Q: "I heard something about West Nile Virus making birds' feathers fall out - is this true? Why does it happen?"
A: Yes, it's true!
Here's something the average Human doesn't know about birds: when our feathers are growing in, they're connected to an active blood source. The blood provides the nutrients necessary to grow the feather, which is a much more complicated thing than a Human hair. While these feathers are growing in, they're called "blood quills" or "blood feathers", and they look like this:

See the tube that looks kind of like a straw? That's all full of blood as the feather grows. When the feather is done growing, the blood source is cut off, and the feather looks like what you're used to. Of course, while the feather is growing in, it's very important to not break it! Thankfully, we birds have evolved a molting pattern than allows blood quills to grow in with the protection of other intact feathers around it, so it's not much of a problem in the wild.
At the RMRP right now, the Humans are picking up a lot of feathers that look like the one on the right in the cages. So far eight birds have been blood tested and confirmed for the Virus, but there are many more with West Nile Virus symptoms that are awaiting confirmation. The good news is that most birds with WNV can be rehabilitated with supportive care and a lot of hard work from the Humans. However, when birds have feather problems like those above, it can take many months of care for them to grow in normal feathers and be released.
