Also, the paucity of morphological differences between the Old World mallards and the New World mallard demonstrates the extent to which the genome is shared among them such that birds like the Chinese spot-billed duck are highly similar to the Old World mallard, and birds such as the Hawaiian duck are highly similar to the New World mallard.

The icterids are a group of small to medium-sized, often colorful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. Thirteen species have been recorded in Indiana.
Asian bush honeysuckle can choke out native plants and destroy natural food sources for birds and wildlife. Asian bush honeysuckle is one of Indiana's most common invasive plants Skip to main content
Black-bellied whistling ducks ingest a wide variety of plant material (including corn, rice, millets, several types of weeds, and other grasses), [17] but also consume arthropods (such as insects and spiders), [17] aquatic invertebrates (such as snails and other molluscs) and tadpoles [17] when available. They often feed on submerged vegetation ...
Hoosier National Forest, other agencies and volunteers are mapping where invasive plants are growing in Indiana's Charles C. Deam Wilderness.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
Turkey vultures at the Indiana Dunes. This is a list of birds of the Indiana Dunes. [1] The Indiana Dunes (state park and national park) protect over 15,000 acres (61 km 2) of dunes and shoreline. From the barren sand beaches to the inter-dunal ponds and the intervening forest, this area is inhabited by 271 identified species of birds.
In flight, the lack of a white border to the speculum is a key difference. The American black duck is darker than most mottled ducks, and its wing-patch is more purple than blue. The behaviour and voice are the same as the mallard. Mottled ducks feed by dabbling in shallow water, and grazing on land.
