Rare Bird Sighting Form

Bird Identification Tips

Costa's hummingbird

It is very simple to tell the difference between most adult male and female hummingbirds. The majority of males have a solid colored tail and the majority of females and immature males have white tips on their tail feathers. But, there are a few exceptions to this rule. The following species never have white tips on their tails: Green Violet-ear, Buff-bellied Hummingbird, Broad-billed Hummingbird, White-eared Hummingbird and Violet-crowned Hummingbird. On the other hand, both sexes of the Blue-throated Hummingbird have white tips on the tail feathers. Immature males of all species will begin to show bright colors on their gorget feathers in the late summer.

For unusual sightings, biologists need to know the items included on the following form:

• PWD-029a Rare Bird Sighting Report (Word 143 KB)
• PWD-029a Rare Bird Sighting Report (PDF 155.4 KB)

Please submit any supporting files such as photos or sound recordings by attaching to a separate e-mail addressed to Nature. Include in the body of the e-mail your name, e-mail address, county and date(s) bird was seen. The "subject" of the e-mail will already be completed.

If you have a video camera or a 35mm camera with a long-range lens, take a picture. Pictures and sounds are helpful for documentation. A photo is necessary.

Use the diagrams on the "Rare Sighting Report" form to indicate any distinguishing field marks you observed on your “unusual hummer.” Be especially conscientious in describing the colors displayed on the bird.

Texas Hummingbird Diversity and Unusual Sightings

Texans, more than most Americans, have greater opportunities to view many different hummingbird species. Because of our state’s size and diverse ecology which includes coastal, desert, mountain, tropical, forest and grassland areas, eighteen different hummingbird species have been reported. Ten species occur commonly in Texas. If you live in east to north Texas, you will have at least one (maybe two) species during the migratory year. If you happen to reside in West Texas, around the Lower Rio Grande Valley or on the Gulf Coast, you are likely to see three or more species routinely. If you live south, you may even have over-wintering birds. Our publication, “A Quick Reference Guide to Texas Hummingbirds” will help you determine what species you are likely to see in your area. In order for the Wildlife Diversity Program to verify sightings of a rare bird, call (800) 792-1112, ext. 4644. An attached photo will be necessary. Fill out the form below and send it right away. Your description will help biologists determine identification. We will send you a new form. The Roundup has a new group of volunteers who will be called upon to help participants identify and document rare birds when necessary.
