Rollo Howard Beck (1870-1950) was an American ornithologist and naturalist known for his extensive explorations and research in the Pacific islands and his contributions to the study of birds. He was born on August 21, 1870, in California, USA.

Key Contributions and Achievements:

1. Pacific Island Explorations: Beck conducted numerous scientific expeditions to various islands in the Pacific, including Hawaii, Fiji, Samoa, and the Solomon Islands. He made significant contributions to the understanding of the avifauna (bird life) of these remote and often isolated islands.
2. Documentation of Birds: During his expeditions, Beck collected and documented thousands of bird specimens, including many previously unknown species. His work greatly expanded the knowledge of Pacific island bird diversity.
3. Hawaiian Birds: Beck’s research in Hawaii was particularly notable. He extensively studied the native avian species of the islands, including the critically endangered Hawaiian crow, or ‘Alalā, and the Hawaiian honeycreepers.
4. Published Works: Beck published various scientific papers and articles on the birds and other fauna of the Pacific islands. His research findings were widely recognized and contributed to the knowledge of Pacific island biodiversity.
5. Legacy: Beck’s contributions to Pacific island ornithology significantly advanced the understanding of the region’s bird life. His extensive collections of bird specimens and documentation continue to be valuable resources for researchers studying the avifauna of the Pacific.
6. Name in Ornithology: The names of several bird species have been dedicated to Rollo H. Beck in recognition of his contributions. For example, the “Beck’s Petrel” (Pseudobulweria becki) is named after him.

Rollo H. Beck’s expeditions and research in the Pacific islands have left a lasting impact on the field of ornithology, especially concerning the avian fauna of the region. His dedication to scientific exploration and documentation of birds in remote areas has contributed significantly to our understanding of the biodiversity of the Pacific islands.
