Thank you all for your advice, for the moment I put most of the flowering plants for the house, I covered others with a thin cloth, and even so the birds bit some flowers, I could see that these birds did not eat the flower, they only destroyed it with pecks. These days I have seen very few, as the weather is hot they may be returning to their place of origin. I also daydream about becoming a hawk, I would end up with squirrels and birds at the same time.
