Chiapas Owls

Chiapas owls - Unspotted-Saw-whet-Owl

The Unspotted Saw-whet Owl is a highly sought after species that inhabits the cloud forest mostly above 8,000 feet in elevation. In this photo, light dew is visible on the owls head from the mist in the forest.

After 15 years, I finally got brave enough to go back in search of the Chiapas Owls. Chiapas is the southernmost state of Mexico that borders Guatemala. This was pretty much a mandatory destination to complete our sister website. There is no other state in Mexico with as many owl species as Chiapas. This area is also crucial to our current understanding of owl taxonomy. New divisions and more accurate classification of the owls are slowly becoming known and being clarified by science.

Chiapas is spectacular for wildlife and has an extraordinary history, but suffers from terrible pollution and horrific habitat destruction. While the natural wealth is immense, the population is poor, and traveling there can be dangerous. Having done this before, my plan was to mitigate risk, so I invited a friend and hired a guide. We documented nine species of owls in nine nights (video, recording, photograph, etc.) along with over a hundred eighty species of birds and mammals in the daytime. I will cover more of this in an upcoming article.

The Chiapas owls comprise 19 different species. Although none are specifically endemic to this state, some have very small ranges and are reliably only found here or Guatemala, which may be even more dangerous for travel. Below is a list of the Chiapas owls. This list reflects our most current knowledge. The owls are not well studied; most species are at some level of threat, and Central America has a poor record for wildlife conservation.

Having nine nights, we prioritized our search for the Chiapas owls for the species that are difficult to find in other places or those that are less well known to science. Our primary target for this trip was the Unspotted Saw-whet Owl. On previous trips searching for this species (in both Chiapas and Costa Rica) I had missed or never gotten close enough to photograph this species. In four nights of searching for this owl, we managed to document two individuals. Both were high in the cloud forests above 8,000 feet in elevation. The real delight was the one that landed on our guide’s head! I missed that photo I am sorry to say.

Unspotted Saw-Whet Owl

Chiapas owls - Unspotted-Saw-whet-Owl

Unspotted Saw-whet Owl in the cloud forests were sometimes very bold and sometimes very timid. Never a simple find, we spent 4 nights hearing them before we ever saw one.

Unspotted Saw-whet Owl is considered critically endangered in Mexico. There have been scattered sightings of this owl in Guatemala, Nicaragua, Costa Rica, and Western Panama. The threats of deforestation are of major concern for this cute little owl. Since they live in scattered and remote high-elevation cloud forests, there are no accurate population estimates for this species. The dangers of destroying nocturnal species like this one are great. This is particularly true of species in third world countries with high population growth and density, where the forests are being destroyed for fuel and agriculture. This is exactly the case in Chiapas where air pollution from the burning and stripping of the forests is widely prevalent. The balance of nature depends on the nocturnal predator base. So little is known about the owls and they are so seldom seen that they are all too easily destroyed.

Guatemalan Pygmy-Owl

Chiapas owls - Guatemalan-Pygmy-Owl

Guatemalan Pygmy-Owl has been split from Mountain Pygmy-Owl as science is clarifying both pygmy and screech-owls in Central America.

Next on our list was the newly-defined Guatemalan Pygmy-Owl. It has a very small range in Mexico and Guatemala and possibly also Nicaragua. This owl is also a high-elevation species found at over 8,000 feet. This is a small, sparrow-sized owl that is diurnal, and very difficult to find, observe, or photograph since it stays way up at the top of big trees in the dry forest canopy. Current research has proposed this division from the Mountain Pygmy-Owl based on geographic separation, DNA, and vocal differences. We agree and have followed this taxonomy on our website.

Bearded Screech-Owl

Chiapas owls - Red morph Bearded-Screech-Owl

Bearded Screech-Owl is found in both red and brown color forms. This species has a very small range.

Bearded Screech-Owl was also high on our list of Chiapas owls. Finding this cute little screech-owl was fairly simple compared to the other owls we sought. Although in previous trips into this region, I had found this species at lower elevations, it was also in the cloud forests where we were looking for the Unspotted Saw-whet Owl. In general, we sort of stumbled upon this owl while searching for the other Chiapas owls.

Bearded Screech-Owl occurs in both brown and red morphs which are about equally abundant. This owl has a very restricted range limited to Chiapas and Guatemala. It faces the same threats of deforestation and habitat loss as the Unspotted Saw-whet Owl does. The difference between the threats to these two owls is in range and density. The Unspotted Saw-whet Owl is solitary and has a territory which makes its population density very low. It has a larger range but a low density within that range. The Bearded Screech-Owl has a very small range but lives in a social collection or group. When you find these owls, there are several in an area.

Guatemalan Screech-Owl

Chiapas owls - Guatemalan-Screech-Owl

Guatemalan Screech-Owl is also called Middle American Screech-Owl.

Guatemalan Screech-Owl is a species with an extensive range from Sonora in northwest Mexico and Tamaulipas in northeast Mexico to Nicaragua. I have heard this owl many times and taken pictures of it in the past. Its call is extremely ventriloquial making it almost impossible to find. It is also very timid in my experience. Our guide claimed this was a simple owl to find in the Naha area so it was an important species for us. “Ha, ha, ha!” is what I must say to this. Yep, some people stumble upon this owl during the right time of year or place or moon phase or who the heck knows how, but reliably seeing this species is not easy. We went to and stayed in the Naha area twice before we finally got decent views and documentation.

Naha is near the Guatemalan border. We had gone there at the beginning of our trip, although being determined to get photos of Guatemalan Screech-Owl we decided to return at the ending of our journey. Although there were lots of them to be heard, seeing this owl is not easy. On our second trip to Naha we did finally get very good views, recordings, video, etc. of the species. The northern race of Guatemalan Screech-Owl is much less heavily marked than this southern race so it was very interesting. The owl in the photo shown here was very obliging, so we also had the opportunity to take video. We have posted it on our website on the video tab of the Guatemalan Screech-Owl page.

Pacific Screech-Owl

Chiapas owls - Pacific-Screech-Owl

Owls vary in both color and eye color. This particular individual had gorgeous yellow-orange colored eyes. This is the natural color of his eyes (not “photo-shopped”).

Having been to Oaxaca in recent times to see the newly-defined Oaxaca Screech-Owl, that we wrote about here on our blog, it was important to get clear documentation of the Pacific Screech-Owl in Chiapas. The Oaxaca Screech-Owl was formerly lumped with the Pacific Screech-Owl. These two species are extremely different. Owls are first defined by their vocalizations since this is how they find each other at night. This, in turn, drives speciation. I had been to the Puerto Arista area previously and knew that Pacific Screech-Owl was common. Having limited time, I was interested in some basic documentation of this owl from this area.

Chiapas owls - Pacific-Screech-Owl

This individual is much lighter in color than the owl in the previous photo. It also has much more yellow colored eyes.

Not to get too off track here, the Oaxaca Screech-Owl, which has a very limited range along the Oaxaca coastline, at some point becomes Pacific Screech-Owl. The two species can be distinguished both visually and vocally. Since I had been to Oaxaca in recent times it was important to see the Pacific Screech-Owl right at the Oaxaca / Chiapas border. In a future trip, I will look along the southern coastline of Oaxaca and see where these two species divide and what happens in the mix if such an area exists.

Coastline property is high value real estate and in high demand. The Pacific Screech-Owl has a very narrow range along the coast from Chiapas to Costa Rica. This owl is facing some of the highest and immediate pressures to its habitat. Coastal development in Central America is putting real pressure on the small remaining native habitat. The changes to this area from when I was last here 15 years ago were frightening. I had assumed this would be a simple owl to find, and it was, although mostly because their habitat was so limited that there were only a few places it could be. The increases in human population, and disappearance / destruction of the owls’ habitat was saddening. My hopes for nice, clean coastal air were sadly demolished.


Next on our Chiapas owls list were Crested Owl and Black-and-White Owl. Knowing we were going to need to be closer to the Caribbean side of Chiapas, we headed for the Palenque area where these species had been reported. To interject here, the ruins are spectacular. It is amazing that mankind could build such incredible structures here in the Americas so long ago (230BC – 790AD).

Ridgeway’s Pygmy-Owl

Chiapas owls - Ridgeway's Pygmy-Owl

Those feet are why this owl is so hated by all the other small birds! If he wore shoes they would be a size “14”. This owl is designed to catch and eat other small birds.

Back to the Chiapas owls, after our sightseeing in the ruins we needed to get a room before searching for the owls at night. Directly down the road, we found a room for the night. As we arrived, some of the other guests, spotting our cameras, asked us what we were doing. We explained that we were there to photograph the owls. Coincidentally, a Ridgeway’s Pygmy-Owl flew into the tree overhead. “Ah, listen” I said. The other guests were very surprised when we showed them the owl in the trees overhead. This was certainly fortuitous timing. Knowing the owl sounds and recognizing that there was one very close-by definitely made for an interesting lesson in observation.

You may be asking “What is a Ridgeway’s Pygmy-Owl?”. Ferruginous Pygmy-Owl has been split. What used to be a Ferruginous Pygmy-Owl in North and Central America is now a Ridgeway’s Pygmy-Owl. This division is new and will be more commonly used as this species name becomes standard in the field guides. The Ferruginous Pygmy-Owl is now a species found in South America. Again, this is an example of our growing knowledge of the owls and understanding of nature in general as research is done. This is also another example of the concerns about the disappearance of wildlife before we even know what is disappearing. The biodiversity of our planet is in sharp decline and the owls are extremely vulnerable.

Crested Owl

Chiapas owls - Crested-Owl

This owl has his wings partially open to make himself look larger. This is a common Crested Owl defensive posture, as he looks down at us from his perch.

So again, back to the Chiapas owls. After settling in our room, we decided to check the local area around Palenque. I had heard that Crested Owls were near the ruins but entry into the ruins at night is highly restricted. Since we did not get the required permits in advance, we were limited to checking the perimeter areas. This was just fine and we did find several Crested Owls.

Mostly people see Crested Owl when they run across them on daytime roosts. As I speak to the guides in Central America, they often claim that seeing this species takes lots of patience. My last experiences at night with these owls in Costa Rica were very frustrating. The owls in multiple locations were vocal but always stayed high in trees, mostly out of view. When we found them lower in the canopies they were extremely timid and would only be seen for brief moments flying between the trees. Although generally high in the canopy here, the Crested Owls several times came out into the open where we could clearly see them.

Black-and-White Owl

Chiapas owls - Black-and-White Owl

Black-and-White Owl is very visually distinctive in Central America. No other owl in Central America has the black and white colors. The Black-banded Owl of South America is the only similar species although it is smaller and has a different call.

While looking around the Palenque area we also found Black-and-White Owl. I expected this owl here having found them here before. This is generally a fairly bold species, in particular, early in the evening. It seems as the night progresses they become a little more cautious. Maybe they just become more alert and slightly more cautious of people. We found this species late at night and although visible, not like I have seen them in the past when I have had to back away to take a picture. This owl is unique in appearance. Both the Crested and Black-and-White Owls were a pleasure to see here.

Mexican Wood Owl

Chiapas owls - Mexican Wood Owl (Mottled Owl)

The southern race of Mexican Wood Owl has much darker markings than the northern race although this individual was very dark for even the southern race.

The last owl species of this trip was a Mexican Wood Owl. Again, if you are familiar with owls, you may be saying “What is a Mexican Wood Owl?”. This species has also been split from its similar South American cousin. Formerly named Mottled Owl, the nominate species in South America retains the common name and the Central American Mottled Owl is now named Mexican Wood Owl. As an analogy, both Volkswagen and Ferrari are cars with four wheels but they are very different. The owls can quickly be identified by their primary call. If the call is different, it is a different species. Science and the guide books may take a while to catch up, but those of us in the field know this.

North of Arriaga, we had gone into the El Ocote forests to see if we could find the endangered and endemic Nava’s Wren (which we did find and photograph but that’s for another article). As it became dark several Mexican Wood Owls were present. This is the darker southern race of Mexican Wood Owl. Those in the north of Mexico are much lighter in color and markings. This area is right where the dividing line between these two races of Mexican Wood Owl occurs. Interestingly, we have seen the northern race of this species in Oaxaca in areas that are actually further south than El Ocote. This is generally a fairly bold and aggressive owl. It is very diverse in diet and habitat. Mexican Wood Owl is a very interesting owl that is quite common in Mexico and Central America.


So, this is a bit about the owl species we found in our short visit to Chiapas. As more is known we may see more clarity in the taxonomy of the owls. Mankind is accountable for what we do to our planet. The owls can be destroyed without the eradication being seen. It is our hope that more of us will get interested in nature. It cannot be protected if we do not get interested and aware. I am sorry to say that so much of what we saw may disappear. Our oceans, land, and air cannot sustain nature at the rate we are blindly polluting and overpopulating. Get interested. We live in a magical amazingly biodiverse planet and there is as yet no real way for us to get anywhere else in the vast universe. Even if we could, it would be a travesty if we had destroyed what was here.
