The mystical oilbird
In a serendipitous encounter, an oilbird was discovered roosting at St. Benedict’s College in La Romaine, south Trinidad, far from its known colonies. This rare sighting provided a unique teaching opportunity for the school staff. The oilbird, a nocturnal marvel, is one of the most remarkable yet overlooked species in Trinidad’s rich biodiversity. Unlike the vibrant hummingbird or the powerful hawk-eagle, the oilbird’s unassuming appearance belies its extraordinary adaptations and ecological significance. Native to Trinidad, which shares much of its ecology with South America, the oilbird thrives in darkness, spending its days in lightless caves and emerging at night to forage. With a wingspan exceeding one metre, these birds embark on nightly journeys, sometimes covering over 100 kilometres in search of their exclusive diet of fruits from palms, laurels, and bursera trees. This dietary specialization makes them vital seed dispersers, ensuring the propagation of their food trees. Oilbirds possess unique sensory adaptations, including echolocation and an unparalleled sensitivity to light, with retinal rod densities of one million rods per millimetre—the highest among vertebrates. Their social structure is equally fascinating, with monogamous pairs raising broods in large colonies that can number in the thousands. Despite their ecological importance, oilbirds face threats from human exploitation, historically hunted for their oil and meat. Conservation efforts are crucial to protect this enigmatic species and its habitat, ensuring its survival alongside humanity.

La Nina is back, but impact may be limited— US agency
The United States National Weather Service (NWS) confirmed on Thursday that La Nina, a natural climate phenomenon, has re-emerged. However, its weak intensity is expected to minimize its cooling effect on global temperatures and its influence on Atlantic hurricane activity. La Nina, characterized by cooler-than-average sea surface temperatures in the central and eastern equatorial Pacific Ocean, typically alters atmospheric wind patterns, leading to increased hurricane activity in the Atlantic basin and reduced activity in the Pacific. This cyclical pattern oscillates between La Nina, its counterpart El Nino, and neutral phases. After a brief La Nina episode from December 2024 to March 2025, neutral conditions prevailed until the recent resurgence of La Nina in September 2025. The NWS predicts that La Nina will persist through the winter, with a 55% chance of transitioning back to neutral conditions between January and March 2026. Despite its historical impact on global weather, this La Nina event is expected to be too weak to significantly affect conventional winter weather patterns. The 2020–2023 La Nina was notable for its unprecedented duration, marking the first ‘triple-dip’ event of the 21st century. While La Nina typically cools global temperatures, it failed to counteract the trend of record-breaking heat observed over the past decade. The Atlantic hurricane season, which runs from June 1 to November 30, has been slightly below average so far, with no storms making landfall in the United States. Nevertheless, the National Oceanic and Atmospheric Administration (NOAA) continues to forecast an above-normal hurricane season.
