DNA barcoding, an inventory of DNA sequences from a standardized genomic region, provides a bio-barcode for identifying and discovering species. Several recent studies suggest that the sequence diversity in a 648 bp region of the mitochondrial gene for cytochrome c oxidase I (COI) might serve as a DNA barcode for identifying animal species such as North American birds, insects and fishes. The present study tested the effectiveness of a COI barcode in discriminating Korean bird species. We determined the 5′ terminus of the COI barcode for 92 species of Korean birds and found that species identification was unambiguous; the genetic differences between closely related species were, on average, 25 times higher than the differences within species. We identified only one misidentified species out of 239 specimens in a genetic resource bank, so confirming the accuracy of species identification in the banking system. We also identified two potential composite species, calling for further investigation using more samples. The finding of large COI sequence differences between species confirms the effectiveness of COI barcodes for identifying Korean bird species. To bring greater reliability to the identification of species, increased intra- and interspecies sampling, as well as supplementation of the mitochondrial barcodes with nuclear ones, is needed. ; This study was supported by the Korea Science and Engineering Foundation (KOSEF) grant funded by the Korea government (MOST) (No. M10508040002-06N0804- 00210), the Brain Korea 21 Program for Veterinary Science funded by the Ministry of Education, and the Korea National Research Resource Collection Program funded by the Korea Science and Engineering Foundation. We express our appreciation to Mr. Tae Wook Kang for assistance with data analysis and special thanks to Tae Young Choi, Dong Gi Choi, and Chun Gweon Choi for donating road-killed samples collected for the Eco-technopia 21 Project, the Korean Government's R&D Program on environmental technology develop- ment. The authors also thank the Korean Association for Bird Protection in Cheorwon, Korea and the Wildlife Rescue Center in Suncheon for samples.

AbstractThis essay frames the 2020 Central Park bird-watching incident, in which a white financial analyst called police on a Black bird-watcher, in the context of histories of settler colonialism, extraction, and white supremacy. Situating ornithology as a white way of seeing, it considers the extermination and extinction of birds in terms of fugitivity, necrography, and eugenics, engaging the work of Audubon and the collection and display of birds at the American Museum of Natural History. It closes with a reflection on the Assembly of Birds in Aotearoa New Zealand, as depicted by painter Bill Hammond, and the work of decolonizing extinction.

In the mid-1960s, State officials of Virginia recognized an increasing bird damage problem, yet no legislation existed that allowed any state agency the authority to initiate a nuisance bird control program. In 1968, with bird damage estimated at 25 million dollars, the Virginia General Assembly passed the Nuisance Bird Law. This law provided the basic legislation for the Virginia Department of Agriculture and Commerce (VDAC) to allow its personnel to investigate complaints, conduct surveys, and initiate bird control programs when necessary. Administration of the law is by the Plant Pest Control Section of the VDAC along with a cooperative agreement with the U.S. Fish and Wildlife Service and the Virginia Cooperative Extension Service. This paper is intended to explain how the VDAC, now the Virginia Department of Agriculture and Consumer Services (VDACS), conducts its program, the problem bird species encountered, the control techniques employed, the unique bird problems in the State, and the acceptance of the program by the public.

There is a risk that birds may be poisoned during feral pig poisoning programs. Experiments in a field
plot adjoining an urban area were conducted to assess the acceptance of dyed wheat, maize and sorghum
by free-ranging birds. All colouring agents depressed the acceptance of grain by birds. This suggests that
dyeing feral pig baits should reduce the hazard of bird poisonings. Observations of birds on feed trays
were of limited value in predicting intake.

Article discussing length of hunting seasons for game birds, including ducks and band-tailed pigeons. Submitted to the Oregon Journal newspaper.

Since its release for Apple's iPhone in 2009, Angry Birds has been one of the most successful video games in history. Although Angry Birds seemed to be an overnight success, the game was actually the result of years of struggle by Rovio Entertainment, the Finnish company that created it. The company's founder, Niklas Hed, his cousin Mikael Hed, and Peter Vesterbacka have established not just a profitable video game but a cultural phenomenon. In this thrilling narrative, readers examine the challenges and triumphs of building a company while keeping the spirit of fun behind the development of new products
