Hi there. I have been birding most of my life and am currently a grad student working on a bird migration study. "A bird does not sing because it has an answer. It sings because it has a song."

Native forest birds in Hawaii in unprecedented trouble
Native birds at Hakalau Forest National Wildlife Refuge are in unprecedented trouble, according to a paper recently published in the journal PLoS ONE…..In the paper, Freed and Cann report that birds are now so food-deprived that they take up to twice as long replace their feathers, an annual process known as molt. The authors confirmed the hypothesis that Japanese white-eye (Zosterops japonicus) birds are effectively competing with most species of native birds.
The House Sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. One of 27 species in the genus Passer, the House Sparrow occurs naturally in most of Europe, the Mediterranean region, and much of Asia. Its intentional or accidental introductions to many regions, including parts of Australia, Africa, and the Americas, make it the most widely distributed wild bird. The House Sparrow is strongly associated with human habitations, and can live in urban or rural settings.
