Why do birds lose their feathers? Here’s when to worry

Let's take a closer look at this pet bird issue

One day, your pet bird has beautiful plumage that looks shiny and pristine, and the next day, their feathers are piling up at the bottom of the cage. It can be very alarming to see your pet suddenly losing their feathers. Don’t panic, though. There are plenty of normal reasons this can occur and you should look into those first.

But dropping feathers can also indicate stress, disease, or other issues, meaning a call to the vet may become necessary. So why do birds lose their feathers? We’ll use the process of elimination to determine the most likely cause.

Is it normal for birds to lose feathers?

Yes, in fact, many birds go through a molt at least once or twice per year (and sometimes even more frequently). On top of that, it’s normal to find the occasional feather lying around. After all, you wouldn’t be surprised to find your dog shedding or your own hair in the shower drain. Much the same way, birds lose their version of hair now and then, especially as feathers get old or break.

However, unlike you and me, avians often drop many feathers all at once. This is to make sure their plumage stays in top shape in the wild, so you will often see birds complete the process right before migrating. In your home, birdie doesn’t have to worry about this so much, but may still go through a molt every so often to replenish their feathers.

If it isn’t part of a normal molt, you’ll have to investigate a few other factors that could bring about a sudden loss of feathers, which may include both physical and emotional issues. Look carefully to see if your bird is pulling at their feathers or if the feathers seem to be falling out on their own. It seems like the difference shouldn’t mean anything, but it can help you to pinpoint the exact source.

While pulling usually stems from a behavior problem, don’t rule something else out. Mites, for example, cause itching and lead to birds grabbing at their feathers even if nothing else is going on. Feathers coming out by themselves can be caused by bacteria and viruses, many of which are very serious. It could also be from something more severe, like a kidney problem. 

Can birds lose feathers from stress?

The short answer is definitely. Birds will pull out a substantial portion of their plumage if something really bothers them. However, it could wind up being really mundane, like a change in your routine, a new pet or baby entering the household, or a shake-up in the environment. Loneliness or boredom can also induce feather plucking, so be sure to keep your bird engaged and happy so that they leave their feathers alone.

What disease causes birds to lose their feathers?

As you might expect, many diseases that affect the feathers cause them to shed unexpectedly. This can include the surprisingly deadly Psittacine Beak and Feather Disease. Don’t worry about this particular sickness too much as it’s quite uncommon in the U.S.

Instead, feather loss is much more likely to stem from bacteria, yeast, or fungus. Many of these occur with other symptoms, such as loss of appetite, that could help you and your vet narrow down the culprit. As mentioned previously, mites frequently lead to feather loss and can be treated once you confirm their presence. You’ll want to work closely with your bird doc to ensure you have the right cause before moving to the solution.

If it’s a yearly molt and everything else looks OK, you don’t really have to do anything. Your bird will work the feathers through on their own, though your pet may need a little assistance with itchy skin. You should also consider providing a little extra protein — it takes a lot of energy and nutrients to replace all those feathers. 

Otherwise, you’ll want to dive deep into the underlying problem and figure out how to fix it. That might mean taking care of whatever has caused the stress or helping assuage a condition. This is when a call to your veterinarian is essential, as they will be able to help you to solve the problem. Some treatments will involve antibiotics or other medicines (topical or oral) that can rid your feathered friend of bacteria that could be causing the feathers to fall. 

Keep an eye on your bird

Anytime your bird starts to lose excessive feathers and you can’t be certain she’s molting, you should check in with your bird doc. They may choose to do a physical examination of the skin and feathers or they might check for underlying conditions by taking blood. You can keep an eye on other signs of their health, such as food intake (and waste), eye brightness, and mood. Monitoring all these things will lead you to the root of the problem (and hopefully a solution) quickly.

Are female betta fish worth it? Here’s why you should consider getting one of these pretty fish
Unlike males, female betta fish can live together, and get along with other fish, too

Betta fish (also known as Siamese fighting fish) rocketed to fame and took a spot as one of our favorite swimming pets for their beautiful color and elegant fins. They, too, are recognized for being aggressive toward each other and will even flare (a display) to you, their owner. However, many of those characteristics only apply to the males of the species, whereas the female versions look and act a little differently. Here's why you should consider bringing one of these lady bettas home.

What are betta fish?
These underwater beauties come from Thailand and live in rice paddies in the wild. It's a myth that they only need a small tank, but bettas often do make great solitary pets that can thrive in an aquarium by themselves. They can also live with many other fish, just not other bettas. One fun thing about these swimmers is that they learn to recognize their owners and will get excited when you come to feed them every night.
How do female bettas differ from males?
You probably know that you can't keep male bettas with others of their kind, as they will fight males and sometimes aggressively mate with females (we recommend only experts breed them). Female bettas won't likely be building any bubble nests though, as that's a job for the males.

We can't get enough of talking birds and we bet you can't either. Humans are eminently fascinated by these creatures who don't just mimic human speech but also human play. In particular, we love to see adorable Peekaboo parrot videos since it's fun for the avians and for us. It's easy for you to teach your feathered friend to play, too, should you so desire.

Posted to the Party Parrot subreddit by u/LeSpatula, this TikTok video is definitely one you'll want to share. While many birdies enjoy a round of Peekaboo, the two ringnecks in this funny bird video have got it down. Of course, they have to get in sync and spend the first few seconds chattering in a pidgin language that seems to be part English and part Parrot. However, by the end, they both know exactly what's about to happen. The two singers dip their heads together, beaks almost touching, and pull up in perfect unison, shouting "Peekaboo." They go in one more time before walking, or maybe strutting, their separate ways.

Anyone who adopts a rodent should know they'll be overwhelmed by the teeth. Guinea pigs in particular have lots of dental needs and often use their chompers to communicate as well. Sadly, you won't see a happy piggy smile, so instead, you'll have to spend some time studying your piggy to decipher the mouth movements.

Oral health can also indicate bigger issues, which means you should keep a close eye on those pearly whites when you hear your pet grind, chatter, bare, or click them. So why do guinea pigs chatter their teeth? There are a few reasons, but none of them are particularly good.
