Why do silver gulls behave like true kings of the urban streets? This lecture is an opportunity to look at familiar strangers in a new way. Together with biologist Alexander Kulev, participants will learn about the habits, ecology, and complex relationships of these birds with the city. Surprising facts are guaranteed! The silver gull is a bird we are used to seeing in the city as something ordinary. However, behind the familiar appearance lies an amazing and almost unexplored world. Why do they feel at home in St. Petersburg, even far from water? Why does their behavior often provoke debates and speculations? In the lecture "Familiar Strangers: Silver Gulls," you will not only hear the answers but also rethink your perception of these feathered neighbors. The speaker - Alexander Kulev, candidate of pedagogical sciences, biologist, educator with 40 years of experience, and author of popular science books - will help you look at gulls not from a mundane perspective, but from a scientific and even philosophical one. He will talk about how the lives of these birds are structured, what their habits are, where they nest, how they interact with the urban environment, and why their role in the ecosystem turns out to be much more significant than it seems. Systematics, migrations, behavior, nutrition, relationships with humans - all this will be discussed in an engaging and accessible form. Even if you have never been interested in ornithology, the lecture will captivate you: after all, it is not just about birds, but about living beings with whom we share the city every day. This event will be a true discovery for schoolchildren, students, nature lovers, and anyone who cares about urban mysteries. And the cozy atmosphere of the library on Stremyannaya will create the perfect space for a lively dialogue and a new perspective on the everyday.
