Although around there and here patches of snow and in nights is below 0 but signs of springs are in the open air. After hard frost in February till -28C the ground is frozen enough deep. Yesterday as usual I was on walk. This day was cold enough and raining from time to time. After 20 min. my walk I heard a songs of lark high in the sky then saw the flying bird. It’s next prodromal of spring after starlings.
