Month-by-Month Istanbul Birding Guide

Month-by-Month Istanbul Birding Guide

Introduction

You know Istanbul for its majestic domes and bustling bazaars. But look up. Above this ancient crossroads, another epic migration has been flowing for millennia—a silent river of wings connecting continents. This spring, trade the well-trodden path for a hidden trail, and discover why Istanbul is whispered among global birders as one of the planet’s most astonishing urban wildlife spectacles.

This Isn’t Just Birdwatching. It’s Time Travel.

Imagine standing on a forested hill in Asia, with a view of Europe in the distance. In your binoculars, not ships, but a flock of Lesser Spotted Eagles—each with a seven-foot wingspan—soaring on thermals that have carried them from Africa. Minutes later, a kaleidoscopic swirl of European Bee-eaters, jewels against the blue, chatters past. This is the Bosphorus Flyway, and for a few magical weeks, Istanbul becomes the world’s greatest theater of migration.

Our exclusive “Istanbul Skyway” day tour is curated not just to show you birds, but to immerse you in this phenomenon. We are not just guides; we are your interpreters of this aerial odyssey.
