OPINION
PER CURIAM:
Wayne C. Gatling appeals from his convictions for violating the
Migratory Bird Treaty Act. See 16 U.S.C.A.§ 703 (West Supp. 2000)
(making unlawful the taking of migratory birds except as permitted
by regulation); 50 C.F.R. § 20.21(f) (providing that it is illegal to take
a migratory bird "[b]y the use or aid of live birds as decoys," which
includes the taking of migratory waterfowl "on an area where tame
or captive live ducks or geese are present unless such birds are and
have been for a period of 10 consecutive days prior to such taking,
confined within an enclosure which substantially reduces the audibil-
ity of their calls and totally conceals such birds from the sight of
migratory waterfowl."). We affirm.
The government presented evidence establishing that Gatling and
others killed migratory ducks from a pond while a number of appar-
ently tame ducks were present. A government witness testified that
the ducks were tame because they did not flush until he was approxi-
mately 15 yards away from them and they landed within ten yards of
him after they did flush. The witness testified that this behavior was
typical of tame, not wild, ducks. The defendant's own expert con-
curred with this behaviorally-based definition of tame ducks. Viewed
in the light most favorable to the government, see United States v.
Burgos, 94 F.3d 849, 854 (4th Cir. 1996) (en banc), this evidence sup-
ports the district court's factual conclusion that tame ducks were pres-
ent during the hunt and is sufficient to support Gatling's convictions.
See 50 C.F.R. § 20.21(f); United States v. Mebane, 839 F.2d 230,
231-32 (4th Cir. 1988) (affirming convictions for taking migratory
birds through the use of tame ducks as live decoys where evidence
established, among other things, that the ducks at issue were not
afraid of humans or gunfire).
Gatling, however, seems to contend that there can be no liability
under regulation 20.21(f) unless the captive or tame ducks have been
present for at least ten consecutive days prior to the taking. The ten-
day language in regulation 20.21(f) clearly creates an exception to lia-
bility, not a condition for liability. Under the regulation, it is not
unlawful to take a migratory bird in an area where captive or tame
2
ducks are present if those captive or tame ducks have, for at least ten
days prior to the taking, been enclosed in a way that substantially
reduces the ability of migratory birds to hear them and that com-
pletely removes the captive or tame ducks from the sight of migratory
birds.* Unless the captive or tame ducks have been properly enclosed,
the taking of a migratory bird from an area where captive or tame
ducks are present violates regulation 20.21(f) whether or not the cap-
tive or tame ducks have been present for ten consecutive days.
To the extent that Gatling contends regulation 20.21 is vague or
overbroad, we note that he did not make this argument before the dis-
trict court and we decline to consider it here. See Mebane, 839 F.2d
at 232. We have considered Gatling's remaining arguments and find
them to be without merit. Accordingly, we affirm Gatling's convic-
tions. We dispense with oral argument because the facts and legal
contentions are adequately presented in the materials before the court
and argument would not aid the decisional process.
AFFIRMED
_________________________________________________________________
*Such a requirement clearly minimizes the likelihood that captive or
tame ducks will attract migratory birds to a particular area. See Mebane,
839 F.2d at 232 ("Agent Bennett testified concerning the advantages of
using live decoys as opposed to artificial ducks. He explained that the
movement of the live birds and their grouping together created a more
favorable enticement to wild ducks than artificial decoys.").
