For your answer we went to an expert at the University of Kentucky.
Sadly, Dr. Thomas Barnes, a professor and specialist in wildlife at UK,
says hummingbird populations are declining across the world, because we
are destroying their habitats in Central America and Mexico.
In addition, last year violent weather blew hummingbirds migrating
across the Gulf of Mexico off course. They ended up going further west
and north for their breeding. They tend to migrate back to their birth
place nest, causing the numbers to possibly be down in our area.
The good news is hummingbirds are migrating right now so if you put up a
feeder chances are Dr. Barnes says you should see them for the next
month or so.
