“…fewer nocturnally migrating passerines were affected by shorter wavelengths, i.e. green and blue light, relative to white light or light with longer wavelengths; Poot et al 2008). Given the results of our study and previous fallout research, studies further investigating the effects of light wavelength and/or intensity on fallout may be an important next step in the conservation of these birds.…”

Attraction of fledgling shearwaters, petrels, and storm-petrels to artificial light has been documented for decades on islands around the world and is considered a significant threat to many species. Although large numbers of downed birds have been observed after being disoriented by light, several important elements of this 'fallout' phenomenon are unknown, including the locations along the path from nest to ocean at which attraction and/or disorientation occurs and whether fledglings can be attracted back to land after reaching the ocean in numbers large enough to contribute significantly to fallout. To investigate these questions, we compared observed Newell's shearwater Puffinus newelli fallout records (from 1998 to 2009) on Kauai, USA, with expected numbers generated from several hypothetical models containing basic assumptions related to fledgling movement and attraction to light. Based on our results, the spatial pattern of observed fallout is consistent with the amount of light that fledglings may view along their first flights to and beyond the coastline. This suggests that even fledglings from dark regions of the island may not be safe because they may view light after reaching the ocean and still be susceptible to attraction. These findings support recent modeling efforts predicting that most birds fledging from Kauai are likely exposed to at least some anthropogenic light. As nocturnal use of light by humans is unlikely to be eliminated, research on the types of artificial light that are both useful to humans and safe for seabirds may be crucial for the conservation of these important marine animals.

Many succumbed to exhaustion and perished without completing their migration.…”

We express our appreciation to the Cities of Toronto, New York, and Chicago and the State of Minnesota, whose guidelines and standards provided a basis for these. Thanks also to the following people for their work to make the built environment safer for the winged animals who enrich our world, and with whom we share our City: This document is based in part on guidelines published by: New York City Audubon Society, Inc., May 2007; the Audubon Minnesota, May 2010; and an unpublished draft of the National Guidelines by the American Bird Conservancy.

RECOmmENDED ACTIONS AND BIRD-SAFE STEwARDSHIP 33Public Pigeons and sparrows are readily visible in San Francisco. These ubiquitous city birds are not shy about sharing our urban spaces. But the casual observer may be shocked to learn that our City's birds are much more diverse. There are about 400 species of birds in San Francisco; remarkably, this is nearly half the species in all North America (Kay 2009). For those who look, the shyer species are just around the corner. This is due in part to the diverse habitats of the Bay Area and its position on the coastal migration path, the Pacific Flyway. Some birds are well-adapted to urban life, and they may remain here as year-round "residents." Others are migratory, passing through the City southward in autumn en route to their winter feeding grounds, then returning northward in spring to establish territories in summer breeding grounds.There are special problems posed for birds living in or flying through cities. Over 30 years of research has documented that buildings and windows are the top killer of wild birds in North America (Banks 1979;Ogden 1996;Hager et al. 2008;Klem 2009;Gelb and Delacretaz 2009). Structure collision fatalities may account for between 100 million and 1 billion birds killed annually in North America (United States Fish and Wildlife Service 2002;Klem 2009).

“…ALAN can affect several behaviors of wild animals, from orientation and navigation during dispersal and migration (Rich and Longcore, 2006;Poot et al, 2008), to daily and seasonal rhythms in behavior Robert et al, 2015;Dominoni et al, 2016), to more subtle physiological effects on stress levels, body mass and immune responses (Bedrosian et al, 2011;Ouyang et al, 2015;Raap et al, 2016a). Effects on circadian rhythms of behavior and physiology are particularly evident in a range of species, from insects to mammals (Swaddle et al, 2015).…”

Artificial Light at Night Reduces Daily Energy Expenditure in Breeding Great Tits (Parus major)

et al. 2017

The ecological impact of artificial light at night (ALAN) is an increasingly recognized process that accompanies expanding urbanization. Yet, we have limited knowledge on the impact of ALAN on wild species, and on the potential to mitigate any negative effects by using different light sources and colors. In birds, effects of ALAN on activity levels are reported for several species and, hence, their daily energy expenditure (DEE) may be affected. DEE is a potent mediator of life-history trade-offs and fitness and thus an important aspect to consider when examining the potential long-term ecological effects of ALAN. Previous work has suggested that birds exposed to ALAN show higher levels of provisioning and nocturnal activity, suggesting that white ALAN increases DEE. Other factors regulating DEE, such as provisioning behavior and food availability, might also respond to ALAN and thus indirectly affect DEE. We tested the hypothesis that ALAN increases DEE using an experimental setup where four previously unlit transects were illuminated with either white, green, or red LED light, or left dark as a control treatment. This setup was replicated in eight locations across the Netherlands. We measured DEE of our focal species, the great tit (Parus major), using a novel doubly labeled water technique that uses breath rather than blood samples. Contrary to our expectations, birds feeding their offspring under white and green ALAN showed lower DEE compared to birds in the control dark treatment. Differences in chick provisioning activity did not explain this result, as neither visit rates nor daily activity timing was affected by light treatment. However, food availability under white and green light was much higher compared to red light and the dark control. This difference strongly suggests that the lower DEE under white and green ALAN sites is a consequence of higher food availability in these treatments. This result shows that there can be positive, indirect effects of ALAN for breeding song birds which may balance against the negative direct effects shown in previous studies.
