In the predawn today, a Northern Shrike singing. A series of wonderful, vaguely thrasher like sounds somewhere between a squawk and a blat. After the shrike flew, I became of aware of soft 'shreeing' and discovered a flock of 88 Bohemian Waxwings perched close together and very still in the tops of adjacent trees. As the sun rose and they emerged into color and exquisite form, their calls became louder and they more restive, finally flying off in several waves. In the midst of all this, the local pair of Ravens pair flying overhead, 'crukking' softly to each other, their wingbeats loud in the stillness. Background of singing Redwings.
