Summer spreads wildlife across the landscape, and winter gathers it. Cold, snow and scarce food push animals into smaller areas, where open water, warm springs, salmon runs or protected breeding beaches create dramatic concentrations. Birds migrate to refuges, marine mammals head for sheltered coasts, and predators follow prey into valleys. For travelers, that means the cold months can offer some of the best wildlife viewing of the year, with fewer crowds and clear air. Some of the events below last only a few weeks, and others are tied to specific places that are well managed to protect the animals. Timing varies from year to year with weather, water temperature and food supply, so check with refuges, parks and local guides before planning a trip. Viewing rules matter, because disturbance in winter can cost animals scarce energy. Keep your distance, follow posted guidance, use binoculars and long lenses and stay on established paths. The ten spectacles here range from desert wetlands to ocean coastlines and mountain valleys, and each rewards an early start and patience.
Bosque del Apache National Wildlife Refuge, along the Rio Grande south of Socorro, is one of the great winter wildlife shows in the country. The season runs from late October to March and peaks in December and January, when tens of thousands of sandhill cranes and snow geese gather on the ponds and fields. At dawn, the birds lift off together in what photographers call the blast-off, a thunderous departure that can involve 20,000 geese or more. At sunset, they return in waves, filling the sky with sound. Bald eagles also spend the winter here, and the refuge hosts a festival each November. The best viewing is at sunrise and sunset, so dress for cold desert mornings and bring a tripod and binoculars. Observation decks and a loop road provide access, and the visitor center has current counts. Rules protect the birds from disturbance, so stay on the paths and in your vehicle where required. The refuge is about 90 miles south of Albuquerque.
Every winter, hundreds of bald eagles gather along the Skagit River in northwest Washington to feast on spawned-out chum salmon. The birds arrive from Alaska and British Columbia in December, and numbers typically peak in January, making the Skagit one of the largest wintering eagle concentrations in the lower 48 states. Eagles perch in cottonwoods along the banks and on gravel bars, and the best viewing is in the morning, when they are most active. Roadside pullouts between Rockport and Marblemount provide easy access, and rafting trips offer a close but respectful view. The Skagit Wild and Scenic River system protects the habitat, and local groups host an eagle festival in late January. Expect cold, wet weather in the Cascades foothills and dress in layers. Keep a distance and avoid flushing the birds, since each flight burns energy they need to survive the winter. Other wildlife includes trumpeter swans, otters and harbor seals near the estuary. Check river and road conditions, because floods and snow can affect travel.
When Gulf of Mexico water cools in winter, Florida manatees move into warm freshwater springs, and Crystal River on the state's west coast hosts one of the largest gatherings. The springs hold a steady temperature around 72 degrees Fahrenheit, a refuge for animals that can suffer cold stress when water drops below about 68. From November through March, hundreds of manatees rest in the spring-fed waters of Kings Bay and Three Sisters Springs, part of the Crystal River National Wildlife Refuge. Visitors can watch from boardwalks or join permitted snorkel tours, where strict rules require quiet, passive observation and no touching. The best viewing is on cold mornings, when the animals are most concentrated. The species was listed as threatened in 2017, after being listed as endangered, though numbers face pressure from boat strikes, red tide and habitat loss. Respect manatee zones, follow slow-speed rules and choose a licensed operator. Winter is also the season of cold snaps, so bring a wetsuit if you plan to get in the water.
Each winter, northern elephant seals haul out on the beaches of central California to give birth and mate, and the scene is raw and loud. Ano Nuevo State Park, about 55 miles south of San Francisco, is one of the largest mainland breeding sites. Males, weighing up to two tons, arrive in December and battle for dominance, rearing up and crashing into each other. Females arrive soon after, give birth to pups and nurse them for about a month before mating and heading back to sea. The peak of the breeding season runs through February. During the season, the park offers docent-led walks that must be reserved in advance, and access to the beaches is limited to protect the animals. Piedras Blancas, farther south near San Simeon, has a free viewing area. The animals are surprisingly vocal, with deep belches and roars. Stay at least 25 feet away and never approach, since the seals can move fast and bite. The species recovered from near extinction in the 1890s, a conservation success.
Western monarch butterflies, which breed across the western states, migrate to the California coast each autumn and cluster in groves of eucalyptus, Monterey pine and cypress. Sites such as Pismo Beach State Beach, Pacific Grove and Santa Cruz host clusters from about November through February, when thousands of orange wings hang like leaves from branches. On cold mornings, they stay tightly packed, and when the sun warms the grove, they flutter off to feed and drink. Counts conducted by the Xerces Society have shown a sharp decline since the 1980s, with historic lows in recent years, which makes each cluster precious. Viewing is free at many sites, and docents often provide talks on weekends. The best time of day is mid-morning, when the sun lights the clusters. Do not touch or shake the trees, and keep your voice low. Eastern monarchs migrate to the oyamel fir forests of central Mexico, a separate winter spectacle. The butterflies need protection, and visitors can help by respecting closures and planting native milkweed at home.
Gray whales make one of the longest migrations of any mammal, traveling roughly 10,000 miles round trip between feeding grounds in the Arctic and breeding lagoons in Baja California. The southbound migration passes the California coast from December through January, and the northbound trip, with mothers and calves, runs from February through April. From headlands such as Point Loma in San Diego, Point Reyes and Cabrillo National Monument, watchers can see spouts and flukes a mile or two offshore. Whale-watching boats operate from ports along the coast, and in the Baja lagoons of San Ignacio and Magdalena Bay, friendly whales approach small boats in January through March, in guided and regulated encounters. The eastern North Pacific population was removed from the endangered species list in 1994, though it has experienced die-offs in recent years. Bring binoculars, windproof clothing and motion-sickness remedies if you plan to go out on a boat. Choose operators that follow federal approach rules, which keep boats at a respectful distance from the whales.
Each winter, thousands of North Pacific humpback whales travel from Alaska to the warm shallow waters around Hawaii to breed and calve. The season runs from about December to April, with peak numbers in January through March, and the waters off Maui are among the best places in the world to see them. Males sing long, complex songs that can be heard underwater, and they compete in boisterous groups, leaping and slapping the surface. Mothers nurse calves in the calm waters of Maalaea Bay and Lahaina. Watchers can see breaches from the shore at many beaches and from cliff-top overlooks. The Hawaiian Islands Humpback Whale National Marine Sanctuary protects the species, and federal rules require boats and swimmers to stay at least 100 yards from the whales. Choose licensed tour operators, and never attempt to swim with whales. The population has recovered substantially since commercial whaling ended, though entanglements and ship strikes remain threats. Bring sunscreen and binoculars, and plan for early morning trips, when the water is calm.
Winter is the best time to see wolves in Yellowstone National Park, and the Lamar Valley in the northeast corner is the place to look. Snow makes the animals easier to spot against the white landscape, and wolves descend to lower elevations following elk and bison. The road from the park's North Entrance at Gardiner to Cooke City is kept open all year, giving access to the valley by car. Wolf watchers set up spotting scopes at dawn at pullouts along the road and wait, often with the help of volunteers and local guides. Other winter sightings include coyotes, bighorn sheep, bison with frosted faces and the occasional fox. Wolves were reintroduced to Yellowstone in 1995 and 1996, and their return changed the ecosystem, though the details are still being studied. Temperatures can drop well below zero, and vehicles need winter tires. Stay inside designated areas and remain at least 100 yards from wolves and bears. Bring warm layers, a thermos and patience, because sightings are never guaranteed.
Just outside Jackson, Wyoming, the National Elk Refuge protects winter range for one of the largest elk herds in North America, with thousands of animals gathered on the valley floor from late fall through spring. Snow forces the elk down from the high country of Grand Teton and the surrounding forests, and the refuge provides open meadows and, in harsh winters, supplemental feed. Visitors can take horse-drawn sleigh rides from the Jackson visitor center, typically from late December to early April, that run through the herd, offering a close look at the animals without disturbing them. The Teton Range rises behind the valley, creating a postcard backdrop. Other wildlife includes bighorn sheep, trumpeter swans, coyotes and bald eagles. Ticket sales support the refuge, and reservations are wise. Dress warmly, since the sleigh ride is open to the cold air. Elk shed their antlers in late winter, and the refuge hosts an antler collection and sale to benefit habitat management. Respect closures, which protect the animals from stress during the hardest months.
Every few winters, snowy owls arrive in the lower 48 states in numbers that surprise birders. These large white owls breed on the Arctic tundra and move south when food runs short or when a good breeding year produces many young. They are most likely to be found from December through February, in open landscapes that resemble tundra: farm fields, airports, dunes, beaches and the shores of the Great Lakes. Duluth, Minnesota, the coast of Massachusetts and the prairies of the Dakotas are classic spots. Snowy owls hunt in daylight and often perch on fence posts, rooftops or hummocks, which makes them easier to see than most owls. Look for a white shape in a field, often with dark barring on females and young. Because the birds are stressed and hungry after long journeys, wildlife groups ask viewers to keep a distance of at least 100 yards, never to flush them or bait them, and to use a long lens. Local bird alert networks report current sightings. The visits show how far wild animals travel in winter.
