For Large Day 2023, Workforce Sapsucker cut up into two teams and headed to far-flung components of the Pacific Flyway: Monterey County, California, and central Chile. Collectively the groups discovered an astounding 279 species. The group selected these two websites to spotlight the significance of the Pacific Flyway in supporting migratory birds and linking the pure historical past of North and South America.
The closing checklist encompasses an incredible showcase of avian range: warblers, orioles, and grosbeaks; tapaculos, rayaditos, and cinclodes; even albatrosses and penguins. The Lab is grateful to the numerous donors who supported Large Day, our greatest conservation fundraiser of the yr; and to LOWA Boots for sponsoring Workforce Sapsucker.
In Chile, A Patchwork of Wetland Preserves Pays Off
Workforce Sapsucker-Chile had their work minimize out for them. It’s properly into autumn, days are brief, and a lot of the migrants have already left—removed from an optimum Large Day time of yr. Fortuitously, two group members had been Chilean birders with intensive information: Sharon Montecino of the Chilean nonprofit Purple de Observadores de Vida y Silvestre de Chile (ROC), and Vicente Pantoja, a ROC volunteer and eBird coordinator for Chile. Rounding out the group had been Cornell Lab employees members Cullen Hanks, Jenna Curtis, and Tom Auer.
The group began at sunup, birding Laguna Batuco, an essential remnant wetland within the extremely developed Santiago space. Their first chicken was an entertaining Chimango Caracara. They went on to seek out 51 extra species at this cease, together with the nearly invisible Least Seedsnipe in addition to Andean Goose, for which the laguna is a winter stronghold.
Laguna Batuco is a remnant of a once-extensive wetland system that has slowly been encompassed by metropolitan Santiago, the Chilean capital, Hanks mentioned. It’s now one of many final remaining refuges for migrating and wintering birds in inland central Chile—and a spotlight of ROC’s conservation work.
In late morning the Chile group looped by dry foothills on their approach west, choosing up Chilean Tinamou, Chilean Pigeon, Chilean Flicker, and the charming Moustached Turca.
Then it was westward to discover the coast. They reached the Maipo River estuary, a crown jewel of Chile’s coastal wetlands, simply as low tide uncovered a sequence of mudflats that drew in foraging shorebirds. The group crested 100 species with birds like Rufous-chested Dotterel and Silver Teal. Additionally they added lingering long-distance migrants like Hudsonian Godwit and Whimbrel which are on their method to the Arctic.
By late afternoon they’d arrange scopes on the fringe of the Pacific, scanning chilly ocean waters for seabirds together with Black-browed Albatross, Peruvian Diving-Petrel, and Humboldt Penguin. With 121 species on their checklist, they knew they had been only one chicken away from the Might Large Day report for Chile. After which simply round sundown, as they had been negotiating visitors a Band-winged Nightjar flew up in entrance of the automotive: #122, tying the report. (After all, information are supposed to be damaged. That very same day, a group close to the Peruvian border, a thousand miles to the north, scored 134 species to set a brand new report.) At a port close to Valparaiso the group labored into the nighttime scanning flocks of Kelp Gulls for a brand new chicken, however ended the day at 122.
In California, Owls within the Morning, Hawks within the Night
Six thousand miles to the north, on the stroke of midnight, Workforce Sapsucker-California kicked issues off with a uncommon Noticed Owl. They went on to have a stellar owling session, including Nice Horned, Northern Pygmy, Northern Noticed-whet, Barn, Western Screech, and Burrowing Owls.
In a stroke of synchronicity, the group in Chile recorded their very own Burrowing Owl at Laguna Batuco at about the identical time. In all, the 2 groups discovered 18 species in frequent, together with resident birds like American Kestrel and Snowy Egret, in addition to long-distance migrants like Higher Yellowlegs, Black-bellied Plover, and Whimbrel.
By dawn the group—Brian Sullivan, Lizzy Chouinard, Brooke Keeney, and Whitney Mortimer—had been within the drier countryside southeast of the city of King Metropolis, the place they discovered species like Frequent Poorwill, Blue Grosbeak, Yellow-billed Magpie, Cassin’s Kingbird, Lewis’s Woodpecker, and Ash-throated Flycatcher (their a hundredth species of the day). By midafternoon they’d pushed again west to the Pacific to search for seabirds and shorebirds. At this level group chief Brian Sullivan thought 200 species may be potential, however dangerous luck was ready for them at Level Pinos, a famously good seawatching spot and a clutch level on their route.
After they arrived, thick summertime fog had enveloped the headland, knocking visibility right down to about 200 yards. It meant lacking species like Pink-footed and Sooty Shearwaters and Black-footed Albatross, and the group even needed to do with out Frequent Murre, Wandering Tattler, and Surfbird. They did choose up Pacific and Frequent Loons, Black Oystercatcher, and even a lingering rarity, Purple-footed Booby, perched on a yacht in Monterey Harbor.
On the plus aspect, the Californian Sapsuckers (not like the Chile group) had been on the receiving finish of migration. They discovered 8 species of warblers, 2 orioles, 2 grosbeaks, a few Olive-sided Flycatchers, and 13 species of shorebirds—together with a flock of 20 Whimbrels that will properly have been in Chile final month.
One of many day’s peak moments arrived (as they usually do in birding) on the municipal dump, the place Chouinard and Sullivan noticed a pair of Swainson’s Hawks in a courtship flight. (Swainson’s Hawks are uncommon in Monterey County and nests are even rarer.) Many Swainson’s Hawks spend their winters within the Pampas of Argentina—one other tangible reminder of the connectedness of South and North America. The California group completed with an astonishing 174 species for the day.
The Secret to A Large Large Day: Habitat
As Workforce Sapsucker prepped for his or her Large Day in Chile, they constructed their route round a key power: the intensive patchwork of small wetlands and guarded areas that ROC has helped create in recent times. By tuning in to habitat range, they made the a lot of the restricted chicken range readily available at this season.
To succeed in 120 species in autumn in central Chile, the traditional knowledge holds that you simply’d want to begin up within the Andes, Hanks mentioned—however you then’d want to seek out time to drive a few hours again right down to the lowlands. Workforce Sapsucker didn’t need to danger working out of daylight on the coast, so that they opted for a distinct technique.
“We didn’t get something completely spectacular [in terms of rarity]… we simply nailed all of the frequent, anticipated birds we wanted,” Curtis mentioned. Figuring out which habitats to hit helped all of it come collectively, because of the ROC teammates—Montecino labored extensively at Rio Maipo as a Coastal Options Fellow, and Pantoja is the coordinator of eBird for Chile.
“One factor we noticed scouting is that every of those [superficially similar] habitats had totally different birds,” Hanks mentioned. For instance, Rio Maipo was a cornerstone of the route that delivered 50 species, together with Coscoroba Swan. However to trace down a Black-necked Swan they needed to loop in a tiny wetland just a few miles to the north, in Cartagena—they had been nowhere else to be discovered.
When planning a Large Day “you study a lot about the place birds are and the place they aren’t,” Hanks mentioned. “In case your aim is to see as many birds as you possibly can, it actually forces you to consider habitat, and the way essential each little pocket of wetland is.”
It actually highlights the work ROC is doing to protect so many websites within the area, Curtis added. And by extension, it’s a nod of recognition for all of the individuals and organizations working to protect inexperienced area in cities and counties, up and down flyways and throughout continents. Each is a haven, a stopover website, a year-round house for a singular set of birds.

Congratulations to the group, and thanks once more to everybody who supported them!
