Heard it again but had an obstructed view atm, then heard again in the late afternoon from indoors. Missed again. Otoh...I randomly saw a pair of hawks mating in a tree! Heard a ruckus, looked up, flipped out. Red-shouldered? It was quick. Also saw a cormorant later.
Since Ive been grumpy-posting about March and winter's end, I will say today was a nice example for a good March day, barely cracked 50 (high 52), sunny, light winds, very refreshing! I was surprised how much snow was hanging on in certain shaded stretches in the neighborhood.
