March Birding Forecast

On March 1, Southern Nevada receives about eleven hours and twenty-six minutes of direct daylight. This is about an hour more of total daylight compared to that on February 1, and about an hour and forty minutes more than on January 1. On the last day of March, we receive about twelve and a half hours of daylight. The increased daylight in the northern hemisphere brings increased warmth. The additional light and heat give plants energy to photosynthesize and kickstarts the processes of putting out new leaves and flowers. Insect activity follows and ramps up.


In sync with the progressions of the seasons are billions of waterfowl, shorebirds, raptors, hummingbirds, and songbirds. Across their wintering grounds in South and Central America, Mexico, or the Sonoran Desert, these birds are fattening up and saving their energy for long, challenging journeys. Like the plants and insects, these birds register the increasing sunlight; cascades of hormonal changes prepare them for a seasonal movement that we call migration. Of these billions of birds, many millions will pass though Nevada’s skies this spring.


March offers a preview for what’s in store for April and May. Although March may have days that feel like spring, there are days that potentially can be reclaimed by winter weather. This means that for many songbirds, it may be too energetically taxing and risky flying northwards into our region in March. It could even be fatal if an intense cold snap occurred. A few species of land birds do manage to successfully navigate the temperamental month of March, seemingly adapted to cope with the unpredictability. 


These birds include Yellow-headed Blackbirds and cowbirds, which are sometimes coming from marshes and agricultural areas of Southern Arizona or northern Mexico, are some of the first to arrive. You may find or hear these birds at familiar parks, especially any with stands of wetland vegetation or large lawns. Their relative, Hooded Orioles, come back by late March, preferring to be closer to trees such as palms.


Along the Colorado River or Clark County Wetlands Park, the Lucy’s Warbler begins to trickle in. These small, gray warblers seek out stands of mesquite tress, joining the assemblage of overwintering Yellow-rumped and Orange-crowned Warblers. The Lucy’s Warbler winters as close by as the Mexican state of Sinaloa. This means that the distance that they needed to traverse to get to Southern Nevada is far less than that of comparatively sized warblers wintering deeper into Mexico and helps explain why we see these warblers arrive well before the others. It’s one of the only warblers to breed in tree cavities, and they prefer mesquite groves and wooded wetlands for nesting habitat.


Other birds on their way through Nevada in March are swallows. These strong flyers are diurnal migrants, and unlike most other songbirds, they have the advantage of being able to hunt flying insects as they migrate northbound. Tree, Violet-green, Barn, Northern Rough-winged and Cliff Swallows may be seen cruising low and purposefully northward through open desert or stopping to feed and drink anywhere with surface water. Some of the Northern Rough-winged or Cliff Swallows may end their spring journey in Las Vegas or Henderson, as some create nests under bridges at locations like Arroyo-Grande Park or Pittman Wash.


Other birds are departing our region. The wintering duck numbers begin to thin out at the popular birding sites in the region. Geese and ducks are well-adapted to finding food in winter but often driven by accessible bodies of water for roosting or foraging. With lakes and ponds thawing out to the north, they will largely begin departing the region for the wetlands of the Great Basin and prairies of the west, the spruce forests of Canada or Alaska, or even the tundra of the Arctic.


Close to your home, you may be observing flurries of breeding behavior from resident doves, hummingbirds, and songbirds. These birds that often live their entire lifecycles in the same region breed well before some birds have begun migratory journeys that can be hundreds or thousands of miles in duration. These are the Anna’s Hummingbirds, Verdins, and Northern Mockingbirds. It’s possible that by late March you may see robins or local birds feeding young in nests.


Like every year, month, or week, no day is the same when observing birds. Each species has its own unique life history. As you get outside in March, you’ll be able to observe behavior changes amongst species and individuals. Tune in to these subtle changes and watch for the trickle of incoming spring migrants. And come April, the dam breaks, and the flycatchers, vireos, warblers, orioles and tanagers begin to pour in.

January Bird Forecast

December 27, 2025
by Alex Harper Cold, dense air blankets the valleys and basins of the lowlands, and snow may cover mountain slopes. The sun arcs low across the horizon, and the days are especially short. Just about all the deciduous trees have lost their leaves after a few windy December days. The loss of leaf cover forces some songbirds to forage lower to the ground or move around locally to find fuel and cover. Since insects may only be active during the warmest parts of the warmest of January days, you may notice Ruby-crowned Kinglets and Yellow-rumped Warblers using ingenuity to find dormant or dead insects and spiders. In lots and natural areas, White-crowned Sparrows and House Finches feed on seeding quailbush. Many January days can be bone-chilling, but on calm and warmer days, signs of breeding activities will be noticeable in urban areas. You may hear the loud popping sounds of displaying Anna’s Hummingbirds, see Eurasian Collared-Doves “paragliding” between powerlines, or notice robins and mockingbirds tuning up their songs. This is in response to the gradual increase in daylight following the winter solstice in December; birds are so attuned to light that some resident species may get a jumpstart on establishing territories and attracting mates. Wetlands, parks with water, and golf courses can host high species of duck diversity. Along the Las Vegas Wash from the upper wash to Lake Las Vegas, open water attracts teals, Mallards, American Wigeons, pintails, Gadwalls, Ring-necked Ducks, and Lesser Scaups. Wigeons and Gadwalls are especially drawn to weirs, where they feed on algae growing on rocks. Northern Shovelers may be absent along the Wash, preferring the calmer waters of the Henderson Bird Viewing Preserve. American Wigeons, Ring-necked Ducks, and Redheads all may be found at city park ponds and lakes, where they have learned to take handouts. Geese move in between nighttime roosts around water for open grassy areas during the day. Geese are grazers, and you may see small groups of Snow Geese and the odd Cackling, Greater White-fronted, or Ross’s Geese among Canada Geese on soccer fields or golf course lawns. Lake Mead can attract grebes, loons, and diving ducks. Check the areas where the Las Vegas Wash meets the lake, which is currently near Government Wash and 33-Hole. Large enough fish for grebes, loons, and cormorants are attracted to this outwash, and it can be an excellent place to look for these and other waterbirds that eat medium-sized to large fish. Lake Mead is also attractive to gulls in January and late winter. Gulls are dynamic, intelligent, can be difficult to identify to a species-level, and are prone to wandering. For these reasons and more, birders often find looking for gulls an exciting challenge. Only a few species are expected on any given visit to Lake Mead, but the reservoir lures in just about any North American gull species. Gulls go where they are fed, and they roost in safe areas close to consistent feeding areas. 33-Hole, Government Wash, Boulder Beach and Hemenway Harbor are all tried-and-true locations to look for gulls. Scan through flocks of ubiquitous Ring-billed, California, and occasional Herring for Lesser Black-backed and Iceland Gulls. Eventually, you may see something completely unexpected. Overall, January can be used to see waterfowl move and court one another, as well as life cycles of wintering and resident birds. For some bird species, they are weeks or months away from migrating to their breeding grounds, which in some cases may be in Canada or Alaska. For our year-round neighborhood birds, they may be transitioning out of their winter behavior of wandering for food and beginning to set up territory. By February, we will welcome the vanguards of returning swallows.

December Birding Forecast

December 1, 2025
In December, it is fair to say that winter has arrived. And throughout November, diehard birders and backyard birders alike turn over the stones to see or hear what types of wintering birds will be with us for the next few months. At parks, in canyons, and neighborhoods, our songbirds have mostly settled into their wintering areas. Mixed flocks of Ruby-crowned Kinglets, Yellow-rumped, and Orange-crowned Warblers rove through a variety of habitats. White-crowned Sparrows move confidently in large groups, aggregating where food is plentiful. You may see them around seeding quailbush in much of the valley. Look for their cousins, White-throated and Golden-crowned Sparrows, which occasionally join groups of White crowned Sparrows. For the most part, songbirds tend to stay put once they find a wintering area. They are no longer migrating long distances, but they will move around locally and wander for food supplies. Some songbirds are a little less predictable. Red-breasted Nuthatches and a few finch species are such examples. They move around more freely throughout the winter, admonishing the idea that we usually have of songbirds: that they are supposed to move roughly north or south with the spring or fall. For birds like siskins, Evening Grosbeaks, and Red Crossbills, this may not be the case. These species are more nomadic, searching valleys and mountainous areas for their favored seed crops. Finches call frequently while in flight, so familiarizing yourself with their calls will help you detect them as they flyover. Detecting finches as “fly overs” is a common occurrence with this globally successful family of birds. At our wetlands and lakes, waterbirds move about in search of optimal feeding areas. Many of our geese and ducks continue to come and go as the winter season progresses. These birds are often hunted or disturbed in many wintering areas, so over time they naturally end up at wetlands where hunting is not permitted. It is in part for this reason that you will run into slightly more or different birds at places like Clark County Wetlands in January than you will in December. For those looking to get out of the city for a day of birding, consider visiting agricultural areas around Moapa Valley or south of Laughlin. Visiting these habitats during the winter can be highly rewarding. Agricultural areas attract heaps of bluebirds, pipits, blackbirds and sparrows. And with those, predators often follow; the Moapa Valley, Overton, and Warm Springs areas can be excellent places to see wintering falcons, Red-tailed Hawks and harriers. You may even spot a Ferruginous Hawk, the largest hawk in on the North American Continent. Another good reason to bird these areas is that few people often do. If you are the type of person that loves to sleuth around for interesting birds, you may well stumble across an unusual bird that no one else has detected yet. They are out there, and uncommon and rare birds will be found by local birders.

Birding at Primm: An Interstate Oasis for MIgrants and Birders

By Alex Harper • October 31, 2025
When the days grow shorter, the nights cooler, and winds begin to turn south, many birds begin to change their behaviors. The breeding season has come and gone. Some species spend their lives close to home, perfectly adapted to their habitats through all seasons. But for most North American songbirds, migration is a necessary annual act of survival in the seasonal pursuit of food, water, and safety. These include flycatchers, vireos, thrushes, sparrows, blackbirds, warblers, tanagers, grosbeaks, and buntings. As insects vanish and leaves fall across northern regions, many birds push south, traversing mountains, valleys, and deserts in search of suitable habitat. Many of these birds are intending to make their way to the warmer climates of Mexico and more tropical areas for the colder months. In the arid expanse of the Mojave Desert, safe stopover sites are few and far between. Migrants that are not desert specialists often must locate oases, which are small pockets of water, shade, and food, to rest and refuel. Some are natural: mountain springs and creeks, valley wetlands, or canyons. Others are entirely human-made: parks, cemeteries, and towns where irrigation and ornamental trees create relatively lush islands in a sea of desert. These green patches, although artificial, can mean the difference between exhaustion and success for a traveling flycatcher or warbler. One such refuge sits right on the California-Nevada border along I-15. This is the “town” of Primm. To most travelers between Los Angeles and Las Vegas, it’s another brief stop for gas and food. A defunct roller coaster and closed shopping outlet give the impression that Primm’s prime is behind us. But for birders, it’s a birding hotspot. Primm’s irrigated lawns and runoff from water sources draw birds from miles around. Its small size makes it easy to cover, and its isolation makes it stand out. It’s an island of green surrounded by dry lake beds and sparse vegetation. Primm is a classic “migrant trap,” where the color green and promise of water concentrates birds in one small place. Though songbirds navigate with remarkable precision by reading the stars, reading the Earth’s magnetic fields, and using landmarks - they do sometimes go astray. Young or disoriented individuals may travel the right distance but in the wrong direction, bringing eastern or Great Plains birds into western deserts. For birders, these navigational errors are the source of exciting discoveries, especially in the Fall. When one rare bird is found, more often follow. This is the “Patagonia Picnic Table Effect,” named after a famous site in Patagonia, Arizona, where a single unusual sighting decades ago triggered a rush of birders who went on to discover even more rarities. Primm functions much the same way: one exciting report draws others to look, and the increased attention yields more discoveries. The town’s lawns and patches of trees may not be appealing, but birders affectionately call it the “Primm Forest Preserve,” a tongue-in-cheek tribute made by biologists working in the region in the mid-2010s. The Fall of 2025 was especially exciting, with Baltimore Oriole, multiple Painted Buntings, a Blackburnian Warbler, Yellow-throated Warbler, and more showing up in a short amount of time. As birder and biologist Michael McCloy shared, “This oasis contains some of the only real trees and water for miles, acting as a magnet for any migrating songbirds in need of rest and refueling.” During his near-daily visits this September, he witnessed moments of pure wonder: “One day I turned around and there was a Lark Bunting and a Dickcissel at the same roadside puddle. Another day, a Marsh Wren perched twenty feet up in a tree. And when a Black-throated Blue Warbler showed up, it came within three feet of me. I wondered if it was going to land on my arm.” For Clayton Peoples, who visits regularly from Reno, Primm has become a staple of southern Nevada birding. “It’s one of my go-to places,” he said. “I used to stay at Buffalo Bill’s just to be right there at sunrise.” Clayton recalls finding a Nelson’s Sparrow with Dave Anderson, a Dickcissel while searching for a Painted Bunting, and most recently a hatch-year female Black-throated Blue Warbler. Many of these birds are considered “ review list ” for Nevada. He shares updates through the WhatsApp groups and Facebook, helping others join in on sharing are bird sightings. For birders from across the state, Primm has become an unlikely meeting ground for the birding community. On a population scale, migrant traps like Primm may seem insignificant. But for individual birds, these patches of green can mean survival - a brief chance to rest, feed, and rebuild strength before continuing south. Every visit is a gamble with the possibility of reward, especially in April-early June and August to late October when most songbirds are migrating. Whether you’re in Primm, Corn Creek, Indian Springs, or a patch of trees in your neighborhood park, have a look and be open to the idea of finding something you wouldn’t expect. You never know what might drop in.
