can someone explain for me why i can hear every single male hummingbird as it
flies to my feeder but never can i hear a female? my feeder is suction cupped
to the outside of the window right above my computer desk about 4 feet from
where i sit and watch them. i assume the males move their wings with a faster
velocity but wondered if anyone really knows why i can hear only the males.
