A Field Guides Birding Tours Report

Gulf of California: Mexico's Rich Desert Coast 2023

December 4-9, 2023 with Micah Riegner guiding
Field Guides Birding Tours
This is THE best tour we offer to see Craveri's Murrelet. On our boat trip south of Isla Tiburon we saw close to 80 individuals, most of which were paired up. Soon they will find a crevice on one of the islands to lay their eggs. Upon hatching, the fluffy chicks will immediately head to the water where they will be fed by the parents until they are independent. Photo by Micah Riegner.

I've been going to Kino Bay since I took my first steps there, so it’s always nice to return and relish those childhood memories of birding the estuaries, going out on the pangas and seeing seabirds and marine mammals, eating fresh tortillas and watching vivid orange sunsets from the beach. This trip brought back those memories and, sadly, memories of Tom Johnson, who co-led the tour with me only last year. I still can’t believe he’s gone...

Our first afternoon after touchdown in Hermosillo, we birded Parque Metropolitano seeing good numbers of waterbirds, lots of Yellow-headed Blackbirds, a Virginia Rail and Bendire’s Thrasher. The next morning, we drove to the sleepy town of San Miguel de Horcasitas and birded the riparian area along the Rio San Miguel. It was good to see a decent amount of water in the river. We crisscrossed the river, finding Black-capped Gnatcatchers, a male Streak-backed Oriole, both Happy and Sinaloa Wrens, several Green Kingfishers and last but not least, Elegant Quail. They were mixed in with a covey of Gambel’s Quail, about 8 of each.

From Horcasitas we returned to Hermosillo, packed up and left for Kino Bay. We made a brief stop at Estero La Cruz where we scoped several Snowy and Wilson’s Plovers on the mudflats. The following days in Kino we continued to bird the Estero, finding swarms of overwintering Western Sandpipers, a Ridgway’s Rail that swam across a shallow pool, a gorgeous male Mangrove Warbler and numerous herons, including Reddish Egrets dancing in the shallows. During our desert forays we found overwintering Gray Vireos in the hillsides covered with fruiting Elephant Trees, lots of Ash-throated Flycatchers, a Cassin’s Sparrow and, my favorite, a Ferruginous Pygmy-owl. In all the years of visiting I’ve never seen it there. Special thanks to Fiona Reid who told me about it after her visit here a couple weeks ago.

During our week in Kino we had nice calm weather to take two boat trips, one up the Infernillo Canal and one offshore to the deep water south of Isla Tiburon. For our Infernillo trip we were joined by Jaime and Lauren, who conducted a Brant Survey, tallying upwards of 1580 individuals that day. We also saw hundreds of Redheads and, to my surprise, several hundred Surf Scoters, a dramatic increase from last year. A pod of Bottlenose Dolphins encircled our boat giving us great views. The next day we left for deeper water to the south of Isla Tiburon where we found flocks of Black-vented Shearwaters streaming south toward Isla San Pedro Martir, close to 80 Craveri’s Murrelets and a last-minute Red-billed Tropicbird. We encircled both Isla Cholludo and Isla Alcatraz and saw Blue-footed Boobies on the cliffs, good numbers of Brandt’s Cormorants and a pair of Common Goldeneye.

Our final morning before we left for the airport we had the rare opportunity to see baby Olive Ridley Sea Turtles hatching from their nest. Cosme, the boat captain for Prescott College, runs a turtle monitoring program and keeps close tabs on nesting turtles, so he knew exactly when they’d be hatching. What a wonderful way to wrap up our time in Kino, watching those tiny turtles squirm out of the sand! I wish them the best of luck out there in the open ocean. There were lots of people who played a role in this tour. First, I’d like to thank Nicole in our office for all the arrangements, Cosme for his expert captaining of the panga, Lauren, Jaime, Luis and Ulises for sharing the work that they do, Holly and Ana for their station orientation and Vickey for her great Sonoran lunches. I’d like to thank you all for joining us on this coastal desert adventure and I look forward to seeing you again soon!
