This Ruby-throated Hummingbird has been feeding every day lately from the Trumpet Vine off my deck. This is either a female or a young bird from this year as there are no ruby colored feathers on the throat.
This picture shows how long the tongue is as it prepares to enter another flower for more nectar.
The Trumpet Vine flowers are long and it looks like this hummingbird needs its head, neck, bill, and tongue to get to the nectar at the very bottom of the flower.
It would visit each flower and then return an hour later for a second visit, and then repeat this all day.
The Hummingbird would often rest in the Lilac Bushes nearby after working the flowers for ten or fifteen minutes, as seen in the picture below.
