Birding

Barra de Potosi and the surrounding area offer wonderful opportunities for birders with a large variety of hard-to-find species. Your life list is almost guaranteed to get longer. Even if you are just casually interested in what you see flying around, you probably will want to get a copy of A Guide to the Common Birds of Ixtapa-Zihuatanejo, Barra de Potosi and Troncones. Copies are available at Enramda Teresita and Chiminiki’s store (on the right at the entrance to the village Barra de Potosi).

The best way to track down the feathered beauties is with a local guide. The easiest birding adventure is a boat tour either off shore or in the lagoon. Check the Boat Tour page for a list of boat guides and their contact information. The Laguna Potosi alone hosts over 100 bird species including the prized roseate spoonbill. An early morning kayak paddle into the mangroves is simply magical. A boat ride to Los Moros will yield boobies, pelicans, frigate birds and red-billed tropic birds. If you want to explore the the inland sites, a great starting point is El Refugio de Potosi described below. Further options are outlined in the book excerpt below.

In addition, every December 14th, a contingent of serious birders from the US and various parts of Mexico come here to participate in the Annual Audubon Christmas Bird Count. There is more info on this site under Various Stuff/Annual Events. If you are interested in participating, contact Laurel Patrick at laurel@elrefugiodepotosi.org.

Excerpt from Birding Guide

For an overview of the birding opportunities, this is an excerpt from a guide to birding in Guerrero–

Birding Guerrero, Mexico: The Ixtapa/Zihuatanejo Area
and the Sierra Madre del Sur

Barra de Potosi

Account by Nick Lethaby, just five visits to this site

Highlights: Herons, Red-billed Tropicbird, shorebirds incl. Collared Plover, Lesser
Ground-Cuckoo, kingfishers, hummingbirds
Missing: Most thorn forest species

A good and relatively close area for wetland species, seabirds, and hummingbirds is
Barra de Potosi, about 20 KM SE of Ixtapa. To get here, take the main highway (Route
200) south out of Zihuatanejo and turn right in the village of Los Achotes.

There are five main areas to consider birding here. There are hotels here and a great selection of seafood
restaurants, as well as a beautiful long beach. This is nice location for those who prefer to experience a more authentic Mexican vacation. The village of Barra de Potosi lies at the end of the road.

There is an annual Christmas Bird Count held here around Dec 14 each year, which offers a good way to meet other birders and learn what is around.

#1 ‘Gallinule Pond’ at Los Llanitos. As you drive from Los Achotes to Barra de Potosi, you will see a shallow pond on yourright about 2 KM from the turnoff from Route 200. This typically holds water until
around early spring and is a good location to stop. Northern Jacana and Common Gallinuleare here and there is usually a Purple Gallinule as well. Other birds include Sora, Black-bellied Whistling Duck, and White-faced Ibis.

#2 El Refugio de Potosi, founded by Laurel Patrick to increase awareness of the environment and local wildlife. El Refugio has exhibits featuring some of local wildlife species, including rehabilitated and injured individuals. El Refugio has fruit, seed, and hummingbird feeders as well as an artificial pond and stream that attract many of the local species. For details, visit the website at www.elrefugiodepotosi.org.

Currently El Refugio is closed to the public, but you can contact Laurel Patrick by email: laurel@elrefugiodepotosi.org for access by reservation. Laurel can also arrange access to Carrizo Lagoon.

The hummingbird feeders at El Refugio offer a good opportunity to see a number of the local
hummingbird species, although numbers can be very low in early winter (Nov-Dec) and occasionally throughout the winter:
Plain-capped Starthroat: This species is common from early April to late October or early November. Up to 50 can occur at the feeders at once. They are completely absent from November through March period both at the feeders and the rest of the Ixtapa area.
Cinnamon Hummers: Common year round at feeders.
Doubleday’s and Broad-billed Hummingbirds: Common year round but females are absent from approximately mid-June until about October. I believe I had males of both forms during an early April visit, as one bird was noticeably bluer (including forehead, crown, and underparts) but failed to verify whether it was also one of the birds that had white undertail coverts as at least two other males had. If both occur, the exact temporal distribution is currently unknown and should be studied by anyone visiting.
Green-breasted Mangos: Very uncommon but regular through from mid-August to mid-October, sometimes later. No more than 1-2 birds at the feeders at a time. Both males and females are seen though the males arrive first. Occasionally seen in about mid to late
April.
Green-fronted Hummingbird: Very uncommon but regular throughout the year with up to 3 at a time. This species is somewhat more regular during the dry months from November through April.
Golden-crowned Emerald: Very uncommon but regular throughout the year with up to 3 at a time. This species is somewhat more regular in the wet season.
Black-chinned and Ruby-throated Hummingbirds: Abundant from December through to the end of March. In my early April visit, the only males I saw were Ruby-throated so this species may linger later.

Other species regularly attracted to the fruit and seed feeders or to bathe and drink include West Mexican Chachalacas (very confiding here), Golden-Cheeked, Pale-Billed, and Lineated Woodpeckers, White Throated Magpie-Jay, Rufous-naped Wren, buntings, Yellow Grosbeak, and Yellow-winged Cacique. Lesser Ground-cuckoos are typically secretive but seen regularly either on the ground or in the lower bushes on the paths
(especially by the Heloderma) and around the little house.
The pond and stream are especially attractive to bathing and drinking birds towards the end of day bath when the recirculation pump has been turned off and there are little pools. Belted, Ringed, Green, and, very rarely, Amazon Kingfishers show up most days
around the pond or sometimes on the wires.

#3 Carrizo Lagoon

Immediately by the entrance to El Refugio de Potosi, a large freshwater lagoon known as Carrizo Lagoon is visible from the road (and also from the observation tower at El Refugio). This often holds large numbers of herons (including Boat-billed), Wood Stork, Roseate Spoonbill, White and White-faced Ibises, Anhinga, American White Pelican, ducks, shorebirds, and terns, depending on the water levels (highest in November and
then dropping lower into the spring, when good for shorebirds). This lagoon proved a good spot for kingfishers (Ringed, Green, and Amazon)and shorebirds, including a Collared Plover and several Northern Jacanas, on an early April visit. To get good looks at the birds, you need to walk down through the fields to access the lakeside. I did this and had no problems. Alternately, you can gain access to Carrizo Lagoon via El Refugio de Potosi, where a few kayaks and a canoe are available. To do so, contact Laurel Patrick laurel@elrefugiodepotosi.org

#4 Laguna de Potosi. This is a large shallow seasonally (Oct-Mar) intertidal lagoon that holds waders,
shorebirds, gulls, terns, and kingfishers. I have done hour long kayak trips twice and found them limited in effect due to the size of the lagoon and running aground in the shallows. However, you can see Ringed and Green Kingfishers and various waders (Bare-throated Tiger-Heronhas apparently been seen occasionally) this way. It might be better to try a boat up the lagoon although that will be limited by the shallow water as to how close it can get to the birds. If you are capable of enduring a long kayak session under the sun, you might enjoy more success. It is possible to drive or walk into the channels and mangroves areas on the N. side of the
lagoon (called Las Salinas) but I would not recommend this without a local guide and it is not possible to see very large concentrations of birds.

#5 Rocas de Potosi
These offshore rocks are also known simply as “Los Morros”. They are not visible directly from the village due to the headland but you can take a boat out to look around them. In 2017, the boat trip cost MX$1500. The boatman’s first name is Arturo and can be contacted by going to the restaurant called the Enramada Leticia in Potosi. The rocks have a huge (thousands) Brown Booby colony along with smaller numbers (many dozens) of Red-billed Tropic birds, Bridled Terns, and Brown Noddies.The terns are generally not present until into April. At least in winter, careful checking of the boobies should reveal a few Masked and Blue-footed Boobies. I saw both of these on my December trip, along with many displaying tropic birds.
