It is said that when swallows fly low, even if it is sunny, it rains in the afternoon. Something like this happened yesterday in Torelló, in Osona, when there was a large concentration of these birds before the storm arrived.
Dozens of these birds gathered perched on the balconies and wiring, as we see in La Vanguardia's Readers' Photos, before taking flight and disappearing with the first drops of rain.
It also seems as if the swallow did not want to emigrate this year. It is a bird that usually arrives between April and May, when temperatures begin to increase and it begins to flower, and the last specimens remain until the end of August. But, with climate change, everything seems disrupted.
The barn swallow is an open-country bird that typically uses human-built structures to reproduce.
It builds cup-shaped nests with clay balls in barns and similar buildings, and feeds on insects it catches in flight.
