26 January - 22 February 1999
by Jon Hornbuckle
I undertook a Mexico "clean-up" trip, excluding the northeast, having already briefly covered Yucatan and Sierra de Atoyac, plus Guatemala. This followed 10 days in Cuba and so started in Merida, for the three coastal endemics, before proceeding to Oaxaca, southern Chiapas, Jalisco and Colima, San Blas, southern Baja (mainly for whales), and the Mazatlan area. For part of the time I was accompanied by Ashley Banwell. The trip was quite successful except in Chiapas where we were unlucky with the owls and chose a degraded locality in the morning, exacerbated by too little time. With few birds singing, it was harder work than I had hoped - 58 ticks but I failed to find any of the most difficult species such as Aztec Thrush, Eared Trogon or Thick-billed Parrot. Relied on birding reports, Brian Gee's being especially useful, until Oaxaca when obtained Steve Howell's Bird-finding Guide to Mexico which made life a bit easier.
International flights were trouble-free with American Airlines, courtesy of Airmiles; internal flights with Mexicana and Aero California were OK but quite expensive and invariably delayed by an hour or so. All 4 hire-cars were VW beetles, an excellent vehicle for the bumpy roads. Only problems were inability to undo tight wheel nuts when we had the one puncture (up Volcan de Fuego) and spare wheel stolen from inadvertently unlocked boot/ trunk. Various international companies were used but prices were similar at around $50 a day including insurance and tax - the main variable was insurance cost which could range from $7 to $19 a day, depending on company and amount of cover. All other costs were low, with hotels and meals only a few dollars a time, except for road tolls (eg $8 Colima-Manzanillo) - and whale-watching: $40 per boat hour (6 max passengers). I found most Mexicans to be friendly, helpful and honest but there are a few rogues about, such as the Mexicana check-in clerk at Merida who insisted we had not paid tax on our tickets, despite (correct) protestations that we had, and the nice man who would not unlock the chain across the logging road at Cerro San Filipe without payment of $7 for the third day running.

COMMENTS ON SITES
I visited Merida, Chiapas and southern Oaxaca before obtaining a copy of Howell's indispensable site guide. The following notes are personal experiences.
Merida
We saw the 3 coastal endemics early in the morning c3km beyond Chicxulub. There is a broad track between the main road and the sea just after a new development called Josefina, before a small café on the inland side, which leads to a line of red brick houses with blue roofs. The wren and the sheartail were visible from the track and the bobwhite found by tramping about in the open scrub. Contrary to what Howell says, Ashley saw only the sheartail during an afternoon visit earlier; he also saw Rufous-necked Wood-Rail in the mangroves south of Progreso.
Oaxaca
Well covered by Howell, although the sp. lists seem a bit optimistic for the winter period.
Dick Byrne's trail at Km 203.5 leading from the picnic spot on right after Black Tank was good - leave the "car park" away from Oaxaca, down to the concrete bridge over the river and continue up into the pines - did not see his Dwarf Vireos but Ocellated Thrasher gave good views.
El Porvenir was disappointing, with no White-throated Jays. We found Blue-capped Hummingbird at Km 188.7, having failed at Pluma Hidalgo. There is a bumpy but drivable track on the left when going towards Oaxaca, opposite a more obvious track going up into shade coffee. A pair of the hummers was at the first bend by a small canyon.
A random stop on the way back from Tehuantepec to Oaxaca to check the thorn forest in the foothills, at Km 244, 8+km west of Tehuantepec, gave the elusive West Mexican Chachalaca - along a trail on the left.
Hierve el Agua is a spectacular, arid site but not particularly recommended for birds. Yagul is key for Grey-breasted Woodpecker and Beautiful Hummingbird on the tall cacti.
Chiapas
Huitapec NR can be found without going into San Cristobal - a difficult town to drive in. From Tuxtla, do not turn right into town but carry on till you meet the signed left turn to Chamula and the reserve is c4km along this road. It is possible to get in, as the locals do, even when the large gate is locked, but it is useful to have the local guide Roberto at night for the owls. If no-one is there, just wait a while and they will find you. We were unlucky, not helped by the full moon, as we were unable to see the calling owls which stayed in thick canopy. The camp site area east of San Cristobal was badly hacked and disappointing; must be better to follow Howell's directions but notethat further afield around San Cristobal is potentially dangerous due to insurgents.
Tuxtla Gutierrez zoo, not mentioned by Howell, is worth a visit for the habituated but wild Great Currasows and Crested Guan. It is on the outskirts of town by the main San Cristobal road.
Sumidero Canyon proved almost birdless in the afternoon but was good all the following morning. At the entrance gate we were told the first and third miradors were dangerous, presumably due to thieves, so did not visit the first but the trail to the third was one of the most productive areas. The only Belted Flycatcher and Fan-tailed Warbler were on a small trail on the left c500+m back down the road from the third mirador.
Attempts to find Giant Wren with little time and gen were frustrating but eventually succeeded outside Pto Arista. Leaving the town northwards, cross the big river/ canal and turn right at the first cross-roads. A pair of wrens responded to tape in the field with scattered bushes on the left. Had a flock of Paciffic Parakeets 3km north of Arriaga.
Colima & Jalisco
Followed Howell but skipped the Autlan area. Driving from Guadalajara to Cd Guzman, took a track to the left just south of Laguna Sayula to check the fields and ponds - quite rewarding. Able to drive up to Km 21 on Volcan de Fuego, stopping before dawn to try for Eared Poorwill without success. Found Km 18.5 and 12 the most productive, with Colima Warbler, Bumblebee Hummingbird and Shrike-Vireo. The following morning the dusty lower region gave some gems including Spotted Wren, Dwarf Vireo and Lucifer Hummingbird.
A late afternoon visit to La Cumbre from Colima gave the two owls c.500m below the top, at 19.00 just before dusk, by use of canned tape, and Buff-collared Nightjar on the way down. No sign of Lesser Roadrunner but later learnt that Bostock et al had seen it well near the track off to the right c1km before the top. On the way there, saw Black-chested Sparrow near the start of Piscila Road.
Playa de Oro Road disappointing even though there just after dawn - no Flammulated Flycatcher or Rosy Thrush-Tanager - Barra de Navidad a pleasant town. Headed west to hills some 10km away and took a trail on the right after breasting the highest point - a good flock included only Red-breasted Chat of the trip. Nearby Barranca El Choncho well worthwhile - Maroon-fronted Parrot, San Blas Jay - but still no Flammulated Flycatcher and failed to see the calling Hermits in large trees at the start, despite some effort - expected to catch up with this sp. at San Blas but unfortunately did not. Finally caught up with Flamm Fly at the last gasp - a speculative stop at Km 18.3 from Barra; walked 200m down a track on the right and played the tape for the last time - amazed to get a response - a small Myiarchus-lookalike scolding from above, definitely the boy!
San Blas
Saw outstanding species fairly easily here except Elegant Quail, Lesser Roadrunner, Grayson's Thrush, Rosy Thrush-tanager, Sparkling-tailed Woodstar and the Hermit. Purplish-backed Jays feeding on fallen palm fruits on San Blas Jay Road (see Where to find birds in San Blas by R. Novick and Lan Sing Wu) was a highlight. Spent a lot of time in the Huaristemba area, with only frustratingly brief view of quails, and saw many Rufous-backed Thrushes but could not string Grayson's. Intended to take an afternoon ferry to Peso Is for the quail but found it impossible to get there except in the morning.
The pelagic in a small motor boat, arranged by Neil Bostock et al, was disappointing for birds but gave great views of a whale-shark, my most wanted fish, and some spectacular leaping displays by Manta rays.
El Cora Road was a waste of time, almost totally deforested, but Cerro de San Juan, near Tepic, was rewarding, especially for the hummingbirds - found mainly in the numerous blue flowers at Km 10.7, the first canyon in the humid forest - Mexican Woodnymph, Bumblebee Hummingbird and Dickey's Oriole.
Baja
Surprisingly few birders seem to have visited southern Baja and no-one I approached knew anything about whale-watching at what is reputed to be one of the world's best sites. There are 3 traditional endemics here, plus California Gnatcatcher and Grey Vireo, both difficult in western USA, while further north is the new endemic split off Le Conte's Thrasher; Howell and Webb have split a further 3 species occurring in the mountains near the southern tip - Cape Pygmy-Owl, San Lucas Robin and Baird's Junco.
Although the ferry, eg to or from Mazatlan, had its attraction, eventually decided to fly to save time and hassle - obtaining tickets is not straightforward and the trip takes nearly 20 hours. Collected car pre-booked with Dollar at La Paz airport and soon heading north to Cd Constitucion - all main roads here are in good condition. Good desert scrub along the road for many miles; soon stopped, just north of the check-point beyond habitation - Grey Thrasher and California Gnatcatcher. Changed dollars at Cd Constitucion then turned west to Pto San Carlos where on arrival Grey Whales could easily be seen blowing in the bay. No shortage of boatmen offering morning trips - arranged to go out with 4 Americans. Preferred starting time appears to be 08.00 but probably better to go earlier because the only breaching observed was early on and wind got up by about 10.00. Excellent views of possibly 50 Grey Whales scattered throughout the large bay (said to be 200 present), some swimming directly under the small boat, but it was rare for more than their backs and possibly tails to come out of the water. Suspect January might be a better month, with more display. Other species, eg Humpbacks and Blues, occur in the Sea of Cortez but it appears to be necessary to take a cruise to see these.
After this it was a long drive down to the southern tip to look for the other endemics. The difficult bird is Belding's Yellowthroat as it occurs in reeds, which are pretty scarce in Baja. Howell gives directions to San Jose Estero, where I finally scored with one on the opposite side of the river to El Presidente Hotel, after perusing dozens of yellowthroats, all of which seemed to be Common. It would doubtless be easier in the breeding season. Xantus' Hummingbird and Grey Vireo proved to be surprisingly scarce but I eventually found both along the old road back to La Paz, 3-4 km before San Antonio: took a wide gated track on the left for 200m to an open area with a few cattle and birded the thorn scrub round the edge of the clearing. Also saw the hummer at Boca de la Sierra, as recommended by Howell. Tried to find way into mountains without undertaking major trek per Howell - Agua Caliente, a beauty spot inhabited by ageing hippies, looked promising but I could not find any trails into the nearby hills, so won't be accepting the Howell splits. The pleasant hotel at nearby Santiago saved having to overnight in a large resort.
Mazatlan
Tried all Howell's Durango Highway sites up to Barranca Rancho Liebre (BRL) but the only one that looked promising was the road at Km 285, near start of the highway. The biggest stroke of luck was when at 06.45 a couple of jays flew across the road at Km 206.5 en route to BRL.. This proved an excellent stop, giving close studies of Tufted Jay, Rufous-capped Brush-Finch (which had eluded me in Oaxaca and Colima) and Red-headed Tanager. After this BRL was an anti-climax, with no ticks, although a pleasant enough spot. A short stop at Km206.5 on the way back produced nothing. The cheap motel mentioned by Howell is Motel Vadira at Potrerillos, close to Panuco Road - quite acceptable, with a modest restaurant La Pasadita opposite - probably not as pleasant as the German hotel lower down but more convenient.
La Noria Road, my final destination, was a great success. The bus goes from near but not in, the main bus terminal - precise location and timing varied with every person asked - 06.00, 06.30, 07.00 all quoted but it actually appeared at 06.40 and left 5 mins later - an infrequent service. I alighted 3km down La Noria Road, at the first track off to the right. Spent the morning on the left, in the fields and along tracks through the thorn forest, before walking the 3 km back to the main road where buses are reasonably frequent. Highlights were good views of Elegant Quail, Lesser Roadrunner and Five-striped Sparrow, an excellent end to the trip!

SYSTEMATIC LIST
Taxonomy, names and sequence are based
on Birds of the World: A Checklist by JF Clements (1991), with Howell
and Webb splits incorporated. Concentrating on the endemics, I failed to
record or indeed identify many of the North American migrants, especially
flycatchers and vireos, and did not try to see some species already seen,
eg Rufous-necked Wood-Rail, Boat-billed Heron, Common Potoo, Mountain Pygmy-Owl.
