He then suddenly begins to perform more vigorous Head-dipping movements, and the female, if receptive, performs similar Bill-dipping or Head- dipping movements. -

Anas Platyrhynchos Global Invasive
FULL ACCOUNT FOR: Anas platyrhynchos Anas platyrhynchos System: Freshwater_terrestrial Kingdom Phylum Class Order Family Animalia Chordata Aves Anseriformes Anatidae Common name Synonym Anas oustaleti , Salvadori, 1894 Anas boschas , Linnaeus, 1758 Similar species Summary The mallard (Anas platyrhynchos) is the most common and widely distributed dabbling duck, having a widespread global distribution throughout the northern hemisphere. This migratory species is a highly valued game bird and the source of all domestic ducks with the exception of the Muscovy. Introductions and range expansions of A. platyrhynchos for game purposes pose a threat of competition and hybridization to native waterfowl. Also, recent studies hold the mallard as a likely vector for the highly pathogenic avian influenza virus (HPAIV) (H5N1). view this species on IUCN Red List Species Description Anas platyrhynchos is a medium to large dabbling duck ranging from about 50-60 cm in length and 1-1.3 kg. It is strongly sexually dimorphic. Breeding males bear a distinctive green head, narrow white neck-ring, brown breast, brownish-gray dorsal feathers, pale gray sides and belly, black rump and under tail coverts, white outer tail, and strongly recurved black central tail feathers. Their wings are a pale gray with a distinct iridescent blue upperside and secondaries bordered with white leading and trailing edges, white under-wing coverts, and pale gray undersides. Bills are yellow to olive and legs and feet are orange to red. Females have a broken streaky pattern of buff, white, gray, to black on brown. They have white outer tail feathers and under tail coverts, a white belly, and a prominent dark eyeline. -

Mottled Duck Hybridization by Tony Leukering and Bill Pranty
Mottled Duck Hybridization By Tony Leukering and Bill Pranty Mottled Duck is locally fairly common in the southeast United States on the Coastal Plain from Texas to South Carolina, with isolated outposts in northern Louisiana, southern Arkansas, southeastern Oklahoma, and south-central Kansas. The species’ range extends south from Texas to central Tamaulipas (around Tampico), with some records to central Veracruz. Mottled Ducks also have wandered north of Texas as far as North Dakota (Robbins et al. 2010). Two subspecies have been recognized, although due to similar appearance often merged: nominate fulvigula, an isolated race endemic to peninsular Florida that occurs from Alachua County south, utilizing primarily freshwater habitats; and maculosa in coastal Alabama west around the Gulf of Mexico to Northern Tamaulipas, which favors coastal marshes and inland-prairie wetlands (A.O.U. 1957, Baldassarre 2014). The population of coastal South Carolina and Georgia (and possibly accounting for many of the North Carolina records) was introduced into southern South Carolina from both subspecies (Bielefeld et al. 2010). The Mottled Duck’s range has little overlap with the southern part of Mallard’s “wild” breeding range, but feral populations of “park” Mallards essentially overlap it completely. Hybridization with Mallard is widespread, and one study showed that 11% of Florida birds judged to be Mottled Ducks based on appearance had mixed genetic (“hybrid”) composition, with these “hybrids” accounting for as much as 24% of ducks at one sampled locality (Williams et al. 2005). This phenomenon is considered to be the primary driving force behind Mottled Duck population decline there (FWC 2014). -
Managing Habitat for Mottled Ducks
Managing Habitat for Mottled Ducks Kevin Hartke, Waterfowl and Wetland Habitat Specialist A pair of mottled ducks (female at left) loafing on a cattail hummock. Male mottled ducks are identified by a yellow to greenish-yellow bill while females have an orange bill with or without dark markings. Introduction to the Mottled Duck The mottled duck ( Anas fulvigula ) is a resident duck of the northern Gulf of Mexico Coast with a primary range in peninsular Florida and the coastal portions of Alabama, Mississippi, Louisiana, Texas and northeast Mexico (see range map on next page). It is a dabbling duck, meaning that it feeds mainly at or near the surface rather than diving underwater for food. Mottled ducks prefer coastal marsh and inland freshwater wetlands, but they also can be found in shallow ponds, flooded rice fields, impoundments and ditches. Because of their non-migratory behavior, mottled ducks must satisfy all their life-cycle requirements from these wetland habitats of the Gulf Coast. Unlike most North American ducks, male and female mottled ducks are not readily distinguishable from a distance as both sexes have dark brown feathers with buffy brown edges. Bill color is the most obvious feature to identify sex, as male mottled ducks have a yellow to greenish-yellow bill while females have an orange bill with a dark saddle or spots (see image above). P a g e | 1 Texas Parks and Wildlife Managing Habitat for Mottled Ducks For management purposes, mottled ducks are divided into two geographic populations; Florida and the Western Gulf Coast. Banding data and genetic analyses suggest a lack of interchange or movement of mottled ducks between these two regions. -
