Abstract:
Understudied, widespread species may harbour underappreciated variation in morphology. Museum specimens represent a rich source of morphometric data, and for many species this information is untapped. Here we present a dataset derived from standardised photography of museum specimens of Jungle Crows (Corvus macrorhynchos), a widespread Asian Corvid. We photographed 1105 crows, for which 1069 we managed to collect measurements of hard tissue (i.e., bill characteristics and tarsus length). We combined these measurements with museum-curated data on the locality of the specimens, resulting in a geotagged dataset of Jungle Crow morphology. The measured crows originated from across their distribution, representing the most comprehensive morphometric dataset for Corvus macrorhynchos to date. The dataset is a valuable resource for exploring the driving forces behind morphological variation in Corvus macrorhynchos, as well as a foundation for intraspecific comparison of proposed subspecies and interspecific comparisons of other bird species.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
