A recent study has shed light on the unusual digestive habits of streaked shearwaters, revealing that these birds expel waste far more often than anticipated, particularly during flight. This groundbreaking research, conducted by scientists at the University of Tokyo, initially aimed to observe the birds' flight mechanics but inadvertently unveiled a consistent and rapid defecation pattern. The continuous expulsion of guano by these seabirds, which largely occurs over the open ocean, suggests a previously underestimated influence on marine nutrient cycles and the health of surrounding ecosystems.
Detailed Insights into Avian Physiology and Ecological Impact
In a fascinating revelation in August 2025, behavioral ecologist Dr. Leo Uesaka from the University of Tokyo embarked on an innovative research endeavor. Employing miniature cameras strategically placed on the underbellies of streaked shearwaters, his initial objective was to meticulously document their distinctive take-off behaviors from the water's surface. However, the resulting footage presented an unforeseen and striking pattern: the birds exhibited an astonishingly high frequency of waste excretion while airborne. This unexpected observation prompted Dr. Uesaka to pivot his research focus, leading to a significant finding published in the esteemed journal, Current Biology. The study revealed that these majestic birds, which predominantly forage across the vast expanse of the western Pacific, defecate, on average, more than five times an hour during flight. Intricately, the researchers found that these birds almost never relieve themselves when resting on the water's surface, a behavior possibly linked to maintaining hygiene, evading predators, or simply for comfort. By collecting guano from birds temporarily housed in controlled conditions, the team estimated that streaked shearwaters can excrete up to 5% of their body mass hourly, highlighting the sheer volume of waste discharged. This continuous aerial deposition of nutrient-rich guano – packed with nitrogen and phosphorus – suggests a profound, yet previously overlooked, role in fertilizing specific oceanic regions. Experts like Kyle Elliott, a behavioral ecologist from McGill University, further emphasized that the energetic cost of flight for these birds is surprisingly less than resting on water, making frequent mid-air excretion a plausible strategy to reduce their physiological load. Marine ecologists, including Ruth Dunn from CNRS in France, concur that such concentrated nutrient dispersal could significantly boost the productivity of marine life, akin to the thriving coral and fish populations observed around islands frequented by seabirds.
This pioneering investigation into the frequent defecation patterns of streaked shearwaters offers compelling insights into the intricate relationship between avian biology and marine ecology. It underscores the importance of even the most basic physiological processes in shaping broader environmental dynamics. From a scientific perspective, this study serves as a powerful reminder that sometimes, the most profound discoveries emerge from unexpected observations, challenging us to look beyond conventional research avenues. From a broader environmental viewpoint, it compels us to appreciate how seemingly minor contributions, like bird droppings, can collectively play a pivotal role in sustaining the delicate balance of our planet's ecosystems. This work not only enhances our understanding of seabird behavior but also highlights the critical, yet often unseen, ways in which wildlife actively participates in maintaining the health and vitality of our oceans, urging continued research into these vital natural processes.

\nThis report delves into a strategic reassessment of the iShares MSCI Canada ETF (EWC), an exchange-traded fund offering targeted exposure to Canadian equities, primarily focusing on large and mid-cap corporations. While a cautionary stance was adopted previously, recent performance data reveals that EWC has significantly outperformed the S&P 500 over the last year. This unexpected trajectory highlights the fund's intrinsic value as a diversification tool for portfolios heavily concentrated in U.S. assets. A key factor contributing to Canada's market resilience and EWC's robust performance lies within its banking sector, which constitutes a substantial portion of the fund's holdings. These financial institutions are noted for their ample capital reserves, providing a crucial buffer against potential credit market vulnerabilities. This analysis underscores the enduring utility of EWC in mitigating geographic investment risks and its promising outlook within the global financial landscape.
Reframing Canadian Equity: A Year of Unexpected Gains
In the vibrant heart of North America's financial landscape, the iShares MSCI Canada ETF (EWC) has become a focal point for investors seeking diversification beyond the dominant U.S. market. This fund specifically targets the dynamic realm of Canadian equities, casting a wide net over established large and mid-cap companies. A year ago, a cautious outlook on this particular market segment was prevalent. However, the ensuing twelve months have unveiled a surprising narrative: EWC has not only defied expectations but has markedly surpassed the performance of the S&P 500.
This impressive resurgence underlines EWC's critical role in a balanced investment strategy. For portfolios predominantly anchored in U.S. stocks, the inclusion of EWC offers a strategic avenue to mitigate geographic concentration risk. A significant bedrock of EWC's stability and growth stems from its substantial allocation to Canada's robust banking sector.
