Readers’ wildlife photos

Today we have some travel and wildlife photos from reader Jan Malik.  Jan’s captions are indented, and you can enlarge the photos by clicking on them. (Don’t miss the Taiwan barbet!)

Here are a few pictures I took during my short stay in Taipei, Taiwan (Republic of China) in 2016. Business trips usually allow very little time for sightseeing — the familiar, morbid cycle of airport → hotel → conference room → hotel → airport — but on this occasion I had a few free hours in the afternoon. Naturally, I decided to explore the nearby Taipei Botanical Garden with a birding lens that mysteriously strayed into my suitcase:

On my way to the Botanical Garden, I visited the National Chiang Kai-shek Memorial Park and Hall, the latter built in the late 1970s after the President’s death. I include it here for documentary reasons — who knows how long it is going to survive, given the volatile political situation.

Inside stands a larger‑than‑life sculpture of the Generalissimo. Taiwan’s history is typical of right‑wing dictatorships which, like South Korea, Spain, or Portugal, began as oppressive authoritarian regimes and then evolved into genuine democracies. Conversely, left‑wing dictatorships typically resist fundamental change and persist until their eventual collapse:

Onward to wildlife. The entrance to the Mausoleum was guarded by a lion (Panthera leo var. lapideus):

Already in the Botanical Garden, I encountered a cat, doing what cats do best – contemplating:

In one of the alleys I came upon a sizable crowd — people were observing local celebrities, a pair of nesting Oriental magpie‑robins (Copsychus saularis). The birds seemed completely unfazed by the attention, the male singing and standing guard at the nest;

These birds are bold and well adapted to human habitats. The female does most of the feeding; here she brings an unidentified moth to her chicks in a rotted‑out branch stump:

At a nearby pond I spotted a duck. It was likely a domestic bird, possibly with a dash of wild Mallard  (Anas platyrhynchos) ancestry:

The pond was full of lotus plants, which provided excellent habitat for the Common moorhen (Gallinula chloropus). Like all rails, these birds have relatively small wings and strong feet, well suited to foraging on land as well as in water. They swim well despite lacking webbing between their toes. These traits help explain why, when rails successfully colonize remote predator‑free islands, they often evolve reduced flight or complete flightlessness;

Moving further along the park alleys, I spotted a Taiwan barbet (Psilopogon nuchalis) looking out of its nest cavity. As an endemic species, it was a special find for me. Barbets vary widely in sexual dimorphism — in the Taiwan barbet the sexes are practically indistinguishable, in others (like the Coppersmith barbet) the differences are subtle, and in still others (such as the Red‑and‑yellow barbet) they are striking. I wonder why, in this species, bright coloration in females is not maladaptive. Perhaps the fact that they are obligate cavity nesters shields incubating females from predators. The same logic applies to woodpeckers, whose sexes are also similar aside from modest red patches in males:

Shortly after the barbet, I hit another jackpot in my endemics count — the Taiwan blue magpie (Urocissa caerulea). Like other corvids, it is social and omnivorous, and like Taiwanese barbets, it is sexually monomorphic. Corvids also evolved cooperative breeding: fledglings often remain with their parents and help raise the next brood. This likely evolved through kin selection. Why does it work so well in corvids and not in most other birds? Perhaps in environments with limited resources, young birds have better reproductive success by helping relatives than by attempting to breed independently?:

Having spent some time observing the magpie, I moved on — my remaining time before the flight was getting short. Soon I saw another first for me, though a common sight in Southeast Asia: the light‑vented bulbul (Pycnonotus sinensis). An omnivorous bird, here it was about to snatch a ripe fig:

Moving on, I photographed a dragonfly, which I believe is a male Crimson Marsh Glider (Trithemis aurora). These insects are sexually dimorphic, with olive‑colored females. This male appears to be orienting its abdomen toward the sun to reduce the surface area exposed to solar radiation and prevent overheating — a behavior known as “obelisking”:

Near the Botanical Garden exit I saw the last animal in this series, the Eurasian tree sparrow (Passer montanus). They always bring a smile to my face. Unlike many other sparrows, the sexes are alike. In 1958 they were targeted during China’s “Four Pests” campaign, a fine example of how ideology can override basic biological understanding:

While driving toward the airport that evening, I saw a Buddhist temple by the roadside, adorned with a symbol that, in European cultural circles, evokes entirely non‑religious sentiments. It was adopted in the 1920s by the National‑Socialist German Workers’ Party, but in Asia it is an ancient religious emblem. It is not identical to the Hakenkreuz — it “rotates” counterclockwise — and its meaning here is entirely benign:
