Karolyn Warfel: I'm Karolyn Warfel with Perky-Pet Wild Bird Feeders and I'm talking about how to make your yard bird friendly. And now we're talking about hummingbirds. There are a variety of shapes and styles in the market. Most them are red in color which is a known attracted to hummingbird. First one I have is a bottom fill feeder. This is about an 8 ounce reservoir that you simply unscrew the bottom of the feeder, fill with nectar screw the bottom back on, and then invert the feeder to hang it. This particular model has a B-guard on it. And this prevents them from getting inside the port. This next style is also a bottom fill feeder, but it has the added bonus of an ant moat. You simply fill the ant moat with water and it prevents the ants from coming down the feeder and into the nectar ports. It also has perches. Hummingbirds will feed with or without perches. You can have them, but you don't have to. This next style is a top fill feeder with sports bottle functionality. You simply push down on the feeder to close up the ports, open the lid, pour in your nectar put the lid back on tightly to create the vacuum seal, and pop up the reservoir and the feeder is ready to use. The next style is a dish Hummingbird feeder. This feeder has two compartments that come apart, you simply fill it with nectar, put the top back on, and hang the feeder, there is no inverting necessary. It's important to keep your Hummingbird feeders in the shade to protect your nectar from swelling. And you want to put it around Hummingbird friendly flowers that are pink, orange, and red.
