The Great Blue Heron (Ardea herodias) and Roseate Spoonbill (Platalea ajaja) are long-legged wading birds that can forage throughout a 24-hour cycle. Nocturnal foraging enables these species to take advantage of optimal foraging conditions and reduced competition. This study aims to investigate how environmental factors influence the nocturnal foraging behavior of these species. To monitor foraging activity, we deployed 17-18 infrared cameras from dusk until dawn from 4 October 2023 to 24 July 24 2024, covering two sampling periods across different habitats within Fort De Soto County Park, a barrier island complex in Tampa Bay, Florida. We compared the frequency …

Abiotic Factors Influencing Anuran Occupation Of Neotropical Brazilian Caves, Vinícius F. Sperandei, Willian Vaz-Silva, Tejerina-Garro L. Francisco
International Journal of Speleology
Despite increasing research on the Neotropical underground environment, anurans remain poorly understood in this habitat. It was analyzed scientific literature records of anurans in Brazilian natural caves and performed a redundancy analysis (RDA) to identify the environmental, taxonomic, geographic, geological and land-use variables that influence their cave occupancy. It was examined a total of 247 literature records, encompassing 83 species/morphospecies, which revealed distinct cave-dwelling tendencies. Some anuran species occupy caves at altitudes between 5 to 21 meters above sea level (m asl), in areas characterized by rocky outcrops and grassland. Others are associated with caves surrounded by forest, savanna, pasture …

Monteverde Institute: Tropical Ecology and Conservation
Rural and semi-rural regions around the globe often struggle with inadequate wastewater treatment infrastructure, thereby negatively impacting the public and environmental health of the region. Due to its rural nature and current infrastructure, the Monteverde Zone (MVZ) in Costa Rica lacks a centralized wastewater system, with many homes relying on septic tanks for wastewater treatment. To prevent overloaded flows to septic tanks, greywater from kitchens, laundry, showers, and sinks is often discharged separately to the environment with no treatment. This pollutes the surrounding water bodies and streets with pathogens, soap, excess nutrients, as well as fats, oils, and grease (FOG). …

Bayes In The Brain: A Review Of Everything Is Predictable: How Bayesian Statistics Explain Our World, (2024) By Tom Chivers., Michael T. Catalano
Numeracy
Tom Chivers’ Everything is Predictable: How Bayesian Statistics Explain Our World, is an interesting and wide-ranging narrative on Bayesian thinking, its history, and its applicability to both our everyday lives and the pursuit of scientific truth. Although appropriate for the non-expert, afficionados and teachers of quantitative literacy should find the plethora of examples, links to psychology as it applies to how people reason about probabilities, and even Chivers’ philosophical musings informative and thought-provoking.

Where Are The Criminologists?: The Persistent Absence Of The Field In Genocide Research, Grace Allbaugh, Susan A. Woollen, Jacqueline L. Schneider, Joanne Savage
Genocide Studies and Prevention: An International Journal
The rallying cry of “Never Again” was heard worldwide after the Nazis’ annihilation of Jews and other victims were discovered after WWII. The global community promised that the crime of genocide would be prevented and signatory parties of the United Nations Convention on the Prevention and Punishment of Genocide (December 9, 1948) would do everything in their power to prevent another Holocaust from occurring. Unfortunately the “crime of all crimes” remains an almost permanent fixture in international news while signatory parties remain reluctant to call the ongoing conditions genocide. The field of genocide studies is built upon an interdisciplinary field …

First Ground Visit To The Emperor Penguin Aptenodytes Forsteri Colony At Jason Peninsula, Larsen C Ice Shelf, Weddell Sea, Antarctica, Jonathan Zaccaria
Marine Ornithology
The growth of ecotourism leads tour operators to develop means of exploration that facilitate access to remote and difficult-to-reach areas. For instance, new ice-class expedition ships can now bring visitors to isolated places in Antarctica that have never before been visited. In November 2021, a first ground visit was made to the Emperor Penguin Aptenodytes forsteri colony at the Jason Peninsula. The result is the first census of the population that has been conducted in situ. This example illustrates that reaching extremely isolated places through ecotourism is an opportunity to develop citizen science and collect useful data.

Rapid Increase In Size Of Wedge-Tailed Shearwater Ardenna Pacifica Colony Following Rat Eradication, Danielle Z. Keys, Robert W. Bullock, Clare Keating, Pierre A. Pistorius
Marine Ornithology
Invasive mammalian predators have devastating effects on seabird nesting colonies. A census was conducted on breeding Wedge-tailed Shearwaters Ardenna pacifica in 2016 and 2021 on D’Arros Island, Seychelles, which has been rat-free since 2003. Results were compared with an earlier population estimate to assess population growth following the rat eradication. Compared to counts in 2009, we estimated a 10-fold increase in breeding population size, with 2768 (95% confidence interval (CI) 2424–3112) and 2406 (95% CI 2143–2667) breeding pairs in 2016 and 2021, respectively. While the estimated increase is partly attributable to differences in the timing of the conducted census between …

Establishment Of An Incipient Newell’S Shearwater Puffinus Newelli Colony On Maui, Gregory Spencer, Mitchell Craig, Brad Yuen, David Ainley
Marine Ornithology
We report the development of a colony of threatened Newell’s Shearwater Puffinus newelli (NESH) at Makamaka‘ole, West Maui, USA, a successful first undertaking in the Hawaiian Islands. Efforts involved the construction of two predator-proof fenced areas, removal/control of predators, placement of nest boxes, and social attraction using recorded calls and decoys. Initially, one of the management areas was intended for Hawaiian Petrel Pterodroma sandwichensis (HAPE) and the other for NESH. Exclosures were completed and mammalian predators were removed in 2013, and social attraction began in 2014. Both species almost immediately began flyovers to inspect speakers and by 2015, they had …
A 31-Year Time Series Of At-Sea Counts Shows A Non-Significant Decline Of Marbled Murrelets At Laskeek Bay, Haida Gwaii, 1990–2020, Vivian Pattison, Douglas F. Bertram, Sonya A. Pastran, Anthony J. Gaston, Rian D. Dickson, Mark C. Drever

Marine Ornithology
The Marbled Murrelet Brachyramphus marmoratus breeds and overwinters along the coast of British Columbia, Canada, and is listed as Threatened under the Canadian Species at Risk Act. Understanding population trends for this seabird species is important for management and recovery, yet long-term time-series data for Marbled Murrelet abundance are rare. We update trends and annual fluctuations of Marbled Murrelet numbers derived from at-sea counts in Laskeek Bay, Haida Gwaii, on the north coast of British Columbia, 1990–2020. We found a non-significant negative trend (−1.55% per year). Counts varied seasonally and peaked in early June; counts also varied with distance from …
Predator Disturbance Contributed To Common Murre Uria Aalge Breeding Failures In Cook Inlet, Alaska Following The 2014–2016 Pacific Marine Heatwave, Caitlin E. Marsteller, Mayumi L. Arimitsu, Sarah K. Schoen, Samuel B. Stark, John F. Piatt
Predator Disturbance Contributed To Common Murre Uria Aalge Breeding Failures In Cook Inlet, Alaska Following The 2014–2016 Pacific Marine Heatwave, Caitlin E. Marsteller, Mayumi L. Arimitsu, Sarah K. Schoen, Samuel B. Stark, John F. Piatt
Marine Ornithology
The 2014–2016 Pacific marine heatwave caused unprecedented die-offs and multi-year reproductive failures for Common Murres Uria aalge along the west coast of North America. Lingering impacts, such as declines in colony attendance and productivity, have persisted at some colonies following the heatwave and are attributed largely to changes in prey availability and quality. Here, we present evidence of an additional, top-down mechanism contributing to Common Murre breeding failures on Gull Island (Alaska): disturbance of nesting birds by aerial predators and associated egg depredation. We collected time-lapse images over five murre breeding seasons (2016–2020) on Gull Island to document the frequency, …

Marine Ornithology
In 2022, highly pathogenic avian influenza (HPAI) virus resulted in mass mortality throughout seabird colonies in the North Atlantic Ocean. While mortalities and transmission of the virus are being documented, other effects are less understood. We documented nest abandonment and unprecedented reproductive failure by Northern Gannets Morus bassanus at Cape St. Mary’s, Newfoundland and Labrador, Canada, the species’ southernmost colony. Reproductive success in 2022 was the lowest on record at 17%, which was likely a result of adults abandoning the nest and succumbing to avian influenza virus (AIV) infection. Following the AIV outbreak at Cape St. Mary’s, we also documented …

Melanistic Razorbill Alca Torda At Machias Seal Island, New Brunswick, Canada, Heather L. Major, Tabatha L. Cormier, Antony W. Diamond
Marine Ornithology
Aberrant colouration in birds is relatively common but melanism occurs infrequently. We report an observation of a melanistic Razorbill Alca torda attending the nesting colony at Machias Seal Island, Bay of Fundy in 2022 and 2023. This is the third reported occurrence of a melanistic Razorbill and the first in over 100 years.

Finding Colonies Of Black-Headed Gulls Chroicocephalus Ridibundus Using Google Earth, Roberto G. Valle, Alejandro Corregidor-Castro, Francesco Scarton
Marine Ornithology
We explore the possibility of identifying Black-headed Gull Chroicocephalus ridibundus colonies in the saltmarshes of the Lagoon of Venice, Italy, using Google Earth satellite images. One reproductive season was considered (June 2017), based on the images available on Google Earth. This species builds nests clustered around tidal pools and tidal creeks, providing a dark background to reveal the white gulls. Images of the southern part of the lagoon (excluding fish farms) were analyzed by dividing it into sectors (n = 403) using the Google Earth grid at an elevation of 100 m above ground level. The results of the satellite …
Notes On A Plover Briefly Incubating An Oystercatcher Nest In Patagonia, José O. Valdebenito
Notes On A Plover Briefly Incubating An Oystercatcher Nest In Patagonia, José O. Valdebenito
Marine Ornithology
A breeding female Two-banded Plover Charadrius falklandicus was observed incubating the eggs of a Magellanic Oystercatcher Haematopus leucopodus while the nest was unattended by the oystercatcher. The behaviour was likely triggered by the plover’s nest becoming momentarily inaccessible, and so, being in incubation mode, the bird responded by incubating the nearest nest available. This is the first report of such behaviour while the oystercatcher was nearby, and the plover nest was still active and in sight.
Marbled Murrelet Brachyramphus Marmoratus Use Of A Freshwater Lake On Vancouver Island, British Columbia, 2018–2023, Daryl S. Henderson, Spencer G. Sealy
Marbled Murrelet Brachyramphus Marmoratus Use Of A Freshwater Lake On Vancouver Island, British Columbia, 2018–2023, Daryl S. Henderson, Spencer G. Sealy
Marine Ornithology
Marbled Murrelets Brachyramphus marmoratus are small seabirds widely distributed in nearshore waters on the west coast of North America, from Alaska to central California. A 1986 review of anecdotal records revealed that Marbled Murrelets use coastal freshwater lakes during the breeding season, possibly to forage, and in winter, possibly while prospecting for nest sites in old-growth forest. Our weekly surveys and observations on Sproat Lake (central Vancouver Island, British Columbia, Canada) from November 2018 to March 2023, confirmed year round use by murrelets, with absences during the prealternate molt (beginning mid-March) and the prebasic molt (August and September), when the …

Marine Ornithology
Species population estimates are a fundamental component of conservation planning, but there are deficiencies in reliable data for many seabirds. The Pink-footed Shearwater Ardenna creatopus is a seabird that breeds on three islands worldwide, with the largest population on Isla Mocha, Chile. We aimed to update the breeding population estimate of Pink-footed Shearwaters on Isla Mocha, comparing results from design- and model-based estimation methods. We counted shearwater burrows in 220 randomly generated five-meter-radius plots across pre-defined strata on Isla Mocha. We estimated total number of burrows using area-based extrapolation (design-based method), and separately using a model predicting burrow density based …
Status And Occurrence Of Wedge-Tailed Shearwater Ardenna Pacifica In Waters Of The Northwestern Coast Of South America, Manuel Marín
Status And Occurrence Of Wedge-Tailed Shearwater Ardenna Pacifica In Waters Of The Northwestern Coast Of South America, Manuel Marín
Marine Ornithology
This study examines the distribution of Wedge-tailed Shearwater Ardenna pacifica along the northwest coast of South America. The species is well known in tropical waters distant from the coast, but it also appears to be a regular visitor to shelf-break waters off Colombia and northern Ecuador; there is no evidence indicating a similar presence within the exclusive economic zone (EEZ) of Peru, where waters are colder. About 50% of Wedge-tailed Shearwater sightings are associated with dolphins and/or large fish. More than 90% of the nearshore South American records are of pale-phase individuals.

Tracked Gulls Help Identify Potential Zones Of Interaction Between Whales And Shipping Traffic, Megan A. Cimino, Heather Welch, Jarrod A. Santora, David Kroodsma, Elliott L. Hazen, Steven J. Bograd, Pete Warzybok, Jaime Jahncke, Scott A. Shaffer
Marine Ornithology
Seabird-vessel interactions are often studied through the lens of fisheries bycatch, but seabirds encounter many watercraft types. Western Gulls Larus occidentalis breeding on the Farallon Islands (California, USA) have a foraging domain that encompasses both shipping lanes and productive fishing grounds, resulting in ample opportunities for vessel encounters. Previous research showed that these Western Gulls can serve as ecosystem indicators because their foraging behavior is linked to ocean prey conditions, and because their foraging grounds overlap with that of Humpback Whales Megaptera novaeangliae, which can make prey accessible. Because ship strikes and entanglement in fishing gear are concerns for whales …

Marine Ornithology
We report predation by an Arctic Fox Alopex lagopus on two seabird species, Atlantic Puffins Fratercula arctica and Leach’s Storm Petrels Hydrobates leucorhous, nesting on Bakeapple Island, Little Fogo Islands, Newfoundland, Canada. This event took place in 2022, when a whole-island inspection revealed that fox, facilitated by over-ice invasion, killed at least 139 adult storm petrels and 8 puffin chicks. The fox also dug out 83 storm petrel and 4 puffin burrows. Breeding by seabirds on the island, which harbours some of the northernmost colonies in Newfoundland, was also largely disrupted; we documented extremely low egg and chick production values …

Intra-Annual Shifts In Atlantic Puffin Fratercula Arctica Depredation And Kleptoparasitism By Larus Gulls At A Multi-Species Seabird Colony, Gibson M. Rieger, Gail K. Davoren
Marine Ornithology
Great Black-backed Gulls Larus marinus and American Herring Gulls L. argentatus smithsonianus are considered dietary generalists at the population level: they consume a variety of prey types, including the adults and offspring of other seabirds, and they shift among prey types as availability varies. Atlantic Puffin Fratercula arctica adults, eggs, and chicks are often the target of depredation, and adults are also susceptible to kleptoparasitic attacks by large gulls during their summer breeding season in coastal Newfoundland, Canada. We investigated the depredation and kleptoparasitism of puffins by large gulls during July–August 2021/22 at a multi-species breeding colony on the northeast …
