TL;DR: The results support that Estrildids are a monophyletic group with polytomies that may have started evolving by Middle Miocene Epoch (about 16, 5 million years ago), and suggest that the whole Estrialdids radiation might have originated around India.
Abstract: Estrildid finches are distributed throughout Africa, South Asia, Australia and neighbouring islands in the Indian and Pacific Oceans. Some specific phylogenetic and systematic debated questions have been clarified in the present study by mitochondrial cytochrome b DNA sequencing of 61 species of Estrildids and subsequent analyses of results by both Bayesian Inference and Maximum Likelihood methodologies. Our results support that Estrildids are a monophyletic group with polytomies that may have started evolving by Middle Miocene Epoch (about 16, 5 million years ago). This proposed timing is coincidental with the Fringillinae finches' radiation starting time and also with the biggest Hymalayan and Ti- betan Plateau uplift, triggered by the Indian tectonic plate strongest collision; this established present day southern Asia monsoon regime and other drastic climatic changes, like a dryer weather in Tibetan Plateau and China deserts. The Estrildid finches form a monophyletic group which includes several polytomies and comprises African, Asian and Austra- lian birds. The most ancient evolutive group comprises African (African silverbill), Asian (Indian silverbill) and Austra- lian (diamond firetail); this suggests that the whole Estrildids radiation might have originated around India.More Estrildid species will be studied in order to further establish this group phylogeography. In addition, monophyletic radiations in- clude species from different Continents. Finally, Ploceinae Genus Quelea finches is a group separate and basal from Estrildini and Viduini species in our dendrograms.

TL;DR: Investigation of the diversity and status of avian species of Curzon Hall premises, University of Dhaka, Bangladesh found that species richness was in the highest peak in the late winter and early spring and comparatively less in other seasons.
Abstract: In order to estimate the diversity and status of avian species of Curzon Hall premises, University of Dhaka, Bangladesh, a study was conducted from January 2012 to January 2014. A total of 50 species of birds belonging to 30 families under 12 orders were recorded of which, regarding the relative abundance, 29 were common and 21 were uncommon. Twenty five species, in total, were identified as breeding residents, 13 as non-breeding residents and 12 as migrants. Of all the species identified from the study site, one was Critically Endangered (Alexandrine Parakeet Psittacula eupatria ) and six were new for the campus (Taiga Flycatcher Ficedula albicilla, Indian Silverbill Lonchura malabarica, Ashy Drongo Dicrurus leucophaeus, Eurasian Wryneck Jynx torquilla, Pied Cuckoo Clamator jacobinus, Lesser Whistling Duck Dendrocygna javanica ). Passerines were the dominating group as represented by 27 species from 16 different families. Species richness was in the highest peak in the late winter and early spring and comparatively less in other seasons.

TL;DR: The two silverbills show a general similarity in appearance and behaviour but differ in plumage pattern and colour, and are regarded as two species, Lonchura cantans and L. malabarica.
Abstract: Summary
The taxonomic status of the African and Indian Silverbills, cantans and malabarica, was examined. The characters used to isolate these birds in a separate genus, Euodice, are not generically valid, and the birds agree in morphology and behaviour with species of the genus Lonchura. The two silverbills show a general similarity in appearance and behaviour but differ in plumage pattern and colour. The call notes are similar but the songs are distinctly different in form, although they appear to share a common basic pattern. In captivity the two forms show evidence of preferential mating and lack of recognition which suggests that they would maintain their identity if sympatric. On this basis they are regarded as two species, Lonchura cantans and L. malabarica.
