Changes in ocean temperature disrupt the distribution and abundance of prey, leaving birds struggling to find enough to eat. Migratory patterns are thrown into disarray as birds grapple with altered habitats and unpredictable weather patterns. Imagine a Sanderling, arriving at its usual wintering spot only to find it underwater. Climate change is impacting these sensitive migratory patterns.

Disturbance: The Unwelcome Guests

Human disturbance, often unintentional, can have devastating consequences. Recreational activities, like beach volleyball and kite flying, can disrupt nesting birds, causing them to abandon their nests and chicks. Noise pollution, from traffic and construction, can interfere with their communication and foraging behavior. Off-leash dogs, while seemingly harmless, can chase and harass birds, depleting their energy reserves and increasing their vulnerability to predators. Think of a peaceful beach scene shattered by the unintended consequences of human recreational activities, leading to nest abandonment and reduced breeding success.

Predation: A Feline Foe

Finally, we have predation, particularly from introduced predators like feral cats, rats, and foxes. These non-native species, often thriving in human-modified landscapes, can decimate bird populations, especially nesting birds. Feral cats, in particular, are notorious predators, relentlessly hunting birds and destroying nests. Imagine a Snowy Plover nest, carefully camouflaged in the sand, falling victim to a hungry feral cat. The delicate balance is disrupted by these introduced predators, making it harder for native bird populations to thrive.
