On opening day of the Maryland dove hunting season, agents of the United States Bureau of Sports Fisheries issued a violation notice to the defendant. Chew was charged with exceeding the daily bag limit of 12 doves, and was tried and convicted by a United States magistrate. We affirm.

Federal agents watched the Bragel Farm near Baltimore, Maryland, on September 9, 1972. They saw Chew and three companions hunting mourning doves, a federally-protected species of migratory birds. Two agents later testified that they saw Chew kill and retrieve 19 doves. The third agent said that Chew killed and retrieved 22 birds. Since the daily bag limit for mourning doves was 12, Chew was cited by the agents for violation of federal hunting laws.1

Chew consented to be tried before a United States magistrate pursuant to 18 U.S.C. §§ 3401-02. The magistrate found that Chew had killed and retrieved 11 birds, and that he had also shot and killed ten other doves which he could not find and did not retrieve.2 On April 17, 1973, the magistrate found Chew guilty of exceeding the daily bag limit, sentenced him to a prison term of 30 days, suspended, and imposed an 18-month probationary term conditioned upon payment of a $350 fine and requiring that Chew refrain from hunting migratory game birds during the probationary period. Chew appealed to the district court and thence to this court.

The only issue briefed is the constitutionality of the regulation under which Chew's conviction was obtained. Chew contends that the regulation is unconstitutionally vague.

The Migratory Bird Treaty Act, 16 U.S.C. § 703 et seq. provides in part:

Unless and except as permitted by regulations made as hereinafter provided in sections 703-711 of this title, it shall be unlawful at any time, by any means or in any manner, to pursue, hunt, take, capture, kill, attempt to take, capture, or kill . . . any migratory bird. . . .

Applicable regulations in effect on the date of the offense provided that "no person shall take in any one day, more than the daily bag limit . . . ." 50 C.F.R. § 10.24 (emphasis added). At the time, 12 was the daily bag limit for mourning doves. 50 C.F.R. § 10.103(a). "Take" is defined by regulation to mean:

(d) Take. Pursue, hunt, shoot, capture, collect, kill or attempt to hunt, shoot, capture, collect, or kill.

We agree with Chew that this definition is vague, ambiguous and overbroad as applied to a "bag limit." Read literally the regulation could be said to put in one's "bag" a flock of 13 doves flying overhead if one pointed his gun at them. It is urged that a regulation susceptible to such an absurd interpretation fails to give notice of that forbidden and is thus an affront to due process.

But Chew was not cited for merely pointing his gun at birds. He killed, by his own admission, at least 21. The regulation clearly equates "kill" with "take," and it is thus an offense to kill more than the daily bag limit. As applied to killing birds the regulation is precise and unambiguous. In cases where a statute or regulation is vague in its application to the conceivable range of human conduct but clear in its prohibition of specified, particular acts, one whose conduct falls within the narrow prohibition may not complain of its overall vagueness and generality. Young v. American Mini Theatres, Inc., --- U.S. ----, 96 S. Ct. 2440, 49 L. Ed. 2d 310 (1976); Parker v. Levy, 417 U.S. 733, 752-61, 94 S. Ct. 2547, 41 L. Ed. 2d 439 (1973); Broadrick v. Oklahoma, 413 U.S. 601, 610-11, 93 S. Ct. 2908, 37 L. Ed. 2d 830 (1972); United States v. Raines, 362 U.S. 17, 21, 80 S. Ct. 519, 4 L. Ed. 2d 524 (1960).

As applied to Chew's conduct, the definition of "take" is sufficiently precise. Chew killed more than the daily bag limit of mourning doves. This is forbidden, and the conviction is accordingly affirmed.

At oral argument in this court Chew's attorneys contended that it is the universal custom among hunters to regard only birds killed and retrieved as included within the daily bag limit and that the regulation should be read in the light of custom. Since he retrieved only 11, he insists that according to the common understanding among hunters he actually "took" one less than the bag limit. Chew also claims that his method of computing daily bag limit has traditionally been employed by the Bureau in issuing violation notices. He suggests that evidence developed since his trial indicates that the strict language of the regulations is not generally enforced, and that hunters are not prosecuted unless found in possession of more than the daily bag limit.3 Chew urges that, the constitutionality of the regulation aside, he is the victim of arbitrary enforcement.

Chew first raised this point by a "Motion for New Trial on Appeal" filed in the district court. In this motion, filed after the district court had affirmed his conviction, Chew asserted that "the Appellant wishes to offer additional evidence which has been educed subsequent to the aforesaid hearing as to the implementation of the guidelines of the Department of the Interior." The district court denied the motion in a Memorandum and Order dated November 5, 1974, on grounds that (1) there was no indication that the proffered evidence was either "newly discovered" or probative, (2) there was no jurisdiction in the district court to grant the motion pending appeal,4 and (3) there was no jurisdiction to receive evidence or conduct a trial de novo in the district court sitting as an appellate court from a magistrate's decision. We have not jurisdiction to consider the question for Chew did not appeal from the denial of his motion for a new trial.

AFFIRMED.
