Pieced together from ancient legends by: David Morgan-Mar
The author writes:
My field guide says that these birds migrate into the region in spring, but they're coming from the opposite hemisphere, so it actually means spring in that hemisphere... as I discovered too late.
So yes, this strip unfortunately marks the first scientific inaccuracy ever to appear in Postcard. Those birds in the background really shouldn't be there at all at this time of year.
Although I think I might resolve this with another polar axis shift. It'll have to happen before this strip in the chronology, but I don't really see that as a problem.
