I've tried several types of hummingbird feeders, but in my yard they seem to prefer the Perky Pet Four Fountains feeder (seen in video below) more than any other. I think this is because it very closely resembles the Trumpet vine, a native source of nectar. The recipe for nectar is really simple: 1 part sugar to 4 parts water. No red dye is required, and some research suggests that the red dye might actually be harmful to birds. Change out the nectar every couple of days, and you should have swarms of hummingbirds too. As long as there is red on the feeder, they'll find it.
On Saturday, the whole family went to the Gulf Coast Bird Observatory (GCBO) annual Xtreme Hummingbird Xtravaganza in Lake Jackson, Texas. There were hummingbird feeding stations, opportunities to photograph hummers, and even alligators, snakes, and turtles for the children to see. GCBO staff were capturing hummingbirds by placing feeders in a 3-sided cage. After capture, the birds were carefully placed in mesh bags until they could be measured, weighed, and banded. One volunteer told me that the previous week they had banded 52 new birds, and had approximately 30 recaptures.
The GCBO staff and volunteers were all very friendly, helpful, and informative, with one exception. Dr. Wife was holding Boy #1 up to see a hummingbird being banded. She said to my son, "See? He's putting a band on the hummingbird's leg, like a little bracelet." The man banding the birds looked up and said, "It's not a bracelet, it's a band." Dr. Wife said she knows that, and was just trying to explain it to our 2 1/2-year-old in a way he would understand. The bird-bander then obnoxiously said, "Well maybe you should try teaching him the correct name for it." Dr. Wife was speechless she was so mad. I was elsewhere watching Boy #2, but if I had heard it I would have said something. If any GCBO members read this, please let that guy know that his attitude was not appreciated.
