what are the threats it faces?
Several threats such as shooting and trapping, contaminants and toxins such as DDT, selenium, and methylmercury, etc.
American avocet
Shooting and trapping of American avocets led to population decline until the 1900s. During this time, the species was extirpated from most of the East Coast of the United States. By 1918, Avocets became protected under the Migratory Bird Treaty Act (16 U.S.C. 703-712). Since that time, other threats have emerged. Contaminants and toxins such as DDT, selenium, and methylmercury, have had significant impacts on American avocet breeding success, especially because Avocet chicks are more susceptible to environmental disruptions than adults. The avocet also faces habitat loss. While agricultural and industrial environments have become alternate habitat for the avocet, natural wetlands are decreasing rapidly.
what kind of fish are in the great salt lake in utah UNANSWERABLE is it a freshwater lake or a saltwater lake? Salt water lake what could be the reason for the salinity of this water body? Most of the salts dissolved in the lake and deposited in the desert flats, lake's waters are slightly enriched in potassium and depleted in calcium. where exactly is this water body found? Northern part of the U.S. state of Utah how deep is this water body? In 1963 it reached its lowest recorded size at 950 square miles (2,460 km²), but in 1988 the surface area was at the historic high of . what are some of the biotic components found in this lake? Brine shrimp,  brine flies, and several forms of algae what is the approximate size of the first species mentioned? UNANSWERABLE was there a toxic metal detected in that lake? Yes,  high level of methylmercury what is the effect of the above compound in humans? Ingested methylmercury is readily and completely absorbed by the gastrointestinal tract. It is mostly found complexed with free cysteine and with proteins and peptides containing that amino acid how does that toxic compound affect fish and wildlife? There has been increasing recognition that methylmercury affects fish and wildlife health, both in acutely polluted ecosystems and ecosystems with modest methylmercury levels was there any special bird found in near that lake? Wilson's phalarope, red-necked phalarope, American avocet, black-necked stilt, marbled godwit, snowy plover, western sandpiper, long-billed dowitcher, tundra swan, American white pelican, white-faced ibis, California gull, eared grebe, peregrine falcon, bald eagle how would you describe the appearance of that first avian species mentioned? It is a dainty shorebird with lobed toes and a straight fine black bill, its is is slightly larger than the red phalarope what do they feed on? Small insects or crustaceans what is their conservation status? UNANSWERABLE how would you describe the appearance of that third avian species mentioned in that list? It has has a wingspan of and weighs, the bill is black, pointed, and curved slightly upwards towards the tip.
