If, on the other hand, your sunflower and morning glory plants are mature, I suspect that the birds may be going after insects on the leaves rather than the eating the leaves themselves. Check the plants for insects. If it seems like this could be the problem, it can probably be easily remedied just by spraying the plants down every few days with a stiff jet of water from the hose. For a serious infestation, you can apply an organic insecticidal soap to the leaves or make your own using 2 Tbsp of liquid dish soap and a gallon of water. Apply this in the morning and be prepared to rinse it off the morning glory leaves after a few hours to prevent the leaves from getting burned by the sun.
That's true, sunflowers are for the birds! But if you prefer to enjoy them yourself, try stringing some aluminum pie plates up in the same area of your plants. The reflection and the noise seems to deter birds.
I, also, forgot to mention that the red birds and other seed eaters will eat the sunflowers right off the plants. I love to watch them going all over the flower and hanging up side down to do this.
Bluebirds are insect eaters and I agree that they are prized visitors. I am an avid bird watcher and belong to a national bird group. I agree with the post about them eating pests and they are the real culprits. You are soooo lucky to have bluebirds.
Well birds like seeds and sunflowers are a great place to get them.What I have seen some people do is cover the sunflower bloom with a white gauze material.Air and sun can get in but the birds have a difficult time getting the seeds thru the gauze.I don't think it has to be white but I have never seen it any other color.
I posted yesterday; but don't see it, so I will post again!
I strongly suspect that if you look at your plants closely, you will see bugs/caterpillars of some sort are actually doing the damage; and the bluebirds are eating the real culprits.
Bluebirds are prized visitors to the garden, where they eat a variety of pests. I have never heard of them eating the plants!
Take a good close look; I bet you'll be glad you didn't chase the blues away!
