The temperatures are going to really drop this week here in northern Ohio and have already started to take the fall. I've noticed the cardinals are hanging around more.
As you can see this guy loves feeding from a sunflower lantern. It seems no matter what time of day I look out back there he is. There's about four other males that show up each day along with three females, but this guy has claimed the lantern as his.
One female sits in my fly through all day to avoid the elements. She will fly to a near by tree or my fence when I come out to put fresh food out but the minute I'm back inside she's back in the feeder.
As far as the Safflower experiment it's working great. The cardinals as well as some finches visit it but the starlings and sparrows leave it alone.
If your looking to attract cardinals to your back yard feeding is pretty simple. They prefer a large enough feeder where they can perch comfortably. Try either a hopper feeder, fly through or a lantern type like I'm using in this photo.
As far as food goes they prefer black oil sunflower seed, safflower seed, sunflower chips and even some cracked corn. I also often see them eating peanut halves from my fly though feeder.
You can always tell when they are breeding (which can happen up to four times a year) because the male picks up a seed, hops over to the female, and the two momentarily touch beaks as he feeds her and she takes the food. Mate feeding will continue through the egg laying and incubation phases of breeding. I love sitting out back and watching it.
As for their nest they use twigs, bark strips, vines, leafs and paper lined with fine grass and hair placed in dense shrubbery or among branches of small trees 1-15 feet above the ground. Around here I notice they use the neighbors pine tree allot.
As you can see they do not really require allot to attract and really add some nice color to your yard. If your not feeding them now, try some black oil and safflower and if their in the area it will only be a matter of time before they find it and become regulars in your yard.
