The Fish and Wildlife Service has a mandate and a trust responsibility to maintain healthy bird populations for the benefit of the American people
2
Why Birds Birds are indicators of ecosystem health Occupy a diverse range of niches Cost effective to monitor Track changes to natural systems Management for birds protect many taxa
3
Birds are important indicators of our environmental health
4
Birds are important to people Pest control Pollinators Recreation 48 million American “Birders” $82 billion in total industry output
5
A History of Bird Conservation
6
Widespread Bird Declines 1800s and early 1900s Bird populations were under tremendous hunting pressure to meet society’s needs
7
No hunting season restrictions No “bag limits” All species could be hunted Widespread bird & egg collecting Unregulated Hunting
8
By the turn of the century ~ 2 million birds were being killed yearly by plume hunters Plume Trade

“A Kentucky flock was a mile wide and passed for 4 hours at a rate of 1 mile/minute giving us an estimate of 230,272,000 pigeons” – Alexander Wilson

MIGRATORY BIRD TREATIES
17
Convention Between the United States and Great Britain for the Protection of Migratory Birds - 1916 Whereas, many species of birds in the course of their annual migrations traverse certain parts of the Dominion of Canada and the United States…
18
KEY HIGHLIGHTS GOAL: assure the preservation of birds Differentiated birds into three groups Game Birds, Insectivorous, Other Non- game Birds Set closed dates for hunting game birds Closed the season entirely all other species Established permits for agricultural pests
19
OTHER TREATY HIGHLIGHTS Established refuge zones Protect birds that “…have common flyways, breeding, wintering, feeding or moulting areas” Enhancing habitat Exchanging research data
20
Species Protected By MBTA Only Species, Families, “groups” mentioned in any of the four Treaties are protected
21
What is a “Migratory” Bird? Ecological: a species that moves between two or more different areas during its annual cycle Altitudinal Longitudinal Latitudinal Long-distance migrant Short-distance migrant
22
Migratory Flyways
23
What is a “Migratory Bird”? Statutory Definition …any naturally occurring native bird …not raised in captivity …listed in 50 CFR Part 10.13 …includes any part, nest or egg of any such bird Distinguishes between “Game” and “Nongame”
24
50 CFR § 10.13 Species are NATIVE Occurs naturally in US or Territory Species/Family covered by one of the four treaties Does not have to be ecologically migratory
25
10.13 List is Dynamic Species can be added with distribution changes Most common reason for addition or deletion is taxonomic changes WRENTIT Family Timaliidae not covered by any Treaty In 2010 put in Sylviidae; a family covered by both Mexico & USSR Will be added to 10.13 with next revision
26
2010 Update Updated taxonomy and species occurrences Added Island Endemics – Hawaii and US Territories 60+ Families covered 1,007 species protected Up from 831
27
Not All Birds Protected What do you mean not all bird species are protected by the MBTA??
29
MBTA Reform Act 2004 Amends MBTA to protect only native species occurrence results from natural biological or ecological processes Requires USFWS to list species (non-native) not protected by MBTA occurrence results from intentional and unintentional human-assisted introductions
30
Bird Species to Which the MBTA Does Not Apply 70 FR 49 Do NOT belong to a Family covered by Treaties Has occurred in U.S. at least once Occurs due to intentional or unintentional human-assisted introductions No credible evidence of occurrence naturally
