Species Table and Recommended Band Sizes

The table below is sorted by species number. If more than one band size is listed, the preferred recommended band size is listed first.

Sort by any of the columns in ascending order by clicking on the column header.

To sort by any column in descending order, click the column header a second time.

{SpNumber} {AlphaCode} {CommonName} {BandSize}


(a) Laughing Gull - Northern population requires the largest size.
(b) Frigatebirds and Northern Hawk-Owl require 7A or 7B short due to the short tarsus length.
(c) Other Hybrid Ducks require band sizes worn by all species of ducks; bander determines appropriate size for each bird.
(d) Sora and Virginia Rail, Avocet and Stilts--Band above the intertarsal joint only.
(e) Eurasian Collared-Dove and White-crowned Pigeon require 4A short due to the short tarsus length. This band may be a better fit for other large pigeons as well.
(f) Vultures and Condor can not be banded with metal bands--request “Vulture” bands for reporting auxiliary marked birds.
(g) Band hawks and owls with lock-on bands when band size is 4 or larger. Some small owls may not require lock-on bands.
(i) Band eagles with rivet bands only.
(j) Do not band parrots with butt-end bands, use special parrot bands.
(k) Size 2 bands need to be filed to a shorter height for Green Kingfisher; 1D may be a good fit in Arizona birds.
(l) Use larger size on nestlings.
(m) Use 4 short for Northern Saw-whet Owl
(o) 7B for some coastal birds.
(q) Except Eastern x spotted towhee
(r) size 6 is the preferred size for the northern subspecies, barrovanius
(s) size 4 is appropriate for southern populations.
(t) Hummingbird band sizes were revised in 2002 to reflect a new description of band sizes as reflected in S. M. Russell and R. O. Russell 2001. The North American Bander’s Guide to Banding Hummingbirds. North American Banding Council (Point Reyes, California). Some sizes are tentative. Use caution when banding these species and advise the BBL of the appropriateness of the recommended sizes.
(u) Male Black-chinned Hummingbirds breeding in southern Texas may require size XS.
(v) For all hybrid codes the suspected parentage (or parent if only one is obvious) must be reported as a remark (e.g. Mallard x Pintail(?); BWTE x NOSH; MYWA x ?; etc.)
(w) Yellow-breasted Chat - size 1A-1B in east, size 1D,2 in west.
(x) Bridled Tern - Band size 2,3 for southern Caribbean populations
(y) Nazca Booby - Band size unreported since split from Masked Booby; please advise of correct band size.
(z) Stainless steel bands (4.2-4.3 mm) internal diameter recommended for Common Terns.
(aa) Incoloy bands 4.0 mm internal diameter recommended for Roseate Terns. Tern researchers found more band loss from the slightly larger stainless steel band.
