Are hummingbirds nocturnal

I watched a humming bird, not sure what species as it was 11:30 PM feeding at my white petunia hanging basket in my front yard at Erie Beach, Chatham Kent. Wednesday July 7th, 2010 No google web info on nocturnal hummingbirds, although there is a street light nearby. Possible nest nearby and bird is thinking light equals food. Interesting.
