The Act

The list

On this page11
It is a lookup, not a fact to remember.

What the list is

50 CFR 10.13, whose stated purpose is "to inform the public of the species protected by regulations that enforce the terms of the MBTA".

Two formats

Alphabetical and taxonomic, so you can find a species by the name you know it by or by where it sits in the classification.

Following a published checklist

Taxonomy and nomenclature follow the American Ornithological Society Checklist of North American Birds, with supplementary reference to the Clements Checklist for species the primary source does not cover.

Which means names change

Taxonomy is revised, species are split and merged, and the list is amended. A name that was right a decade ago may not be the current one.

So this property does not reproduce any of it

A catalog page listing protected species from memory would be wrong somewhere, out of date eventually, and relied on by somebody. The useful instruction is to check the list.

That is a deliberate omission, not an oversight

This library quotes regulations precisely where it can and refuses to paraphrase where paraphrasing would be acted on. This is the clearest case of the second.

What you actually need to know

The species of bird the feather came from. Everything else follows from that one fact and a lookup.

Which a supplier should be able to tell you

And if a supplier cannot say what bird a material came from, that is an answer about the supplier.

Other statutes reach other materials

CITES, the Endangered Species Act and the Lacey Act can each apply to exotic tying materials independently of the MBTA. None of them is read here and none should be assumed to be satisfied by this page.

The practical route for a working tyer

Buy from the mainstream trade, which sells domesticated poultry, and keep the exotic and inherited material questions separate and properly advised.

16 U.S.C. 703(a), the Migratory Bird Treaty Act. Unless permitted by regulation, "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, possess, offer for sale, sell, offer to barter, barter, offer to purchase, purchase, deliver for shipment, ship, export, import, cause to be shipped, exported, or imported, deliver for transportation, transport or cause to be transported, carry or cause to be carried, or receive for shipment, transportation, carriage, or export, any migratory bird, any part, nest, or egg of any such bird, or any product, whether or not manufactured, which consists, or is composed in whole or part, of any such bird or any part, nest, or egg thereof" as specified in four bilateral treaties. law.cornell.edu
Written from 16 U.S.C. 703(a) and 50 CFR 10.13, and from the catalog as it stood on 19 October 2026. This property does not say which species are on the protected list, because that is a lookup against 50 CFR 10.13 rather than something to assert from memory. CITES, the Endangered Species Act and the Lacey Act can each reach exotic tying materials independently and none of them is read here.
