As I live in Riga city center we have a lot of seagulls. There was a nest of them on our roof and the babies kept falling down - it was so annoying!!!

At the start of the seagull nesting season, birds look for a place to nest and will lay their eggs in March and early April. They may choose a sheltered position on the roof between chimney pots or against an air vent and often return in the following years.
