A Field Guides Birding Tours Report
Gulf of California: Mexico's Rich Desert Coast 2022
December 5-10, 2022 with Micah Riegner & Tom Johnson guiding
This was our second run of this brief but jam-packed tour on the Gulf of California. We kicked off our adventure in Hermosillo where we spent our first afternoon at Parque Metropolitano watching a pair of ultra-cooperative Bendire’s Thrashers and numerous waterbirds under a cool, overcast sky. Soras seemed to call from every clump of vegetation, and we even saw Virginia Rail dart through a gap in the reeds, a rarity for the Hermosillo area. The next morning found us at San Miguel de Horcacitas, a picturesque old Mexican town backdropped by an impressive Organpipe-covered canyon above a lush desert riparian area. Carlos, my longtime birding pal from Hermosillo joined us that morning to show us around his “birding patch.” Highlights from the morning included the close Green Kingfisher sitting quietly above the water, the group of Elegant Quail that eventually showed nicely and the Nutting’s and Ash-throated Flycatchers, which allowed us to take in their subtle field marks. The Five-striped Sparrow, Sinaloa Wren and the Black-capped Gnatcatchers in the Mesquites were icing on the cake.
We then took off to Kino Bay, where we spent the rest of the week birding mangrove-lined esteros, offshore islands and desert hillsides, between bouts of fish tacos, hot tamales, pozole and fresh flour tortillas. Our offshore islands boat trip took us to the southern end of Isla Tiburon, the Cardon-packed Isla Cholludo and Isla Datil where we saw California Sea Lions, Brandt’s Cormorants, roosting Blue-footed Boobies, Red-billed Tropicbirds and rafts of Pacific Loons. We then ventured into deeper water south of Isla San Esteban where we encountered numerous Craveri’s Murrelets, most of which were already paired up. These tiny alcids nest on the many islands in the Gulf of California. They’ll find a rock crevice just above the high tide line where they’ll plop two eggs. Shortly after hatching the cotton ball chicks take to the water where they continue to get fed by the adults. Other highlights from that boat day were the Bottlenose and Long-beaked Common Dolphins, the raft of Red Phalaropes pecking at the water’s surface and the expansive vistas of uninhabited desert islands.
Our next boat trip was up the Infernillo Canal, the turquoise waterway between Isla Tiburon and mainland Sonora. We met Cosme, the boat captain at the Comcaac village of Punta Chueca and were joined by Luis a local Comcaac guide. Every year thousands of Redheads congregate in the Infernillo to feed on the eelgrass that grows in the shallow water, and this year was no exception. We saw huge flocks whirl past our panga, backdropped by the rugged Isla Tiburon. We also saw a handful of Brant (the bulk of the wintering population had yet to arrive), Surf Scoters and a Horned Grebe tucked in with a flock of Eared Grebes. After a field lunch, we drove back to Punta Chueca, said goodbye to Cosme, and drove to Estero Santa Rosa where we scoped a Ridgway’s Rail among the mangrove proproots.
Our final day we birded Estero Santa Cruz, the huge expanse of mud and mangroves just south of Kino Bay. At our first stop we saw Mangrove Warbler, Northern Waterthrush, some White Ibis and Marbled Godwits. We then drove to the other side of the estuary where we scoped several hundred Western Sandpipers with Semipalmated and Snowy Plovers on the shimmering mudflats. Gull-billed Terns performed their routine swoops to pick off unsuspecting fiddler crabs. We then drove around to the mouth of the estuary and compared Royal and Elegant Terns, with a Common Tern and Bonaparte’s Gull mixed in the flock. Right before we had to leave, Tom spotted a Lesser Black-backed Gull in a line of Yellow-footed Gulls—way to go Tom!
We wrapped up the tour with a sunset visit to the Cardon forest outside of Kino Bay and marveled at the colossal cacti. They were so big they made the Gilded Flickers look like hummingbirds! Numerous people deserve credit for the success of this tour. We’d like to thank Carlos for sharing San Miguel de Horcacitas with us, Greg, Ana, and Nicole in our office for all the travel arrangements, captain Cosme for great times out on the water and Hector for sharing his passion for marine mammals. Finally, we need to thank Vickey for those five-star field lunches and that delicious pozole she made for us our final afternoon together. I wish I could have taken some home! Tom and I would like to thank you all for joining us on the Gulf—we had a blast and look forward to birding with you again soon!
