Physics in a feather.

At first glance, the throat of this Black-tailed Trainbearer (Lesbia victoriae) looks almost black.
Then, with a tiny change in position, it flashes brilliant green.
So, what happened?
The pigment didn’t suddenly change. The angle of the light did.
Iridescent hummingbird feathers contain highly organized, melanin-rich microscopic structures that interact with light. As the angle between the feather, the light and the observer changes, different wavelengths are reflected toward our eyes — revealing that spectacular metallic green.
A few degrees of movement can turn black into brilliance.
This is structural color in action — and one of the many reasons hummingbirds are such extraordinary subjects for observation.
Have you ever caught an iridescent hummingbird changing color right in front of you?

An Andean Gull (Chroicocephalus serranus) preying on an Slate-colored Coot chick (Fulica ardesiaca) — a striking and rarely witnessed interaction between two iconic Andean waterbirds.

Predation is often difficult to observe in the wild, and encounters like this offer a glimpse into the complex trophic interactions shaping high-elevation wetland ecosystems.

A remarkable field observation from the Andes, documenting the opportunistic predatory behavior of the Andean Gull.

Have you ever witnessed an Andean Gull hunting another bird?

🐦 50 bird species in one day… just outside Cusco?

The Andes around Cusco offer an extraordinary mosaic of high-elevation habitats where hummingbirds, tanagers, flycatchers, waterbirds and specialized Andean species can be found.

On our Cusco Day Birding Tour, we explore different habitats along the altitudinal gradient searching for species such as the Bearded Mountaineer, White-tufted Sunbeam, Rusty-fronted Canastero, Andean Parakeet and many more.

🌄 One day. Different habitats. Dozens of species.
