Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
USDA Wildlife Services: Staff Publications
Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most vulnerable, and control methods employed. Bird problems varied by island, but cardinals ( …
A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark
A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark
USDA Wildlife Services: Staff Publications
Cattle are the main reservoir for human infection by pathogenic Escherichia coli and Salmonello enterico. To prevent entry of these foodborne pathogens into the human food chain, management factors at the farm level must be identified and controlled. External sources of contamination, such as birds, should be considered as potential sources of transmission over long distances. In this review, we focus on the epidemiology of infection by E. coli and S. enterica and the consequences of birds acting as disseminators of these pathogens at dairy farms in terms of cattle health and the subsequent effects on human health.
Invasive Predators: A Synthesis Of The Past, Present, And Future, William C. Pitt, Gary W. Witmer
Invasive Predators: A Synthesis Of The Past, Present, And Future, William C. Pitt, Gary W. Witmer
USDA Wildlife Services: Staff Publications
Invasive predators have had devastating effects on species around the world and their effects are increasing. Successful invasive predators typically have a high reproductive rate, short generation times, a generalized diet, and are small or secretive. However, the probability of a successful invasion is also dependent on the qualities of the ecosystem invaded. Ecosystems with a limited assemblage of native species are the most susceptible to invasion provided that habitat and climate are favorable. In addition, the number of invasion opportunities for a species increases the likelihood that the species will successfully establish. The list of routes of entry or …

Use Of Alpha-Chloralose By Usda Wildlife Services To Immobilize Birds, Jeanette R. O'Hare, John D. Eisemann, Kathleen A. Fagerstone, Lawanna L. Koch, Thomas W. Seamans
Use Of Alpha-Chloralose By Usda Wildlife Services To Immobilize Birds, Jeanette R. O'Hare, John D. Eisemann, Kathleen A. Fagerstone, Lawanna L. Koch, Thomas W. Seamans
USDA Wildlife Services: Staff Publications
In 1992, the U. S. Food and Drug Administration (FDA) opened an Investigational New Animal Drug (INAD) file for the avian immobilizing agent, alpha-chloralose (AC) for the United States Department of Agriculture, Animal and Plant Health Inspection Service (APHIS). Currently, this INAD authorizes trained Wildlife Services (WS) personnel to use AC to immobilize and live-capture nuisance waterfowl (Anatidae spp.), American coots (Fulica americana), pigeons (Columba livia), common ravens (Corvus corax) and sandhill cranes (Grus canadensis). The use of AC has proven to be a valuable tool for WS and the number …
