National Band & Tag manufacturers bird bands ranging in size from a hummingbird all the way up to a swan. We manufacture bands for the USGS Bird Banding Laboratory that are used by researchers across the United States to track multiple species of birds. The bands we produce for the USGS are Federal Bands, but we also produce Non-Federal Bands (NB&T Bands) for those who want to band their own birds or use the bands for a promotional (non-bird) use. The chart below shows the differences between the two types of bands. You can also view our Size Comparison Chart of Federal VS NB&T bands to find the band with the correct measurement for your needs.
