The first one arrived at 07:18.
Not visually. Audibly.
Three short, liquid notes somewhere above the riverbank, followed by silence. I stopped walking and looked up, but there was nothing there. Just a pale blue Madrid sky beginning to warm after a surprisingly cool night.
A few seconds later came the call again.
This time there were two birds.
Bee-eaters have one of those sounds that seems almost too tropical for Europe. If you hear it for the first time without knowing the species, your brain immediately starts searching for something exotic. A parrot escaped from captivity perhaps. Something from a nature documentary. Certainly not a bird that has travelled thousands of kilometres to spend the summer in central Spain.
Yet here they were.
I followed the sound towards a sandy bank along the Jarama where I had seen nesting activity in previous years. The colony itself was still quiet. A few swallows skimmed low over the water and a pair of magpies were conducting what appeared to be a serious disagreement in a nearby poplar.
Then a flash of colour crossed the river.
Even after many years of seeing bee-eaters, the colours still feel slightly improbable.
Chestnut, yellow, turquoise and green. Nature occasionally appears to lose interest in camouflage and simply experiments for a while.
The bird landed on a dead branch and immediately began scanning the air around it. Within seconds it launched forward, caught an insect, returned to the perch and repeated the process.
This is the rhythm of a bee-eater’s day.
Perch. Scan. Chase. Return.
The name suggests an obsession with bees, but their diet is considerably broader. Wasps, dragonflies, beetles and many other flying insects all appear on the menu. They are aerial hunters, built for precision and speed rather than endurance.
Watching them hunt is strangely relaxing. There is no obvious effort involved. No wasted movement. Just a series of small calculations carried out at high speed.
The birds that spend summer here have typically arrived from sub-Saharan Africa after crossing the Sahara Desert and the Mediterranean. It remains one of the more extraordinary migrations undertaken by a species that most visitors notice only briefly before reaching for a camera.
Migration often sounds neat when reduced to a map.
A line here. An arrow there.
The reality is thousands of decisions made by individual animals navigating weather systems, predators, habitat changes and simple bad luck.
Not every bird that leaves Africa reaches Spain.

A cyclist stopped beside me while I was watching the colony.
“Kingfishers?” he asked.
I pointed towards the branch where three bee-eaters were now sitting together.
He followed my finger, paused for a moment and smiled.
“I’ve lived here twenty years,” he said. “Never noticed those.”
That comment stayed with me long after he disappeared down the track.
One of the great pleasures of fieldwork is discovering something new. The other is realising how much is happening around us all the time without attracting attention.
Bee-eaters are not rare in many parts of Spain. They are not particularly secretive. They are brightly coloured, noisy and often highly visible.
Yet countless people drive, cycle and walk past them every summer without ever knowing they are there.
By mid-morning the colony had become considerably more active.
Birds crossed back and forth above the river carrying insects. Others disappeared into nesting tunnels excavated in the sandy bank. The calls that had seemed isolated earlier merged into a constant background conversation.
The colony felt alive in the fullest sense of the word. Not dramatic. Not urgent. Simply functioning exactly as it has for generations.
As the temperature climbed, I packed away my binoculars and started back towards the car.
Halfway along the path I heard the call again behind me.
Three short notes.
The same sound that had stopped me an hour earlier.
I turned instinctively, though I already knew what I would see.
A bee-eater passed overhead, caught the sunlight for a moment, then vanished beyond the trees bordering the river.
A few seconds later the sound disappeared too, leaving only the wind moving through the reeds.
