“…Seabirds face many challenges including habitat loss, introduction of predators, collision with man-made structures, light pollution, toxins, change in prey availability, and poisoning (Millenium Ecosystem Assessment 2005, Hebshi et al 2008, Duffy 2010, Griesemer and Holmes 2011, Loss et al 2012, Wiley et al 2013). These challenges have typically led to severe population declines and in some cases extinctions, resulting in reduced nutrient inputs to the terrestrial habitats that seabirds traditionally occupied.…”

“…Nearly a half million tons of guano were extracted from Laysan Island alone (Shallenberger 2006). Between 1842 and 1915, over 1.3 million seabirds were harvested at Laysan, Lisianski and Midway (Spennemann 1998;Shallenberger 2006;Duffy 2010). Additionally, rabbits which had been introduced to Laysan in 1903 were decimating the native vegetation and bird fauna (Butler and Unsinger 1963;Lamoureux 1963;Ely and Clapp 1973;Olson 1996;Athens et al, 2007;Duffy 2010).…”

This in turn wreaked havoc on the native fauna and flora of Laysan, and by 1923 only four of the originally documented 27 species of plants, as well as only three of five land bird species, remained (Butler and Unsinger 1963;Lamoureux 1963;Ely and Clapp 1973;Clapp et al, 1996;Athens et al, 2007;Duffy 2010).…”

“…Kauai residents are encouraged to assist fallout birds by delivering them to aid stations for a veterinary examination, after which they are released if deemed to be in physical condition appropriate for fledging (Reed et al 1985, Telfer et al 1987, Rauzon 1991. Many individuals are located, banded, and released each season, but their fate after release is unknown (Duffy 2010).…”

Modeling artificial light viewed by fledgling seabirds

Abstract. Artificial light is increasing in coverage across the surface of our planet, impacting the behavioral ecology of many organisms. Attraction to sources of artificial light is a significant threat to certain fledgling shearwaters, petrels (Procellariidae), and storm-petrels (Hydrobatidae) on their first nocturnal flights to the sea. Disorientation by light can cause these birds to crash into vegetation or manmade structures, potentially resulting in death from physical injury, starvation, dehydration, predation by introduced predators, or collisions with vehicles. We developed a GIS-based method to model the intensity of artificial light that fledgling procellariids and hydrobatids could view en route to the ocean (to estimate the degree of threat that artificial light poses to these birds) and present two models for the island of Kauai as examples. These models are particularly relevant to the federally threatened Newell's Shearwater, or`A`o (Puffinus newelli ), of which .30,000 fledglings have been collected in response to disorientation by lights on Kauai during the past 30 years. Our models suggest that there are few to no portions of Kauai from which young birds could fledge and not view light on their post-natal nocturnal flights, which is concerning given evidence of a Newell's Shearwater population decline. In future work using this technique, night light intensity layers could be altered to model the effects of modified coastal light conditions on known and potential procellariid and hydrobatid breeding locations. Furthermore, certain methods presented herein may be applicable to other seabirds and additional taxa in which attraction to anthropogenic light poses a serious threat, including migratory passerines and hatchling marine turtles. Components of this modeling approach could potentially be used to spatially estimate effects of other point-source threats to ecological systems, including sound and air pollution.
