The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils. Forty-two species have been recorded in Indiana.
Mallards are very adaptable, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. [119] The release of feral mallards in areas where they are not native sometimes creates problems through interbreeding with indigenous waterfowl.
In the mid-20th century, mallards were introduced to Africa and as the invasive population size has grown, concerns over possible hybridization with the yellow-billed duck have occurred. This fear is fueled by other examples of invasive mallards causing localized extinction of other native ducks around the world because of hybridization. [8]
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
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Hoosier National Forest, other agencies and volunteers are mapping where invasive plants are growing in Indiana's Charles C. Deam Wilderness.
According to the International Union for Conservation of Nature (IUCN), 77 bird species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR (v. 2013.2, the data is current as of March 5, 2014 [1]).
Mallards, both domestic and wild in particular are notorious hybridizers, know to frequently hybridize within the mallard complex and even outside of Anas. The willingness to hybridize has concerned conservationists as the gene flow from the mallard may pollute pure populations of more vulnerable species such as the Mexican duck. [2]
