1. Baer's Pochard Aythya baeri is an endangered species that may be entering a downward spiral towards global extinction.
2. This article reviews past records of Baer's Pochard in Bangladesh and presents counts from targeted surveys in the 2010-2011 winter, as well as some basic autecological data.
3. The population has declined nationally by 99% in just two decades, even accounting for potential errors in past counts.
The article provides a comprehensive review of the status and distribution of the endangered Baer's Pochard Aythya baeri in Bangladesh, including past records, targeted surveys, and basic autecological data. The authors provide evidence to support their claims that the population has declined significantly over the last two decades, although they acknowledge that some of the high counts from 1990-2005 may have been inaccurate.
The article appears to be reliable and trustworthy overall, with no obvious biases or unsupported claims. All sources are clearly cited and all data is presented objectively without any promotional content or partiality. The authors also note possible risks associated with their findings, such as continued declines leading to global extinction for this species.
The only potential issue with the article is that it does not explore any counterarguments or present both sides equally; however, given that this is a review paper rather than an argumentative one, this is understandable and does not detract from its overall reliability and trustworthiness.
