Also included are: Calliope Hummingbird and Anna's Hummingbird. Some of these wee 3 ½ -4 inch travelers fly from coastal Alaska down to northwestern Mexico every year. They are not only tough but aggressively scary as I have lost many a hair on my head to their obsession with proper nest building. Those little nests contain one to three tiny eggs and are bound with spider silk. They love nectar, a delicious spider, and the color red. But be careful…red food dyes added to sugar water may do a great deal of harm to these wildly popular hovercraft.
