Digging In! Burrowing Penguins And Surface Predators, Laura X.L. Tan, Kasun B. Ekanayake, Wouter F.D. Van Dongen, Peter Dann, Duncan R. Sutherland, Michael A. Weston Jul 2025

Digging In! Burrowing Penguins And Surface Predators, Laura X.L. Tan, Kasun B. Ekanayake, Wouter F.D. Van Dongen, Peter Dann, Duncan R. Sutherland, Michael A. Weston

Marine Ornithology

A native Australian corvid, Little Raven Corvus mellori, has emerged as a dominant and problematic predator of an ecologically and economically important seabird, the Little Penguin Eudyptula minor. In 2013, ravens successfully preyed upon clutches/broods of the burrow-nesting penguin, especially those in shallower, more accessible burrows. Individual raven size might mediate which ravens attack penguins; smaller ravens may be able to enter burrows more easily; alternatively, larger ravens may be more capable of overcoming penguin parental defence. Here, we consider the predator-prey interactions to assess whether associations with burrow characteristics persisted and examine whether raven size mediated propensity to prey …

At-Sea Movements Of The White Tern Gygis Alba In Waters Off Eastern Australia, Nicholas Carlile, Terence O’Dwyer Jul 2025

At-Sea Movements Of The White Tern Gygis Alba In Waters Off Eastern Australia, Nicholas Carlile, Terence O’Dwyer

Marine Ornithology

We present the first tracked movements of the medium-sized tropical White Tern Gygis alba, using Global Location Sensors (GLS), from a breeding colony on Lord Howe Island, South Pacific, Australia. The tracking period encompassed pre-breeding in 2018 to potential chick provisioning in the following season. Terns remained near Lord Howe Island during breeding, with some pre-egg-laying and post-nest failure trips 1 000 km distant. The average departure date from Lord Howe Island was 08 April (range: 21 March–22 April). The tern’s migration route was northwest towards the eastern Australian coast, skirting the Great Barrier Reef. Terns then spent the non-breeding …

Common Mergansers Mergus Merganser Use Wings To Pursue A Fish Underwater, Anthony B. Lapsansky, Robert H. Armstrong Jul 2025

Common Mergansers Mergus Merganser Use Wings To Pursue A Fish Underwater, Anthony B. Lapsansky, Robert H. Armstrong

Marine Ornithology

Common Mergansers Mergus merganser dive into lakes, rivers, and coastal waters to feed on fish and other aquatic prey. This species and others in the genus Mergus are traditionally classified as foot-propelled divers. When submerged, mergansers are expected to swim by kicking their feet, holding their wings close to their bodies. Here, we report, with video evidence, an event in which four mergansers used their wings underwater to chase down and capture a large fish. Documentation of wing use by this classically defined “foot-propelled diver” illustrates the gaps in our understanding of avian diving physiology, hydrodynamics, and behavior.

Spatial Effects In Relation To Reproductive Performance Of Common Murres Uria Aalge At A Re-Established Colony, Gerard J. Mcchesney, Julie L. Yee, Michael W. Parker, William M. Perry, Harry R. Carter, Richard T. Golightly, Stephen W. Kress

Marine Ornithology

A main goal of seabird colony restoration is for the colony to become self-sustaining. To do so, elevated rates must be attained in (1) reproductive success and (2) recruitment by immigrants and birds produced at the colony. Thus, an understanding of the factors affecting reproductive success and recruitment at restoration sites is vital. We examined how spatial features at the colony level affected reproductive success of Common Murres Uria aalge (hereafter, murres) over a six-year period at Devil’s Slide Rock, California, a colony re-established using social attraction techniques. Clusters of sites with similar egg-laying dates, as well as high hatching …

Albatross Population Monitoring Using Satellite Imagery, A Case Study: Short-Tailed Albatross Phoebastria Albatrus At The Senkaku Islands, Nigel Brothers, Catherine Bone, Alexia Wellbelove Jul 2025

Albatross Population Monitoring Using Satellite Imagery, A Case Study: Short-Tailed Albatross Phoebastria Albatrus At The Senkaku Islands, Nigel Brothers, Catherine Bone, Alexia Wellbelove

Marine Ornithology

Accurate monitoring of vulnerable albatross populations is essential to their conservation. Herein, we explore the prospect of monitoring one particular remote albatross population with a view to promoting accurate worldwide monitoring of vulnerable albatross populations. We used very high-resolution (VHR) satellite images to count nesting Short-tailed Albatrosses Phoebastria albatrus on two islands of the Senkaku group, western North Pacific Ocean, where conventional monitoring has not occurred for 19 years due to a geopolitical territory dispute. Despite count uncertainties across rocky terrain, many birds were clearly discernible using the highest resolution image available of Minami-kojima. The result was a count of …

Using Remote Video Technology To Study Environmental Factors Influencing Productivity Of Black-Legged Kittiwakes Rissa Tridactyla, Sarah A. Tanedo, Tuula E. Hollmén, John M. Maniscalco, Sadie E.G. Ulman

Marine Ornithology

Monitoring seabirds and their responses to ecosystem change provides essential information for understanding the reasons behind any changes in productivity or populations. However, many species nest in remote locations, which poses logistical challenges for long-term studies. Remote cameras offer an opportunity to confront this issue. The Black-legged Kittiwake Rissa tridactyla (kittiwake) has been used as an indicator of changes in its environment and is a prime candidate for monitoring via remote cameras. To investigate the potential for camera application, we used a remote camera system to collect six years (2010–2015) of reproductive data from a sub-colony of kittiwakes in Resurrection …

Normal Physical Parameters Characterizing Galapagos Marine Birds, Gustavo Jiménez-Uzcátegui, Patricio D. Carrera-Játiva, Soledad Sarzosa, Edison Encalada, Richar Rodríguez-Hidalgo, Erika (Travis) Crook, Christian Sevilla

Marine Ornithology

The Galapagos Penguin Spheniscus mendiculus (GAPE), Flightless Cormorant Phalacrocorax harrisi (FLCO), and Waved Albatross Phoebastria irrorata (WAAL) are marine birds that are endemic to the Galapagos Islands. To provide health information for these three species, baseline data on several physiological parameters were collected non-invasively—from individuals and populations appearing to be healthy—during the course of physical examinations that were conducted from 2011–2019. Heart rate, respiratory rate, body temperature, and body condition (weight vs. morphometric measurements) were analyzed as a function of age and sex. Mean heart rate differed significantly between juveniles and adults in all three species. Respiratory rate and body …

Hatching Success Of Common Murres Uria Aalge Is Linked To The Number Of Neighbours And Resource Availability, Amy L. Irvine, Julia E. Gulka, Gail K. Davoren Jul 2025

Hatching Success Of Common Murres Uria Aalge Is Linked To The Number Of Neighbours And Resource Availability, Amy L. Irvine, Julia E. Gulka, Gail K. Davoren

Marine Ornithology

When breeding within densely populated colonies, seabirds benefit from increased offspring protection from predators, but intraspecific competition for resources may outweigh these benefits. We tested whether the number of breeding-site neighbours and days of predator presence influenced the breeding performance of Common Murres Uria aalge at two different-sized colonies off the northeastern Newfoundland coast: Cabot Island (10000 breeding pairs; < 10 km offshore) and Funk Island (500000 breeding pairs; ~60 km offshore). Gulls, the main predators of murre eggs/chicks, inhabit both islands in similar numbers. During July–August 2018, camera traps placed at topographically similar plots on each colony recorded breeding performance metrics (i.e., hatching, fledging, reproductive success), number of breeding-site neighbours, and daily presence of gulls. Hatching success was lower at Funk Island (64.7%) than Cabot Island (96.2%), but nearly all hatched chicks fledged at both colonies. Lower hatching success at Funk Island was due to higher egg abandonment and predation. It was also associated with fewer breeding-site neighbours, including non-brooding mates and non-breeders, along with higher gull presence (96.6% of all gull sightings at both colonies). Fewer neighbours at Funk Island may have resulted from mates and non-breeding murres spending more time at sea due to longer distances to predictable foraging sites and higher conspecific densities relative to Cabot Island. In turn, with fewer breeding-site neighbours at Funk Island, parents appeared less able to defend against or deter gull predation. Although Funk Island has special conservation status, protection of Cabot Island may also be important for the long-term conservation of murres in Newfoundland.

Studies Of The Time Budget And Daily Activity Of Common Eider Somateria Mollissima During Incubation, Grigori M. Tertitski, Evgeny V. Semashko, Alexander E. Cherenkov, Vladimir Y. Semashko Jul 2025

Studies Of The Time Budget And Daily Activity Of Common Eider Somateria Mollissima During Incubation, Grigori M. Tertitski, Evgeny V. Semashko, Alexander E. Cherenkov, Vladimir Y. Semashko

Marine Ornithology

In the Common Eider Somateria mollissima, only females incubate the clutch over a period of 25–28 days. Determining their schedule of nest absence, how long they are away, how often, and where they go can be problematic. They must also avoid nest predation while tending to their own needs. We used geolocators to investigate the behavior of incubating females on forested islands in Dolgaya Guba Bay (65°03′N, 035°47′E), White Sea, Russia. Data were obtained for 12 females: three in 2015 and 2016, four in 2017, and two in 2018. During the entire incubation period, females left their nests for the …

Levels Of Predation At Two Leach's Storm Petrel Hydrobates Leucorhous Breeding Colonies, Rielle Hoeg, Dave Shutler, Ingrid L. Pollet Jul 2025

Levels Of Predation At Two Leach's Storm Petrel Hydrobates Leucorhous Breeding Colonies, Rielle Hoeg, Dave Shutler, Ingrid L. Pollet

Marine Ornithology

Seabirds are declining worldwide, and predation by introduced and endemic species is one threat that affects many of them. Leach’s Storm Petrel Hydrobates leucorhous (hereafter LHSP) populations are declining in a number of locations for reasons that are likely multicausal, and perhaps local or regional, but relative contributions of individual causes are poorly understood. To help understand causes, we quantified predation at two Nova Scotian LHSP breeding colonies that differ in predator management: no management occurs on Bon Portage (BP) Island, whereas management is used on Country Island (CI). Transects were monitored for evidence of predation approximately biweekly on BP …

Estimating Streaked Shearwater Calonectris Leucomelas Abundance In The Republic Of Korea Using Automated Acoustic Recorders, Kirk A. Hart, Steffen Oppel, Grant R.W. Humphries, Andrew Blackburn, Ki-Baek Nam Jul 2025

Estimating Streaked Shearwater Calonectris Leucomelas Abundance In The Republic Of Korea Using Automated Acoustic Recorders, Kirk A. Hart, Steffen Oppel, Grant R.W. Humphries, Andrew Blackburn, Ki-Baek Nam

Marine Ornithology

Traditional methods to assess population size in seabirds are applicable only to species that nest in visible locations, leaving cryptic nocturnal, burrow-nesting seabirds underrepresented in typical long-term population monitoring programs. Alternative methods to count burrow-nesting birds, however, are extremely labor-intensive and therefore are applicable only to small and possibly unrepresentative areas, and may have negative effects on burrow-nesting populations. We suggest the use of automatic acoustic recorders as a possible survey technique to overcome logistic difficulties of research of seabirds on remote islands in the Republic of Korea, where funding for ecological research is extremely limited but where globally important …

Non-Breeding Movements And Foraging Ecology Of The Black Guillemot Cepphus Grylle In Atlantic Canada, Julia E. Baak, Marty L. Leonard, Carina Gjerdrum, Mark D. Dodds, Robert A. Ronconi

Marine Ornithology

Understanding the movements of seabirds, which are important ecological indicators, can provide new insights into physical and biological aspects of the marine environment. This information can also be used in planning marine conservation and oil spill response strategies. Though Black Guillemots Cepphus grylle are widely distributed in the coastal waters of eastern and arctic Canada, little is known about their movements during the non-breeding season. We used a combination of global location sensors and stable-isotope analyses on Black Guillemots breeding on Country Island, Nova Scotia, Canada and on Kent Island, New Brunswick, Canada to examine their non-breeding movements and trophic …

Underwater Behavior Of Christmas Shearwaters Puffinus Nativitatis From Kure Atoll, Ilana Nimz, Mark A. Renshaw, Matthew Iacchei, Eric Vanderwerf, Cynthia Vanderlip, Matthew Saunter, Naomi Worcester, K. David Hyrenbach

Marine Ornithology

The Christmas Shearwater Puffinus nativitatis is an aquatic, tropical shearwater. While individuals of this species are known to forage by pursuit plunging and diving, there are no published reports quantifying their sub-surface foraging behavior. We obtained diving information from eight chick-rearing Christmas Shearwaters on Kure Atoll during June–August 2017. Over the 33 days during which instruments were deployed, 1521 dives were recorded. Individual deployments lasted three to eight days and were independent of the maximum depths recorded. Individual maximum depths were 10.7–24.1 m, averaging 15.4 m. While the deepest and longest recorded dive reached 24.1 m and lasted 31 s, …

Trends In Density, Abundance, And Response To Storm Damage For Westland Petrels Procellaria Westlandica, 2007-2019, Susan M. Waugh, Christophe Barbraud, Karine Delord, Kate L.J. Simister, G. Barry Baker, Georgie K. Hedley, Kerry-Jayne Wilson, Douglas R.D. Rands

Marine Ornithology

The density and distribution of Westland Petrel burrows was assessed over a 12-year period (2007–2019). During that time, burrow density increased while occupancy remained stable, commensurate with an annual population growth rate of 1.022 (95% confidence interval: 0.971–1.076), as estimated using mark recapture data. From our surveys, we estimated a 2019 baseline population of ~6200 breeding pairs and a world population of 13 800–17600 individuals, covering around 95% of the population. Transects were conducted to establish the location and density of 17 petrel sub-colonies in rugged, untracked terrain in Paparoa National Park, West Coast, New Zealand. Major storms in 2014–2018 …

Responses Of Sympatric Shearwaters To Supplemental Food Under Varying Natural Prey Availability On The Wintering Grounds Of Coastal Newfoundland, Canada, Paloma C. Carvalho, Laurie D. Maynard, Gail K. Davoren Jul 2025

Responses Of Sympatric Shearwaters To Supplemental Food Under Varying Natural Prey Availability On The Wintering Grounds Of Coastal Newfoundland, Canada, Paloma C. Carvalho, Laurie D. Maynard, Gail K. Davoren

Marine Ornithology

Species tend to concentrate in areas with high prey availability, which could lead to competitive interactions within a feeding assemblage as resources become depleted. In coastal Newfoundland, Canada, capelin Mallotus villosus is the focal forage fish species that many top predators feed on during the summer; however, inshore availability varies throughout the boreal summer when abundant aggregations migrate inshore to spawn. We investigated the interactions and responses of Great Shearwaters Ardenna gravis and Sooty Shearwaters A. grisea during their non-breeding season to supplemental food supply under changing natural prey availability (higher and lower capelin availability) by conducting an at-sea experiment …

Wedge-Tailed Shearwater Ardenna Pacifica Fallout Patterns Inform Targeted Management, Brooke Friswold, Keith Swindle, David Hyrenbach, Melissa R. Price Jul 2025

Wedge-Tailed Shearwater Ardenna Pacifica Fallout Patterns Inform Targeted Management, Brooke Friswold, Keith Swindle, David Hyrenbach, Melissa R. Price

Marine Ornithology

Seabird fledglings are often attracted to artificial, bright lights, leading to their grounding. This phenomenon is termed “fallout” and is associated with an increased risk of mortality from land-based threats. This study evaluated temporal trends and spatial factors, such as fallout clustering near lights and proximity to colonies, to inform targeted management actions. Standardized surveys were conducted from 2002 to 2010 for Wedge-tailed Shearwater Ardenna pacifica (WTSH) fallout on the island of O‘ahu, Hawai‘i, USA. First, yearly fallout counts along the transect showed a two-year cycle and identified 25 November as the date with the highest fallout across years. Second, …
