Long Island's wildlife has faced a brutal winter, with temperatures barely rising above freezing for weeks. But how have the animals survived this icy onslaught? Let's delve into the fascinating strategies they employ to endure the cold and snow.
Before a brief thaw this week, Long Island experienced a relentless cold snap, with temperatures hovering at or below freezing for 16 out of 17 days. Waterways froze solid, and the ground remained blanketed in snow from a powerful January storm. While humans sought refuge indoors, the region's wildlife had to adapt and survive.
Here's the surprising part: Despite the harsh conditions, experts assure us that most species are well-equipped to handle the cold. Stony Brook University biologist Resit Akçakaya explains, "Organisms have three options: migrate, hibernate, or tolerate the cold. Most non-migratory species can withstand these temperatures." But what does this mean for individual animals?
Newsday's investigation reveals a mixed bag:
- The January storm continues to impact the ecosystem, benefiting some species while challenging others.
- Snow cover affects feeding patterns, and while some animals may struggle to find food, population-level impacts are unlikely.
- Physiological and behavioral adaptations, like a seal's blubber or a deer's foraging adjustments, play a crucial role in survival.
Robert Marsh, a natural resource supervisor, emphasizes, "These animals have evolved over millennia to thrive in such conditions. Even in recent decades, we've seen colder winters."
The Calorie Challenge: Winter on Long Island isn't just cold; it's a time of scarce food resources, especially for warm-blooded creatures. Kelly Hamilton, a wildlife biologist, notes the difficulties faced by waterfowl and land animals in finding sustenance. Prey species, like chipmunks and voles, seek warmth underground, making them harder to catch.
But here's where it gets interesting: Some animals, like white-tailed deer, have remarkable strategies. Matt Ross from the National Deer Association explains that deer store fat during late summer and fall, increasing their body weight by up to 30%. This fat reserve sustains them through winter, even with limited food options. Their thick winter coats and efficient circulatory systems further aid survival.
Controversial Question: Could this winter's conditions lead to a decline in certain bird populations? Joyann Cirigliano, a bird expert, observes that birds are flocking to feeders due to snow-covered food sources. Robins, for instance, are resorting to less nutritious berries from invasive plants. Should we intervene with bird feed, or let nature take its course?
The Cat Conundrum: Community cats, including ferals and strays, number in the tens of thousands on Long Island. Elyise Hallenbeck, leading the Bideawee Feral Cat Initiative, highlights their resourcefulness in finding warmth. DIY winter shelters, insulated boxes filled with straw, can be lifesavers during extreme weather.
Migration and Adaptation: Many fish species migrate south to escape the cold, preventing fish kills. Sea turtles also migrate, but seals thrive in these conditions, thanks to their blubber and fur. Interestingly, some seal species even eat snow for hydration.
A Silver Lining for Spring: The snow cover has a positive aspect—it retains moisture, benefiting the region's mild drought conditions. Rebecca Slagle, a sustainability coordinator, notes that the cold may also control pests and invasive plants, potentially aiding native species.
Nature's Resilience: Despite the challenges, wildlife persists. Biologist Lisa Filippi's trek through the snow revealed fewer animal tracks, but she spotted a healthy coyote, likely feasting on rabbits. While some individual deaths are expected, the overall ecosystem remains resilient.
As we marvel at these survival stories, it's essential to consider: How can we support local wildlife during extreme weather? Should we intervene, or let nature's balance prevail? Share your thoughts and join the discussion!
