Flight from Newark to Mexico City; arrived
10:30 pm. The "24-hour" National Car Rental Office at the airport shut tight.
Overnight in Hotel Riazar, a 15-20' taxi ride from the airport.
Saturday, March 23
After some delays and problems with the car rental, we leave for Oaxaca via toll roads (convenient but expensive: $25 for 450 km). On a very deserted desert/mountain stretch of highway on Route 190 south to Oaxaca, the car overheats; there is no water in the radiator. We add water and antifreeze and try not to push too hard up the many inclines, but the car continues to overheat and lose water. Fortunately, there are call boxes nearby and the highway patrol comes to the rescue with water and a wrench to fix a loose clamp on a radiator hose pipe which has apparently been leaking water for some time. Curiously enough, in the midafternoon heat in this dry, searing, multi-cactus, desert-like environment, there are many birds. While waiting for the engine to cool off or the road patrol to arrive, we find Russet-crowned Motmot, Grey-breasted Woodpeckers, Rock Wren and other specialists of this semi-desert habitat.
Due to these problems, we arrive in Oaxaca
too late to do any further birding. We stay in the Motel Columbia, one of
the "love motels" on Route 175 just north of town, on the way to Garbage Gulch
and La Cumbre (Cerro S Filipe) and not far from the junction with Rt 190
(which leads to other local birding sites such as Teotitlan and Yagul).
Sunday, March 24
Good morning birding at the so-called "Garbage Gulch" which is north on Route 175 between km markers 206 and 207 (both endemic sparrows, Pileated Flycatcher, etc.). Afterwards we drive up to La Cumbre at km 192 and take the western (left-hand) dirt road onto the Cerro San Filipe ridge. The local guardians are now extracting 50 pesos per visit and make everyone sign in (hopefully helping to control the woodcutting that is endemic in this area). We follow this dirt road c. 9 or 10 kilometers before turning back. Birding here remained quite good well into the afternoon and included a flock of the Dwarf Jays with Gray-barred Wrens at c. 3 pm. An evening stop at "Garbage Gulch" on the way down was less productive.
Comet Hyakutake is visible from the courtyard
of the motel as a fuzzball in the northwestern sky; it should be at or close
to its peak of nearness and brightness.
Monday, March 25
This morning we venture south to Rt 190 and turn left, heading eastward to Teotitlan del Valle where we again turn left, go through the village, check out a reservoir beyond and then continue up the mountain, birding the desert-like scrub lower down and the pine forest edge higher up. This was very productive in its lower reaches, notably for Dwarf Vireo but also for Lesser Roadrunner, Boucard's Wren, Blue Mockingbird, Blue-hooded Euphonia and desert-type hummers (plus a few waterbirds at the reservoir).
Late morning and midday in the desert scrub
at Yagul (Gray-breasted Woodpecker, Boucard's Wren, hummers; also nesting
Ravens and an unexpected and out of range Pyrrhuloxia). Late afternoon, back
up to La Cumbre and a less productive visit to the eastern (right-hand) dirt
road. No one was present to collect 50 pesos but, on the other hand, we didn't
see very many birds.
Tuesday, March 26
A frustrating morning at Monte Alban trying to raise up the Slaty Vireo which responds to the tape but refuses to come in. A singing thrasher proves to be Curve-billed not Ocellated (this will happen to us again). Other birds include the Blue Mockingbird, a Pileated Flycatcher with its crest down and several hummers.
Most of the rest of the day is spent driving
to Puerto Angel with birding stops in pine-oak and cloud forest in the Sierra
de Miahuatlan. The Blue-capped Hummer is at La Soledad exactly where Steve
Howell said it should be (this is the area of the type specimen of this Red
Data Book bird)! The spot -- a trail on the eastern side of the road just
before the village of La Soledad -- was surprisingly birdy in the mid-afternoon.
Arrival at Puerto Angel after dark. Stayed in the Huespedes Capy.
Wednesday, March 27
Good morning birding in a stream bed track which penetrates quite deeply into the thorn forest near Puerto Angel. This track begins as an obvious dirt road exactly at the end of the village of Zipolite, a kilometer or two beyond Puerto Angel (there is a sign facing the other way that says Zipolite (not Playa Zipolite) and a bridge also marks the spot which is opposite a nursery school that looks like a coconut plantation). The lower reaches of this stream bed/trail are populated with homesteads and there are several side paths leading in and around areas of the stream bed that are presumably wet some part of the year; but eventually all the side paths seem to come back to the stream bed itself which is periodically covered with big jumbles of boulders and rocks and contained a few remaining pools of water.
Torrents must come rushing down this ravine from time to time and I would be wary during rainy season or if there were a cloud burst. Although unpromising looking, this proved to be one of the birdiest areas we found and it was birdy almost all the way, from early morning to midday, with active leks of Citreoline Trogons, Golden-cheeked Woodpecker, Orange-breasted Bunting and many other birds. On our return, in the heat of the day, a wait by the rocks and pools proved very productive as birds came in to drink and bathe.
We spent the extremely hot afternoon in one of the many beach palapas in the next village after Zipolite, imbibing cold drinks, eating octopus ceviche and watching leaping, cavorting Humpback Whales with a few, mostly distant, sea birds for variety.
A return to the ravine at dusk produced one
delayed bit of excitement: an improbable tinamou call that was later diagnosed
(via tape) as a Pheasant Cuckoo, the closest we were to come to this fabled
creature.
Thursday, March 28
Morning back up in the Sierra de Miahuatlan
at the Pluma Hidalgo Road (km marker 196; very active: Gray-crowned Woodpecker,
Emerald Toucanets, flocks of migrant warblers, buntings and grosbeaks) and,
afterwards, at La Soledad. Afternoon drive south on Route 200 to Tehuantepec
with roadside stops at a coastal pond and lagoon where we find birds and birders
(2 American women who, with a Brit at Palenque, were the only other birders
encountered on the trip). Stayed in Tehuantepec at the Hotel Oasis.
Friday, March 29
Early morning we backtrack 8 kilometers on Route 190 toward Oaxaca in thorn scrub for Sumichrast's Sparrow and a few other birds of this semi-desert habitat (West Mexican Chachalacas, desert-type hummers including the endemic Doubleday's, a Howell & Webb split). In addition to the birds, we also see two Tayras, a large Mexican weasel active in the daytime.
Midday drive east to La Ventosa on the Isthmus of Tehuantepec where we find the road is blocked or blockaded, apparently by a political action. We backtrack to Juchitan and head north toward Ixtepec just short of which we find an interesting bypass, a dirt road that follows a canal and offers some good birding (including Crane Hawk and easier Sumichrast's Sparrows than the Route 190 site). Eventually both road and canal intersect with Route 185 which cuts across the Isthmus. We take this north some 24 kilometers past Matias Romero and then proceed northeast for 40 kilometers on a dirt road to an area of limestone cliffs, reputed to be the only drive-up site for Nava's Wren.
There is a bridge crossing a beautiful river lined with limestone cliffs and, before the bridge, some patches of good Atlantic-slope rainforest; one accessible patch is less than 1 kilometer before the bridge on the northwest side of the road. Unfortunately, a local truck driver crossing the bridge stops to warn us that the area is very dangerous and, as can be imagined, this takes the edge off of our explorations of this very birdy forest. As it is now well into the afternoon and we are all concerned about the warning we have received, we reluctantly abandon the area without finding the wren and it takes us the rest of the remaining daylight to regain the highway where we find a decent roadside motel. (The Brit we met at Palenque told us that he climbed higher and further on the same limestone/forest trail and found the wren.)
Two footnotes to the Nava's Wren run. (1)
We hear later that the danger here is not political but drug-running. (2)
The detour was not entirely a loss since, in addition to rain forest birds
at the Nava's Wren site, we also saw a Yellow-headed Parrot on the way in;
this well-known species is also a Red Data Book bird because of excessive
trapping for the pet trade!
Saturday, March 30
Coming back down the Isthmus at dawn on Route
185, we turn left at the eastern continuation of the aforementioned canal
road for some good early birding (Crane Hawk again) and, 9 km further, join
up with Rt 200 (the coastal road) via a sharp right turn at the closest approach
to the highway (easily visible on the right). We bird the foothills of Tapanatepec
in Chiapas at midday for Rosita's Bunting (which we find) and then drive
to Arriaga and Puerto Arista where we bird the lagoon and mudflats at Boca
del Cielo (with an astonishing Buff-breasted Sandpiper!) and the mangrove
lagoon and adjacent fields on a dirt road just to the northwest of Puerto
Arista. The fields here are full of large numbers of (preumably migrating)
Scissor-tailed Flycatchers and Dickcissels. We have trouble finding decent,
inexpensive rooms at Puerto Arista -- it is a popular spot for Mexican families
on Holy Week holiday -- so we backtrack to Arriaga for the night.
Sunday, March 31
We return at first light to the junction of
the Boca del Cielo road just north of Puerto Arista where we find duetting
Giant Wrens almost immediately. We also bird the dirt road that skirts the
mangrove lagoon to the west finding, among other things, Citreoline Trogon,
Russet-crowned Motmot and Gray-crowned Yellowthroat. Afternoon to Mapastepec.
After finding rooms in town at the Bosque Hotel, we try the road to Guadalupe
Victoria (the usual starting point for camping trips on the El Triunfo volcano).
The road is passable in our rental vehicle for only part of the way but,
in spite of the heat, we find good birding along the stream that parallels
the road (Pigmy Kingfisher, Turquoise-browed Motmot, hummers). Heading further
south, we turn off to the town of Escuintla and thence to the village of
El Triunfo from where we are able to walk up a distance into coffee plantation/cloud
forest habitat.
Monday, April 1
Morning in the Mapastepec Microwave Valley.
The road to the towers is completely denuded and holds nothing but the road
in the ravine below is productive (White-bellied Chachalaca, Prevost's Ground-Sparrow).
Drive to Arriaga in the late morning, birding the foothills on the way up
to Tuxtla Gutierrez (again finding Rosita's Bunting). Sumidero Canyon in
the afternoon is quiet except for a few interesting hummers. Arrival in San
Cristobal after dark and overnight in the Hotel San Martin.
Tuesday, April 2
Good early morning birding in a ravine on the eastern edge of town (Yellowish Flycatcher, Black-capped Swallows, Rufous-collared Thrushes). Afterwards to the Ocosingo Road where, after a frustrating couple of hours combing the higher reaches of a pine forest, we find Pink-headed Warblers almost by the road (and at eye level in scrub openings, not in the pines at all). This locality can be reached as follows: 2 kilometers from the beginning of the Ocosingo Road there is an obvious track on the right going back (almost parallel to the road) into the pine forest; instead of taking this track, look for an open grassy area on the left and another track, not immediately visible from the road, heading up onto the same forested slope; this second track is marked by a succession of openings in the forest (where wood has been cut) grown up to scrub; it is in one of these openings, in the scrub (try the third patch or so) that the warbler is to be found.
We now head towards Palenque but after 30
kilometers or so, we find the road blocked, apparently by Zapatistas, and
we are forced to turn around and return to San Cristobal. Since it is still
relatively early, we bird the Pronatura Reserve just northwest of town. This
is a remnant piece of cloud forest with a few birds on top but the best birding
is by a little stream just back of the entrance (Blue-and-White Mockingbird,
White-naped Brushfinch). Overnight in the Hotel Fra Bartolomeo de las Casas
(the Hotel San Martin being full).
Wednesday, April 3
We decide to take the longer, more westerly
route to Palenque, doing a bit of roadside birding on our way out. After missing
the turn to Villahermosa and almost going back into Tuxtla, we find the right
road, passing through an attractive forested mountain area before descending
to the Caribbean lowlands and south to Palenque; the trip takes us a good
8 hours. Evening birding at the base of the ruins (Rufous-tailed Jacamar)
and on a nearby stream (Lesser Yellow-headed Vulture, probable Ridgway's
Rough-winged Swallows). On our way back to Palenque village -- we are staying
in La CaSEada just outside of the village -- we observe the eclipse of the
moon.
Thursday, April 4
Although Palenque is not open to the public
before 8 am, we manage to talk our way into the ruins area at first light
(we have a letter in Spanish from Julio de la Torre, president of the Linnaean
Society and that helps a lot) and we bird our way through the main area of
ruins and up the forest trail that climbs the ravine by a stream behind the
ruins. This steep path was very birdy (Mexican Antthrush, Scaly-throated Leaftosser,
Green Shrike-Vireo; heard Greater and Slaty-breasted Tinamous). Evening on
lower trail just below the ruins.
Friday, April 5
ES hears an owl before dawn just back of our cabin and manages to put a light on it, getting a somewhat shaky look (shaky because he is holding the light in one hand and the binoculars in the other). Without checking, he misidentifies this bird as a screech owl but it is, in fact, the Mottled Owl which is smaller than he remembers it.
Early morning on lower trail; less productive but Montezuma Oropendola, Bright-rumped Attila, Long-tailed Hermit, etc. Late morning on upper trail.
Afternoon drive to Tuxtepec through the humid
Atlantic lowlands (Black-collared Hawk seen from car) takes us 6 hours. Night
in Tuxtepec.
Saturday, April 6
Early morning on the forest slopes above the
village of Valle Nacional. After a strong start (Rusty Sparrow, a pair of
hunting Common Black Hawks), most of the rest of our time in this gorgeous,
rich and flowery forest is socked in and relatively few birds are actually
seen. Eventually we cross over to the dry side, out of the mist and drizzle.
After a few modestly successful birding stops (we finally find Collared Towhees),
we climb up again and cross our path at La Cumbre, descending to Garbage
Gulch where, at the last possible moment, we pull in the heretofore elusive
Slaty Vireo. Overnight in another of the Rt 175 love motels.
Sunday, April 7
A last return to the east road at La Cumbre/Cerro S Filipe and a much disputed woodcreeper. We drive almost 20 kilometers looking for a mythical logging camp, seeing the Dwarf Jays again and also several Collared Towhees which we missed on our earlier visits. This is the locality where Sibley found the Collared and Spotted Towhees in sympatry without any evidence of interbreeding -- i.e. behaving like good species -- and he had specifically asked us to look for them here (it would have been embarrassing not to have found them!). It was also interesting to note that the Collared Towhees were in the brush under pines while the Spotted were in an oak/deciduous or cloud forest type of habitat.
Afterwards, we return to the highway for the
long 7-hour drive north and west toward Mexico City, spending the night in
the Auto Motel Villa Tlalmanalco, another "love motel" in Tlalmanalco/Amecameca
on the slopes of the twin volcanoes that guard the valley just outside the
Mexican capital.
Monday, April 8
Our plan is to bird the Amecameca Road just below Popacatapetl but the fates are against us. In the morning, the car battery is completely dead. We get a jump start and get as far as a forest patch that is teeming with birds. This relatively brief stop produces perhaps 1/8 of the total number of species of the entire trip. An interesting feature of the bird life here are the Olive-backed Towhees, part of a long hybrid cline between the Collared and Spotted Towhees. So we have seen two extremes of the interaction between these two forms. Other birds of interest include Buff-breasted Flycatcher (an identifiable empid!) and the Cinnamon Flower-piecer. Along with the recently split Black-backed Oriole (seen at the motel while waiting for the battery charge), this makes three life birds for this abbreviated morning.
We are quite ready to push on up the hill for more birding but, alas, the battery is again dead and Pete (who has had the foresight to park facing downhill) has to roll down to the nearest town to get another jump start. At this point, early as it is, we have no real choice but to end our birding and head back to the airport. Our departure is at 6:40 in the evening with arrival at Newark at midnight.
The totals for the trip were high: we drove c. 3000 miles with a total group birdlist of 400+.
NOTE 1: Our experience with National Car Rental out of Mexico City was extremely bad. We were repeatedly told that their rental office was open 24 hours but, on our arrival, it was completely closed with a sign saying it would reopen at 7 am. We thus had to take a taxi to a hotel in the vicinity and return the following morning at 7 am. By 7:45 am, with the airport office still shut tight, we took a shuttle bus to the National lot where we were told that no cars were available of the type and in price range of our reservation. We were then offered something completely inadequate (no trunk, not big enough for four people and luggage).
Finally, in a classic bait and switch manoeuvre, we were offered a four-door with a trunk at a higher price level. After rejecting one with bald tires, we took a second one with slightly better tires. The car had only a quarter tank of gas and had many dents and scratches. What we didn't know was that it also had cooling system and battery problems that would turn up later. Our protests to National in the USA did, however, result in a partial reimbursement.
NOTE 2: Popo, which was already smoking during
our visit, is now predicted to have a major eruption some time in the near
future.

Strong-billed Woodcreeper (Xiphocolaptes promeropirhynchus).
Cerro S Fillipe 4/7/96. A very controversial
bird. Seen from the driver's seat on an adjacent tree trunk, then flying,
landing and perched in two other places with the following traits, all well
observed: large size, rather large and notably decurved bill; strikingly contrasted
and unmarked white throat; head streaks virtually restricted to head itself
and coming down no further than neck; back, wings and tail of a uniform ruddy
coloration.
Size of bird (flicker size) and curvature
of bill rules out rather smallish Spot- crowned; Black-banded and Barred are
well out of range and habitat and, in any case, have dark straightish bills;
Spotted is smaller, heavily spotted on the back and does not have a white
throat. The bill did not look as massive as it does in most depictions of
this species but, as I (ES) recall my one previous experience with this species,
in northeastern Venezuela, the bill also seemed less huge than expected from
the field guide depiction; however see Guy Tudor's version. This is known
to be a highly variable species with, in S.A. at least, the highland forms
described as smaller and smaller-billed with a uniform rufous-chestnut rump,
wings and tail (an outstanding feature of the bird in question).
One diagnostic feature, a black malar stripe
was not directly noted; however the striking effect of the white throat appeared
to be well set off, an effect that can be attributed to something like a
malar stripe. Note that two of the four observers disagree with this call
believing that the size of the bird and the shape of its bill were not "so
markedly different from other woodcreeper spp seen on this trip". On any
birding trip with 400+ spp there has to be at least one such controversy!
Paltry Tyrannulet (Zimmerius [Tyranniscus] vilissimus).
Yellowish bird with white eye stripe, originally
miscalled as Yellow-bellied Tyrannulet; in roadside foliage on road up to
ruins at Palenque in the early morning of 4/5. This species is not exclusively
a forest or canopy bird like the other Tyrannulet; Howell says "no other species
in region similar"
Greenish Elaenia (Myiopagis viridicata).
La Soledad 3/26/96. Flycatcher with a rounded
head sitting quietly high on a dead stub was almost certainly this species.
Least Flycatcher (Empidonax minimus).
From a large and often hopeless collection
of empids, this and the following 3 IDs are the most likely to be correct.
This quite gray bird at Puerto Angel had a Least-like chip, horizontal posture
as well as wing/tail flick; quite common in thorn forest at Puerto Angel

Botteri's Sparrow (Aimophila botterii).
Sparrows in roadway at Popo were well seen
in comparison with the Chipping Sparrows, adult and juvenile, also feeding
in the roadway: similar in size (perhaps a hair larger), longish tail but
rounded not notched, plain-breasted like the Chipping, large bill, flatheaded
look, brownish stripe behind the eye, back streaking seemingly cross-hatched
rather than length-wise as on the Chipping (and most sparrows). Hard to prove
the case but most likely this species which is widespread in Mexico; the

is that the species is generally described as very shy and secretive and
these birds were feeding out on the open roadway.
