PLEASE SUBMIT ONLY ONE FORM. YOU DO NOT NEED TO SUBMIT ANOTHER FORM FOR EACH SIGHTING.
You will receive a confirmation once this form is received.
Your sightings will be logged in our database. Our research team may reach out to you for more information or to schedule a time to visit for banding depending on our biologist availability and your interest.
NOTE: If you use eBird, we highly encourage you to submit your sighting at
as well. This will greatly benefit our research and the research of other scientists!
How did you hear about our project?
Full address of residence of your sighting (if not at residence, name of location, i.e. "Hulls Gulch Reserve")
Are you interested in having us visit to band your hummingbird for our research if we have a bander in your area?
I'd like more information
How many birds to you believe are present?
Do you know if the bird you saw is an adult male? or a female-plumaged bird? (help with identification can be found here:
When did you first see the hummingbird(s)?
If you're not sure of the exact date, enter your best guess.
Tell us more about your sighting
Include details such as: Have you identified the hummingbird(s) as an Anna's? Do you have any photos? How often do you see the bird? Is it coming to a feeder or flowers?
Biologists "color-mark" the birds they band in 2 ways: by marking the chest with a colored sharpie marker creating a thin colored "necklace" and then they will mark the forehead with a small white dot. (All markings are temporary and begin to disappear during the damp weather and molting.) Please study the images below for clear reference. The sharpie marker "necklace" marking is not to be confused with the color of the gorget, or throat feathers of the bird. These markings make it easier to tell if you have the same visitor or a new one and it also allows biologists to track their movements through the area. We would like to know if you have recently observed a bird with our banding markings on it and what color "necklace" marking you may have seen. As the weather becomes more damp, the sharpie necklace marking will become faded making it more difficult to see a distinctive line. However, the white dot on the forehead tends to last a bit longer. NOTE: The necklace markings will be of varying colors to distinguish individual birds. If you see a marked bird later in the season, do not submit a new form, please email
Yes: I clearly see a white dot on the head and/or a "necklace" line across the chest
No: I do not see any markings at all
I see a bit of smudgy color on the chest and/or bits of white dot on head (see image below)
Faded Color Markings on Head and Chest
Above image is of a banded and color-marked bird that illustrates how faded the sharpie marked "necklace" across chest and the white color on forehead become throughout the winter.
