For about 30 minutes this humming bird kept flying up to my tail light. Another one would come and they would fly away but the one kept coming right back.
They associate the color red as food. Get your hummer feeder up!! They're hungry...they're migrating and need that extra food for energy to fly to South America.
River Rat's right......used to see a lot of red 'hot wire' insulators but it turned out hummingbirds were getting zapped, so now they're mostly yellow.
