High frequency

Drizzle today, but atleast I'm feeling better, yesterday was a bit of a washout. The blackbird was listening to another bird's high pitched call, and then replied in a similarly high tone. Having read Bird Sense by Tim Birkhead I now know that a high pitch is not easily heard by larger preditory birds, so maybe a sparrowhawk was in the area.
More spoon making today, so not all wasted!
Will backblip the last few days.
