7. Finches are Prone to Air-sac Mite Infection

This condition is caused by air sac mites that infect birds by entering their respiratory tract.

They can block the bird’s air passage that can lead to suffocation and death.

Symptoms of air mite infection in finches and other birds

The symptoms of this condition are not easy to distinguish in mild cases. But you might notice that your bird becomes less vocal, and their feather quality deteriorates.

They may also look fluffed up and less active.

In advanced cases, the symptoms are:

  • sneezing
  • coughing
  • wheezing
  • squeaking (high-pitched noise
  • weakness
  • wet nostrils
  • excessive salivation
  • tail bobbing
  • weigh loss
  • clicking sounds when breathing
  • breathing with mouth open

The symptoms are worse in younger birds and become severe when the bird flies or does other activities.

Causes of Air-sac Mite Infection in Finches

A finch bird can get the air sac mite infection through close contact with other birds who have been previously infected with the parasite.

The disease can also be transmitted when a small amount of moisture containing the mites is released into the air through coughing or sneezing.

Another way to spread the virus is through contaminated drinking water.

Diagnosis of Air-sac Mite Infection in Finches

There are several ways to detect air sac mites in live birds.

The first option is to swab the bird’s trachea and examine the tissues.

After swabbing, the mites may become visible to the naked eye or under a microscope.

They’ll appear as dark dots with the size of a pinhead, through transillumination of the trachea in a dark setting.

Wetting the bird’s feathers above his trachea with a small amount of alcohol may also help you see the mites.

However, just because the mites aren’t visible doesn’t mean they aren’t present.

In some situations, a diagnosis is made when a bird responds to treatment.

Treatments for Air-sac Mite Infection

The most common medications given to infected birds are Ivermectin(in the US) and Ivomec(in Europe).

These medications are toxins, so you need to be careful not to provide too much of these because it can lead to additional health problems.

And in a worst-case scenario, it can cause death.

Therefore, you need to consult your vet to ensure your bird will receive the right amount of treatment.

Note that too little medication won’t effectively treat the infection, and too much can cause too many mites to die off at once.

And that can cause blockage in their respiratory system.

8. Finches Are Quite Pets Compared With Parrots

Finches vocalize like other pet birds, but their voices are tiny compared to large birds like parrots.

So, they would make excellent pets for those who live in apartments and condominiums.

But don’t underestimate their tiny chips because many finch owners say that their soft vocalization is soothing to the ears.

That’s why they love spending time in the same room with their finch.

There’s a free concert from nature right there.

9. Some Finches Can Act As Foster Parents

Most finches are social, but perhaps the most social of them are the Society finch. The name itself explains why.

This finch acts as a foster parent by raising chicks from other species.

And if you’re wondering how this type of finch looks like, well, it seems a bit like a sparrow.

It features white bellies with a brown backside. This finch doesn’t look as gorgeous as other finches, but its friendly nature makes it a desirable pet.

House finch nest with pale blue eggs

Facts About Finches’ Eggs

10. Female house finches’ eggs are pale blue

Perhaps the most exciting fact about house finches is their pale blueish-green eggs with few specklings.

They owe their egg color to the bile pigment’s oxidized form called biliverdin that contributes blue tone to the eggs.

This pigment is deposited as the eggs develop.

On the other hand, the speckles are caused by the protoporphyrin compound that brings red, brown colors and speckles.

The balance in their egg’s color comes with some advantages because the tint of dark colors like blue can protect the embryo from intense light and harmful UV radiation.

On the flip side, dark coloration increases light absorbance and makes the interior heat up, just like the dark car effect.

Therefore, in sunlit nesting environments, less pigmentation will enhance the harmful effect of transmittance, while more pigmentation would increase the damaging effect of absorbance to the embryo.

To say it simply, blue eggs help regulate the sunlight’s effect on developing chicks.

Since house finches lay eggs from late March to late July, they’re prone to sun exposure.

But the composition of their eggs can make the mothers feel at ease.

Scientific Facts About Finches' Color

Scientific Facts About Finches’ Color

11. Male house finches’ rose-colored heads and breasts are caused by their diet

Male house finches’ color varies depending on their diet, not regional differences.

But most adults have rosy red coloring around their face and upper breast with streaky brown back, tail, and belly.

It owes its beautiful red plumage to the carotenoid pigments called echinenone that come from the food they’re eating like berries and produces a red color.

12. Female house finches prefer red-colored males

Most female finches are grayish-brown with blurry streaks and indistinct markings.

But they prefer to mate with red-colored males.

It’s not just because they’re beautiful. But because their head’s color indicates that they can provide the correct type of food for their young chicks.

13. House finches’ with yellow heads lack in echinenone

Aside from echinenone, there are two other types of carotenoid pigments – Beta-carotene, which produces yellow to orange colors, and isocryptoxanthin, which creates orange plumage.

Therefore, yellow feathering in house finches’ heads shows that it feeds on a different food or diet from the rose-colored ones.

It’s a normal diet-related color variation, but as we said earlier, females still prefer rose-colored males.

Fun Facts About Finches and Their Singing Prowess

14. Bullfinches are intelligent enough to learn to sing human melodies accurately.

Here’s another mind-blowing fact about finches.

According to a new study by the late Nicolai Jürgen and academics from the University of Kaiserslautern in Germany, bullfinches learn to sing tunes precisely from human trainers.

They discovered evidence that these birds can successfully match the note sequence they hear to the learned tune in their brain as soon as the human starts whistling again.

When the human partner stops whistling, they anticipate singing the next part of the taught tune and vocalizing it appropriately.

So, the scientists conclude that Bullfinches can cope with the complicated and challenging cognitive challenges of detecting a human song in all of its rhythmic and melodic intricacies.

And have the power to learn the song and sing it appropriately.

Singing Chaffinch

15. Chaffinches have different regional accents

Here’s another fact about a type of finch that can be considered a songbird.

In a study of 723 male chaffinches from 12 different populations across European mainlands, Canaries, and the Azores, US scientists learned a fantastic discovery about birds.

They found out that the further the birds move, the more unpredictable their notes become.

It leads them to conclude that birds develop various ‘accents’ in their song depending on where they live.

Final Takeaways

So, that wraps our list of interesting facts about finches you should know about if you’re planning to purchase one.

Remember that before taking on the journey of becoming a bird pet owner, you need to learn about bird hygiene first.

That can help ensure your bird’s health and safety and your family as well.

It’s worth noting as well that these birds aren’t as cuddly as other birds.

But if you’re not ready for the demands of a parrot, these birds can be an excellent option.

Some finches can be aggressive. So, it would be best to consult an experienced finch breeder first before mixing finch species in an aviary.

And even if they thrive on a pellet-based diet, they still need fresh greens and veggies like vegetables, grubs, egg food, and some seeds.
