Flock care 101: Recognizing sick birds and taking action​

Bird health watch: identifying sickness

As birds congregate more during seasonal changes, the close quarters at feeders can become breeding grounds for bacteria and mold. Keeping feeders clean mitigates these risks, ensuring the health of visiting birds. Recognizing signs of illness and maintaining feeder hygiene is crucial for maintaining a safe environment for your visitors and protecting your local wildlife.

Other behaviors to look out for

If you are not sure what to look out for, there are some common symptoms that may indicate your visitor is sick. Be on the lookout for lethargic birds, as that often indicates that your visitors are not feeling well. A good rule of thumb is to follow your local news. Often, if there is an outbreak of a disease, you will be prompted to take down your feeders.

Other symptoms to look out for are:

  • Difficulty breathing
  • Poor appetite
  • Unresponsiveness
  • Lack of coordination and loss of balance
  • Drooping wings
  • Dragging legs
  • Twisting the head and neck
  • Fluffed-up feathers. These are not always a sign of illness, especially in winter! If your visitors otherwise appear well, are eating, and are not lethargic, it’s likely that there is no need to worry.

Understanding Avian Health

Not all birds who visit your feeder will be sick. Nature can be tough, and sometimes birds may not look their best but you may not need to worry about them.

Molting

Bird molting is the process where birds shed old feathers to make way for new growth, ensuring their plumage remains in good condition for insulation and flight. This typically occurs annually, but the timing can vary among species; most birds molt after the breeding season but before migration. Expect to see birds looking less sleek and possibly avoiding the feeder as they can feel more vulnerable during this time.

Injury

Bird injuries can occur from various sources such as window collisions, cat attacks, or entanglement in garden netting. Injured birds may appear lethargic, have visible wounds, or struggle with normal movements.
If you encounter an injured bird, it’s best to contact a local wildlife rehabilitator for appropriate care and treatment.
It is also best if you clean your feeder as a precaution after seeing an injured bird. They are more susceptible to illness, so keeping your feeder clean is essential for helping them.
Additionally, take extra care to not run out of seeds, as injured birds may rely solely on your feeder for food.

IMPORTANT!

As some of these diseases can also be passed on to us and our pets, so be sure to always wash your hands thoroughly before and after handling feeders or food and avoid touching your face or mouth while handling them.

Cleaning your feeder

Keeping your feeder clean is essential for the well-being of your visitors.  The high concentration of food in such a small area as a bird feeder is not common in nature, as food is usually more dispersed. As such, there is a higher risk for the food to get contaminated.

Bird Buddy is designed with the safety and comfort of our feathered friends in mind and is incredibly easy to clean.

To effectively clean the Bird Buddy, mix one part bleach with nine parts water. Disassemble and empty the feeder, then soak it in this solution for at least 10 minutes.
Scrub off any debris or mold with a brush, rinse well with clean water, and let it air-dry completely before refilling. Avoid towel-drying as it can leave moisture that promotes mold and fungus growth.

Keep in mind that moisture can lead to the development of mold, which can make the seeds dangerous to ingest by your feathery visitors, so make sure your Bird Buddy is completely dry before placing it back on its perch.
