March 24. Arrived at 515 by met on No 4. - both birds even seen and heard along the SE powd line on the hill where they were surprising a red-tayt hawk, perched on the pole - the nots were thick and shields of single spiquity - worrying shribps. The came within about 15 ft of hawk but no close as far as I could see. The noths was frequent and given by both birds. I inspected the met - with chance except that a piece of soft willow while was run for the bottom of the nest. Gwent one overall shribus and hawk - the luths living at 75 yds - the shribu /moved along the wire as I came Close.
