Photo about Fulvous whistling duck Dendrocygna bicolor swims in a pond in Naples, Florida. Abstract: A breeding population of fulvous whistling-ducks (Dendrocygna bicolor) has become established in south Florida, representing an increase in Florida's resident waterfowl resource. [33], The fulvous whistling duck has expanded its range in the West Indies, and into the southern US. It feeds during the day and at night in fairly large flocks, often with other whistling duck species, but rests or sleeps in smaller groups in the middle of the day. They are whitish and on average measure 53.4 mm × 40.7 mm (2.10 in × 1.60 in) and weigh 50.4 g (1.78 oz). They are found on the African, Asian and the two American continents. Reply.

TOTH, Pesticide Research Laboratory, University of Florida, Gainesville, FL 32611 Abstract: Thirty fulvous whistling-ducks (Dendrocygna bicolor) collected during 1984-85 from the Ev- erglades Agricultural Area (EAA) of south Florida were analyzed for organochlorine and organophosphate The fulvous whistling duck had escaped my grasp over the years. The Indian subcontinent is the Asian stronghold. No obvious courtship displays. It has no recognised subspecies, although the birds in northern Mexico and the southern US have in the past been assigned to D. b. helva,[5] described as having paler and brighter underparts and a lighter crown than D. b. [20] This species has strong colonising tendencies, having expanded its range in Mexico, the US and the West Indies in recent decades with northerly range expansions into California in late 19th century and rice-growing regions of the U.S. Gulf Coastal Plain in the early to mid-20th century, given its affinity for rice-growing areas. Separate populations of fulvous whistling ducks occur in Asia, Africa, Madagascar, South America, and North America. [2] They were an early split from the main duck lineage,[3] and were predominant in the Late Miocene before the subsequent extensive radiation of more modern forms in the Pliocene and later. There is a year round population in central Florida and a western Gulf of Mexico population with a summer breeding range along the coast in Texas and Louisiana. In recent years, these ducks have become year-round residents in all of peninsular Florida. Since 1968, black-bellied whistling ducks frequently have been found in central and south Florida in late summer and early fall, sometimes mixed in flocks of fulvous whistling ducks. They will breed in southeast Texas and southwest Louisiana and migrate along the Gulf to Mexico. [5], The fulvous whistling duck is found in lowland marshes and swamps in open, rice fields, flat country, and it avoids wooded areas. I finally splashed one in STA 1W a couple Saturdays ago.

It has whitish stripes on its flanks, a long grey bill and grey legs. [5] Eggs may also be added to the nests of other species, like ruddy duck. [20] The calls of males and females show differences in structure and an acoustic analysis on 59 captive birds demonstrated 100% accuracy in sexing when compared with molecular methods. Fulvous Whistling-Duck (Dendrocygna bicolor -- Family: Anatidae) STA-5, south of Clewiston, Hendry Co., Florida 03/15/2008 In South Africa, nests may be within 50 m (160 ft) of each other, and breeding densities of up to 13.7 nests per square kilometre (35.5 per square mile) have been found in Louisiana.

However, in a study in Louisiana, 25% of the diet of incubating females consisted of cereal. [27], Both sexes incubate, changing over once a day, with the male often taking the greater share of this duty. It is not normally a mountain species, breeding in Venezuela, for example, only up 300 m (980 ft),[18] but the single Peruvian breeding record was at 4,080 m (13,390 ft). 2008.

[19] The population appears to be declining, but the decrease is not rapid enough to trigger the vulnerability criteria for extinction. Despite hunting, poisoning by pesticides and natural predation by mammals, birds, and reptiles, the large numbers and huge range of this duck mean that it is classified as least concern by the International Union for Conservation of Nature.
