We review the distribution of White-cheeked Duck Anas bahamensis rubrirostris in mainland Ecuador and show that the species is expanding its range significantly. Contrary to published records, A. b. rubrirostris has been present in mainland Ecuador at least since the early 20th century, although probably in low numbers. During the 20th century, the...

... 26 June 2015, a female A. bahamensis was observed with eight ducklings swimming in 133 the southern pool of the Cumbaya reservoir (Fig. 2). Ducklings were still covered by down 134 but transitioning to juvenile plumage: face grayish-cream, superciliary band grayish-cream 135 and faint, dark line from eye to nape diffuse, foreneck dark gray, cheeks whitish, lines on 136 sides of back whitish and soft, ventral surfaces whitish with faint lateral stripes, bill bluish 137 ...

Single-probe near-infrared spectroscopy (NIRS) usually uses different spectral information for modelling, but there are few reports about its influence on model performance. Based on sized-adaptive online NIRS information and the 2D conventional neural network (CNN), minced samples of pure mutton, pork, duck, and adulterated mutton with pork/duck w...
To explore the effect of MYOZ1 in the muscle growth and development of meat ducks, MYOZ1 single-nucleotide polymorphism loci were screened at the DNA level in the meat duck population with highest and lowest feed conversion rates. The expression of MYOZ1 was detected using reverse-transcription quantitative polymerase chain reaction. The protein ex...
Recently, Harpadon nehereus (Bombay duck) has become one of the most important economic fishes in the East China Sea. Understanding the population growth and fishery exploited status of H. nehereus is of great significance for improving its biological knowledge and exploring the driving factors of population expansion in the East China Sea. Based o...
The present paper described the pattern and sustainability of livestock diversification in 30 districts of Odisha. Secondary data of livestock census were used in computing Simpson diversification index and composite index. The study reveals that during the censual period 1992 to 2012, the individual pattern of crossbred cattle and goat has been de...

... The Notes section has three papers with varied information. A small but important review on the White-cheeked Pintail Anas bahamensis in the High Andes finds that, contrary to what current literature supposes, the species has been common and increasing in distribution in Ecuador since the 20 th century (Cisneros-Heredia et al. 2022). The authors also provide the first detailed description of plumage transitions as juveniles of the species grow to become adults. ...
