Footnotes:
(a) Laughing Gull--Northern population required 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.
(h)
Use size 6 on nestling Broad-winged Hawks.
(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; 1A
may be a good fit in Arizona birds.
(l) Use larger size on nestlings.
(m) Band
size yet to be determined by researchers.
(n) Some may require size 9.
(o) 7B for some coastal birds.
(p) Formerly Oldsquaw.
(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 and are indicated as such with an asterisk. 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 recorded as a
remark on the banding schedules (e.g. Mallard x Pintail(?); BWTE x NOSH; MYWA x
? etc.)
(w) Yellow-breasted Chat - size 1A-1B in east, size 2 in west.
(x) Bridled Tern - Band size 3 for southern Caribbean populations
