(Ammodramus maritimus) Seed Dispersal Pollination Insect Control Human Dependence Birds not only improve the genetic diversity of plant
species, they also contribute to many food and commercially valuable plants that humans depend on. Birds play an important role in insect control,
especially in temperate regions that can be prone
to swarms. Studies in agriculture have shown
that birds can be a farmers natural ally. Habitat destruction, pesticides and disease
have forced the United States into a
pollination crisis. Hummingbirds are one of the primary pollinators in the Americas. The natural habitat of the Seaside Sparrow
is generally salt marshes, using tidal reeds and
spartina grass for protection and nesting material. This species is divided into sub-species, which once included the Dusky Seaside sparrow. In the 1980's, the Dusky sub-species fell into extinction and the species in southern Florida is currently severely endangered.
The Roseate Tern has many obstacles.
In the Caribbean, their eggs are taken
by humans. They are also susceptible
to heavy metal poisoning from the
waters that support their existence.
Human disturbance of beach nesting sites is common in many locations. The challenges Pollution What can you do to help? Become educated about local issues that may impact bird species like wetland development or land management issues.
Get involved. Participate in local pollution clean up initiatives.
Support your local bird conservation agencies through monetary contributions or volunteer your time.
Practice good ethics. If you are a birder, be sure to provide natural and clean food, water and housing for your winged backyard neighbors
Become a citizen scientist! Join an annual bird count and become part of the solution. Pollution from pesticides and rubbish have increased mortality rates due to poisoning & consumption of plastic pieces perceived as a food source by birds. The national Audubon Society has stated that since 1967, the average population of common birds has declined by 68% due to urban sprawl. Intensification of agriculture practices have removed critical land for birds that once used these areas for food, nesting and shelter. 180 species of birds migrate to rainforests from North America each year. As they do, they lose up to 30% of their body reserves on the flight. They depend on rainforests for food, shelter and recovery. Deforestation has had devastating effects. The home range of the Black-capped Vireo extends from the Southern U.S. to Northern Mexico. Due to urban sprawl and agriculture, it has all but vanished from it's most northern range. How is the Scientific Community Helping? There are a variety of methods that ornithologists use to study bird populations. One of the newest and least invasive is Automated Call Recognition (ACR). This technology takes recordings of birds made in their environment and uses computer programs to identify bird species. This helps to determine species abundance and distribution, which is critical for policy makers to write appropriate conservation laws. Roseate Tern
