believed to live up to 20 years or more in the wild.
The Bald Eagle, our National Symbol, occurs throughout the United States, Canada, and northern Mexico.
Bald Eagles are present year-round throughout Texas as
spring and fall migrants, breeders, or winter residents.
The Bald Eagle population in Texas is divided into two
populations- breeding birds and nonbreeding or
wintering birds. Breeding populations occur primarily in the eastern half of the state and along coastal
counties from Rockport to Houston. Nonbreeding or
wintering populations are located primarily in the
Panhandle, Central, and East Texas, and in other
areas of suitable habitat throughout the state.
Habitat loss and pesticide intake over the past 200 years
are the factors most consistently associated with declines
in Bald Eagle populations with the ultimate threat to Bald
Eagles being people. Human populations are expanding
in Texas. People are attracted to water which is the primary
areas for eagle nesting and foraging. People also consume
huge volumes of fresh water which reduces the amount of
water available in river and wetland systems. Some eagles
are showing more acclimation to the presence of people,
but most are found in more rural settings with minimal
human disturbances.
Shooting has long been recognized as a major
human-caused factor in the decline of Bald Eagles.
Although primarily fish and carrion eaters, eagles were
thought to be a major threat to chickens, livestock,
and game animals. Consequently, many were killed by
farmers, ranchers, and hunters. In 1940, Congress passed
the Bald Eagle Protection Act, which made it illegal to
shoot or harass eagles. In 1969, Bald Eagles gained further
legal protection under federal endangered species laws.
With heightened public awareness and sensitivity to the
plight of the Bald Eagle, coupled with strict laws, shooting
mortality has declined from 62% of total reported deaths
from 1961-1965 to 18% from 1975-1981. Although this
