July Birding Forecast

Monsoon season began in mid-June and will go until late September throughout the Mojave Desert. Monsoonal weather patterns are kicked off as warm, moist air is moved into the region by winds originating in the Pacific Ocean and the Gulf of California. When moisture builds and the conditions are right, thunderstorms and thick cumulus clouds begin to move through southern Nevada. Occasionally, the clouds will release water in the form of precipitation, providing the living organisms with much-needed moisture and cooler temperatures.


The pulses of moisture may stimulate insect activity and population growth. This in turn can increase bird activity. In wetter years, cicadas or grasshoppers can be abundant in the Las Vegas Valley. These large insects are important food sources for the many young birds in the area and can help them survive the most challenging parts of their lives: learning to find food without the help of their parents. You may see neighborhood mockingbirds and grackles feeding on grasshoppers, or roadrunners at larger parks chasing them with high levels of success.


Whether or not the monsoons materialize in July, the month tends to be hot and on the slower side throughout the Valley for birds and birders. However, there are bright spots for those willing to brave the heat. Many shorebirds may already be migrating through the area. Shorebirds are some of the first migratory birds to return to the area during southbound migration; their numbers will continue to grow through August and into September. The first birds may be plains breeders such Long-billed Curlews, Willets, and Wilson’s Phalaropes, followed by shorebirds from the boreal forests and Arctic tundra. They are often made up of adult birds that have not bred successfully and have begun moving towards wintering areas, followed by successfully-breeding adults, and later the young birds born and fledged this summer. Look for shorebirds at Henderson Bird Viewing Preserve, the Las Vegas Wash, and flooding lake beds.

Another interesting phenomenon is the movement of some species of waterbirds from Mexico into areas of the desert southwest. In July and August, the Las Vegas area may be graced by unusually occurring wading birds: White Ibis, Roseate Spoonbill, Reddish Egret, Little Blue Heron and Yellow-crowned Night-Heron are all species that could show up at wetlands. These are probably young birds born this summer that are dispersing, possibly following the Colorado River up from Mexico and into southern Nevada. It seems that at least one or two of these species will be turned up by birders during July and August.



Birders can escape the heat by heading into the Spring Mountains. By July, many of the high elevation birds have raised young, and breeding activity has slowed. Although birds are less vocal and active, they are still present in these habitats. It won’t be until August that most migratory birds from the Mojave and Great Basin mountain ranges begin to move down into the lowlands, where the risk of encountering high heat and less food, cover and water negates the advantages of getting any head start on southbound movements. The exceptions are hummingbirds; Rufous and occasionally Calliope Hummingbirds will turn up starting in late July at higher elevations. These birds leapfrog across mountain ranges in search of the late summer blooms of penstemon, goldenrod, thistle, and more.

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.
