First Record of Long-tailed Skua \u3ci\u3eStercorarius longicaudus\u3c/i\u3e in Terre Adélie (140°1\u27E–66°40\u27S)
No full textOn 17 January 2023, a Long-tailed Skua Stercorarius longicaudus was observed and photographed along the coast of Terre Adélie (67–90°S, 136–142°E). This is the first observation of this species at this locality since seabird monitoring began in 1952, and it is only the second report of this species at latitudes this far south
Diet Assessment and Vulnerability of White-faced Storm Petrel \u3ci\u3ePelagodroma marina\u3c/i\u3e within a Warming Hotspot
No full textShifts in zooplankton communities due to changing ocean climate can affect foraging patterns among planktivorous seabirds. To better understand seabird response to environmental change in Bass Strait, southeast Australia, we investigated the prey species and 16 elements in prey and feathers of the planktivorous White-faced Storm Petrel Pelagodroma marina. The krill Nyctiphanes australis was the most abundant prey species, followed by several species of post-larval fish; otherwise, the species appeared to be a generalist feeder. Element concentrations of feathers were not significantly influenced by dietary composition. Likewise, element concentrations did not significantly differ between major prey species, confirming that the nutritional profile of these species is likely linked to their seawater environment. Given that White faced Storm Petrels in Bass Strait substantially rely on a narrow range of prey species, this may increase their vulnerability to events that change their availability. As coastal krill is highly sensitive to sea surface temperatures (SST), the increases in SST predicted under climate change scenarios may alter the timing and abundance of krill swarms, which in turn may affect planktivores, including White-faced Storm Petrels
Fish Prey of the Peruvian Tern \u3ci\u3eSternula lorata\u3c/i\u3e along the Northern Coast of Chile
No full textScarce information is available on the trophic ecology and feeding habitats of the Peruvian Tern Sternula lorata. We searched 15 Peruvian Tern colonies along the coast of northern Chile during the breeding seasons of 2008 to 2018 to evaluate the tern’s main food source. We collected samples of prey remains found near nests as well as prey items regurgitated by chicks and adults during our visits. We found that the Peruvian Tern is mainly piscivorous, secondarily feeding on some cephalopods and euphausiids. Pacific Saury Scomberesox saurus and Paloma Pompano Trachinotus paitensis were the main prey found near nests, but regurgitated prey was dominated by the Peruvian Anchoveta Engraulis ringens. Fish prey sizes ranged from 36 to 192 mm. These findings expand existing knowledge of the feeding ecology of this endangered seabird during its breeding season
Wire Ingestion by a Red-billed Tropicbird \u3ci\u3ePhaethon aethereus\u3c/i\u3e Chick on San Pedro Mártir Island, Mexico
No full textWe report the ingestion of wire by a Red-billed Tropicbird Phaethon aethereus chick at San Pedro Mártir Island, Gulf of California, Mexico. A scat sample collected from a four- to five-week-old chick contained a copper wire ~5.0 mm in length. Biologging revealed the previous foraging trips by one of the parents, and we ascertained the diet of birds in this colony through a molecular approach. From these data, we suggest why this individual was fed wire
Status of Craveri’s Murrelet \u3ci\u3eSynthliboramphus craveri\u3c/i\u3e in the Midriff Islands, Gulf of California, Mexico
No full textThe Craveri\u27s Murrelet Synthliboramphus craveri is an endangered seabird (family Alcidae) endemic to northwestern Mexico, where it breeds on rocky islands throughout the Gulf of California (GOC). Nesting records are scarce for most of these islands, and much of the available information relies on historical data collected more than 50 years ago. Beginning in 2009 through to 2023, we performed intermittent nest searches on five islands in the Midriff Islands of the GOC. Starting in 2018 on Alcatraz Island and starting in 2022 on San Pedro Mártir Island, we monitored nests to determine average clutch size and hatching success. We also performed nocturnal spotlight surveys around San Esteban Island and San Pedro Mártir to estimate breeding populations. On Alcatraz, we observed breeding behavior from December to April and chicks departing nests as early as January. During 2020-2023, average clutch size on Alcatraz was 1.6 eggs per active nest and average hatching success was 1.02 eggs, with eggs hatching in 68% of active nests. While we observed numerous murrelets in the waters surrounding some islands, we did not find much evidence of nesting on islands with invasive rodents. On San Pedro Mártir, where invasive rodents were exterminated in 2007, we estimated the breeding population to range from 38 pairs in 2022 to 99 in 2023. Future studies are needed to further quantify the breeding population and to better understand the specific impacts of both invasive rodents and variation in ocean climate upon murrelet nesting. Finally, it is important to examine the causes of variation in nesting success rates and phenology over the years to increase the effectiveness of conservation efforts
Absence of Coronavirus in terns in the Western Indian Ocean?
No full textWe investigated coronavirus circulation in three tern species on four islands of the Western Indian Ocean (Bird, Reunion, Europa, Juan de Nova). None of the 2019 samples tested positive by reverse-transcription polymerase chain reaction. We discuss the implications of these findings in terms of host-species range, ecological drivers of virus transmission, and diagnostic tools
Confirmed Record of Red-footed Booby \u3ci\u3eSula sula\u3c/i\u3e from Lakshadweep Sea, Northern Indian Ocean
No full textThe Red-footed Booby Sula sula occurs across tropical and subtropical oceans, nesting on islands and coastal areas. It is identified by its distinctive red feet, long wings, and sharp bill. However, confirmed reports are rare. Here we report, with photographs, the presence of a Red-footed Booby from the Union Territory of Lakshadweep, northern Indian Ocean. This record adds to the collective understanding of the species’ presence and distribution in the region

GNSI Decision Brief: Building Trust in Digital Response: The Role of Chatbots in Cybercrime Prevention Open-Source Tools for Safer Digital Reporting and Public Trust
No full textCybercrime poses a growing global threat, inflicting financial harm on individuals, businesses, and governments. In 2024 alone, the FBI\u27s Internet Crime Complain Center (IC3) received over 800,000 complains, with reported losses exceeding $16.6 billion, a 33 percent increase from the prior year. The damage extends beyond financial loss: cybercrime undermines trust in digital systems and can cause psychological harm. Its anonymous and complex nature makes detection and prosecurtion difficult, creating low-risk, high-reward conditions for offenders.https://digitalcommons.usf.edu/gnsi_decision_briefs/1029/thumbnail.jp
