Along the migration trail, observers continue to report hummingbird departures. There are clear signs that the females and juveniles, steadily nectaring at flowers and feeders, are getting ready to leave soon. They will need to double their weight to gain sufficient fuel for the journey.
"The number of hummers has been diminishing in the last 5 days. Flowers and plants are drying up and activity at feeders is way down. Last week daily consumption was about one liter. This week it is possibly 1 1/2 cups a day."
