Birding in Mexico: Bosques de Monterreal

A Blue-throated Mountain Gem feeding on flowers in the mountains

Our next stop was Bosques de Monterreal. On the way, we stopped for lunch at a favorite spot of Rene's. It was, by now, quite late, so there were only about three options on the menu: a thin broth with a hunk of meat and small scattering of vegetables (this part of Mexico is not big on the veggies) or some stews with beans and rice. I choose the latter with beef and was not impressed. I'm not a big meat person and don't care for heavy meals mid-day, so that was part of it. But, the meat was a bit fatty and tough and, well, it just wasn't my thing. 

Cute place, but ...

Then, we drove up the mountains into the cool green, passing numerous bear warning signs. We were headed into an are known for growing apples and having lots of Black Bears.

Some of the local crop

As we reached our first spot to bird, what did we see???? Two Black Bears – a mama and cub – running down the hill and beside the road behind a fence. We hadn't even pulled the car over and, by the time I jumped out with my camera, all I could see was two Bear butts behind the bushes. 

Still, what a treat!

Monterreal is a small ski resort situated in the municipality of Arteaga, in the southeast of the Mexican state of Coahuila, about 40 minutes from Saltillo and 90 minutes from Monterrey. 

Lots of mountains

It is the only commercial ski area in Mexico, with skiing on natural snow generally possible between December and February. Because of its elevation (ranging from 9,000 to 11,302 feet), it is cool, green and moist – a big departure from the Chihuahuan Desert. And, like any ski resort, it is filled with vacation homes, condos and housing developments.

We stopped outside the Bosques de Monterreal gated community to look for Susan's target: the Colima Warbler. 

A bosque is a forest habitat found along the riparian flood plains of streams, riverbanks and lakes. It derives its name from the Spanish word for forest. Bosques are found in Mexico and in the Southwestern United States (I have blogged about Bosque del Apache in New Mexico).

So, back to this magical Warbler: the Colima Warbler is cute, but certainly not spectacular. 

Kind of drab

Its allure lies in the difficulty of finding one. Found in the highlands of Mexico, it sometimes sings from atop bushes and small trees, but is otherwise generally stays low and well-hidden.

Making an appearance

It does not join mixed-species flocks, making it hard to find. The Colima Warbler breeds in oak scrub and thickets within mountainous pine-oak forests and winters in brushy flower banks and tangles. Most are found in Mexico, with a very small number breeding in the Big Bend region of Texas. To see one there, you need to hike up an arduous trail – often in high heat.

This one didn't take much effort (except a plane ride, guide and drive)

Susan had decided that that hike was too much for her, so Mexico was a good bet. And, it turned out to be. We saw a couple. Most were super hard to photograph ("low and well-hidden"), but I did capture one ...

The yellow is pretty

Susan was ecstatic. Rene said that Golden-cheeked Warblers (one of my nemesis birds) also frequented the area, but, alas, none were to be found.

We did see some familiar birds that I didn't photograph (a Band-tailed Pigeon, some Turkey Vultures, Acorn Woodpeckers, Mexican Jays, a Common Raven, a Clay-colored Thrush, a Yellow-eyed Junco, some Spotted Towhees and a Black-headed Grosbeak) and a couple of lifers for me.

I already talked about the Colima Warbler.

There were also two Gray Silky-flycatchers high up in a tree in very bad light ... 

I wish he had come closer

... and a skulking Brown-backed Solitaire that stayed deep in the thicket ...

Intent on hiding

We saw a gorgeous Rufous-capped Brushfinch that stayed in the bushes most of the time ...

One of my favorite lifers from this trip

... but did come out in the open for some glamor shots ...

Showing off

A slightly less beautiful relative also made an appearance.

Possibly a juvenile or molting adult

I also spent a lot of time trying to shoot a Blue-throated Mountain-gem Hummingbird as it flitted and landed deep in the trees ...

A new Hummingbird for me

... and then among some beautiful (but deeply shaded) flowers.

A pretty sight

I asked Rene if we were going to be able to get better Hummingbird views at any feeders and he said that no one has bird feeders for viewing in Mexico. As a result, almost all the Hummingbirds we saw were quickly flying by or in deep shade. 

The feeders at my house in Colorado facilitate photos

We never got any good views of their brilliant colors except that very distant Ruby-throated we saw in Valle de Soledad.

I am sure we would have had better results had we not gotten stuck in that traffic jam and had had more time, but we did OK.

Then, we drove back to Monterrey (in more traffic) to meet up with Heather at our hotel (our delay prevented us from picking her up). 

We had had a long day, so we decided to eat there. Not a great call. 

They did have the tortilla soup we had tried to get the night before, but it was an oddly sweet thick tomato-type soup, not the chicken-broth-based recipe I am familiar with. And, they still didn't have flan. Oh, well. We went to bird not to eat.

Birding in Mexico: Overview and Valle de Soledad

A trip built mainly on finding one small bird

Earlier this year, my friend Susan asked me if I wanted to join her and her friend Heather on a birding trip to Monterrey, Mexico, specifically to find one of Susan's nemesis birds, the Colima Warbler, and, generally, to bird this area. 

Rene, me, Susan and Heather

I didn't have any birding trips planned, so I said yes.

Susan had planned to take this trip a few years ago with friends Michele and Kathy (whom I birded with in 2019), but she broke her leg and couldn't go. 

So, this trip was with the same guide, Rene Valdes (RV Birding Tours), just different companions. 

The plan

The agenda looked like this:

Depart July 5 and fly (via DFW) to Monterrey and spend the night there.

Desert and mountains

Spend July 6 birding the Chihuahuan desert to look for Worthen's Sparrow and other desert specialties. 

Move on to the montane forest of the Sierra Madre Oriental to look for pine forest target species including Hooded Yellowthroat, Colima Warbler, Pine Flycatcher, Russet Nightingale-Thrush and others. 

Then, drive on to Cumbres de Monterrey National Park. We would spend the night in cabins at Mesa del Oso at 8,000 feet with possibilities for night birding for Owls and Nightjars. 

Spend July 7 birding Cumbres de Monterrey, including a nesting cliff for Maroon-fronted Parrots. Then, head back to Monterrey, stopping at La Estanzuela Natural Park.

Variety

On July 8, head to the mountains overlooking Monterrey and bird the Parque Ecologico Chipinque for a few specialties and then drive about 250 miles to Gómez Farías town at the base of the cloud forest El Cielo Biosphere Reserve. In the evening, we would bird the lowlands including a boat trip along a river looking for Sungrebes and Amazon Kingfishers. We would also visit agricultural areas to look for Aplomado Falcons, Tamaulipas Crows, Double-striped Thick-Knees and Altamira Yellowthroats. We would sleep at Casa de Piedra in Gómez Farías and do some night birding, looking for Tawny-collared Nightjars, Northern Potoos and Mottled Owls. The next day would bring more birding in El Cielo, driving up the mountain in a 4x4 truck to the village of Alta Cima and then back down for a second night in Gómez Farías town.

On July 10, we would bird the Gómez Farías-El Azteca road in the morning, looking for Thicket Tinamous, Great Curassows and the endemic Altamira Yellowthroat.  

Mountains and fields

Then, back to Monterrey before leaving for home on July 11.

I realized after I agreed to the trip that we may be seeing a lot of the same birds we saw in Costa Rica in 2022, but there were still about 100 new possibilities (and maybe better photos of some of the repeat birds).

Roadside Hawks in Mexico and Costa Rica

I went to England and Wales with Caty June 6-20 and to a music festival with Scott June 28-30, so I didn't have a lot of time to get ready. As I was thick in the midst of packing, including spraying my clothes with permethrin insect repellent, Rene sent us a note asking if we would mind changing the trip around in anticipation of Hurricane Beryl.

What???

I knew that Hurricane Beryl was the earliest Category 5 storm on record and I vaguely knew it was heading across the Caribbean. 

But, yikes, it was plowing directly towards where we were going

After discussions with Susan and (through her) Heather, we asked if we could postpone. Our thinking was that, even if the storm mellowed, as it was expected to do after slamming into Cancun, we would probably have rain and generally miserable weather. Plus, if it did re-intensify, we would be in Mexico in the middle of a disaster.

Rene was amenable and, so, we changed to August 12-18.

I rebooked my airline ticket (even got a refund credit because the new flight was cheaper) and watched as that damn storm took a big turn and completely missed Mexico's mainland!!! Oh, well!

Where it went

So, we went in August. It was a good trip. I saw 140 species, of which 34 were lifers. We didn't see many of the target birds, but we did see the Colima Warbler. So, Susan was happy.

And, even though Beryl didn't hit, some of the areas we went had been severely hit by Alberto in June, causing massive floods and washing out lots of roads, including the roads to the Maroon-fronted Parrot nest site and to our cabins in the mountains.

Rene regrouped a bit and I'll go through the agenda throughout the blog.

Heather front and center

Heather had just returned from a lengthy trip to Madagascar and contracted a stomach bug (as often happens with this type of travel). She almost canceled, opting instead to arrive a day late. 

Fortunately, she recovered somewhat and seemed fine during the trip. I am glad she made it, even though she missed Day 1. She is one of the best bird-spotters I have ever met.

About Monterrey

We hardly spent any time in Monterrey, but here's some basic information.

The capital and largest city of the northeastern state of Nuevo León, Mexico, Monterrey is the ninth largest city and second largest metro area in Mexico behind Greater Mexico City. It has more than 5 million residents and has been rated as the city with the best quality of life in Mexico. 

Flying into Monterrey

It sprawls across a valley surrounded by magnificent incredibly steep mountains. It seems clean and modern. The most we saw of it was our hour-long drive from the airport to our hotel for the first two nights, the Antares in the neighboring (and upscale) town of San Pedro.

A modern city

Located at the foothills of the Sierra Madre Oriental, Monterrey sits at 1,770 feet above sea level. The Santa Catarina River, which is dry most of the year on the surface but has flowing underground water, bisects the city into northern and southern halves. The river was dry when we passed it, but there was still some evidence of the June storm that flooded it.

Monterrey is one of the warmest major cities in Mexico. The average in August is 75°F- 97°F. And, it was cool compared to our more southerly adventures later on. Tell me again why we didn't go in January?

The green mountains and clouds fool you unto thinking it is cool

The night Susan and I arrived, Rene picked us up and it took over an hour to reach the hotel. Because it was fairly late, we ate in the restaurant there (snacked actually because they were out of everything we wanted), slept and left early the next morning to start looking for birds.

About Rene

Our birding guide, Rene Valdes, was delightful. 

Rene Valdes; Photo: BirdsEye

A wildlife biologist, his main vocation is working as an environmental consultant for wind farms across Mexico. He grew up in Mazatlán on Mexico's Pacific coast, but attended college in Monterrey and worked there for years before returning to Mazatlán. He has two daughters in Monterrey, so visits (and birds there) often. His master's thesis was on the rare endemic Maroon-fronted Parrot, so he is an expert.

Since it was so hot, he planned a trip that was exclusively birding by car. That was great because Susan has some significant mobility issues and hiking would not be an option.

You can see a lot from the road

So, let's go to Mexico! 

Warning: this was a birding trip, not a tour. So, most of what I talk about is birds.

Valle de Soledad

Our first morning of birding was along Camino a La Hediondilla in Valle de Soledad in the Chihuahuan Desert, southwest of Monterrey.

Our first birding stop

It took us two hours or so to drive to the desert. This is where we actually saw what Monterrey is. Lots of manufacturing plants and more trucks than you can imagine. The major trucking route from Mexico City to Laredo, Texas, passes through. 

From what I could see, commerce is good

We stopped for breakfast at a roadside restaurant that seemed to offer only exclusively egg dishes. I hate eggs, so I had a quesadilla. 

Simple

Unlike American quesadillas, this was just two small corn tortillas folded around a clump of slightly warm white cheese. I had some avocado on the side and liberally doused the thing with salsa. I was trying to follow the recommendation to not drink the water or eat raw vegetables except those with skins. That meant lots of avocados, no tomatoes and bottled water and diet cokes. I ate salsa and am still unsure as to whether that was a good idea. Although convenience stores carried bottled iced tea, it was all sweetened. So, my options were limited. As we started out, I had no idea that restaurants all serve pretty much the same thing anyway.

Valle de Soledad, a wide expanse of sparsely populated land (hence the name, which means "Valley of Solitude"), is in the Chihuahuan Desert.

Valle de Soledad

The largest hot desert in North America, the Chihuahuan Desert covers part of northern Mexico and the southwestern United States, occupying much of far West Texas, the middle to lower Rio Grande Valley and the lower Pecos Valley in New Mexico and a portion of southeastern Arizona, as well as the central and northern portions of the Mexican Plateau. 

Map: National Park Service

It is bordered on the west by the Sonoran Desert, the Colorado Plateau and the Sierra Madre Occidental range, along with northwestern lowlands of the Sierra Madre Oriental range. Its largest continual expanse is in Mexico, covering much of the state of Chihuahua, along with portions of Coahuila, northeastern Durango, the extreme northern part of Zacatecas and small western portions of Nuevo León. 

We were in the Nuevo León section

The Chihuahuan Desert covers an area of about 193,783 square miles (bigger than California).

The terrain mainly consists of typical scrubby desert basins broken by small mountain ranges that create "sky islands" of cooler, wetter, climates. It is biologically diverse with many endemic species. 

Grazing and agriculture have badly degraded many areas, killing off native grasses and replacing them with creosote and mesquite. The Mexican wolf, once abundant, was nearly extinct and remains on the endangered species list.

The livelihood is part of the problem

It is mainly a "rain shadow" desert created by mountain ranges that block moisture from the Pacific Ocean and the Gulf of Mexico. It mostly has an arid climate with one rainy season in the late summer and smaller amounts of precipitation in early winter.

A rare body of water

Because of its inland position and elevation (1,575 to 5,906 feet), the Chihuahuan Desert has a slightly milder climate in the summer than other North American deserts (daytime June temperatures are in the range of 90°F to 104°F), with mild to cool winters and occasional to frequent freezes.

Valle de Soledad has lots of yucca, Mexican fire-barrel cactus, cholla and grasses. Recent rains had also created a somewhat rare carpet of yellow flowers. 

Beautiful!

Mexico, including the desert, certainly delivers on butterflies. There were thousands, primarily Checkered Whites, in Valle de Soledad.

The United Nations reported in 2006 that nearly half of the bird, mammal and butterfly species in the Chihuahuan Desert are expected to be replaced by other species by 2055 due to climate change.

Most of the birds we saw are birds I have seen in the deserts of Colorado, New Mexico, Arizona and Texas, including these that I didn't photograph: Eurasian Collared-Doves, Rock Pigeons, White-tipped Doves, a Swainson's Hawk, a Say's Phoebe, Common Ravens, Horned Larks, Barn Swallows, House Sparrows, a Red-shafted Northern Flicker, Cassin's Sparrows and Lark Sparrows.

I did get pictures of lots of birds; here are some ... 

Female Golden-fronted Woodpecker

Canyon Towhee

Curve-billed Thrasher with its face stained by cactus fruit

Cassin's Kingbird

Loggerhead Shrike

Greater Roadrunner

We saw about 50 Long-billed Curlews

Three Crested Caracaras in a distant tree 

Bewick's Wren building a nest

Female and male House Finches

Male Lesser Goldfinch

 Doves: White-winged and Mourning

Northern Mockingbird

One of several Ruby-throated Hummingbirds (so hard to see as they flitted about)

Scaled Quail

Turkey Vulture

Western Meadowlark (there were so many!)

We saw about a dozen Burrowing Owls living among a new animal for me, the Mexican Prairie Dog. 

Mexican Prairie Dog

Although I have seen many, many Burrowing Owls in my life, I had struggled to find many during the summer of 2024. So, it was nice to get some up-close shots.

Not new by a longshot, but fun

We never found a Worthen's Sparrow, but I did get one lifer, a Botteri's Sparrow. 

Botteri's: We saw it only briefly and my photo is awful

It was a fun morning of birding but not terribly productive in terms of lifers.

This one had a clown-like face

We also saw two Rio Grande Coyotes, hidding behind some low bushes (maybe creosote).

This is the same species I had seen in South Texas in April. They were hunting (and catching) a rabbit. 

After about three hours of birding, we headed off for lunch and birding in the cooler mountains. Although we eventually got there, we had to endure about three hours stuck in a massive traffic jam caused by a perfect storm of high truck traffic, construction and two bad truck accidents.

We were afraid we would also have a perfect storm of rain as we watched typical afternoon clouds build and rain and lighting over the mountains we were heading to. 

Looking threatening

But, the traffic jam may have saved us there, because the rain was gone by the time we finally got where we were going.
