"First of all, birds don't migrate because of cold weather. They migrate in search of food, open water, or appropriate habitat for breeding. In the case of southward migration this time of year, they are in search for adequate food and water.
Calliope hummingbirds are a very hardy, temperate species that nest as far north as the British Columbia Rockies at altitudes from 4 to 11,000 feet. They are commonly exposed to the elements, so the cold temperatures do not bother them. They have evolved and adapted in cold/cool climates and torpor is frequently used to survive overnight or even during the day in extended cold, precipitous weather events.
We have long suspected that many NW hummingbird species migrate through Missouri regularly. In Christian County alone, we have had Anna's, rufous, and now calliope in the late fall/winter months.Wikipedia has more in depth information about calliopes. Although we tend to think of hummingbirds as nectar feeders, they also consume insects and tree sap when available as well as Greg's sugar water. Seeing an uncommon migrant is a real treat and it was fortunate to have visited Greg where it would be recognized as uncommon.
It is important to note that calliopes are increasingly wintering along the Gulf coast, so it is highly likely that this bird is simply on course and, actually, not even aberrant in timing. We just don't know much about it. It might even be following a migration route that many others of its species have followed from the Rockies to the Gulf of Mexico. That's why it's so important to document these species, and contribute the data to the global avian database."

This bird's rarity quotient brought in birders far from our region. Now the guest register is over 100, and most recent guests were from Austin, Texas, Indianapolis, and a visitor from NYC. Calliope must be the most photographed single hummingbird in Christian County history.
Unlike hunting rabbits and deer, with birders there seems to be an inverse relationship between the bird size and lens length. Whether it is a camera or a magnifier or microscope, the smaller the "game," the bigger the lens or microscope.

Thanks to Greg and the other birders, from KC (Lisa) and St Louis (Doug) and Kirksville (Peter) for the photographs.
