Sick Birds?

If you feed birds or provide water, at some point, you are going to see sick birds. 

A fellow birder mentioned this week she had some house finches with conjunctivitis, so had removed her feeders for a time, which is exactly what you should do.

How do you know you have sick birds? There are two primary diseases our birds get in this area that are very contagious between birds. 

The first is conjunctivitis. This is prevalent in house finches (House Finch Eye Disease), but can be spread to other songbirds, such as gold finches, purple finches, and occasionally, grosbeaks.. If you are looking at your birds and they have crusty, runny eyes, this is conjunctivitis. Birds can't see well and the disease can cause blindness, if the bird isn't predated first.  The bacterium that causes this disease is spread by direct contact between birds or contaminated surfaces (such as feeders). This disease can be treated fairly easily with the right medication. If you can catch the affected bird, you can take it to Wild Bird Rescue.

Another disease I haven't seen for some time primarily infects doves. You'll have doves sitting on your feeders just gorging themselves, but the bird will waste away because they can't swallow the food. You may notice the birds because it will stay fluffed up like it's cold. Trichomoniasis can be transmitted to birds of prey when the bird eats the dove. Infected birds starve or suffocate. This disease is not easily treatable and generally, birds are immediately put down because the disease spreads so easily.

What you can do. Keep your feeders and bird baths clean as a preventive measure. If you have seen sick birds, immediately take down your feeders and empty your bird bath. Thoroughly clean them, using a 1:10 bleach solution. Leave them down for at least 10 days. Why? You are basically allowing the sick birds in your area to die off to stop the spread of disease. If you put your feeders/bird baths back in operation too soon, any infected birds will once again contaminate your feeders and continue to spread the disease.

These diseases do not infect people.

Summer Bird Feeding

 

Carolina chickadee

Most people don't feed birds (other than hummingbirds) in the summer, but I do. I get it. There is plenty of food available for the birds in the summer and quality bird food isn't cheap. But it's not about the birds, it's about me. I enjoy seeing the birds and having some food available brings the birds to me.

I do reduce the amount of food I provide. In the winter, I have 6 - 10 feeders out, depending upon the weather. In the summer, it's 2 - 4. 

To the left, you can see a Carolina chickadee at one of the feeders. If I have to choose just one feeder, it would be black oil sunflower in a wire tube feeder like this. Black oil sunflower is less expensive than most feed mixes and is enjoyed by almost all songbirds. In addition to chickadees, this feeder attracts cardinals, blue jays, house finches, common grackles, as well as house sparrows and starlings. I don't get many starlings, so it isn't a big deal for me. This feeder also attracts squirrels. You can see the feeders is bent up. That is courtesy of the squirrels. But the squirrels are fun also, and they aren't stealing food out of the birds' mouths, so it's all good.  I fill this feeder once a day in the summer. When its gone for the day, it's gone. The little moochers can go forage after that.

Peanuts for woodpeckers

My other favorite feeder is a heavier metal feeder that I fill with shelled peanuts. The chickadees also like this one, but I have it out mainly for the woodpeckers. I have downy woodpeckers, red-bellied woodpeckers, and occasionally, ladder-backed woodpeckers that visit the feeder every day. Blue jays, wrens, and starlings also are fond of this feeder. Shelled peanuts are expensive, but I use much less of this feed. What you see remaining in this feeder will last at least a week. Probably two. The squirrels don't bother this feeder--no idea why as they do like peanuts. Perhaps it's because this feeder is harder to get the peanuts out of and the feeder is much sturdier, making it harder to get open to pillage as they do the sunflower feeder.

I do throw a handful or two of mixed seed on the ground, more because it is amusing to watch the dogs go crazy than the birds it attracts (My husband calls this me "feeding the chickens" because of the way they go nuts.) Ground feeding does attract doves and great-tailed grackles and occasionally, a robin. The blue jays and cardinals also find this easier than pulling the sunflower seeds through wire mesh.

With temperatures holding around 100 degrees for weeks now, water is much more important than food. We'll talk about that another time

Good birding!

Leucistic House Finch

I looked out my back door and saw a white bird on the ground under my feeders. Of course, I grabbed my binoculars and as luck would have it, the bird and its cohort stayed put (which generally is not how it works.) I grabbed my cell phone and snapped a quick picture. Not a great picture, but if you look closely, you can see the leucistic house finch on the ground.

Leucism is caused by a genetic mutation affecting pigmentation. The birds (and other animals) keep their dark eyes (unlike albinism), but have white patches or are white. Here is a short summary about leucism in birds.
