Much of this comes from the proven sensitivity of birds to smoking Teflon products.

When heated to temperatures above 260C (500F), this otherwise stable material emits several flourinated prolysis products that are known to be rapidly lethal to birds.

The Avian Respiratory System: A Unique Model for Studies of Respiratory Toxicosis and for Monitoring Air Quality—Environmental Health Perspectives—Harvard School of Public Health—February 1997

However, an extensive and exhaustive study in a journal called Environmental Health Perspectives by the Harvard School of Public Health paints a much more nuanced picture. The article starts with a detailed look at the entire respiratory system of birds, then looks at orally administered toxins, inhaled particulates, and toxic gases.

The general summary is that the bird respiratory system is not uniformly more problematic than ours. Sometimes it behaves similarly to humans, sometimes it’s more sensitive, and sometimes less.… READ THE REST

Arguments against wing clipping

Arguments against wing clipping

There are some topics in the bird community that are very controversial and for which opinions are very divided. Wing clipping is near the top of the list.

It’s not hard to find articles weighing the pros and cons of wing clipping, so I wasn’t wanting to write another one. However, I feel that in these articles, important downsides to wing clipping are not mentioned. To have an honest debate, all the arguments need to be on the table.

Here’s just one example. The article only presents one downside: lack of exercise. The text I quoted makes people feel bad about not clipping wings and typical of articles you’ll find.

If you care about your parrot and want to keep them safe, then clipping their wings is generally a good idea. Whether your parrot stays inside 24 hours a day, 7 days a week or not, the bottom line is that you don’t want your parrot to fly away where they can get into harm’s way.

Learn about your bird in the wild

Learn about your bird in the wild

There are many resources on keeping birds in captivity. Most people search online but there are also books and magazines. However, these resources typically don’t mention much about how various bird species live in the wild.

The reason this is important is that unlike dogs and cats, birds are significantly less domesticated and some argue they are not domesticated at all.

An important distinction to make is that learning to behave nicely around humans is very different than being genetically programmed to like humans! Usually, domesticated animals mesh well with human lifestyles because the animals have been selected to like people. A domesticated dog puppy with limited experience near people will still approach humans for affection and play because thousands of generations of dogs before it were allowed to breed only if they were friendly toward humans.

What’s it like to have a pet bird?

What’s it like to have a pet bird?

I used to breed cockatiels starting in the early 1980s, selling over a hundred birds a year. I used to advertise them in some town papers with my phone number.

When people called, I would find out whether this would be their first bird. If so, I would give them my standard speech to make sure they knew what they were getting into. Maybe 25% of the time, they would decide to think about it more before buying a bird and in some cases they would decide a bird was not for them.

Get the variety pack!

Here’s what I would tell them:

  • Birds are really messy! There’s really no getting around it. Feather dust, feathers when moulting, seed strewn everywhere, chewing on everything they can find, and they seem to find a way to poop in impossible locations.
  • With very rare exceptions, birds don’t like to be pet like dogs, cats, or rabbits.

What about euthanasia?

What about euthanasia?

There are sharply divided opinions about euthanasia and I’ve grouped them into 3 categories that I’ve encountered.

  1. Euthanizing an animal is fine if they are sick, annoying, or you just want to try out a different pet
  2. Euthanasia is a final option if all medical options are exhausted and the bird is on the edge of death (this is typical in humans)
  3. Euthanasia should be applied to animals that are suffering and there are no available options to alleviate it other than a lifetime of painkillers

There is also the added issue of financial burden. Categories 2 and 3 are evaluated differently if medical options are unaffordable.

With a blog called Free Range Parrots, I predictably believe in the third option. Part of being free is being free from unending suffering. How do you tell if your bird is suffering?

  • It’s not playing or singing or chirping much
  • It’s fairly inactive
  • It acts much better after giving a painkiller, indicating they are in considerable pain
  • Sometimes you can just intuit it by looking at the bird

Euthanising a bird is an extremely difficult thing and obviously should be given a lot of consideration.… READ THE REST

Animal research into fat, carbohydrates, and disease

Animal research into fat, carbohydrates, and disease

Many of us has grown up believing that fat makes you fat and that fat causes heart disease, diabetes, metabolic disorder, and obesity. A low fat diet has been recommended by the USDA, doctors, and nutritionists since the 1980s despite lack of solid research to support it.

This opinion has been mirrored by the bird world where processed (pelleted) diets are universally low in fat and high in carbohydrates. Also, feeding fatty seeds like sunflower and safflower is highly frowned upon.

However, research going back to the early 20th century contradicts this conventional wisdom, but has always been drowned out by organizations such as the American Heart Association, the USDA, and the Sugar Association, all of which have strong industry ties.

In the last 15 years, an avalanche of research has predominantly exonerated fat, including saturated fat, from causing these diseases. Carbohydrate intake was the culprit all along. Low carbohydrate diets aren’t very controversial anymore but the link between high consumption and disease is now much more ironclad.… READ THE REST

Animal research applied to parrot diets

Animal research applied to parrot diets

While there is a good amount of research on wild birds, there is precious little on captive birds. We do have a lot in common with birds, however:

  • Overall human health, especially in western countries, and captive bird health is poor
  • We share most of the same important internal organs and they perform the same functions
  • Many very common diseases in humans and other animals are also common in birds
  • Especially in the United States, we are both advised to eat a low fat, high carbohydrate diet (USDA, AHA, and others)
  • When our birds are ill with diseases in common with humans, we are typically given the same proposed remedies

The food for thought here is whether, given the similarities, we can apply this animal research on diet to captive birds.

Here is a short list of diseases we share that are at least partially influenced by diet:

  • Cancer
  • Diabetes
  • Fatty liver disease
  • Gout
  • Heart disease
  • Heart attacks
  • Kidney failure
  • Obesity (metabolic disorder)

I’m dipping my toe into a difficult topic here: bird diets.… READ THE REST

Hygiene hypothesis and birds

Hygiene hypothesis and birds

This is a food for thought post. What’s now called the Hygiene Hypothesis was first proposed in 1872 and was studied in depth in a well known study from 1989:

“Over the past century declining family size, improvements in household amenities, and higher standards of personal cleanliness have reduced the opportunity for cross infection in young families,” the paper continued. “This may have resulted in more widespread clinical expression of atopic disease, emerging in wealthier people, as seems to have occurred for hay fever.”

Hay Fever, Hygiene, and Household Size—British Medical Journal—1989—David P Strachan

Although the theory fell out of favor for awhile, it’s returning and is well described in a new book which is excerpted in the New York Times this month.

What does the immune system do when it’s not properly trained?

It can overreact. It becomes aggrieved by things like dust mites or pollen. It develops what we called allergies, chronic immune system attacks — inflammation — in a way that is counterproductive, irritating, even dangerous.
