It's spring and time to bring out the hummingbird feeder.  This is one of the most popular models and there are lots of reasons.  It's a simple design, has six feeding stations, has a shatterproof glass cylinder and holds a whopping 30 ounces!  I've never had a problem with ants climbing down the wire to the feeder (wires are better than string and hold up better in the wind).  Depending on how hungry your many hummingbirds are, the more you'll have to refill the syrup.  Perky-Pets 'high energy nectar' is good stuff, but seriously, a high concentration of sugar and red coloring does the trick.  Hummingbirds are attracted to the color red.
