As August ends and September begins, the biggest push south for most Ruby-throated hummingbirds occurs. Males leave first. By departing before females and juveniles, there will be less competition for available food sources. More food will also be available when migrants spread out along the migration flyways.
"We still have several males. They are fattening up quickly so I do not think they will stay for long." Linda Tully P. Highland, Maryland 08/25/15
