观察细节
Including 1 *beyond property boundary*. At ca 1225, observed 6 CORA on the RR tracks ca SW of the rocky draw, then 4 took off and flew in a vocal group for several minutes. Was this 2 mated pairs?? At 1255, I saw 2 CORA fly over, loosely together, from the N to S, 1 making low "bronk bronk" calls. A few minutes later, I saw 2 flying closely together low over the field S of the creek, doing dives and turns. At ca 1320, I saw 6 ravens perched within ca 500 m, 4 in separate (momentary) pairs, in the vicinity of the RR tracks and on the gentle snowy slope SW of Birdseye Rd.
