Cooperation Beats Selfishness

Next to humans, leaf cutter ants form some of the largest and most complex animal societies on Earth. — Wikipedia

Last week on the WINGS birding tour in Veracruz, Mexico we encountered a long line leaf cutter ants carrying leaves to their nest. It is always fascinating to see how they cooperate.

Rather than eat the leaves, leaf cutter ants use them to grow their own food — a fungus — inside their underground nests. They work cooperatively to tend the fungus by feeding it freshly cut leaves, flowers or grasses, and removing mold and pests that threaten it.

This level of cooperation has made their species very successful. Why do they cooperate?

To answer this I’ll paraphrase my blog post of 8 March 2012.

While studying ant behavior, E. O. Wilson found that cooperation within a species doesn’t spring up easily but when it happens to start within a group, it makes the group survive so well that they dominate other groups. 

Selfishness beats altruism within groups.  Altruistic groups beat selfish groups.

— Rethinking the Theoretical Foundation of Sociobiology, David Sloan Wilson and E.O. Wilson, 2007

We humans see selfishness push everyone around and dominate the group. Unfortunately we’re encouraged to be selfish with slogans like “Be a winner” and “It’s all about you.”

But wait.  The second principle is true too.  Selfish groups lose out to altruistic groups.  Cooperation makes groups successful over others who are fighting among themselves or fearful of selfish individuals.

It’s important not to lose sight of this.  Humans have been successful as a species because we help each other.  Selfishness is a disadvantage to society.  Rugged individuals fail in the face of disasters; they ask for help.  We can’t do everything alone, and we cannot expect society to thrive if we insist that everyone pull himself up by his own bootstraps.

I am happy to know that ants showed the way on this.

In my view cooperation beats selfishness any day of the week!

A Few Flowers From Veracruz

Morning glory or perhaps sweet potato in the Veracruz lowlands, 30 Sep 2026 (photo by Kate St. John)

11 October 2026

Though birds were our focus on the WINGS birding tour in Veracruz, Mexico I found some flowers to catch my interest. I can only vaguely identify most of them, so if you have a more accurate identification please leave a comment to let me know.

At top, Google Lens says this pretty flower is a water morning glory (Ipomoea acquatica) but it was not growing in water in the Veracruz lowlands. Maybe it’s a sweet potato? Was it in a kitchen garden? I don’t remember.

Below, this sure looks like pearly everlasting (Anaphalis sp).

Google Lens says this is tornleaf goldeneye (Bahiopsis laciniata) in San Diego County, California. But the photo was taken in Veracruz Mexico highlands. Perhaps something very like what Google Lens thinks it is.

Tornleaf goldeneye — or something very like it — in the Veracruz highlands, 3 Oct 2026 (photo by Kate St. John)

This one came up as white prickly poppy (Argemone albiflora). I found it in a desert part of the Veracruz highlands near Xalapa.

“Purple nightshade” is a good description of this flower found in the Veracruz highlands. Google Lens suggests “giant potato tree” but this was not giant, so maybe it was just a potato.

This flower is incidental background to a photo of a shiny true bug on the lower petal.

Let me know the true identity of these flowers and I will correct the blog. Thanks in advance.

Not Olive and Not a Warbler

10 October 2026

On the WINGS birding trip to Veracruz, Mexico I was happy to see this colorful Life Bird, the olive warbler (Peucedramus taeniatus). I had missed seeing him while birding in southeastern Arizona, so I studied his description and habitat preferences before leaving for Mexico. I learned that his common English name is totally misleading. He’s not olive and he’s not a warbler.

Not Olive

Neither male nor female is olive colored.

The word “olive” is never used to describe the male at Birds of the World (punctuation edited): “Adult male distinctive in appearance, primarily gray. Head, neck, and breast orange tawny. Lores and auriculars black, forming prominent mask. Flight-feathers black, with prominent white wing-bars, tail spots, and white patch at base of primaries. Tail prominently notched. Southern populations smaller and brighter in color.”

“Olive” is never used for the female either. Birds of the World: “Adult female similar to male, but has yellowish head, neck, and breast, and grayish facial mask.”

Female olive warbler in Arizona (photo from Wikimedia)

But olive warbler is the name we have so …

The olive warbler prefers high elevation and “uses pines almost exclusively for foraging and nesting” from southeastern Arizona (rarely New Mexico) to northern Nicaragua.

Range of olive warbler (Peucedramus taeniatus)

His Spanish common name is better: Ocotero enmascarado = Pine-dweller in a mask(*). In Mexico he is also called Chipe ocotero = warbler pine-dweller(**).

Not a Warbler

Though this species resembles warblers it is not related to them at all. The olive warbler is the only species in his family, Peucedramidae, and his family is the only bird family endemic to North America (including Central America). In fact his nearest relatives are a family of sparrow-like high altitude birds in Eurasia, the accentors (Prunellidae).

Here are two of his distant nearest relatives, the dunnock and the alpine accentor.

Compared to the misnamed olive warbler these birds are drab.


More on naming:
(*) Ocotero is from the Nahuatl (indigenous) word ocotl which means “pine tree.”
(**) Chipe means “warbler” but the word also mimics the bird’s sound.

Hummingbirds Pause for a Sip While Migrating Across the Gulf

9 October 2026

One of the easiest hummingbirds to see on last week’s birding tour in Mexico were migrating ruby-throated hummingbirds. Right now they are still moving south but in only five months they’ll be on their way north again. Here’s where they are this week (4 Oct) on the eBird abundance map.

Weekly abundance of ruby-throated hummingbirds, week of 4 October (map from eBird Status and Trends)

Over the winter most ruby-throats stay in Mexico while others continue as far south as Costa Rica. By early February they are restless. Some of them mass at the Yucatan north coast, preparing to take the shortest route over the Gulf in a non-stop flight that takes 18 to 24 hours.

As hummingbirds approach the U.S. coast they encounter many oil and gas rigs, the green dots on this map by NOAA NCEI.

Map of oil and gas rigs and pipelines from NOAA NCEI. map pulled 20261009

Sometimes they are attracted to red colors on the rigs, as seen in the video below:

On 21 February 2018, Chuck, working on a drilling rig in the Gulf of Mexico, noticed humming birds hitting him on his red bandana and red coveralls. He saw another group hitting a fire extinguisher. He decided to get a cup of sugar water and watch what happened next.

Scenic Mountains, Flash Floods and Rivers of Raptors

8 October 2026

The mountains in Veracruz are very beautiful. On the morning of 4 October, fog shrouded the valley so that Malinche(*) was literally a sky island. (* I am not sure I’ve correctly identified this peak.)

Also from our elevated vantage point, we saw snow-covered Pico de Orizaba above the crest of the intervening hill. Click here for a marked-up photo indicating where to look.

In our travels we often saw Cofre de Perote in the distance.

Cofre de Perote, 3 October 2026 (photo by Kate St. John)

On sunny days the air heated quickly, rose from the valleys, and flowed over the mountains to generate afternoon thunderstorms on the eastward side. Even if it didn’t rain in Xalapa loads of water came barrelling down the steep watersheds and flooded roads in and near Xalapa.

No one waited for the floods to end. They drove right through them.

Notice the substantial rocks being carried by this flood across the Puebla-Xalapa Road on 4 October.

On 6 October, our last full day on tour, we spent 2 hours at the Cardel Hawk Watch on the Hotel Bienvenido roof. Between noon and 2:00pm 53,715 broad-winged hawks kettled up and streamed out in a River of Raptors! What a thrill!

A few days earlier, on 1 October, Moe Bell filmed this video of a kettle when the birds were closer.

Today I leave Veracruz, Mexico to fly home to Pittsburgh. I came for the River of Raptors and found so much more.

I first became hooked on the River of Raptors when I saw this video (below) in 2013 but I did not act on it until this year. 100,000 raptors(!), tropical birds, and so much more!

From the Highlands to the Sea

6 October 2026, WINGS Veracruz: Migration is a Moving Experience: Day 7, traveling from Xalapa to Veracruz (city)

Today we travel from the highlands at Xalapa to sea level at Veracruz. We’ll make birding stops along the way and look in at the hawk watches to see who’s flying by.

Versatile about elevation

The birds we saw above 4,000 feet generally do not come down to the foothills but there are a couple of versatile species that we may see up top and possibly encounter at sea level.

The rufous-capped warbler (Basileuterus rufifrons), pictured at top, is flexible about elevation but picky about moisture and thickets. He inhabits dry scrub and semi-open habitats from sea level to 9,800 feet.

The brown-backed solitaire (Myadestes occidentalis) is closely related to Townsend’s solitaire, a western mountain bird that occasionally visits Pennsylvania. Brown-backed solitaires inhabit semi-arid or pine-oak forests from 2,000 to 11,500 feet in Mexico and Central America. They like to sing year-round from a hidden perch so chances are good that we will hear one but not see it.

Mountains and foothills

The white-winged tanager (Piranga leucoptera) looks like a scarlet tanager though slightly smaller with a black face and white wing bars. He likes pine-oak forests and shady coffee plantations in the mountains and foothills.

The fan-tailed warbler (Euthlypis lachrymosa) of Mexico and Central America is the only species in his genus. He shares his common name with the “fan-tailed warbler” of Eurasia and Africa whose alternative common name is unforgettable and matches his song zit zit zit zit zit zit: the zitting cisticola (Cisticola juncidis).

The fan-tailed warbler of Mexico lives in foothills and montane forests with undisturbed understory. He follows army ants, not to eat them but to catch the insects the army scares ahead of them. When upset, he fans his tail. Here he’s yelling at a ferruginous pygmy-owl at Xilitla,Mexico. Look at that tail!

The Mexican sheartail (Doricha eliza) hummingbird is endemic to the Yucatan’s north shore and has a small population near Xalapa and Veracruz. He’s not very picky about elevation as long as there’s thorn scrub available. If we haven’t seen him yet, he’s pretty reliable at Laguna Miradores at 2,800 feet.

At the Hawk Watch, the species mix has changed

We were in the highlands for only five days (4 nights) so I expected the the big push of broad-wings to have passed — but not yet. Meanwhile turkey vulture numbers are increasing and soon, after we’re gone, the Swainson’s hawk (Buteo swainsoni) numbers will build.

The Swainson’s hawk is almost never seen near Pittsburgh so its light and dark color morphs may be a challenge for me to pick out in the sky. However, their big difference is size (larger) a shape (wings are longer) compared to broad-wings.

Swainson’s hawk color morphs as seen in flight: light, intermediate, dark (photos from Wikimedia)

Though Swainson’s hawks eat rodents during the breeding season in North America they spend the winter at the pampas (grasslands) of Argentina where they eat almost exclusively insects, especially grasshoppers.

Range map of Swainson’s hawk (from Wikimedia)

In the 1990s pest control of grasshoppers in South America caused mass die-offs of Swainson’s hawks.

Acute toxicity from poisoning by organophosphate insecticides monocrotophos and dimethoate, used to control grasshopper outbreaks in alfalfa and sunflower fields, caused the death of nearly 6,000 Swainson’s Hawks in Argentina in 1995 and 1996. Overall, an estimated 20,000 were killed in Argentina by pesticide applications. Deaths resulted immediately after hawks were sprayed directly by pesticide applicators while they foraged in fields or within several days after they ate poisoned grasshoppers. Many hawks died within minutes of being sprayed, and their carcasses were found in adjacent fields (Woodbridge et al. 1995a, Goldstein et al. 1996 MJB).

— Birds of the World: Swainson’s hawk

Fortunately … !

After this incident, these pesticides were banned and an educational campaign began to bring awareness to the problem. These programs seem to have been successful.

— Buffalo Bill Center of the West: Introducing the Swainson’s hawk
At the Sea

After the hawk watch we’ll be back at our seaside hotel in Boca del Rio where we might see a yellow-winged tanager (Thraupis abbas) in the garden. This bird is so versatile about elevation that we saw him in the highlands at parks, gardens and forest edges.

Tonight we have our last dinner together. We leave for home tomorrow.

Birding Above 5,000 Feet

5 October 2026, WINGS Veracruz: Migration is a Moving Experience: Day 6, the highlands around Xalapa and Cofre de Perote

In the lowlands we saw many familiar northern-breeding birds within the migration corridor, but now we’re in montane pine-oak and fir forests at 4,000 to 11,500 feet (1200m to 3500m), both pictured below.

Fir forest at Cofre de Perote (photo from Wikimedia)

At this altitude many of the birds are new to me including the red warbler (Cardellina rubra) at top. Birds of the World describes him:

A standout in an already distinctive family, Red Warbler is easily identified by its strikingly red plumage and silver or dark gray auricular patch. Endemic to three disjunct mountain ranges in Mexico, this montane specialist inhabits the edges of pine-oak forests from 2900-3500 m (9,500-11,500 ft) during the breeding season, which stretches from February to August; however, it descends mountain slopes in the winter to around 1800 m (6,000 ft), where it often associates with mixed species flocks.

— Birds of the World: Red warbler

The red warbler probably descends the mountains at this time of year because it feeds on insects, including Neuroptera, which may not be as abundant in the mountains in winter. This Neuroptera, for example, occurs in Veracruz, Mexico: a green lacewing. The bird is beautiful and so is its food.

Here are ten more potential Life Birds above 5,000 feet. All of these are endemic to Mexico.

Birds in order of appearance with paraphrased information from Birds of the World:

  1. Bearded wood partridge (Dendrortyx barbatus): Listed as Vulnerable, this elusive bird forages in pairs or small groups and flies at the slightest sign of alarm. (How will our tour sneak up on it?)
  2. Strickland’s woodpecker (Leuconotopicus stricklandi): Strickland’s is brown and white instead of familiar black and white of the woodpeckers back home.
  3. Transvolcanic Jay (Aphelocoma ultramarina): This jay is a split from the Mexican jay that’s endemic to the trans-Mexican volcanic belt that spans Mexico’s “waistline.”
  4. Gray-barred wren (Campylorhynchus megalopterus): usually encountered in small bands of up to a dozen individuals which move through upper levels of vegetation.
  5. Ocellated thrasher (Toxostoma ocellatum): although it forages mainly on the ground, it is most usually found singing from an exposed perch. Very difficult to approach closely.
  6. Russet Nightingale-thrush (Catharus occidentalis): This species is not as difficult to observe as some Catharus thrushes. It forages on the ground and sometimes visits open areas, especially at dusk and dawn.
  7. Striped sparrow (Oriturus superciliosus): Forages in small groups, often with one or more individuals perched atop a small tree or bush acting as a sentinel while the rest of the flock forages among bunchgrasses. [I think it looks like a heavy-bodied chipping sparrow that has a black eye.]
  8. Collared towhee (Pipilo ocai): Amazingly there is not much information on this bird.
  9. Rufous-capped brushfinch (Atlapetes pileatus): Favors dense brushy areas and is often rather skulking, but also curious. Investigates scolding groups of other birds. Usually in pairs, sometimes in small groups, foraging in weedy vegetation. (This explains why photos are hard to find and very poor light.)
  10. Hooded yellowthroat (Geothlypis nelsoni): It resembles and behaves like a common yellowthroat except “unlike most yellowthroats, not found in marshes.” Can be difficult to distinguish from common yellowthroat. Uh oh.

I’m hoping to see the beautiful golden-browed warbler as well. It is nearly endemic.

The very attractively plumaged golden-browed warbler (Basileuterus belli) is almost endemic to western and southern Mexico, although its range reaches as far south as Honduras and El Salvador.

Fun Fact about the wedge-tailed sabrewing. 15th in the slideshow and pictured below.

Wedge-tailed sabrewing (photo from Wikimedia)

The Wedge-tailed Sabrewing is a hummingbird that not only hums, it sings. And sings. And sings even more. Its song is so complex as to make one wonder about the appellation “songbird” being limited to oscine passerines. … This prodigious serenading emanates from clusters of males known as leks, which form to attract females more effectively.

88 Butterflies

Anna’s 88 (Diaethria anna), ventral view (from Wikimedia)

3 October 2026, WINGS Veracruz: Migration is a Moving Experience: Day 5, the highlands near Xalapa

“88” is not the count of butterflies we’ve seen on our birding tour. It’s the common name of Diaethria sp. butterflies whose wings have an “88” or “89” pattern on them.

There are 12 species of Diaetheria butterflies, some of which are found in Veracruz including the Anna’s Eight-Eight (Diaethria anna). The adults feed on rotting fruit, tree sap, and dung, so don’t look for them at flowers.

Diaethria butterflies have completely different colors and patterns on their dorsal and ventral sides — so different that they don’t look like the same butterfly.

Widespread 88 butterfly (Diaethria cylmena) showing both sides of wings, Brazil (photo from Wikimedia)

The ventral side (wings held closed) has a white background with black lines that almost make concentric circles surrounding the numerals 88 or 89 in the center. The upper wing is red but mostly hidden by the other wing. This side of the butterfly is always black, white and red.

Widespread Eighty-eight butterfly, Diaethria clymena, ventral view (from Wikimedia)

The dorsal (upper) side is nothing like the “88” side. It is velvety-black with a slash of color on each wing in iridescent blue or green or yellow.

The “88”s on these butterflies develop in the same way that stripes and spots develop on zebras, tigers, leopards and giant pufferfish. They are called Turing patterns.

Turing patterns on zebra, tiger, leopard, pufferfish (composite from Wikimedia photos)

The numerical patterns visible on the wings of the “88 butterfly” [Diaethria sp.including] (Diaethria clymena) originate during embryonic development from morphogenetic mechanisms described by Alan Turing in 1952—known as Turing patterns.

And finally, we carry Turing patterns on our fingers. That’s what fingerprints are!
